Products classified under Tariff item 2513.20.00
Almandine Garnet Sandblasting Media
Almandine garnet sandblasting media is washed and sized almandine garnet sand from Indian river deposits, optimized for paint removal. The garnet is a natural abrasive, and despite washing and sizing, it remains within the scope of tariff item 2513.20.00, as these processes are permitted by Chapter 25 Note 1.
Bulk Natural Tripoli Lumps
Bulk natural tripoli lumps, also known as rottenstone, are irregular pieces of siliceous sedimentary rock used for metal polishing. They are in a crude state, not subjected to processing beyond washing, crushing, or grinding, and qualify as natural abrasives under tariff item 2513.20.00.
Crude Indian Garnet Ore
Crude Indian garnet ore consists of irregular garnet-bearing rock fragments from Rajasthan, mined for abrasive applications. The ore is in a crude state, not heat-treated or processed beyond extraction, and falls under tariff item 2513.20.00 as natural garnet.
Crude Natural Emery
Crude natural emery is raw, unprocessed emery composed primarily of corundum and magnetite, extracted directly from natural deposits. Supplied in irregular lumps without cutting, sizing, or heat treatment, it qualifies as a natural abrasive under tariff item 2513.20.00.
Irregular Natural Emery Powder Feedstock
Irregular natural emery powder feedstock consists of large crude emery pieces destined for powdering. These pieces are in a crude state, without heat treatment or mixing, and are classified as natural abrasives under tariff item 2513.20.00.
Natural Corundum Chunks
Natural corundum chunks are irregular pieces of crystalline aluminum oxide from mineral deposits, supplied crude without refinement. These chunks are used in abrasive manufacturing and fall under tariff item 2513.20.00 as natural corundum.
Natural Emery Coarse Grain
Natural emery coarse grain consists of crushed and screened grains from natural emery rock, a corundum-garnet mixture from Naxos deposits. The crushing and screening are permitted mechanical processes under Chapter 25, and the product falls under tariff item 2513.20.00.
Natural Garnet Abrasive Grit
Natural garnet abrasive grit consists of coarse angular grains of natural almandine garnet from alluvial deposits, heat-treated for consistent hardness. Despite heat treatment, the product remains a natural abrasive under tariff item 2513.20.00, as the heading explicitly includes heat-treated natural abrasives.
Natural Olivine Sand Abrasive
Natural olivine sand abrasive is crushed olivine (magnesium-iron silicate) from Norwegian mines, used in foundry cleaning and shipyard blasting. The crushing is a permitted mechanical process, and the product falls under tariff item 2513.20.00 as other natural abrasives.
Natural Wollastonite Abrasive Powder
Natural wollastonite abrasive powder is micronized wollastonite mineral (calcium silicate) from natural deposits, used as a mild abrasive in toothpaste and polishing compounds. The micronization is a mechanical process permitted under Chapter 25, and the product falls under tariff item 2513.20.00.
Picrophyllite Natural Abrasive
Picrophyllite natural abrasive is a rare magnesium phyllosilicate crushed for specialty soft abrasives in optical polishing. The crushing is a permitted mechanical process, and the product falls under tariff item 2513.20.00 as other natural abrasives.
Raw Arkansas Stone Lumps
Raw Arkansas stone lumps are crude novaculite fragments, a premium natural sharpening abrasive. These lumps are unprocessed, without heat treatment or sizing, and qualify as other natural abrasives under tariff item 2513.20.00.
Raw Natural Garnet Pieces
Raw natural garnet pieces are crude, irregular fragments of almandine garnet from alluvial deposits, used as waterjet cutting abrasive feedstock. They are not heat-treated or sized, maintaining natural shapes, and fall under tariff item 2513.20.00.
Unprocessed Staurolite Sand Lumps
Unprocessed staurolite sand lumps are crude, irregular lumps of the staurolite mineral, valued for angular hardness in paint and abrasive applications. These lumps are raw, without heat treatment, and qualify as other natural abrasives under tariff item 2513.20.00.
Unrefined Rottenstone Pieces
Unrefined rottenstone pieces are irregular fragments of decomposed siliceous limestone used for fine abrasion. These pieces are in a crude state, without processing beyond extraction, and fall under tariff item 2513.20.00 as other natural abrasives.
