Limited quantity doesn’t mean limited responsibility
When you hear the term “limited quantity,” it might sound like a way to sidestep the rules, however that’s not the case. Materials shipped under the limited quantity exception are still considered hazmat. They’re just excepted from some of the requirements in the hazardous materials regulations (HMR), especially when transported by ground.
So, what’s different? For starters, limited quantity shipments don’t require hazmat labels, placards, or shipping papers when shipping by highway or rail. That’s a big relief for shippers and carriers who deal with small amounts of hazmat and don’t want to be burdened with all the extra hazmat requirements.
However, and this is important, they’re not exempt from everything.
What's still required?
Even though limited quantity shipments get a break from some of the paperwork and labeling regulations, they still need to meet several important hazmat requirements:
Training: Anyone involved in preparing, handling, or transporting limited quantity shipments must be trained in accordance with the HMR. That includes general awareness, function-specific, safety, security, and driver training.
Packaging: Limited quantity materials must be shipped in combination packaging, which means inner containers (like bottles, cans, or vials) placed inside a strong outer package. In most cases, the gross weight of the outer package cannot exceed 66 pounds.
Marking: Limited quantity packages must be marked with the limited quantity marking, which is a black and white square-on-point symbol. This helps carriers and emergency responders quickly identify the nature of the shipment.
If you’re shipping by air or vessel, the rules get stricter. You’ll need to follow additional requirements, including documentation and labeling, because the risks and regulations differ from ground transport.
Why the exception exists
The limited quantity exception is designed for smaller amounts of hazardous materials that pose a lower risk during transport. By reducing the regulatory burden on these shipments, the DOT allows businesses to move goods more efficiently without compromising safety.
However, it’s not a free pass. Shippers and transporters still need to understand the rules, train their employees, and package and mark their shipments correctly. Otherwise, they risk violations, fines, and potentially unsafe conditions.
Common misunderstanding
One of the most frequent mistakes shippers and transporters make is assuming that limited quantity means “non-hazmat.” It doesn’t. These materials still meet the definition of a hazardous material, they’re just eligible for certain exceptions. That misunderstanding can lead to skipped training, improper packaging, or missing markings, all of which can result in regulatory penalties or safety risks. If your team handles limited quantity shipments, it’s worth reviewing your procedures to make sure you’re not overlooking the requirements that still apply.
Key to remember: If you’re shipping hazardous materials in small quantities, the limited quantity exception can be a helpful tool, if you use it correctly. Remember, limited quantity is still hazmat, and that means the responsibility to ship safely and compliantly still applies.
