HS Code 2513.10 – Pumice stone, whether or not heat treated
HS code 2513.10 is the 6-digit subheading for pumice stone, whether or not heat treated. It is used for pumice lumps, pumice aggregate, pumice powder, horticultural pumice and pumice abrasive.
What HS 2513.10 covers
This HS code covers pumice stone, a lightweight, porous volcanic rock, which may or may not have undergone heat treatment. Pumice is formed during explosive volcanic eruptions, resulting in a highly vesicular texture. Its unique properties make it valuable across a range of industries. It's widely used as an abrasive in polishing compounds, stonewashed denim, and personal care products; as a lightweight aggregate in concrete and horticulture; and as a filter medium. Countries with active construction, textile, or horticultural industries are significant importers. Exporters are typically nations located in volcanically active regions, such as Turkey, Greece, Italy, and the USA. Key factors in trade include particle size, density, hardness, and chemical inertness, which determine its suitability for specific applications. The global demand for pumice is driven by its versatility and natural origin.

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).
