HS Code for Zinc carbonate
Zinc carbonate is classified under HS code 2836.99. This code falls under heading 2836, which covers carbonates, peroxocarbonates (percarbonates), and commercial ammonium carbonate. As an inorganic salt consisting of zinc cations and carbonate anions, it is classified based on its chemical composition. Subheading 2836.99 is a residual category for "Other" carbonates that are not specifically named in the preceding subheadings, such as those for lithium, strontium, or sodium. In industrial contexts, "basic zinc carbonate" (a hydroxy carbonate) is also frequently encountered and is classified here as well. The classification follows GRI 1 and GRI 6, ensuring that chemically defined inorganic compounds are grouped by their anionic component. This classification is vital for customs as it separates manufactured chemical salts from natural minerals and ores, which are subject to different trade regulations and duty structures.

Common Misclassification
A common misclassification occurs with heading 2608, which covers zinc ores and concentrates. Natural zinc carbonate, known as smithsonite, is classified in Chapter 26 if it is a raw mineral. However, the synthetic or purified chemical version used in industry must be classified in Chapter 28. Another frequent error is confusing zinc carbonate with zinc oxide (HS code 2817.00). While both are used in similar applications like rubber manufacturing and cosmetics, they are chemically distinct. Zinc oxide is an oxide, whereas zinc carbonate contains the carbonate group (CO3), necessitating its placement in heading 2836. Misidentifying the chemical group can lead to incorrect duty payments and delays in customs clearance.
