Shippers Beware: New USPS Dimensional Pricing Coming June 23

In this article

Join 26,741 eCommerce Leaders Today

The second phase of the United States Postal Service changes kicks in on June 23, 2019. USPS is changing the way it charges for boxes shipped via Priority Mail, Priority Mail Express as well as new international weight limitations. Currently, USPS applies a dimensional divisor (DIM) of 194 for boxes that exceed one cubic foot in volume, and DIM only applies to zones 5 and above. Starting June 23, 2019, the DIM divisor will be reduced to 166 and will apply to ALL zones (local and 1-9) for Priority Mail, Priority Mail Express and Parcel Select.

The second phase of the United States Postal Service changes kicks in on June 23, 2019. USPS is changing the way it charges for boxes shipped via Priority Mail, Priority Mail Express as well as new international weight limitations. Currently, USPS applies a dimensional divisor (DIM) of 194 for boxes that exceed one cubic foot in volume, and DIM only applies to zones 5 and above. Starting June 23, 2019, the DIM divisor will be reduced to 166 and will apply to ALL zones (local and 1-9) for Priority Mail, Priority Mail Express and Parcel Select.

The first phase of USPS rate hike went into effect in January earlier this year.

Retailers doing order fulfillment must also provide dimensions when the package cubic volume measures over one cubic foot (1,728 inches) while generating labels. Shippers are also encouraged to provide dimensions for all packages and allow for configurable dim divisors to support future changes. Negotiated Service Agreements (NSAs) will be allowed to have a configurable dim divisor for each Zone at this present time.

If you are a USPS shipper, this will impact you. Let’s see this via the following example.

Dimensions
Old Price
New Price (effective June 23)
Price Increase
15 x 12 x 10
10 Pounds (194 DIM) = $26.85*
11 Pounds (166 DIM) = $29.00*
$2.15 (8% INCREASE)

*Priority Mail Retail Rates to Zone 5

While the DIM change from 194 to 166 will certainly impact some postal shippers, it’s important to know that the Postal Service will continue to apply actual weight for packages that don’t exceed one cubic foot in volume. That is, if the cubic volume of a box doesn’t exceed 1728 inches, the charge will continue to be based on the actual weight (not DIM weight).

That’s not all. The Postal Service will also revise the weight limitation for First-Class Mail International (FCMI) flat pieces to 15.994 oz. to more closely align the definition of FCMI large envelopes (flats) with that of the Universal Postal Union Conventions.

For FCMI flats that are over 15.994 oz., USPS will not process those as FCMI starting June 23, instead, you will need to classify and mail those pieces under First-Class Package International Service (FCPIS).

You could alternatively elect to use another class of mail such as Priority Mail Express International or Priority Mail International, if the mail piece meets the requirements for those mail classes.

Below are few strategies for offsetting the impact of the new DIM billing:

1.    Move package volume from USPS to FedEx/UPS or other parcel carriers. High-volume shippers can negotiate deeper discounts and more favorable DIM divisors. Many regional carriers offer shipper-friendly DIM divisors compared to the large national carriers. The large national carriers right now may be more open to offering special incentives to shippers as they try to offset the loss of business from Amazon.

2.    Try to get commercial base pricing (CBP) or commercial plus pricing (CPP). Most Cahoot merchants qualify for special CBP and CPP pricing; please contact us if you are not enjoying these rates already. High-volume shippers can get even deeper discounts by pursuing a negotiated services agreement (NSA) with the Postal Service or through authorized postal resellers. These discounts could offset DIM increases, at least in the short-term.

3.    Improve packaging. By reducing excess box dimensions and minimizing fill, shippers can reduce the impact of dimensional pricing, reduce corrugated and packing material costs, and reduce carbon emissions.

4.    Optimize via Cahoot. By joining Cahoot’s innovative peer-to-peer ecommerce order fulfillment networkTM, you can convert say a zone 8 shipment to a zone 2 shipment. You save big which more than makes up for any DIM billing increase, plus the packages get delivered to your customers faster.

If you haven’t yet considered the impact of the upcoming June 23 changes, you could be looking at an 8 percent-plus increase on some or more of your USPS packages. Please contact a Cahoot Expert, if you need help or would like to learn more.

The Ecommerce Merchant’s Guide to UPS 2nd Day Air

In this article

9 minutes

Join 26,741 eCommerce Leaders Today

UPS offers a host of services to ensure that your packages are delivered quickly to customers. Small improvements in which service you pick can have a big impact on customer experience and profitability, so in this guide we’ll walk you through your options and how to make the right choice for your business.

