Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If impure or mixed with other gases
Helium below analytical purity or in mixtures falls under the residual 'other' subheading.
If chemically doped for semiconductors
Doped helium in unworked forms like cylinders stays in Chapter 28, but processed discs shift to 3818 mixed preparations.
If classified as hydrocarbon gas mixture
Mislabeling as natural gas mix moves it to Chapter 29 organics, but pure helium remains Chapter 28 rare gas.

Import Tips & Compliance
• Obtain DOT approval for cylinders and include safety data sheets (SDS) detailing purity and pressure ratings
• Verify helium purity exceeds 99.99% to confirm classification as chemically defined rare gas, avoiding reclassification
