Last updated: July 2026 dataPumice stone — a highly vesicular volcanic glass — is traded in two commercial forms under HTS heading 2513: crude or crushed pumice (2513100010), used in construction aggregates, horticulture, and abrasive blasting, and processed pumice (2513100080), which has been shaped, graded, or otherwise refined for personal care, cosmetic, or precision abrasive applications. The distinction between crude/crushed and further-processed forms is the key classification boundary, and importers of cosmetic-grade pumice blocks or shaped pieces should ensure their product is correctly assigned to the processed line.

17 shipments/mo
Crude or crushed pumice (2513100010) covers material in its natural extracted state or broken into irregular pieces, including sized aggregate. Pumice that has been shaped into blocks, sticks, or other defined forms — such as cosmetic foot-care stones or precision abrasive tools — is classified as 'except crude or crushed' under 2513100080, reflecting the additional manufacturing step.
Crude and crushed pumice serves the construction industry as a lightweight aggregate, the horticultural sector as a soil amendment and drainage medium, and the industrial sector as an abrasive blasting media. Processed pumice blocks and sticks are used in personal care (foot exfoliation), textile stonewashing (denim finishing), and specialty surface preparation applications.
