2513.20.10.00 - Crude or in irregular pieces

This HTS category, 2513.20.10.00, specifically encompasses natural abrasives such as emery, corundum, and garnet that are presented in their raw, unprocessed state. This includes materials that are crude or have been broken into irregular pieces. The primary characteristic for inclusion here is the absence of further shaping, grinding, or refinement beyond initial extraction and breakage, ready for potential further processing into finished abrasive products.

Distinguishing this classification from its sibling, 2513.20.90.00 ("Other"), is crucial. While 2513.20.90.00 would cover natural abrasives that have undergone any form of treatment or processing beyond simply being in crude or irregular pieces – such as being cut, ground, graded by size, or heat-treated to enhance their abrasive qualities – this category is strictly for the rawest forms. The defining factor is the degree of processing.

As this is a leaf node in the HTS structure, there are no further subcategories under 2513.20.10.00. Therefore, the classification hinges entirely on the physical state of the natural abrasive material. Importers and exporters should carefully assess whether the abrasive material is presented in its most basic, fragmented form, or if it has been subject to any refining or shaping processes that would place it under the "Other" category at this level.
