2818.10.10.00 - Crude

This HTS category, 2818.10.10.00, specifically covers crude artificial corundum. Artificial corundum refers to aluminum oxide (Al2O3) that has been manufactured, as opposed to naturally occurring corundum. The "crude" designation signifies that this material has not undergone further processing such as grinding, pulverizing, or refining into specific grain sizes or purities for specialized applications. It represents the basic, unshaped form of manufactured aluminum oxide.

This classification is distinguished from its sibling category, 2818.10.20, by its state of processing. While 2818.10.10.00 encompasses the raw, unrefined material, 2818.10.20 covers artificial corundum that has been subjected to mechanical processing to produce grains, or has been ground, pulverized, or refined. This processing is often done to achieve specific particle sizes or higher purity levels for use in abrasives, refractories, or other industrial applications.

As a leaf node, this category has no further subcategories. Therefore, classification within this heading relies on identifying artificial corundum that has not been further processed beyond its initial production into a basic, unshaped form. This often includes large lumps, ingots, or masses of aluminum oxide.
