Argon-38 Enriched Gas
>- Argon-38 is a stable isotope of argon, enriched for use in geological age dating and as a tracer in scientific studies. As a separate chemical element that is not radioactive, it falls under heading 28.45, which covers isotopes other than those of heading 28.44. The product is presented in gaseous form, typically in sealed cylinders for laboratory use.
Carbon-14 Labeled Urea
>- Carbon-14 labeled urea is an organic compound of the radioactive carbon isotope carbon-14, used in biochemical tracer studies and radiometric dating. Although it is an organic compound, heading 28.45 covers compounds, inorganic or organic, of isotopes other than those of heading 28.44. However, because carbon-14 is a radioactive isotope, it is excluded from heading 28.45 by Note 1(A) to Section VI and must be classified in heading 28.44.
Deuterium Oxide (Heavy Water, D2O)
>- Deuterium oxide, commonly known as heavy water, is a compound of the stable hydrogen isotope deuterium. It is used as a moderator in nuclear reactors and in various scientific and industrial applications. As a compound of an isotope other than those of heading 28.44, it is classified under heading 28.45.
Helium-3 Gas
>- Helium-3 is a rare, stable isotope of helium used in cryogenics, neutron detection, and quantum computing. It is a separate chemical element that is not radioactive, and therefore falls under heading 28.45, which covers isotopes other than those of heading 28.44. The product is supplied as a compressed gas in cylinders.
