Salt harmonized system code

Product Overview Salt classified under HTS 2501.00 is chemically defined as sodium chloride (NaCl), including denatured salt, presented as a solid crystalline mineral product for edible, industrial or technical use. Key characteristics include crystalline morphology (granules, flakes, rock), granulometry (typical particle size ranges 0.1–6.0 mm), NaCl assay (commonly 94–99.9% depending on grade), moisture content (food/refined ≤2% typical), insolubles (expressed as ppm or %; food-grade <0.1% typical), and permissible additives (iodization levels, anti-caking agents). Processing levels span rock mining, solar evaporation, vacuum/evaporated refining and further purification (ion-exchange, recrystallization). Within HTS 2501.00 commercial subcategories commonly referenced by traders and brokers include: solar/sea salt, vacuum/evaporated salt (refined), rock salt, denatured salt (for non-food uses), iodized/table salt, and chemical-grade salt for alkali production. Primary commercial applications cover human and animal food seasoning and preservation, road de-icing, chlor-alkali feedstock, water treatment, textile/leather processing and various industrial manufacturing processes requiring defined NaCl purity and granulometry. HTS Code Classification & Trade Specifications Full 6-digit HTS structure: Chapter 25 (Salt; sulphur; earths and stone; plastering materials, lime and cement) — Heading 2501 (sodium chloride (including denatured salt) and pure sodium chloride) — Subheading 250100 (sodium chloride). Classification rationale: commodity classification rests on dominant chemical composition (predominantly NaCl), physical state (solid crystalline salt), and whether the salt is denatured or chemically modified; further 8–10 digit national subdivisions distinguish food-grade/iodized, bulk vs. packaged and other treatment-specific variants for duty assessment. Trade considerations: standard commercial packaging includes 25 kg and 50 lb paper/polypropylene bags, 500–1,000 kg FIBCs (jumbo bags), and loose bulk in lined containers or dry-bulk vessels; moisture control, liners, desiccants and anti-caking agents are specified to preserve quality. Shipping/handling: generally non-hazardous but segregated per-grade requirements; documentation for customs typically requires CoA, specification sheet (NaCl %, moisture, insolubles), country of origin and applicable food/chemical standards (USP, FCC, Codex Alimentarius, AWWA) to support tariff classification and duty calculation.

Salt Chapter Note

1.- Except where their context or Note 4 to this Chapter otherwise requires, the headings of this Chapter cover only products which are in the crude state or which have been washed (even with chemical substances eliminating the impurities without changing the structure of the product), crushed, ground, powdered, levigated, sifted, screened, concentrated by flotation, magnetic separation or other mechanical or physical processes (except crystallisation), but not products which have been roasted, calcined, obtained by mixing or subjected to processing beyond that mentioned in each heading. The products of this Chapter may contain an added anti-dusting agent, provided that such addition does not render the product particularly suitable for specific use rather than for general use. 2.- This Chapter does not cover : (a) Sublimed sulphur, precipitated sulphur or colloidal sulphur (heading 28.02); (b) Earth colours containing 70 % or more by weight of combined iron evaluated as Fe2O3 (heading 28.21); (c) Medicaments or other products of Chapter 30; (d) Perfumery, cosmetic or toilet preparations (Chapter 33); (e) Dolomite ramming mix (heading 38.16); (f) Setts, curbstones or flagstones (heading 68.01); mosaic cubes or the like (heading 68.02); roofing, facing or damp course slates (heading 68.03); (g) Precious or semi-precious stones (heading 71.02 or 71.03); (h) Cultured crystals (other than optical elements) weighing not less than 2.5 g each, of sodium chloride or of magnesium oxide, of heading 38.24; optical elements of sodium chloride or of magnesium oxide (heading 90.01); (ij) Billiard chalks (heading 95.04); or (k) Writing or drawing chalks or tailors' chalks (heading 96.09). 3.- Any products classifiable in heading 25.17 and any other heading of the Chapter are to be classified in heading 25.17. 4.- Heading 25.30 applies, inter alia, to : vermiculite, perlite and chlorites, unexpanded; earth colours, whether or not calcined or mixed together; natural micaceous iron oxides; meerschaum (whether or not in polished pieces); amber; agglomerated meerschaum and agglomerated amber, in plates, rods, sticks or similar forms, not worked after moulding; jet; strontianite (whether or not calcined), other than strontium oxide; broken pieces of pottery, brick or concrete.