What is UPS 2nd Day Air?

As customer expectations for fast shipping increase, services like UPS 2nd Day Air gain prominence. UPS 2nd Day Air is an alternative for businesses that require fast, but not overnight delivery. It’s simple – slow delivery speeds blunt online store growth because products with slow shipping are added to carts less frequently, and their carts are abandoned more often than products that ship quickly. A 2023 Hanover Research study found that 86% of online shoppers see 2- to 3-day delivery as the baseline, and 63% say they would switch retailers if they could not receive their items within this timeframe.

UPS 2nd Day Air is one of a few expedited shipping options from UPS, and they describe it as their “economical option for shipments that do not need overnight service”. Designed to meet domestic shipping needs across the continental United States and Puerto Rico, 2nd Day Air ensures that a package will arrive at its destination in two business days but the ‘type’ of 2nd Day Air you choose will affect the delivery time.

UPS-Cargo-Planes

UPS 2nd Day Air provides day definite delivery; ensuring packages arrive within a specified timeframe. But there are two different types of 2nd Day service – standard service and AM. When someone absolutely needs an item first thing in the morning, you need to spring for the much more expensive 2nd Day Air AM. Without 2nd Day Air AM, UPS only guarantees an end-of-day delivery time, which can of course stretch late into the night.

In addition to 2nd Day Air, UPS also offers 1-day and 3-day expedited services. The 1-day service is called UPS Next Day Air, and as you can imagine the 3-day service is called UPS 3 Day Select.

Benefits of Using UPS 2nd Day Air

UPS 2nd Day Air is a popular shipping option for businesses that need to deliver products quickly and efficiently. Here are some benefits of using UPS 2nd Day Air:

  • Fast Delivery: UPS 2nd Day Air guarantees delivery by the end of the second business day, making it an ideal option for businesses that need to deliver products quickly. This ensures that your customers receive their orders promptly, enhancing customer satisfaction and loyalty.
  • Cost-Effective: Compared to overnight shipping, UPS 2nd Day Air is a more cost-effective option. It allows businesses to save on shipping costs while still providing expedited delivery. This balance between speed and cost can be crucial for maintaining profitability in a competitive market.
  • Reliable: With UPS 2nd Day Air, you get the peace of mind that comes with guaranteed delivery. UPS guarantees delivery within two business days, ensuring that your packages arrive on time and reducing the risk of delays that could impact your business operations.
  • Flexible: UPS 2nd Day Air offers a range of shipping options to meet different needs. Whether you require morning delivery, afternoon delivery, or residential delivery, UPS has you covered. This flexibility allows businesses to cater to various customer preferences and special delivery instructions, enhancing the overall shopping experience.

UPS 2nd Day Air Delivery Times

UPS 2nd Day Air delivery times vary depending on the destination and the time of day the package is shipped. Here are some general guidelines for UPS 2nd Day Air delivery times:

  • Business Days: UPS 2nd Day Air delivery times are based on business days, which are Monday through Friday and do not count the date of shipment. This means that packages shipped on a Friday will typically be delivered by the end of the day on the following Tuesday.
  • Delivery Begins: Delivery begins at 10:00 am, and the first packages are typically received by 10:30 am. This early start ensures that businesses can receive their shipments promptly and begin processing them without delay.
  • Afternoon Delivery: For those who prefer later delivery times, UPS 2nd Day Air offers afternoon delivery, with packages typically arriving by 4:30 pm. This option is ideal for businesses that operate later in the day or for customers who are not available in the morning.
  • Residential Delivery: UPS 2nd Day Air also caters to residential delivery needs, with packages typically arriving by 7:00 pm. This ensures that customers who are not home during the day can still receive their packages in the evening.

Overall, UPS 2nd Day Air is a reliable and cost-effective shipping option that offers fast delivery times and flexible shipping options. Whether you need to meet tight deadlines or provide convenient delivery times for your customers, UPS 2nd Day Air has the solutions to meet your needs.

How Much Does Shipping UPS 2nd Day Air Cost?

Cahoot’s internal shipping metrics show that UPS 2nd Day doesn’t come cheap – in fact, we observe that it’s often roughly two times as expensive as UPS Ground.

If you’re used to paying $8 or $9 to ship your packages via Ground and seeing them take a week to deliver, 2-day delivery is going to cost you somewhere in the upper $10 dollar range. In the hyper-competitive ecommerce world, an extra $5-10 in shipping costs can often be the difference between making and losing money on an order.

