HS-4 · Heading
2836 — Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2836 when importing or exporting carbonates like sodium bicarbonate or calcium carbonate. For example, if you're shipping bags of sodium hydrogen carbonate for baking purposes, this heading applies directly to your product.
Deciding between the subheadings can be tricky. If your product is disodium carbonate, classify it under HS-6 283620. However, if it’s sodium hydrogen carbonate, you’ll need HS-6 283630. Pay attention to the chemical composition to avoid misclassification.
For potassium carbonate, use HS-6 283640, while calcium carbonate falls under HS-6 283650. If your product contains barium carbonate, it should be classified as HS-6 283660. Each subheading specifies the exact type of carbonate, so ensure you choose the correct one based on your product's chemical makeup.
