U.S. exports of rare gases other than argon (helium, neon, and others) (HS 280429) totaled $80.7M in July 2026.
Importers of Rare Gases Other Than Argon (Helium, Neon, and Others) paid $156K in duties in July 2026 — an effective duty rate of 5.4% on $2.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Rare Gases Other Than Argon (Helium, Neon, and Others) imports of $9.6M in July 2026 ran 28% below the year-to-date monthly average of $13.3M.
Last updated: July 2026 dataHeading 280429 covers the non-argon noble gases — helium, neon, krypton, and xenon — each with distinct supply chains and strategic importance. The US schedule subdivides the heading into helium (2804290010), neon (2804290020), isotopically pure rare gases at 99%+ purity (2804290030), and other rare gases (2804290050 and 2804290055). Canada and Qatar are the leading suppliers, reflecting helium's origin in natural gas processing, while neon — critical for semiconductor laser lithography — has historically sourced heavily from Ukraine-based air-separation plants, creating well-documented supply-concentration risk. Importers of isotopically pure rare gases should pay particular attention to the purity threshold that triggers classification under 2804290030.

Line 2804290030 applies to isotopically pure rare gases with a purity of 99% or greater by isotopic composition. This is a distinct concept from chemical purity — it refers to the isotopic uniformity of the gas, which matters for nuclear, medical imaging, and scientific applications. Importers of isotopically enriched krypton-85, xenon-136, or similar products should confirm isotopic purity documentation to support correct classification.
Neon used in semiconductor excimer laser lithography has historically been produced as a byproduct of steel-industry air separation in Eastern Europe, creating a concentrated supply base. Disruptions to that region's industrial output have prompted chipmakers and gas distributors to accelerate diversification toward US domestic production and alternative international sources. Importers relying on neon for semiconductor manufacturing should maintain multi-source supply agreements and strategic inventory buffers.
