2840.30.00.50 - Other

This classification, HTS Code 2840.30.00.50, encompasses "Other" peroxoborates (perborates) not specifically enumerated elsewhere within the peroxoborate heading. This category serves as a residual for peroxoborate compounds that do not fall under more specific subheadings. Typically, these are chemical substances characterized by the presence of the perborate anion, often existing in hydrated forms.

Distinguishing this category from its sibling, 2840.30.00.10 (Sodium perborate), is crucial. While sodium perborate is a well-defined compound, this "Other" category is for peroxoborates where the cation is not sodium, or for mixtures or less common perborate forms that are not predominantly sodium perborate. Classification here would depend on the specific chemical composition and identity of the peroxoborate in question.

As a leaf node, this category does not have further subcategories. Therefore, the focus for classification under HTS 2840.30.00.50 is on accurately identifying the chemical nature of the peroxoborate. Importers and exporters should refer to detailed chemical specifications, product literature, and potentially laboratory analysis to confirm that their product is indeed a peroxoborate and does not fit into any more specifically defined HTS subheading within Chapter 28.
