What are the regulations around transporting Lab Packs?

The US DOT regulations at 49 CFR 173.12(b), (d), and (f) include special requirements for transporting lab packs. Firstly, the materials shipped in the lab packs must be of the same DOT hazard and must be compatible. Outer packaging must be UN-performance packaging, typically open-head drums of steel, plastic, other metal, or fiberboard. Each inner container cannot exceed 20 liters capacity, and the total weight of the lab pack cannot exceed 205 kilograms.
