Products classified under HTS 2513.20.90.00
Natural Garnet Abrasive Grit
Coarse angular grains of natural almandine garnet mined from alluvial deposits, heat-treated for consistent hardness. Classified under HTS 2513.20.9000 as 'other natural abrasives' distinct from pumice, fitting the category for raw mineral abrasives used in surface preparation.
Heat-Treated Natural Corundum Powder
Fine powder derived from naturally occurring corundum ore, thermally treated to enhance friability for polishing applications. Falls under HTS 2513.20.9000 as 'other natural abrasives,' encompassing mineral corundum excluding crude forms.
Natural Wollastonite Abrasive Powder
Micronized wollastonite mineral (calcium silicate) from natural deposits, used as mild abrasive in toothpaste and polishing compounds. HTS 2513.20.9000 includes such 'other natural abrasives' valued for low hardness (5-5.5 Mohs).
Natural Olivine Sand Abrasive
Crushed olivine (magnesium-iron silicate) from Norwegian mines, used in foundry cleaning and shipyard blasting. HTS 2513.20.9000 for this eco-friendly natural abrasive alternative to silica sand.
Picrophyllite Natural Abrasive
Rare natural picrophyllite (magnesium phyllosilicate) crushed for specialty soft abrasives in optical polishing. Classifies in HTS 2513.20.9000 as other natural abrasives with Mohs hardness ~3.
Natural Emery Coarse Grain
Crushed and screened grains from natural emery rock, a corundum-garnet mixture from Naxos deposits. HTS 2513.20.9000 covers this as 'other natural abrasives,' heat-treated or not, for use in tumbling and blasting.
Almandine Garnet Sandblasting Media
Washed and sized almandine garnet sand from Indian river deposits, optimized for paint removal in surface prep. Classed in HTS 2513.20.9000 as natural garnet abrasive, distinguished by angularity and silica-free nature.
Diatomaceous Earth Abrasive Grade
Calcined diatomite (amorphous silica from fossil diatoms) selected for gentle abrasive polishing in metal buffing. Under HTS 2513.20.9000 as 'other natural abrasives,' separate from filter-grade under 2512.
