Last updated: August 2026 dataSodium perborate, the dominant commercial compound in this heading, is a bleaching and oxidizing agent widely used in laundry detergents, dental products, and industrial cleaning formulations. The US schedule distinguishes sodium perborate (2840300010) from other peroxoborates (2840300050), with Slovenia and Austria — both European producers with established chemical manufacturing infrastructure — leading US import supply. Importers should note that China is also a significant source, and shipments from that origin warrant review for applicable Section 301 treatment.

Both sodium perborate monohydrate and tetrahydrate classify under 2840300010 as sodium perborate — the hydration level does not create a separate tariff line. However, the distinction matters commercially because monohydrate has higher active oxygen content and different solubility characteristics, which affects end-use suitability and may be specified in purchase contracts.
The entry should be supported by a supplier certificate of analysis identifying the compound as sodium perborate or another specific peroxoborate. If the product is a sodium perborate, it files under 2840300010; all other peroxoborates use 2840300050. Ambiguous product descriptions on commercial invoices are a common cause of classification disputes.
