Product classification
HS code for Stone powder: 2517.49
Stones, of heading no. 2515 or 2516 (excluding marble), in granules, chippings and powder, whether or not heat-treated.
Classification of stone powder under HS 2517.49
Stone powder is classified under HS code 2517.49 because it consists of granules, chippings, or powder derived from stones listed in headings 2515 or 2516, such as granite, porphyry, basalt, or sandstone. This classification applies regardless of whether the material has been heat-treated. The Harmonized System organizes mineral products in Chapter 25 based on their level of processing and mineralogical composition. Since stone powder is a primary product of crushing and grinding natural stone (other than marble, which has its own specific subheading), it falls under this specific category. The classification remains consistent for industrial applications where the stone is reduced to a fine particulate form for use in construction, manufacturing, or landscaping. The technical definition requires the material to be in a crushed state, distinguishing it from blocks or slabs of stone that have not yet undergone the pulverization process.

Codes often confused with 2517.49
Common mistake. A frequent error involves confusing 2517.49 with 2517.41. While both cover stone powder and granules, 2517.41 is reserved exclusively for marble. If the powder is derived from granite, basalt, or sandstone, it must be declared under 2517.49. Additionally, silica sands are often incorrectly placed here but should be classified under 2505.10. Another point of confusion is 2515.11, which covers crude or roughly trimmed marble, whereas 2517.49 requires the stone to be in a crushed or powdered state. Importers must verify the geological origin of the stone to avoid these common errors.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
