Products classified under HTS 3102.50.00.00
Industrial Grade Sodium Nitrate
Pure sodium nitrate (NaNO3) crystals used primarily as an oxidizing agent in industrial applications such as glass manufacturing and pyrotechnics. Classified under HTS 3102.50.00.00 as it matches the chapter note description of sodium nitrate, whether or not pure, and is not packaged for retail sale under heading 3105.
Agricultural Sodium Nitrate Fertilizer
Granular sodium nitrate formulated for direct soil application to provide nitrogen and sodium nutrients to crops like beets and leafy greens. Falls under HTS 3102.50.00.00 per heading 3102 note (a)(i) for sodium nitrate used in fertilizers, not in retail packages of 3105.
Technical Grade Sodium Nitrate 99% Pure
High-purity (99%) sodium nitrate powder for use in explosives manufacturing and metal processing. HTS 3102.50.00.00 applies as 'sodium nitrate, whether or not pure' under chapter note 3102(a)(i), excluding only retail-packaged forms.
Chile Saltpeter Sodium Nitrate
Natural sodium nitrate extracted from caliche deposits, historically known as Chile saltpeter, used in fertilizers and food preservation. Classified in HTS 3102.50.00.00 as sodium nitrate per note (a)(i), provided not in 3105 retail forms.
Sodium Nitrate Flux for Glass Production
Coarse sodium nitrate used as a fluxing agent in glass melting furnaces to lower melting points. HTS 3102.50.00.00 per chapter note allowing 'whether or not pure' sodium nitrate for non-retail fertilizer or chemical uses.
Food Grade Sodium Nitrate E251
Pharmaceutical-grade sodium nitrate (E251) used as a curing agent in meat products to prevent botulism. Still under HTS 3102.50.00.00 as 'sodium nitrate, whether or not pure,' not excluded by chapter notes unless retail-packaged.
Bulk Sodium Nitrate for Pyrotechnics
Prilled sodium nitrate serving as primary oxidizer in fireworks and signal flare production. HTS 3102.50.00.00 classification holds for pure sodium nitrate in bulk industrial form, per chapter note (a)(i).