UPS 2nd Day Air AM balloons the cost of shipping far beyond the standard version of 2-day. Our data shows that the AM option nearly doubles the cost of standard – so it often comes in at nearly 4 times more expensive than UPS Ground. To us, the small added benefit of an early delivery won’t often justify the large added cost.

How to Ship Fast Without UPS 2nd Day Air

To quickly recap – customers expect fast shipping, so you need to offer it to boost growth. However, fast shipping is prohibitively expensive. If you’re like the vast majority of ecommerce merchants and can’t eat $10 extra in shipping on every single item, you need a better way.

The solution to this riddle is to ensure that you always have inventory close to the customer so that UPS Ground delivers in 1- to 2-days without the extra cost of 2nd Day Air – many call this a “distributed fulfillment strategy”. Typically, this means ensuring that you never ship farther than Zone 4, and it requires ~4 fulfillment locations strategically placed throughout the United States. This simple principle, though, is anything but simple in execution.

USA-Distributed-Fulfillment-Map-1

Here’s the three ways that merchants can adopt a distributed fulfillment strategy:

  1. Open Multiple Fulfillment Centers: merchants can open multiple US fulfillment centers and manage the four walls themselves. While having control may seem appealing, there’s never been a worse time to try to stand up merchant-operated fulfillment. Warehouse rents are hitting record highs, and if you can even find people to work for you, you’ll have to pay them $29.00 per hour to compete with Amazon’s rates. This strategy is also time-consuming and risky – you’ll spend countless managerial hours on operations instead of selling, and you’ll have to tie up significant capital.
  2. Marketplace Fulfillment Services: Amazon and Walmart offer their own in-house fulfillment networks; Amazon FBA and Walmart Fulfillment Services, for sellers on their platform. They enable fast shipping nationwide, and crucially, they allow vendors to place Prime Badges and Walmart TwoDay tags on their listings to boost visibility and conversion. While attractive, these solutions come with significant drawbacks. They’re designed for small products, so FBA is much more expensive for large items, while Walmart doesn’t accept them at all. Additionally, they’ll only solve your fulfillment needs for the marketplace itself. Amazon FBA’s multi-channel solution, Amazon MCF, is significantly more expensive than FBA, while WFS only works for Walmart orders.
    WFS offers 100% 2-day nationwide shipping
  3. Third-Party Logistics Companies (3PLs): Your last option is to outsource fulfillment to one 3PL with national fulfillment services, or to multiple single-location 3PLs. The best 3PLs will have 10 or more locations across the United States, so they can strategically place your inventory right near your customer base. Modern 3PLs designed for ecommerce also have built native integrations with all major marketplaces and shopping carts, so you can use one provider for all of your fulfillment needs. Fulfillment costs will vary between 3PLs, though, and not all of them can meet the strict SLAs needed to win the Buy Box on every marketplace. Be sure to use something like a 3PL request for proposal (RFP) template to get an apples to apples comparison.

The Best Way to Ship Heavy Items: How to Maximize Your Profit

In this article

12 minutes

Join 26,741 eCommerce Leaders Today

If you’re shipping large items, then you know the pain of high storage, handling, fulfillment, and especially shipping costs eating up your margin. While you’ll always pay more to ship a chair than a pen, you shouldn’t resign yourself to eating sky-high rates. With higher shipping costs come larger opportunities to save money; cutting a few dollars of cost off of each order goes straight to your bottom line.

In this article, we’ll cover three of the top ways that you can reduce your cost while shipping heavy and/or large items. Implement them and watch your profit jump and headaches melt away!

Understanding Heavy Item Shipping

Heavy item shipping refers to the transportation of goods that exceed standard weight and size limits. These items require specialized handling, equipment, and logistics to ensure safe and efficient delivery. Whether you’re shipping industrial machinery, medical equipment, or large furniture pieces, understanding the nuances of heavy item shipping is crucial for minimizing costs and maximizing efficiency.

Heavy vs Large Packages

First, we need to make a distinction between heavy and large items. Often large items are heavy, and heavy items are large, but that’s not always the case. When you ship heavy packages, it’s crucial to understand the specific rules, limitations, and pricing options of different carriers to ensure shipping cost-effectiveness and compliance. Improper shipping and handling can also include additional surcharges, double penalizing shipping heavy items. Shipping carriers have specific guidelines and weight thresholds that classify items as heavy, and understanding these definitions can help you choose the right shipping method and carrier.

Definition of Heavy Items in Shipping

Carriers define packages as Heavy if the package weighs more than their normal weight range. For example, UPS charges additional fees for packages weighing more than 70 lbs (31.75 kg), and their maximum allowed parcel weight is 150 lbs.

