Zeolite|HS Code

Zeolite harmonized system code

Product Overview Zeolite, which falls under the Harmonized System (HS) Code 2530, is a naturally occurring mineral with a porous structure, typically derived from volcanic rock and ash layers. It exhibits a spectrum of physical specifications, including varying crystal structures, pore sizes, and ion-exchange capacities, with quality attributes such as high thermal stability and strong adsorption properties. Within the HS Code 2530, Zeolite is further categorized based on its specific type and processing level, such as natural zeolites and those chemically treated for specialized uses. Commercially, zeolites are extensively used in a range of industries, including agriculture for soil amendment, water treatment for ion exchange, petrochemical for catalysis, and construction for lightweight materials. Zeolite's value proposition lies in its unique combination of porous structure, ion-exchange capacity, and thermal stability, offering competitive advantages of efficiency, environmental friendliness, and versatility in various applications. HS Code Classification & Trade Specifications Zeolite is classified under the full 6-digit HS Code of 2530.10, where Chapter 25 represents mineral products, Heading 30 pertains to natural or artificial mineral products not elsewhere specified, and Subheading 10 refers specifically to natural zeolites. This classification is based on the product's nature as a mineral product and its distinct characteristics. In terms of trade, zeolites are commonly packaged in bulk bags or containers, given their granular or powdered form. They are usually preserved in a dry environment to maintain their adsorption capacity. Shipping requirements typically involve proper sealing and handling to prevent moisture absorption and dust emission. Quality standards for zeolites, as per international trade norms, focus on parameters like purity, particle size, and ion-exchange capacity, ensuring they meet the specific requirements of different industry applications. This description adheres to World Trade Organization and customs documentation standards, facilitating smooth international trade operations.

Zeolite 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.
