Import Tips & Compliance
• Submit manufacturer's spec sheet showing <0.5% impurities to affirm 'chemically defined' status
• Comply with EPA pre-manufacture notice if used in US formulations; bulk import reduces duties vs packaged goods

Sodium Perborate Monohydrate
Sodium perborate monohydrate (NaBO3·H2O) is a white, odorless powder used primarily as an oxidizing agent and bleaching agent in detergents and cleaning products. It falls under HTS 2840.30.0010 as it is a chemically defined peroxoborate (perborate) of sodium, explicitly classified in the borates subheading for peroxoborates.
Sodium Perborate Tetrahydrate
Sodium perborate tetrahydrate (NaBO3·4H2O), often called 'gem clips' in industry, is an anhydrous white crystalline powder that releases hydrogen peroxide in water for bleaching applications. Classified under HTS 2840.30.0010 as a peroxoborate of sodium per Chapter 28 notes for inorganic oxygen compounds.
Anhydrous Sodium Perborate
Anhydrous sodium perborate is the dehydrated form (NaBO3) used in high-performance bleaching formulations where water content must be minimized. It is specifically classified under HTS 2840.30.0010 as a peroxoborate (perborate), meeting the chemical definition for inorganic peroxy compounds in Chapter 28.
