HS Code 2834.29 – Nitrates; of other than potassium
HS code 2834.29 is the 6-digit subheading for nitrates, of other than potassium. It is used for sodium nitrate, calcium nitrate, ammonium nitrate (when not classified as fertilizer), magnesium nitrate and barium nitrate.
What HS 2834.29 covers
This broad HS code covers nitrates other than potassium nitrate, encompassing a wide array of compounds such as sodium nitrate, calcium nitrate, and various metallic nitrates. These chemicals are extensively utilized in agriculture as fertilizers, providing essential nutrients for crop development. In the chemical industry, they are crucial for synthesizing other compounds, and they also find applications in explosives manufacturing, specialized glass production, and wastewater treatment. Importers range from large agricultural cooperatives and chemical manufacturers to mining companies. Exporters are typically global chemical giants. The 'CBAM' tag indicates potential carbon border adjustment mechanism implications, suggesting energy-intensive production processes. Trade considerations include specific chemical composition, purity levels, and strict regulatory compliance, especially for compounds like ammonium nitrate, which have dual-use concerns. This category's diverse applications ensure its significant presence in global trade.

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).
