Product classification
HS code for Strontium carbonate: 2836.92
Carbonates, strontium carbonate.
Classification of strontium carbonate under HS 2836.92
Strontium carbonate is classified under HS code 2836.92. This classification falls within Chapter 28, which covers inorganic chemicals and precious metal compounds. Heading 2836 is dedicated to carbonates and peroxocarbonates. Strontium carbonate (SrCO3) is a chemically defined compound, and the Harmonized System provides a specific subheading for it. The classification is determined by the chemical identity of the substance rather than its intended use. Whether the strontium carbonate is used in the production of glass for cathode ray tubes, in the manufacturing of permanent magnets, or as a colorant in pyrotechnics, it remains under 2836.92 as long as it is a separate chemically defined compound. The purity of the product does not generally change the heading, provided no additives have been included that would transform it into a chemical preparation or a product of another heading.

Codes often confused with 2836.92
Common mistake. A common misclassification occurs with HS code 2530.90, which covers natural strontium carbonate (strontianite). If the product is a raw, naturally occurring mineral that has only been washed or crushed, it belongs in Chapter 25. HS code 2836.92 is strictly for the chemically processed or refined compound. It is also sometimes confused with barium carbonate (2836.60) due to their similar industrial uses in the glass and ceramics industries, but the chemical base (strontium vs. barium) dictates the specific subheading.
Top exporters and importers of HS 283692 (the code used for strontium carbonate), 2025
In 2025, the largest exporter of HS 283692 (the code used for strontium carbonate) in UN Comtrade data was China, with 51% of world exports; the largest importer in UN Comtrade data was China, with 26% 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).
