2840.30.00 - Peroxoborates (perborates)

This HTS category, 2840.30.00, specifically enumerates and classifies peroxoborates, commonly known as perborates. These are inorganic chemical compounds characterized by the presence of the peroxy group (-O-O-) within the borate structure. Perborates are typically white crystalline solids and are primarily utilized for their oxidizing properties, finding widespread application as bleaching agents in laundry detergents, as disinfectants, and in other industrial processes requiring oxidation.

Distinguishing this category from its siblings, 2840.30.00 differs from "Disodium tetraborate (refined borax)" which is a simple salt of boric acid and lacks the peroxy linkage. It also differs from the broader "Other borates" (2840.20.00.00), which encompasses all borate compounds not otherwise specified and not containing the peroxy group. Therefore, the defining characteristic for classification under 2840.30.00 is the presence of the peroxy (-O-O-) bond within the borate molecule.

This category is further subdivided to provide more granular classification. The primary subcategory, 2840.30.00.10, specifically covers Sodium perborate, which is the most commercially significant perborate compound. The remaining perborate compounds, while less common, are classified under the residual category 2840.30.00.50, "Other." These subdivisions allow for precise tracking and tariff application based on the specific type of perborate.
