Product classification
HS code for Baking soda: 2836.30
Carbonates, sodium hydrogen carbonate (sodium bicarbonate).
Classification of baking soda under HS 2836.30
Baking soda, chemically known as sodium hydrogen carbonate or sodium bicarbonate, is classified under HS code 2836.30. This classification falls within Chapter 28, which is dedicated to inorganic chemicals and precious metal compounds. As a separate chemically defined compound with the formula NaHCO3, it meets the criteria for heading 2836, which covers carbonates. The classification is determined by GRI 1, as the subheading 2836.30 explicitly names sodium hydrogen carbonate. Even when the product is packaged for retail sale for culinary purposes, it remains in Chapter 28 as long as it is pure sodium bicarbonate without added leavening agents or other ingredients that would transform it into a prepared food additive.

Codes often confused with 2836.30
Common mistake. The most frequent misclassification occurs with baking powder, which is classified under HS code 2102.30. Unlike baking soda, baking powder is a mixture of sodium bicarbonate and an acidifying agent (like cream of tartar) and a starch. Importers often confuse the two due to their similar names and uses. Additionally, sodium carbonate (washing soda) is classified under 2836.20 and should not be confused with the hydrogen carbonate version in 2836.30.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
