HS Code for Cerium carbonate

Cerium carbonate is classified under HS code 2846.10, which specifically encompasses compounds, inorganic or organic, of rare-earth metals, of yttrium or of scandium or of mixtures of these metals, with a specific sub-designation for cerium compounds. As a rare-earth compound, cerium carbonate is grouped here because the Harmonized System (HS) nomenclature prioritizes the chemical nature of rare-earth elements over the general carbonate classification found elsewhere in Chapter 28. This classification applies regardless of whether the compound is chemically defined or not, provided it is a compound of cerium. The material is often used in the manufacturing of glass, ceramics, and as a precursor for cerium oxide catalysts. Under the General Rules of Interpretation (GRI), specifically GRI 1, the heading 2846 is the most specific description for this substance, as it identifies the rare-earth metal component which is the defining characteristic of the product's chemical identity and commercial value.

Products Included

• Cerium(III) carbonate

• Cerous carbonate
• Rare-earth carbonate concentrates where cerium is the predominant metal
• Cerium carbonate powder for industrial polishing applications

Common Misclassification

Cerium carbonate is frequently misclassified under HS code 2836.99, which covers "other carbonates." However, Chapter 28, Note 1 and the specific structure of heading 2846 dictate that compounds of rare-earth metals must be classified in 2846, taking precedence over general carbonate headings. Another common error is using HS code 2846.90, which is reserved for rare-earth compounds other than those of cerium. Importers must ensure that if the compound contains cerium as the primary rare-earth element, 2846.10 is the only correct subheading.

FAQ

What is the HS code for cerium carbonate?

The correct HS code for cerium carbonate is 2846.10, which falls under the category of cerium compounds.

Is cerium carbonate considered a hazardous material for shipping?

While classification for customs (HS code) is 2846.10, shipping regulations depend on the purity and physical form; however, it is generally treated as a non-hazardous chemical unless mixed with other regulated substances.
