Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lower purity grades
Research-grade (99.99%) helium may fall under 'other' if not meeting strict chemically defined specs.
If containing phosphides or other additives
Heading 2853 covers other inorganic compounds like phosphide-doped helium exceeding 15% phosphorus.
If sold as prepared lab reagent kit
Retail-packed helium with indicators becomes a chemical preparation outside Chapter 28 elements.

Import Tips & Compliance
• Include NIST-traceable purity certificates; medical-grade requires GMP compliance documentation
• Cryogenic containers need UN certification; declare as 'helium, refrigerated liquid' if applicable
