What does 49 CFR 173.6 (Materials of trade exceptions) require?

Short answer

49 CFR 173.6 requires that materials of trade be transported in conformance with specific packaging, hazard communication, and aggregate gross weight requirements. The regulation limits the amount of materials that can be transported and specifies how they must be packaged, marked, and labeled.

The rule says

"A material of trade is limited to the following: (1) A Class 3, 8, 9, Division 4.1, 5.1, 5.2, or 6.1 material contained in a packaging having a gross mass or capacity not over (i) 0.5 kg (1 pound) or" (49 CFR 173.6(a)(1))

"Packagings must be leak tight for liquids and gases, sift proof for solids, and be securely closed, secured against shifting, and protected against damage." (49 CFR 173.6(b)(1))

"The aggregate gross weight of all materials of trade on a motor vehicle may not exceed 200 kg (440 pounds)." (49 CFR 173.6(d))

In plain English

However, there are still specific requirements that must be followed, including packaging, labeling, and weight limits. For example, the materials must be packaged in a way that prevents leakage or shifting, and the total weight of all materials on a vehicle cannot exceed 440 pounds. Inspectors will check for compliance with these requirements during audits and inspections.

What to do

• Ensure that materials of trade are properly packaged and labeled
• Verify that the aggregate gross weight of materials on a vehicle does not exceed 200 kg (440 pounds)
• Train drivers and personnel on the requirements for transporting materials of trade
• Review and update company policies and procedures to ensure compliance with 49 CFR 173.6
