U.S. exports of nitrogen (HS 280430) totaled $3.1M in July 2026.
Importers of Nitrogen paid $47K in duties in July 2026 — an effective duty rate of 13% on $368K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataIndustrial nitrogen — classified under a single line (2804300000) — serves as an inert blanketing and purging gas across electronics manufacturing, food packaging, chemical processing, and cryogenic applications, with demand closely tracking semiconductor and food-industry production cycles. Taiwan leads US import supply for this heading, a reflection of the integrated industrial-gas supply chains serving the semiconductor sector. Like argon, nitrogen is an air-separation byproduct, so its availability and import pricing are influenced by the operating economics of large cryogenic plants rather than dedicated nitrogen production.

Nitrogen is imported as compressed gas (UN 1066) in high-pressure cylinders or tube trailers, or as liquid nitrogen (UN 1977) in cryogenic ISO tanks. Liquid nitrogen shipments require cryogenic handling equipment and specialized storage at the receiving facility. DOT hazmat regulations apply to both forms, and importers must ensure that container certifications and shipping documentation match the physical state of the product.
Semiconductor fabrication requires ultra-high-purity nitrogen (often 99.9999%+) for wafer processing, equipment purging, and cleanroom environments. Fabs consume nitrogen in very large volumes continuously, and because on-site air-separation units cannot always meet peak demand or purity requirements, imports — particularly from integrated industrial-gas suppliers in Taiwan — supplement domestic production. Capacity expansions in US chip manufacturing are expected to increase domestic nitrogen demand further.
