Rough granite blocks Hs Code

Rough granite blocks harmonized system code

Product Overview Rough granite blocks classified under HS Code 251611 are natural stone materials extracted directly from quarries with minimal processing. These blocks are typically rectangular or irregular in shape, measuring from 0.5 to 2 cubic meters in volume, and retain their raw, uncut surface texture without polishing or finishing. Key physical characteristics include high compressive strength (typically 100-250 MPa), low porosity, and durability, making them suitable for further fabrication. The HS Code 251611 encompasses rough blocks and slabs of granite, distinguishing them from processed granite products such as cut-to-size blocks or polished slabs. These blocks serve as foundational raw materials predominantly used in construction, architectural applications, and monument production. Their robustness and natural aesthetics position them competitively in international markets as essential inputs for dimension stone processing industries. Due to their dense structure and resistance to weathering, rough granite blocks are favored for heavy-duty applications including paving, cladding, and structural supports, offering long-term value to importers and manufacturers. HS Code Classification & Trade Specifications The HS Code 251611 falls under Chapter 25 (Salt; Sulfur; Earths and Stone), Heading 2516 (Granite, porphyry, basalt, sandstone and other monumental or building stone), with Subheading 251611 specifically identifying rough blocks and slabs of granite. This classification is based on the product’s physical state (rough, unprocessed) and material composition (natural granite). For trade compliance, these blocks are typically shipped in bulk or on pallets, secured with steel bands and protective strapping to prevent damage during transit. Preservation methods focus on minimizing moisture exposure and mechanical shock, often utilizing waterproof covers or shrink wraps. Quality standards for customs documentation require detailed measurement of block dimensions, weight (ranging from 500 kg to several tonnes per block), and certification of mineral composition to ensure conformity with international standards such as ISO 9001 and ASTM C615. Accurate HS classification facilitates tariff determination, import/export licensing, and adherence to WTO trade agreements, ensuring smooth customs clearance and regulatory compliance in global trade operations.

Rough granite blocks 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.
