HS Code 2834.10 – Nitrites
HS code 2834.10 is the 6-digit subheading for nitrites. It is used for sodium nitrite, potassium nitrite, calcium nitrite, amyl nitrite and isobutyl nitrite.
What HS 2834.10 covers
This HS code covers nitrites, which are salts of nitrous acid, with sodium nitrite and potassium nitrite being the most common examples. These compounds possess diverse industrial applications, notably in the food industry as crucial preservatives, especially for cured meats, where they inhibit bacterial growth and enhance color. In the chemical industry, they are vital for the synthesis of organic compounds, including dyes and pharmaceuticals, and in metallurgy, they serve as effective corrosion inhibitors. Major food processing companies, chemical manufacturers, and pharmaceutical firms are key importers, while large chemical producers are the main exporters. Trade in nitrites necessitates strict adherence to food safety regulations and chemical handling protocols due to their toxicity in high concentrations. The 'CBAM' tag indicates potential carbon border adjustment mechanism implications, suggesting that their production processes may be energy-intensive.

Codes often confused with 2834.10
Common mistake. Nitrites (2834.10) are distinct from nitrates (2834.2x) due to their different chemical structures and applications, though both contain nitrogen and oxygen.
Top exporters and importers of HS code 283410, 2025
In 2025, the largest exporter of HS code 283410 in UN Comtrade data was China, with 36% of world exports; the largest importer in UN Comtrade data was the United States, with 9.9% 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).
