Liquid Helium for Cryogenic Research
Helium in liquid form at -269°C, supplied in insulated dewars for cryogenic research and dilution refrigerators. The physical state does not affect classification, as it remains the elemental rare gas.

Argon-36 Isotopically Pure Gas Cylinder
Argon-36 gas with 99%+ volume isotopic purity, imported in compressed cylinders for geochronology and stable isotope studies. It is an isotopically pure rare gas.
Argon-38 Calibration Gas
Argon-38 calibration gas is a stable isotope of argon, a rare gas, mixed at trace levels in a 1-liter cylinder for mass spectrometry calibration. It qualifies as a separate chemical element under Chapter 28, as it is not a radioactive isotope and falls under the 'other' rare gases category.
Argon Gas for Welding
High-purity argon gas for welding is a rare gas in elemental form, used as an inert shielding atmosphere in MIG/TIG welding. It falls under tariff item 2804.29.00 as 'other' rare gases, distinct from hydrogen and helium.
Helium-3/Helium-4 Hyperpure Mixture
A hyperpure helium mixture with He-3 isotopically enriched to >99% of helium content, used in dilution refrigerators for ultra-low temperature physics. It is an isotopically pure rare gas.
Helium-3 Research Gas
Helium-3 research gas is an isotopically separated rare gas used in neutron detection and low-temperature physics. Although helium has a specific subheading, helium-3 is classified under 'other' rare gases because it is an isotope not covered by the standard helium subheading.
Helium for Airship Inflation
Aviation-grade helium for airship inflation is a rare gas in elemental form, used for lift. It falls under tariff item 2804.29.00 as 'other' rare gases, as helium is not separately classified in this subheading.
