Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If radioactive isotopes are present
Radioactive isotopes or their compounds fall under heading 2844 regardless of purity or gas form.
If natural isotopic mixture
Mixtures not isotopically pure (less than 99% single isotope) classify as other rare gases in 2804.29.0010.
If doped for electronic use and cut into wafers/discs
Doped chemical elements in wafer/disc form shift to heading 3818 for semiconductor materials.

Import Tips & Compliance
• Verify isotopic purity certification from supplier exceeding 99% by volume to meet HTS 2804.29.0030 criteria
• Obtain Material Safety Data Sheets (MSDS) and ensure compliance with DOT regulations for compressed gas transport
• Avoid misclassification as standard helium (2804.29.0010); declare isotopic composition accurately to prevent audits
