HS code for Pumice: 2513.10
Pumice stone, whether or not heat treated.
Classification of pumice under HS 2513.10
Pumice is classified under HS code 2513.10. Chapter 25 of the Harmonized System covers salt, sulfur, earths, and stone, as well as plastering materials, lime, and cement. Heading 2513 specifically includes pumice stone, emery, natural corundum, natural garnet, and other natural abrasives. The classification 2513.10 is designated for pumice stone in its natural state or minimally processed forms, such as crushed or heat-treated. According to Chapter 25 Note 1, products are generally classified here only if they are in the crude state or have been washed, crushed, ground, powdered, or screened. The inclusion of 'heat-treated' in the description for 2513.10 allows for pumice that has undergone thermal processing to remove impurities or moisture without changing its essential mineral character.

Codes often confused with 2513.10
Common mistake. Pumice is often misclassified under HS code 6804 if it has been shaped into bonded grinding wheels or stones. Heading 6804 covers millstones and grinding wheels of natural stone or agglomerated abrasives. Another common error occurs when pumice is packaged for retail sale as a cosmetic item (e.g., for removing calluses), which may lead to classification under 3304 (beauty or make-up preparations). However, if it is simply a shaped piece of natural pumice without added soaps or chemicals, it often remains in Chapter 68. Finally, 'pumice' made of expanded glass or slag is classified in 7016 or 2618, as it is not the natural volcanic stone required for 2513.10.

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).
