2821.10.00.10 - Black 🖩

This HTS category, 2821.10.00.10, specifically covers black iron oxides and hydroxides when they are synthetically produced and intended for use as pigments. These materials are characterized by their deep black coloration, derived from the chemical structure of the iron compounds. Their primary function is to impart color to other substances, making them integral to various manufacturing processes across industries such as paints, coatings, plastics, inks, and construction materials.

Distinguishing this category from its siblings, 2821.10.00.20 (Red), 2821.10.00.30 (Yellow), and 2821.10.00.40 (Other), is crucial for accurate classification. While all fall under synthetic iron oxide pigments, the differentiating factor is the specific color achieved. This subcategory exclusively pertains to those formulations yielding a black hue, whereas the others encompass distinct red and yellow shades, or a broader collection of iron oxide pigments not fitting the preceding color specifications.

As this is a leaf node, there are no further subcategories. Classification within 2821.10.00.10 is determined by the synthetic origin of the iron oxide or hydroxide and its characteristic black pigmentary properties. Customs declarations should clearly indicate the synthetic nature of the material and its intended use as a pigment to ensure correct tariff application.
