Last updated: April 2026 dataNitrates not elsewhere specified under SITC 52359 capture a range of inorganic nitrate salts — such as calcium nitrate, magnesium nitrate, and barium nitrate — that fall outside the dedicated potassium nitrate heading. These compounds serve varied industrial roles including fertilizer blending, explosives manufacturing, and specialty chemical synthesis. Classification into this residual heading requires careful review to confirm the substance does not belong to a more specific SITC or HTS provision, making precise chemical identification in shipping documentation essential.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
SITC 52359 is a residual heading covering inorganic nitrate salts not assigned to a more specific code — most notably excluding potassium nitrate (52352) and ammonium nitrate (classified under fertilizers). Importers must confirm the chemical identity and purity of the salt to determine whether a dedicated heading applies before defaulting to the NES category.
Certain nitrate compounds, particularly those sourced from specific countries, may be subject to antidumping or countervailing duty orders. Importers should check the US International Trade Commission and Commerce Department order lists against the specific compound and country of origin before entry.
