HS Code for Cerium oxide

Cerium oxide is classified under HS code 2846.10, which specifically covers cerium compounds. As part of Chapter 28 (Inorganic chemicals), this classification is reserved for chemically defined compounds. Cerium is a rare-earth metal, and its oxides (such as CeO2, also known as ceric oxide or cerium dioxide) are vital in various industrial applications, including glass polishing, catalysis, and self-cleaning ovens. The classification remains in 2846.10 regardless of the purity level, provided it is not a "prepared" mixture for a specific functional use that would classify it elsewhere. For example, a polishing powder consisting of cerium oxide mixed with other abrasives and binders might be classified in Chapter 38. Customs authorities require technical documentation to confirm the chemical composition as a cerium-based compound to distinguish it from mixed rare-earth oxides (which fall under 2846.90). The classification is driven by the chemical identity of the rare-earth element present in the compound.

Products Included

• Cerium dioxide (CeO2)
• Cerous oxide (Ce2O3)
• High-purity cerium oxide powder
• Cerium hydroxide

Common Misclassification

Cerium oxide is often misclassified under HS code 2530.90 (natural rare-earth minerals) if the product is an unrefined ore. It can also be confused with HS code 3824.99 if it is part of a complex chemical mixture. Furthermore, mixtures of different rare-earth oxides are classified under 2846.90 rather than 2846.10.

FAQ

What is the HS code for cerium oxide?

The HS code for cerium oxide and other cerium compounds is 2846.10.

Is cerium oxide classified as a radioactive chemical?

No, cerium is a rare-earth metal but is not typically classified as radioactive under Chapter 28 unless it contains specific isotopes defined in heading 2844.
