HS Code for Helium-3

Helium-3 is classified under HS code 2845.40. This classification is distinct from standard helium because Helium-3 is a specific isotope. Under the Harmonized System, Chapter 28, Note 6 defines isotopes for the purposes of heading 2845. This heading includes isotopes other than those of heading 28.44, which is reserved for radioactive isotopes and their compounds. Since Helium-3 is a stable, non-radioactive isotope, it is excluded from 28.44 and must be classified under 2845. The subheading 2845.40 specifically identifies Helium-3. This classification takes precedence over heading 2804 (where standard helium is found) because of the specific nature of the product as an isotope. GIR 1 and 6 are applied here to ensure that the most specific description is used. Helium-3 is a rare isotope of helium with a nucleus containing two protons and one neutron, making it highly valuable for specialized applications such as neutron detection, cryogenics, and quantum computing research. Even when mixed with other gases, if the Helium-3 component is the primary isotope of interest for its isotopic properties, this code is typically applied by customs authorities globally.

Products Included

• Compounds containing the Helium-3 isotope

Common Misclassification

The most common misclassification for Helium-3 is HS code 2804.29, which is the code for standard, naturally occurring helium. While Helium-3 is a form of helium, the HS system prioritizes the classification of isotopes under heading 2845. Another potential error involves HS code 2844.40, which covers radioactive isotopes. Because Helium-3 is stable and not radioactive, it must remain in 2845.40. Importers must ensure that the isotopic purity is documented to justify the use of 2845.40 over the general helium code.

FAQ

What is the HS code for Helium-3?

The HS code for Helium-3 is 2845.40, which is the specific subheading for this stable isotope.

Why is Helium-3 not classified with regular helium?

The Harmonized System contains a specific heading (2845) for isotopes. Because Helium-3 is an isotope, it is classified based on its atomic structure rather than as a general rare gas under 2804.
