2840.20.00.00 - Other borates

This HTS classification, 2840.20.00.00, encompasses a broad range of borate compounds that are not specifically enumerated elsewhere within heading 2840. These include inorganic salts and peroxysalts of boric acid. Examples of products falling under this category may include various metal borates, such as sodium borates (excluding refined disodium tetraborate) and potassium borates, as well as more complex borate structures used in industrial applications, ceramics, glass manufacturing, and as flame retardants. The key criterion for inclusion is that the compound is a borate and not explicitly classified under a more specific subheading.

It is important to distinguish this category from its sibling, 2840.30.00, which specifically covers peroxoborates (perborates). While both are derived from boric acid, peroxoborates are characterized by the presence of a peroxide (O-O) group within their structure, imparting oxidizing properties. In contrast, 2840.20.00.00 includes borates that lack this peroxide linkage. Additionally, refined disodium tetraborate, commonly known as refined borax, has its own distinct classification and is therefore excluded from this category.

As a leaf node, 2840.20.00.00 does not have further subcategories. Classification under this subheading relies on the absence of a more specific designation for the borate compound in question, either within heading 2840 or in other headings of the Harmonized Tariff Schedule. Importers and exporters should carefully consider the chemical composition and intended use of their borate products to ensure accurate classification.