Definition of Large Items in Shipping

Carriers define packages as Large if the package’s size is more than their normal allowed size range. For example, FedEx’s Large package size starts at a girth greater than 130 inches, and their maximum allowed package length + girth is 165 inches.

Types of Heavy Items

Heavy items typically include furniture, machinery, tools, and other items made of wood or metal. These are typically bulky goods that require special handling and care.

Importance of Proper Shipping for Heavy Items

Proper shipping of heavy items is crucial to ensure safe and efficient delivery. Improper handling and transportation can result in damage to the goods, injury to handlers, and increased shipping costs. Choosing a reliable shipping carrier that specializes in heavy item shipping and follows strict safety protocols is essential. By investing in proper packaging, using heavy-duty packing tape, and selecting the right shipping method, you can minimize risks and ensure your heavy items reach their destination in perfect condition.

Freight (LTL) Shipping Options

Freight shipping is a cost-effective way to transport heavy items over long distances. There are several freight shipping options available, each offering unique benefits and services tailored to meet the needs of shipping large and heavy items. For items that are too heavy to ship via parcel, freight shipping is the best option.

Overview of Freight Shipping Services

Freight shipping services offer a range of benefits, including:

  • Cost-effectiveness: Freight shipping is often cheaper than parcel shipping for heavy items. By consolidating shipments and using specialized equipment, freight carriers can offer competitive rates for transporting large and heavy items.
  • Flexibility: Freight shipping services can accommodate a wide range of goods, including oversized and heavy items. Whether you’re shipping machinery, equipment, or furniture, freight carriers have the expertise and resources to handle your shipment.
  • Reliability: Freight shipping services provide tracking and monitoring to ensure safe and efficient delivery. With advanced logistics and real-time tracking, you can stay informed about the status of your shipment and ensure it arrives on time.

Some popular freight shipping services include:

  • DHL Freight: Offers a range of freight shipping services, including ocean freight and air freight. DHL Freight specializes in international shipping and provides comprehensive solutions for transporting heavy items across borders.
  • UPS Freight: Provides freight shipping services for heavy items, including machinery and equipment. UPS Freight offers a variety of shipping options, including LTL (less-than-truckload) and FTL (full-truckload) services, to meet your specific needs.
  • FedEx Freight: Offers freight shipping services for heavy items, including furniture and oversized goods. FedEx Freight provides reliable and efficient shipping solutions, with options for expedited and standard delivery.

When shipping heavy items, it is essential to choose a reliable freight shipping service that meets your specific needs and budget. Be sure to compare shipping rates, weight limits, and express services to find the best option for your heavy item shipping needs. By selecting the right freight carrier, you can ensure your heavy items are transported safely and cost-effectively.

Distribute Inventory to Reduce Shipping Zones

To state the obvious, the farther you’re sending a package, the more you’ll be charged. Within the continental United States, shipping distance is governed by Zones. Short trips will be designated Zone 2, while shipping something across the country will usually be designated Zone 8.

If you’re fulfilling out of just one warehouse, you have no choice but to routinely ship to Zones 5 and up, which is especially costly with large or heavy packages. Even with two warehouses, much of the country will be outside of the low-cost Zones 2 & 3.

The simple trick is to ensure that you always have inventory close to the customer so that every shipment originates from Zone 4 or less; many call this a “distributed fulfillment strategy”. It requires 3 to 4 fulfillment locations strategically placed throughout the United States. Cutting your average shipped-to zone will drive savings straight to your bottom line.

Distributed fulfillment also comes with the enormous added benefit of enabling fast ecommerce order fulfillment – after all, if your product isn’t shipping far, then it won’t take more than 1 or 2 days to get to the customer. You can stop worrying about using extremely expensive services such as UPS 2nd Day Air and pay ground rates for customer-pleasing fast delivery.

This simple principle, though, is anything but simple in execution.

USA-Distributed-Fulfillment-Map-1

Based on Ground Shipping speeds

If you already have one warehouse, then it can be tempting to take it upon yourself to open 1-2 more US fulfillment centers across the country. While maintaining control of your customer experience is appealing, there’s never been a worse time to try to stand up merchant-operated fulfillment. Warehouse rents are at record highs, and Amazon has pushed the cost of labor as high as $29.00 per hour.

