Peroxoborates (Perborates)

Peroxoborates, commercially dominated by sodium perborate, are oxidizing agents used primarily as bleaching components in laundry detergents, denture cleaners, and industrial bleaching systems. The US tariff schedule distinguishes sodium perborate (2840300010) from other peroxoborates (2840300050), reflecting sodium perborate's outsized commercial importance relative to other salts in this class. Slovenia and Austria lead US imports — a pattern tied to European chemical producers that have historically supplied detergent-grade sodium perborate — with China and Germany also among the sources. Importers should note that peroxoborates are reactive oxidizers, which may trigger hazardous materials handling requirements during transport and warehousing.
