The exception to the requirement that shippers certify packaging occurs when the shipper is a private carrier carrying their own product.

• A. The shipper is a private carrier carrying their own product
• B. The shipment is domestic only
• C. The product is nonhazardous
• D. The quantity is less than 50 pounds

Answer: (A)

Shippers must certify that packaging for hazardous materials meets the required performance standards, ensuring it won’t leak or fail during transport. The exception for a private carrier shipping its own product exists because in that scenario the shipper controls the entire process—the packaging is chosen, tested, and used within the same company for its own shipments. This internal, private freight flow reduces the need for an additional external certification step, since safety controls are already managed by the shipper and the packaging is already aligned with that company’s procedures. Other conditions, like being domestic only, the product being nonhazardous, or the quantity being small, do not create this exemption, so the packaging certification requirement still applies in those cases.