If you’re a marketplace seller, then you may already be using Amazon and Walmart’s in-house fulfillment networks; Amazon FBA and Walmart Fulfillment Services. These services will solve the distributed inventory challenge for you and enable fast shipping, but they also come with significant drawbacks. They’re designed for small products, so they both significantly raise prices for large items. Walmart, for instance, charges all items with a side length of over 96 inches or a combined length and girth over 130 inches as at least 90 lb no matter their actual weight, and then they add a $25 surcharge to boot. Additionally, they’ll only solve your fulfillment needs for the marketplace itself. Amazon FBA’s multi-channel solution, Amazon MCF, is significantly more expensive than FBA, while WFS only works for Walmart orders.

Walmart-Oversize-Fulfillment-Fees

Your last option is to outsource fulfillment to one 3PL with national fulfillment services, or to multiple single-location 3PLs. The best 3PLs will have 10 or more locations across the United States, so they can strategically place your inventory in the perfect position for your customer base. Modern 3PLs designed for ecommerce also have built native integrations with all major marketplaces and shopping carts, so you can use one provider for all of your fulfillment needs. Fulfillment costs will vary between 3PLs, though, and not all of them can meet the strict SLAs needed to win the Buy Box on every marketplace. Be sure to use something like a 3PL request for proposal (RFP) template to get an apples to apples comparison.

Ship Heavy Items with the Right Carrier

Not every carrier is created equal when it comes to shipping heavy items, and relatively small adjustments in your package size and weight can have big implications when it comes to choosing the most cost-effective option.

FedEx’s guidelines on how to ship oversize items detail that they add an oversize shipping fee when packages have a girth of more than 130 inches. Note that if a package is over 150 lbs, or if its combined length and girth is more than 165 inches, then FedEx will classify it as freight and apply a completely different set of rules.

UPS governs its large items a bit differently. It will designate a package as “Over Maximum Size” when its length plus girth combined exceeds 165 inches, and charge additional fees. UPS charges additional fees for packages over 70 lbs and has a maximum package weight is 150 lbs.

Finally, USPS is less equipped to ship large packages, and thus has more restrictive rules. Their maximum size for most mailpieces is 108 inches in combined length and girth, but USPS Retail Ground has a slightly larger allowance of 130 inches. Regardless of size, the maximum mailable weight of any mailpiece sent through USPS is 70 lbs. Packages that are between 108 and 130 inches in combined length and girth are subject to a special oversized price on USPS.

These guidelines leave wiggle room for savvy merchants to optimize their shipping costs. Note that FedEx’s oversize charge only kicks in on packages with a girth of more than 130 inches, while UPS and USPS have lower limits. On top of that, the latter two’s limits are based on combined length and girth. If your package fits under FedEx’s bar for oversize, but over the bars for the other carriers, then you know that you can avoid surcharges by shipping with FedEx.

You can take it upon yourself to negotiate with the carriers separately, or if you’re using shipping software like ShipStation, you can set manual rules and rate shop to scrutinize your orders for the best rates. On the other hand, our next-gen shipping software will do the hard work for you by automatically comparing major and regional carriers against each other for each order. Without any manual intervention, the software will take quirks like differences in surcharges into account and ensure that you’re getting the best deal, every time.

Optimize Package Size

Small changes in package size can make a big difference to your final shipping cost. When you’re shipping large and oversize items, every additional pound usually adds $0.30 – $0.50 to your cost, which adds up quickly!

Package size matters because of Dimensional Weight, or DIM weight for short. Major carriers introduced DIM weight around 2015 as a way to charge more for bulky, yet light products. The calculation is fairly simple: DIM weight is equal to L x W x H of your package, divided by 139 (166 for USPS). If the resulting number is larger than the weight of the package in pounds, then the shipping weight used to calculate price will be elevated to the DIM weight.

How-to-Calculate-DIM-Weight

In this way, inefficiencies in package design quickly add up to boost your shipping cost to well more than it should be.

Consider a package that is 24 x 24 x 24. This 2 ft cube package’s DIM weight is 99.45 lbs. If you’re shipping two pillows in that package, the actual weight is probably less than a tenth of the DIM weight. In that scenario, DIM weight increases your cost by $30 or more! What if you could shave 4 inches off one of the sizes by more efficiently compacting your pillows?

Those 4 simple inches cut the DIM weight all the way down to 82.88 lbs, a nearly 20% reduction. That package would fall into FBA’s “Medium oversize” category, with a shipping weight between 70 – 150 lbs. FBA’s fulfillment fee rises by $0.44 for each pound in that category, so shaving the 4 inches off of one side of the package would save you over $7 per order.

Frequently Asked Questions

What is the cheapest way to ship heavy items?

