Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing radioactive isotopes
Any radioactive content prioritizes classification in 2844 over rare gas headings.
If not isotopically pure
Xenon gas below 99% isotopic purity falls under other rare gases 2804.40.0000.
If imported as laboratory reagent mixture
Diagnostic or lab reagent preparations classify in 3822, not pure elements.

Import Tips & Compliance
• Require supplier certificate of analysis confirming Xe-129 enrichment >99% to justify 2804.29.0030 classification
• Comply with EPA import notifications for high-purity gases used in research applications
• Package in certified high-pressure cylinders; declare as 'research gas' to avoid general chemical tariffs
