Mica powder Hs Code

Mica powder harmonized system code

Product Overview Mica powder classified under HS Code 252520 refers to finely ground mica minerals primarily composed of hydrous potassium aluminum silicate. This product is characterized by its uniform particle size distribution, typically ranging from 10 to 100 microns, and exhibits high dielectric strength, chemical inertness, and thermal stability. Processing involves mechanical milling and sieving to achieve consistent granulometry and purity levels exceeding 98% mica content. The HS Code 252520 encompasses various subcategories including natural mica flakes, crushed mica, and powdered mica variants differentiated by particle size and grade. Commercially, mica powder is extensively utilized across food service and processing industries as an anti-caking agent, colorant extender, and in specialty packaging. Additionally, it serves crucial roles in cosmetics, electronics, and paint manufacturing due to its reflective and insulative properties. Its market positioning is anchored on superior chemical stability, non-toxicity, and regulatory compliance, offering importers and exporters a reliable raw material source with well-documented provenance and consistent quality control. HS Code Classification & Trade Specifications The full HS Code 252520 is structured as follows: Chapter 25 – Salt; sulphur; earths and stone; plastering materials, lime and cement; Heading 2525 – Natural steatite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape; Subheading 252520 – Mica, including splittings; mica waste. This classification is assigned based on the mineralogical composition and physical form of the product, conforming to the Harmonized System nomenclature established by the World Customs Organization (WCO). Trade considerations for mica powder include packaging in moisture-resistant, multi-layer kraft paper bags or polypropylene sacks typically weighing 25 to 50 kilograms to prevent hygroscopic degradation. Preservation methods mandate dry, temperature-controlled storage to maintain dielectric properties and prevent contamination. Compliance with international quality standards such as ISO 9001 and REACH regulations is critical. Shipping protocols require appropriate labeling, with adherence to WTO trade facilitation agreements ensuring seamless customs clearance and classification accuracy across global markets.

Mica powder 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.
