Code 2845 90 · Heading 2845

Other non-radioactive isotopes and their compounds, including undefined mixtures, excluding specified isotopes and compounds

This code covers non-radioactive isotopes and inorganic or organic compounds of isotopes, including products that are not chemically defined. It excludes heavy water, boron enriched in boron-10, lithium enriched in lithium-6, helium-3, and compounds of these, while the children distinguish deuterium products from other isotopes.

For example

Non-radioactive carbon-13 isotope
Non-radioactive oxygen-18 isotope
