Transport in North America

The transport of dangerous goods in the USA is regulated by Title 49 of the United States Code of Federal Regulations (49 CFR). Each mode of transport (by road, rail, inland waters, sea and air) is regulated under 49 CFR and enforced by the US Department of Transportation (US DOT).

International laws (i.e., IATA (Air) and IMDG (Ocean)) regulate the transport outside the territory of the country. These regulations have continued to become aligned with the revisions in the Orange Book and additionally allow for the utilization of international regulations when multi-modal transportation activities occur.

Shipments to and from the USA and Canada

A reciprocal agreement is in place for international shipments between the USA and Canada. Hazardous materials (a.k.a. dangerous goods) may be shipped by rail or highway into either country under most of the originating country’s regulations. There may be additional requirements in place for compliance within each country depending upon the mode and the material.

Shipments to and from the USA and Mexico

Shipments to or from Mexico will normally align and comply with all applicable requirements of 49 CFR. There may be additional requirements for shipments transported by rail or highway of certain hazardous substances (e.g., substances that are poisonous by inhalation).
