Just one of the questions I receive every few days:

Can I haul 400 lbs of 2.1 and 2.2 without placards?

My answer:

Yes. The placarding threshold for those hazardous materials is 454 kg (1,001 lb).

Explanation:

Pursuant to 49 CFR 172.504(c), a transport vehicle or freight container which contains a hazardous material covered by Table 2 in §172.504(e) is not required to display placards unless one of the following is true:

• The HazMat is in a bulk packaging.
• HazMat is subject to §172.505.
• Transport vehicle or bulk packaging contains 454 kg (1,001 lbs) or more aggregate gross weight of HazMat.
