HS Code for Curium

Curium is classified under HS code 2844.42. This code is part of Chapter 28, which covers inorganic chemicals and precious metal compounds. Specifically, heading 2844 is reserved for radioactive chemical elements and radioactive isotopes. Curium is a transuranic radioactive element, and the subheading 2844.42 specifically lists isotopes such as Curium-240, 241, 242, 243, and 244, along with their compounds, alloys, and dispersions. The classification is driven by the radioactive nature of the material rather than its chemical form (e.g., whether it is a pure metal or a ceramic mixture). Because curium is produced synthetically in nuclear reactors and is highly regulated, its classification is strictly monitored to ensure compliance with international safety and security standards for nuclear materials.

Common Misclassification

Curium is often confused with other radioactive elements in the same heading. For instance, it might be misclassified under 2844.10 (Natural uranium) or 2844.20 (Enriched uranium or plutonium) if the specific isotope is not identified. It may also be confused with 2844.41, which covers Actinium-225 and Tritium. Another error is attempting to classify curium compounds under general inorganic chemical codes in Chapter 28 (like 2825 for metal oxides); however, Note 1 to Chapter 28 dictates that radioactive elements and isotopes always take precedence and must be classified in heading 2844.

FAQ

What is the HS code for Curium?

The HS code for Curium and its specific isotopes (240 through 244) is 2844.42.

Are all curium isotopes under this code?

No, only the isotopes specifically listed in the 2844.42 subheading are included. Other isotopes or radioactive residues may fall under 2844.43 or 2844.44 depending on their activity and specific nomenclature.