This depends on the size of the item. For smaller items, USPS Priority Mail can be cost effective, and for larger items, UPS or FedEx is usually cheaper.

Are there any special instructions when shipping heavy items?

Heavy items can do more damage when moving in transit; proper packaging and dunnage help keep heavy items protected in shipping.

1. The Changing Landscape of Ecommerce Shipping

Two decades ago, ecommerce was a different world. Online Sellers operated on a single channel, faced minimal competition, and customers had lower expectations. Shipping was simple: businesses worked with a single carrier, operated from one warehouse, and didn’t have to worry about complex fulfillment logistics.

Fast forward to today, and the ecommerce landscape has changed dramatically:

  • Sellers operate across multiple channels like Amazon, Walmart, and Shopify.
  • Competition is intense, requiring fast, free shipping to stay ahead.
  • Customers expect 1‑2 day delivery, forcing Sellers to distribute inventory across multiple warehouses.
  • Carrier rate increases (GRIs) have made it more expensive to ship orders profitably.

With this growing complexity, businesses can no longer rely on legacy shipping software that lacks automation, intelligent decision‑making, and scalability. Next‑gen ecommerce shipping software is purpose‑built for today’s challenges, offering automated order routing, real‑time carrier rate shopping, and seamless multi‑channel integration to optimize fulfillment workflows.

Understanding Hazardous Materials Regulations

Navigating the landscape of hazardous materials regulations is crucial for ensuring the safe and secure transportation of these potentially dangerous goods. These regulations are meticulously designed to prevent accidents, injuries, and environmental damage during the transportation process.

In the United States, the Department of Transportation (DOT) plays a pivotal role in regulating the transportation of hazardous materials. The DOT’s Hazardous Materials Regulations (HMR), found in Title 49 of the Code of Federal Regulations, outline comprehensive guidelines for the classification, packaging, and labeling of hazardous materials. These regulations ensure that hazardous materials are properly identified and handled with the utmost care.

The HMR mandates that hazardous materials must be accurately classified, appropriately packaged, and clearly labeled before transportation. Additionally, individuals involved in handling these materials are required to undergo proper training to adhere to established safety procedures. This training is essential for minimizing risks and ensuring compliance with regulatory standards.

Beyond the DOT, other regulatory bodies also contribute to the safe handling of hazardous materials. The Occupational Safety and Health Administration (OSHA) enforces regulations that govern the handling of hazardous materials in the workplace, ensuring the safety of employees. The Environmental Protection Agency (EPA) oversees the transportation of hazardous waste, further safeguarding public health and the environment.

By adhering to these regulations, individuals and organizations can significantly reduce the risk of accidents and injuries, while also protecting the environment. Compliance with hazardous materials regulations is not just a legal obligation but a critical component of responsible and safe transportation practices.

What is a Hazardous Material?

For many ecommerce brands and sellers, there are already lots to think about when shipping orders – you need to send inventory to warehouses, have shipping labels printed, and pick, pack and ship items correctly.

However, some sellers sell products that require extra diligence, care, and attention while shipping them. Shipping Hazardous Materials, or HAZMAT as they’re commonly called, can be complex. In January 2025, the United States Postal Service (USPS) announced a number of changes to the guidelines sellers have to follow while shipping HAZMAT items. Following these guidelines is important for sellers to maintain compliance and mitigate regulatory risks, while also ensuring the safety of USPS staff who ship and deliver your packages.

A lot of sellers may not be aware of the extent and impact of these new changes. Failing to comply with the new requirements can cause significant damage to your brand. In this article, we’ve compiled everything you need to know about HAZMAT shipping.

We start by understanding the definition of a hazardous material and what items are classified as HAZMAT. We then take a deep-dive into how the Postal Service was handling HAZMAT previously and what has changed in the latest requirements. We examine why the USPS might be making these changes and the potential penalties you face for non-compliance. Lastly, we look at what your fulfillment partner (3PL) must do to ship hazmat orders in a compliant manner, keeping your brand, USPS personnel, and your customers safe.

What Items Are HAZMAT?

The Postal Service classifies every hazardous material into one of nine categories.

Common hazardous materials that are regulated include:

  • Combustible liquids
  • Hazardous substances
  • Lithium batteries
  • Lithium ion batteries
  • Hazardous waste
  • Hazardous wastes
  • Common hazardous materials

Proper packaging of hazardous materials packages is crucial to ensure compliance with safety standards and prevent leaks or spills during shipping.

What Changes Have USPS Recently Made to Hazardous Materials Regulations?

