HS-4 · Heading
2845 — Isotopes other than those of heading no. 2844; compounds, inorganic or organic, of such isotopes, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2845 when importing or exporting isotopes like heavy water (deuterium oxide) or enriched lithium-6. For instance, if you're shipping heavy water for nuclear reactors, this is the correct classification.
When deciding between HS-6 284510 for heavy water and HS-6 284530 for lithium enriched in lithium-6, consider the specific application. Heavy water is primarily used in nuclear applications, while enriched lithium is often utilized in batteries and nuclear fusion.
If your product includes isotopes not specifically listed, such as those classified under HS-6 284590, ensure you accurately describe the chemical composition. This line covers isotopes and compounds not defined in the other subheadings, which may require additional documentation.
