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.