Recently, the USPS has been making a number of changes to the way it handles and processes HAZMAT shipping.

These have important implications for sellers. In this section, we take a look at each of them:

Declaring HAZMAT During Label Generation

USPS now requires shippers to officially declare that packages contain HAZMAT when they purchase shipping labels.

The shipping label consequently clearly indicates this, making it easy for USPS staff to handle the shipment with the required care. Proper documentation is essential for transporting hazardous materials safely and in compliance with regulations.

Items Allowed on Ground vs. Air

Recently, USPS has begun restricting electronic devices that are used, damaged, or defective to ground services alone.

These packages must now be labeled as ‘Restrictive Electronic Devices’ for ‘Surface Transportation Only’.

Separation of HAZMAT And Non-HAZMAT Items

The USPS has also begun requiring that HAZMAT and non-HAZMAT items must be clearly separated into different parcels or mail receptacles. The HAZMAT parcels need to have clear marking and identification.

Why Have These Changes Been Made?

Why is there suddenly an increased focus on these compliance requirements from the Postal Service? Many shippers have been used to operating without any changes to requirements for a long time and might be surprised about why these changes are taking place now.
In this section, we’ll take a look at why USPS is enforcing these new requirements, as well as the risks you face if you don’t comply with them.

Safety of USPS Personnel and Transportation

Hazmat-Compliance-Ensure-Safety-of-USPS-Personnel-and-Transportation

According to Shippo’s estimates, over 10,000 safety incidents involving HAZMAT shipping were reported in the first nine months of the 2020 fiscal year. That number has continued rising – in 2022, there were over 25,000 HAZMAT incidents reported.

Such incidents pose significant risks for USPS personnel, the environment, property, and other people sharing the road or airspace during their transportation. In a bid to reduce this impact and improve overall safety outcomes, these new requirements are being enforced.

More Reliable On-Time Delivery

While these incidents are detrimental from a health and safety perspective, that isn’t their only negative. They disrupt operations and delay deliveries. In fact, Shippo estimates that packages are delayed by an average of 2 weeks after such incidents.

With USPS aiming to compete more aggressively in parcel delivery with the likes of UPS and FedEx, an increasing accident rate can lower their delivery SLAs and affect service levels for all shippers.

USPS’ latest regulations are aimed at streamlining their network operations and reducing downtime and disruptions.

Penalties For Non-Compliance

As the number of HAZMAT shipping related incidents is on the rise, failure to comply could affect your brand’s ability to conduct operations normally. With health, safety, and lives at stake – the penalties for noncompliance are heavy. Here are the possible penalties:

  • Your shipments could be denied entry into the USPS mailstream – affecting your ability to meet customer delivery promises.
  • For serious infractions, the US Department of Transportation can pursue civil penalties.
  • The maximum penalty for Hazardous Materials violation is $89,678. However, if the violation results in death, serious illness, severe injury to an individual or significant damage to property, you could be fined as much as $209,249.

Such incidents can be financially damaging, affect your brand’s reputation and in some cases even threaten its very existence.

What Should You and Your 3PL Do While Shipping HAZMAT?

The first question you might have is – which of my SKUs are HAZMAT? The quickest way to identify this is using the Product Safety Data Sheet (SDS). What is a Safety Data Sheet?

Identify Your HAZMAT SKUs Using Product Safety Data Sheets (SDS)

A Safety Data Sheet (SDS) is a document that provides detailed information about the properties, hazards, and safe handling procedures of a product. It includes essential details such as the product’s composition, physical and chemical characteristics, potential health and environmental hazards, safe usage guidelines, emergency response measures, and regulatory information.

You can use the SDS database to locate your product’s safety sheet.

On it, you’ll need to go to Section 14, which provides transportation information, including the category that DOT classifies the product under. Using this, you can understand which USPS services can be used to ship the item, as well as specific marking/labeling, and packaging requirements.

Properly Designate HAZMAT SKUs on Shipping Software

You need to designate your HAZMAT SKUs on your shipping software. This is important for a number of reasons:

  • This can be transmitted to USPS when purchasing labels, so that they know you are shipping HAZMAT.
  • It helps your fulfillment partner affix the right marking/labels when packing these items.
  • It helps your fulfillment partner package these items the right way.

Having your SKUs properly designated on a digital system of record is the best way to ensure defect-free, compliant fulfillment. Relying on spreadsheets or human-to-human conversation can lead to potentially costly lapses.

Adhere to Packaging Requirements

Hazmat Warning Stickers

While shipping HAZMAT, you must make sure to follow packaging requirements to keep your items secure and spill or leak-proof.

