Related Products under HTS 2513.10.00
Raw Pumice Stone Lumps
Unprocessed pumice stone extracted from volcanic deposits, used primarily as a natural abrasive in industrial grinding and polishing applications. It falls under HTS 2513.10.00 as crude pumice stone, whether or not heat-treated, distinct from manufactured abrasives. The porous, lightweight nature makes it ideal for tumbling and surface preparation.
Heat-Treated Pumice Gravel
Pumice stone gravel thermally processed to enhance durability for use in concrete aggregates and water filtration systems. Classified under HTS 2513.10.00 as heat-treated pumice stone, retaining its natural abrasive properties. The treatment improves density without altering its fundamental pumice composition.
Volcanic Pumice Powder
Finely ground pumice stone powder from natural volcanic sources, employed as an abrasive in metal polishing and paint additives. HTS 2513.10.00 covers this as pumice stone in powdered form, not further manufactured into grinding wheels. Its high silica content provides effective cutting action.
Lava Pumice Stones for Tumbling
Medium-sized pumice stones specifically sized for rock tumbling and lapidary work, sourced from lava flows. Under HTS 2513.10.00 as natural pumice abrasives, suitable for hobbyist and industrial polishing. The irregular shapes provide multi-directional abrasion.
Industrial Pumice Aggregate
Coarse pumice aggregate for lightweight concrete blocks and precast panels, heat-treated for strength. HTS 2513.10.00 applies to this natural abrasive in aggregate form before mixing. Reduces overall concrete weight while maintaining abrasiveness.
Pumice Filter Media
Granular pumice stone serving as filter media in water treatment and aquariums due to its porous structure. HTS 2513.10.00 for natural pumice, valued for abrasive yet filtering properties. Heat-treated variants resist breakdown.
