The shipper of a hazardous materials has many responsibilities under the Hazardous Materials Regulations (HMR) of PHMSA/USDOT. One of them is to comply with the applicable requirements of 49 CFR 173, subpart B – Preparation of Hazardous Materials for Transportation. These are sometimes referred to in the HMR as the “general packaging requirements”. The regulations of subpart B primarily apply to the packaging of the HazMat and the responsibility of the shipper for its assembly, loading and/or unloading, its closure, and its use in transportation. It will take more space than I have here to explain all of subpart B. Instead, below I will list the citations and section titles for all of subpart B. If you have a question on any section you see below, please don’t hesitate to contact me for more information.
