Products classified under HTS 2513.10.00.80
Crushed Pumice Stone for Abrasive Cleaning
Crushed pumice stone is a naturally occurring volcanic rock used as an abrasive for cleaning surfaces like pots, ovens, and industrial equipment. It falls under HTS 2513.10.0080 as 'other' pumice stone that is not solely for grinding or polishing millstones, heat-treated or not. The irregular granules provide effective scrubbing without scratching.
Pumice Powder for Metal Polishing
Fine pumice powder derived from natural pumice stone, used as a mild abrasive for polishing metals, jewelry, and lapidary work. Classified under HTS 2513.10.0080 as 'other' pumice, distinct from millstone-specific uses. Its porous structure allows gentle material removal without excessive scratching.
Tumbled Pumice Pebbles for Stone Washing
Smooth, tumbled pumice pebbles used in textile stone-washing processes to create distressed denim effects. Falls under HTS 2513.10.0080 as 'other' pumice stone, a natural abrasive not limited to millstones. The rounded shape prevents fabric damage while providing abrasion.
Heat-Treated Pumice Granules for Water Filtration
Heat-treated pumice granules optimized for porosity in water filtration systems and aquariums. Classified in HTS 2513.10.0080 as 'other' pumice stone, permissible even if heat-treated per heading terms. Enhances biological filtration through natural porous structure.
Natural Pumice Blocks for Hand Scrubbing
Solid natural pumice blocks used for personal care like removing calluses and dead skin on feet. HTS 2513.10.0080 covers this 'other' pumice stone as a natural abrasive. Lightweight and porous for effective yet gentle exfoliation.
Pumice Grit for Sandblasting Media
Coarse pumice grit sized for low-pressure sandblasting to clean masonry and delicate surfaces. Falls under HTS 2513.10.0080 as 'other' natural pumice abrasive. Provides gentler blasting than quartz or garnet.
Volcanic Pumice for Horticultural Soil Amendment
Graded volcanic pumice used to improve soil aeration and drainage in horticulture and hydroponics. Classified HTS 2513.10.0080 as pumice stone with abrasive properties, though used agriculturally. Natural porosity retains moisture while preventing compaction.
Fine Pumice Flour for Paint Extender
Ultrafine pumice flour used as inert extender pigment in paints and coatings. HTS 2513.10.0080 includes this 'other' pumice as natural abrasive material. Provides matting effect and abrasion resistance.
Pumice Stones for Pool Filter Media
Lightweight pumice stones sized for swimming pool and spa filtration systems. Classified under HTS 2513.10.0080 as other pumice stone natural abrasives. High surface area traps particulates effectively.
Scoria Pumice Mix for Abrasive Blasting
Blended scoria and pumice mix for economical abrasive blasting of ship hulls and bridges. HTS 2513.10.0080 covers pumice component as principal natural abrasive material. Lower density reduces dust compared to slag abrasives.
Pumice Lapidary Grit for Gemstone Tumbling
Graded pumice grit for rotary tumbling rough gemstones and cabochons. Falls under HTS 2513.10.0080 as other natural pumice abrasives. Provides pre-polish stage before finer silicon carbide.
Lightweight Pumice Aggregate for Concrete
Crushed pumice aggregate producing lightweight structural concrete with good insulation. Classified HTS 2513.10.0080 as pumice stone natural abrasive material sized for concrete mix. Reduces dead load while maintaining strength.
Pumice Buffing Compound Base
Pumice powder base for formulating buffing compounds used on wood, plastic, and composites. HTS 2513.10.0080 as other pumice stone providing natural abrasive cutting action. Mixes easily with waxes and oils.
Pumice for Foundry Core Sand Additive
Fine pumice added to foundry core sands improving permeability and reducing defects. Classified under HTS 2513.10.0080 as pumice stone natural abrasive. Enhances collapsibility for easier shakeout.
Natural Pumice for Soap Manufacturing
Granular pumice incorporated into heavy-duty hand soaps for mechanic and industrial cleaning. HTS 2513.10.0080 covers the pumice stone component as natural abrasive ingredient. Suspends effectively in soap base.
