Last updated: April 2026 dataTanker trailers and semi-trailers — engineered to transport liquids, gases, or bulk powders — are classified by their tank-body design rather than the commodity they carry, distinguishing them from flatbed or enclosed cargo trailers. DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) specifications govern tank construction standards for units intended to carry hazardous materials in US commerce, and imported tankers must meet these standards or be brought into compliance before use. The specialized manufacturing requirements for food-grade, chemical, and cryogenic tankers mean that a relatively small number of countries produce units meeting US market specifications.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Tanker trailers used to transport hazardous materials in the US must conform to DOT/PHMSA specification standards (such as DOT-406, DOT-407, or MC-331 series). Imported units that do not bear the required specification markings or certifications cannot be used for hazmat transport and may require costly retrofitting or recertification.
For SITC classification purposes, the tank-body design — not the cargo — determines the heading. However, for regulatory compliance, the intended cargo (food-grade liquids, chemicals, cryogenic gases, etc.) dictates which PHMSA specification applies and may trigger additional FDA or EPA oversight if the trailer is used in food or chemical supply chains.
