Products classified under HTS 2840.30.00
Sodium Perborate Tetrahydrate
Sodium perborate tetrahydrate is a white, crystalline powder used primarily as an oxidizing agent in laundry detergents and bleaching applications. It falls under HTS 2840.30.00 as a peroxoborate, specifically the perborate salt of sodium, meeting the chemical definition for inorganic peroxo compounds in Chapter 28.
Sodium Perborate Monohydrate
Sodium perborate monohydrate is an anhydrous form of the perborate salt used in oxygen bleach powders and cleaning agents for its controlled release of hydrogen peroxide. Classified in HTS 2840.30.00 as a chemically defined peroxoborate of inorganic base sodium.
Potassium Perborate
Potassium perborate is a less common alkali metal peroxoborate used in specialized bleaching and disinfection formulations due to its solubility properties. It qualifies for HTS 2840.30.00 as a peroxoborate salt of potassium, an inorganic base per Chapter 28 notes.
Ammonium Perborate
Ammonium perborate serves as a source of active oxygen in denture cleaners and mild bleaching agents. Under HTS 2840.30.00 as a peroxysalt of ammonium, explicitly covered by headings 2826-2842 for ammonium salts per chapter notes.
Sodium Perborate Anhydrous
The anhydrous form of sodium perborate is used in high-temperature bleaching processes and as a reagent in chemical synthesis. HTS 2840.30.00 applies to all chemically defined peroxoborates regardless of hydration state.
Perborate Bleach Powder (Technical Grade)
Technical grade perborate bleach powder, typically 98%+ sodium perborate, is imported for detergent manufacturing. Falls squarely under HTS 2840.30.00 as chemically defined peroxoborates per subheading note.
Disodium Perborate
Disodium perborate, a specific crystalline form, acts as an oxygen liberator in laundry boosters. Classified in HTS 2840.30.00 as it meets the peroxoborate definition for sodium salts.
Sodium Perborate for Textile Bleaching
High-purity sodium perborate designed for textile industry bleaching processes, releasing peroxide under alkaline conditions. HTS 2840.30.00 covers this industrial-grade peroxoborate.
Perborate Oxygen Source for Denture Tablets
Pharmaceutical-grade sodium perborate used as the active oxygen component in effervescent denture cleaning tablets. Remains under HTS 2840.30.00 as the pure chemical compound, not the finished tablet.
Industrial Sodium Perborate Flakes
Large-flake sodium perborate monohydrate for bulk industrial applications in paper pulp bleaching. HTS 2840.30.00 for this peroxoborate physical form.
