HS Code 2836.30 – Carbonates; sodium hydrogen carbonate (sodium bicarbonate)
HS code 2836.30 is the 6-digit subheading for carbonates, sodium hydrogen carbonate (sodium bicarbonate). It is used for baking soda, food grade sodium bicarbonate, technical grade sodium bicarbonate, pharmaceutical grade sodium bicarbonate and feed grade sodium bicarbonate.
What HS 2836.30 covers
Sodium hydrogen carbonate, universally known as sodium bicarbonate or baking soda, is classified under this HS code. This versatile compound is widely traded for its leavening properties in food production, its use as an antacid in pharmaceuticals, and as a mild abrasive and deodorizer in cleaning products. It also plays a role in animal feed, water treatment, and fire extinguishers. Countries with significant food processing industries, pharmaceutical manufacturing, and consumer goods production are primary importers. Exporters often have access to natural trona deposits or advanced chemical synthesis capabilities. Key considerations in trade include purity (food grade vs. technical grade), particle size, and packaging, as it's used in both bulk industrial applications and consumer-packaged goods. Its widespread utility across various sectors ensures consistent global demand, making it a staple in international chemical trade.

Codes often confused with 2836.30
Common mistake. This code is distinct from 283620 (disodium carbonate) due to the "hydrogen" component, which significantly alters its chemical properties and uses. It could also be confused with mixtures in 3824.99 if it's part of a prepared baking mix.
Top exporters and importers of HS code 283630, 2025
In 2025, the largest exporter of HS code 283630 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).
