HS 280429

Rare Gases Other Than Argon (Helium, Neon, Krypton, Xenon & Others)

U.S. imports of rare gases other than argon (helium, neon, krypton, xenon & others) (HS 280429) totaled $13.3M in April 2026, traded with 21 countries.

Last updated: April 2026 data

Neon's critical role in excimer lasers used in semiconductor lithography has elevated this heading's strategic importance well beyond its modest trade volume, while helium (2804290010) underpins cryogenic cooling for MRI machines and superconducting research. The US schedule further distinguishes isotopically pure rare gases at purity of 99% or greater (2804290030) from commercial-grade neon (2804290020) and residual other rare gases (2804290050, 2804290055), reflecting the premium pricing and specialized end-uses of ultra-high-purity material. Canada and Qatar are the primary foreign sources, with China and Germany also significant contributors.

Frequently Asked Questions

How does the US tariff schedule break down rare gases other than argon?

The heading is subdivided into helium (2804290010), neon (2804290020), isotopically pure rare gases at purity of 99% or greater (2804290030), and two residual 'other rare gases' lines (2804290050 and 2804290055). Correct classification depends on the specific gas identity and purity level.

Who are the primary foreign sources of rare gases imported into the US?

Canada and Qatar rank as the top two suppliers under this heading, followed by China and Germany. Portugal also appears among notable sources. Supply concentration for specific gases like neon can shift significantly with geopolitical events affecting production regions.
