Last updated: July 2026 dataA lightweight volcanic mineral prized for its abrasive and pozzolanic properties, pumice stone serves the construction, personal care, and horticulture industries as a natural exfoliant, lightweight aggregate, and soil amendment. Its low bulk density and high porosity distinguish it from other abrasive minerals, making grade and particle size the primary commercial specifications. Importers should confirm whether material is raw crushed pumice or processed to a specific mesh size, as classification can hinge on the degree of processing.

Raw or roughly crushed pumice typically falls under mineral headings for crude non-metallic minerals, while pumice that has been ground, screened, or otherwise processed to a specific particle size may shift classification toward processed abrasives. Importers should verify the processing state with a licensed customs broker before entry.
Construction (as a lightweight concrete aggregate and pozzolanic cement additive), personal care (exfoliating products), and horticulture (soil aeration media) are the primary demand sectors. Particle size and purity specifications differ significantly across these applications, so suppliers typically offer grade-specific product lines.
