HS Code for Heavy water

Heavy water, scientifically known as deuterium oxide (D2O), is classified under HS code 2845.10. This classification falls within Chapter 28, which covers inorganic chemicals and precious metal compounds. Specifically, heading 2845 is reserved for isotopes other than those of heading 2844 and their compounds. Heavy water is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium. Because it is an isotopic compound rather than a standard chemical or a radioactive isotope (which would fall under 2844), it is explicitly placed in 2845.10. This substance is primarily used in certain types of nuclear reactors as a neutron moderator and in scientific research for NMR spectroscopy. The classification is straightforward because deuterium oxide is the only product mentioned in this specific subheading, reflecting its unique physical properties and strategic importance.

Common Misclassification

Heavy water is occasionally misclassified under 2201.90 (ordinary water) by those unfamiliar with its chemical properties. However, because it is an isotopic compound, Chapter 28 takes precedence over Chapter 22. It may also be confused with 2844.40 if the user incorrectly assumes it is radioactive; while used in nuclear reactors, pure heavy water itself is not a radioactive isotope and thus belongs in 2845.10.

FAQ

What is the HS code for heavy water?

The specific HS code for heavy water (deuterium oxide) is 2845.10.

Is heavy water classified as a hazardous chemical?

While HS classification 2845.10 identifies the substance, its status as a hazardous or controlled material depends on national regulations and its concentration, often requiring export licenses due to its use in nuclear applications.
