Dolomite|HS Code

Dolomite harmonized system code

Product Overview Dolomite, classified under the Harmonized System (HS) Code 2518, refers to a specific type of sedimentary carbonate rock predominantly composed of the mineral dolomite (calcium magnesium carbonate). It exhibits a white to grey hue, possesses a vitreous to pearly luster, and typically features a granular to massive structure. Within HS Code 2518, Dolomite is subdivided into several categories including calcined, agglomerated, and those not calcined or agglomerated. The calcination process, which involves heating to high temperatures, results in dolomite with enhanced hardness and density - ideal for specific applications such as construction and manufacturing. Commercially, dolomite is frequently used in the production of cement and ceramics, as a component in the steel industry, and in environmental clean-ups. Its versatility, abundance, and cost-effectiveness position dolomite as a valuable commodity in both domestic and international markets. HS Code Classification & Trade Specifications Dolomite falls under Chapter 25 (Salt; sulphur; earths and stone; plastering materials, lime and cement) of the Harmonized Commodity Description and Coding System. The 6-digit HS Code 2518 breaks down to Chapter 25 (mineral products), Heading 18 (dolomite; dolomite roughly trimmed or merely cut, into blocks or slabs of a rectangular shape; dolomite ramming mix). The classification of dolomite under this code is due to its mineralogical composition and characteristics. Dolomite is commonly traded in bulk or packaged in bags, with appropriate measures taken to preserve its quality during transit such as moisture-proof packaging to prevent water absorption. The quality of dolomite traded internationally is often measured by purity levels, size, and hardness, with specific requirements varying based on the intended application. Adherence to these quality standards and trade regulations ensures the facilitation of seamless trading operations and customs clearance.

Dolomite 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.
