Products classified under HTS 2513.20.10.00
Natural Corundum Chunks
Irregular pieces of natural corundum, a crystalline form of aluminum oxide found in mineral deposits like those in India or Greece. Supplied crude without refinement for use in abrasive manufacturing. Falls under HTS 2513.20.1000 as crude natural abrasives in irregular form.
Raw Natural Garnet Pieces
Crude, irregular fragments of almandine garnet mined from alluvial deposits, used primarily as waterjet cutting abrasive feedstock. Not heat-treated or sized, maintaining natural irregular shapes. HTS 2513.20.1000 covers these other natural abrasives in crude form.
Crude Natural Quartz Pebbles
Irregular river-washed quartz pebbles selected for high silica content and hardness as tumbling abrasives. Supplied in crude bulk without crushing or grading. Classified as other natural abrasives under HTS 2513.20.1000 in irregular pieces.
Unprocessed Staurolite Sand Lumps
Crude, irregular lumps of staurolite mineral from Georgia deposits, valued for its angular hardness in paint and abrasive applications. Heat-treated versions exist but this is raw. HTS 2513.20.1000 for crude other natural abrasives.
Raw Olivine Sand Chunks
Irregular pieces of forsterite olivine from Norwegian or North Carolina mines, used as foundry abrasive and slag conditioner. Crude form without sizing. Fits HTS 2513.20.1000 as other natural abrasives.
Crude Natural Magnetite Pieces
Irregular magnetite lumps containing emery-like abrasive properties from iron ore deposits. Used in heavy media separation and abrasives. HTS 2513.20.1000 crude form.
Irregular Garnierite Chunks
Crude garnierite (nickel silicate) pieces with natural abrasive texture from laterite deposits. Used in polishing compounds. Under 2513.20.1000.
Bulk Natural Tripoli Lumps
Crude tripoli (rottenstone) irregular pieces, siliceous sedimentary rock for metal polishing. Natural abrasive under HTS 2513.20.1000.
Unrefined Rottenstone Pieces
Irregular rottenstone fragments for fine abrasion, natural decomposed siliceous limestone.
Crude Green Sandstone Blocks
Irregular green sandstone pieces from Scotland, natural abrasive for sharpening.
Raw Arkansas Stone Lumps
Crude novaculite lumps from Arkansas, premium natural sharpening abrasive.
Irregular Natural Emery Powder Feedstock
Large crude emery pieces destined for powdering, still irregular.
Crude Indian Garnet Ore
Bulk irregular garnet-bearing ore from Rajasthan, abrasive grade.
Natural Abrasive Rock Fragments
Mixed crude fragments of various natural abrasives like corundum-garnet mixes.
Crude Natural Emery
Raw, unprocessed emery consisting primarily of corundum and magnetite, extracted directly from natural deposits. It is supplied in irregular lumps or pieces without any cutting, sizing, or heat treatment beyond what's naturally occurring. Classified under HTS 2513.20.1000 as crude natural abrasive in irregular pieces, suitable for further processing into grinding materials.