Your fulfillment partner must have deep knowledge of what HAZMAT SKUs you are shipping, and then package them in accordance with the specific requirements laid out in Appendix C of Publication 52.

While the details can vary significantly based on the item, these are broad best-practice guidelines applicable across most items. Following these packaging practices requires industry-leading fulfillment standards from your 3PL. Warehouse staff must make sure to diligently pack each SKU in the best possible way on every order.

Inner Packaging

  • Employ inner packaging that is compatible with the specific hazardous material but also capable of withstanding the conditions of transportation.
  • Inner packaging must be leak-tight for liquids and gas-tight for gasses, preventing unintended release during transit.

Outer Packaging

  • Utilize robust outer packaging that serves as a primary barrier to protect the inner packaging and the contents from external forces and potential hazards.
  • All HAZMAT and Dangerous Goods need to ship in rigid outer packaging that meets minimum edge crust test (ECT) requirements:
    • Packages weighing 20 lbs or less: ECT of at least 32, burst strength of 200 lbs.
    • Packages weighing more than 20 lbs: ECT of at least 44, burst strength of 275 lbs.
  • Choose outer packaging materials that are suitable for the specific characteristics of the hazardous material being shipped.

Cushioning and Absorption

  • An effective cushioning system safeguards the inner packaging from movement and potential damage during transit, providing an additional layer of protection.
  • For liquids, incorporate absorbent materials within the packaging to contain and manage spills, preventing leakage that could pose safety and environmental risks.

Closure and Sealing

  • Ensure secure closure and sealing of packages to prevent any leakage or spillage during transportation.
  • Verify that closures meet regulatory standards and are appropriate for the specific hazardous material being shipped, maintaining the integrity of the package.

Overpack Requirements

  • If applicable, employ overpacking techniques as an additional layer of protection and consolidation for smaller packages.
  • Overpacks should not only consolidate packages but also be designed to contain leaks or spills, providing an extra measure of safety.

Separation of HAZMAT

  • Package hazardous materials with a keen focus on preventing any reactions between different substances within the package.
  • Separation of incompatible materials within the packaging ensures that any potential chemical reactions are avoided, maintaining the safety and stability of the shipment.

Quantity Limits

  • Adhere strictly to quantity limits specified for each hazardous material to prevent overloading and ensure compliance with safety regulations.
  • Packaging must be designed to accommodate the specified quantity, preventing any compromise in the safety of the contents.

Adhere to Marking and Labeling Requirements

When shipping HAZMAT items, it is important to affix various marking labels onto the package that provide information to USPS staff about what the package contains.

This helps them handle the package the right way and ensures higher safety standards. While these can vary significantly by product, here are a few common marking/labeling practices required for HAZMAT items. For your specific SKU, make sure to refer to Appendix C of Publication 52.

Your 3PL must be capable of mapping each SKU you have to its specific labeling requirements. This detail-oriented rigor must be backed up by defect-free, high-quality fulfillment standards that ensure each package has all the necessary labels on it.

  • Hazard Class Labels
    • Hazard class labels need to be affixed to the outer packaging, indicating the primary hazard class or division of the material.
    • Ensure hazard class labels are prominently displayed, providing USPS staff a quick visual identification of the potential risks associated with the shipment.
  • Handling Labels
    • Mark packages with handling labels, communicating specific instructions on how to safely handle them during transportation.
    • Clear and concise handling labels contribute to the safe and proper management of the package during transit.
  • Identification Numbers
    • Clearly display proper shipping names and identification numbers on the outer packaging.
    • This information assists in identifying the material and its associated hazards, aiding in emergency response and handling procedures.
  • Limited Quantity Marking
    • If applicable, mark packages with the “Limited Quantity” marking to indicate compliance with quantity limitations for certain hazardous materials.
    • This marking is crucial for packages that qualify for reduced regulatory requirements.
  • Overpack Marking
    • For overpacks, mark them appropriately to indicate that they contain hazardous materials.
    • Overpack markings help handlers and emergency responders quickly identify packages that include multiple smaller packages.
  • Orientation Arrows
    • On packages containing liquids, include orientation arrows to indicate the correct orientation for safe handling.
    • Proper orientation ensures that liquids are transported in a manner that minimizes the risk of leaks or spills.
  • Elevated Temperature Marking
    • If applicable, mark packages containing materials at elevated temperatures to communicate the additional risks associated with heat.
    • This marking ensures awareness of temperature-related hazards during transportation.
