Product classification
HS code for Sodium bicarbonate: 2836.30
Carbonates, sodium hydrogen carbonate (sodium bicarbonate).
Classification of sodium bicarbonate under HS 2836.30
Sodium bicarbonate is classified under HS code 2836.30, which falls within Chapter 28 of the Harmonized System. This chapter is dedicated to inorganic chemicals and separate chemically defined compounds. Heading 2836 specifically covers carbonates, peroxocarbonates, and commercial ammonium carbonate containing ammonium carbamate. Sodium bicarbonate, also known as sodium hydrogen carbonate (NaHCO3), is explicitly identified in subheading 2836.30. For a product to be classified here, it must meet the criteria of a separate chemically defined compound as outlined in Note 1 to Chapter 28. This means the substance must be a single chemical entity, although it may contain certain impurities or be dissolved in water. The classification is straightforward for pure technical, food, or pharmaceutical grades of sodium bicarbonate. However, if the sodium bicarbonate is mixed with other substances to create a preparation, such as a leavening agent for baking, it may be moved to a different chapter entirely. The precision of this classification ensures that the chemical is tracked correctly for industrial, food safety, and environmental regulations across international borders.

Codes often confused with 2836.30
Common mistake. A frequent misclassification occurs between sodium bicarbonate (2836.30) and sodium carbonate (2836.20), also known as soda ash. While chemically related, they are distinct compounds with different industrial applications. Another common error is classifying prepared baking powder under 2836.30. Baking powder is a mixture of sodium bicarbonate and an acidifying agent (like cream of tartar), which places it under HS code 3824.71 or 3824.99 as a prepared binder or chemical product. Additionally, natural sodium carbonate (trona) should be classified under heading 2530 rather than the chemical heading 2836.
Top exporters and importers of HS 283630 (the code used for sodium bicarbonate), 2025
In 2025, the largest exporter of HS 283630 (the code used for sodium bicarbonate) in UN Comtrade data was China, with 19% of world exports; the largest importer in UN Comtrade data was France, with 10% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
