HS Code for Pumice stone

Pumice stone is classified under HS code 2513.10. Chapter 25 covers salt, sulfur, earths and stone, plastering materials, lime, and cement. Pumice is a volcanic rock consisting of highly vesicular rough-textured volcanic glass. The classification applies to the stone in its natural state or even if it has been heat-treated, provided it has not been further worked into a specific tool or cosmetic product. The Harmonized System groups natural mineral substances in Chapter 25 based on their geological origin and minimal processing. Even if the pumice is crushed or ground into powder, it remains within this heading as long as it is not mixed with other substances. The key to this classification is the raw or minimally processed nature of the mineral. Once the stone is shaped into a specific abrasive tool or packaged for retail sale as a beauty product with added ingredients, the classification shifts to other chapters.

Common Misclassification

Pumice stone is often misclassified under HS code 6804, which covers millstones, grindstones, and grinding wheels. However, 6804 is intended for stones that have been worked into specific shapes or bonded with abrasives for mechanical use. If the pumice is simply a natural stone used for abrasive purposes without being shaped into a tool, it stays in 2513.10. Another common misclassification is HS code 3304, which covers beauty or make-up preparations. While pumice is used for pedicures, it only moves to Chapter 33 if it is prepared with soaps, oils, or other chemicals, or if it is put up in specialized retail packaging for cosmetic use.
