Last updated: August 2026 dataCalcium nitrate—widely used as a nitrogen-calcium fertilizer and concrete accelerator—is the commercially dominant product in this residual nitrates heading, alongside bismuth, strontium, and other specialty nitrates. Norway leads US imports, reflecting that country's large-scale calcium nitrate production capacity, with Spain and China also significant sources. The heading spans five 10-digit lines including bismuth nitrates (2834290500), calcium nitrates (2834291000), and strontium nitrates (2834292000), so precise chemical identification is essential for correct line selection.

Pure calcium nitrate is classified under 2834291000. Calcium-ammonium nitrate blends, however, may fall under a different heading depending on their composition and whether they are formulated as fertilizers—potentially in Chapter 31. A licensed customs broker should be consulted to determine the correct classification based on the product's exact chemical specification.
Strontium nitrate (2834292000) is enumerated separately because of its specific use as a red-flame colorant in pyrotechnics and signal flares, distinguishing it from fertilizer or industrial nitrates. Importers of strontium nitrate should also be aware of ATF and state-level regulations governing oxidizers used in pyrotechnic applications.
