U.S. imports of hydrogen (HS 280410) totaled $8.8M in April 2026, traded with 3 countries.
Importers of Hydrogen paid $15K in duties in April 2026 — an effective duty rate of 14% on $108K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataHydrogen's role as both an industrial feedstock — in ammonia synthesis, petroleum refining, and methanol production — and an emerging clean-energy carrier gives heading 280410 growing strategic importance in US trade policy discussions. Classified under a single line (2804100000), imported hydrogen arrives primarily from Canada, which supplies via pipeline and compressed-gas transport to adjacent US industrial regions. DOT hazardous-materials regulations govern transport of compressed or liquefied hydrogen, and importers should monitor evolving DOE and EPA frameworks around clean-hydrogen certification that may affect future trade flows.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Compressed hydrogen (UN 1049) and liquid hydrogen (UN 1966) carry different DOT hazmat classifications, container specifications, and placarding requirements. Liquid hydrogen requires cryogenic dewars and specialized handling at the port of entry, while compressed hydrogen typically moves in high-pressure tube trailers or cylinders. Importers must ensure that the declared form matches the actual shipment to avoid hazmat compliance violations.
Hydrogen used as a fuel or energy carrier may fall within DOE program frameworks, particularly as federal clean-hydrogen initiatives develop certification and tracking requirements. While standard industrial hydrogen currently enters under routine CBP procedures, importers involved in hydrogen-as-fuel supply chains should monitor DOE rulemaking and any future import-authorization requirements that may emerge from clean-energy legislation.
