Last updated: July 2026 dataNatural abrasives under HTS 2513 — including emery, natural corundum, and garnet — are mineral materials valued for their hardness and used in grinding wheels, coated abrasive products, and surface preparation applications. The US tariff schedule divides these materials between crude or irregular-piece forms (2513201000) and further-processed or not-elsewhere-specified grades (2513209000), with the latter covering sized, graded, or otherwise beneficiated material ready for direct incorporation into abrasive products. Natural corundum and garnet compete with synthetic abrasives such as fused alumina and silicon carbide, so pricing and specification comparisons are routine in procurement decisions.

Natural corundum is a mined mineral classified under HTS 2513, while fused (synthetic) aluminum oxide produced by electric furnace fusion falls under Chapter 28 as an artificial corundum. The distinction matters for tariff classification and for end-use specifications, as synthetic abrasives offer more consistent hardness and purity than natural corundum.
A certificate of analysis specifying particle size distribution, mineral composition, and processing history (e.g., whether the material has been crushed, screened, or washed) is the most useful supporting document. Material in irregular lump form with minimal processing is classified under 2513201000, while graded or sized abrasive grain ready for bonded or coated abrasive manufacture falls under 2513209000.
