Products classified under HTS 2835.29.30.00
Anhydrous Trisodium Phosphate Powder
Anhydrous trisodium phosphate is the water-free form of Na3PO4, a strong base used in metal pretreatment and food processing as an acidity regulator. It is explicitly covered by HTS 2835.29.30.00 as a chemically defined trisodium phosphate. This powder absorbs moisture readily, requiring sealed packaging.
Food Grade Trisodium Phosphate
Food-grade trisodium phosphate (USP/ FCC certified) serves as a sequestrant and pH adjuster in processed meats and cereals. It is classified under HTS 2835.29.30.00 as a pure trisodium phosphate meeting chemical definition standards. Strict purity controls ensure safety for ingestion.
Trisodium Phosphate Solution 20%
20% aqueous solution of trisodium phosphate used for pH adjustment in cooling towers and as a rust inhibitor. While solutions can be tricky, pure trisodium salts remain in HTS 2835.29.30.00 if chemically defined without organic additives. Concentration declared by weight.
Ultrahigh Purity Trisodium Phosphate
Ultrahigh purity (>99.99%) trisodium phosphate for semiconductor wafer cleaning and electronics manufacturing. Meets stringent trace metal specs for Chapter 28 chemical definition under HTS 2835.29.30.00. Packaged in cleanroom conditions.
Trisodium Phosphate Crystals
Trisodium phosphate (TSP) in crystalline form is a chemically defined inorganic salt of phosphoric acid with three sodium ions, used primarily as a cleaning agent and degreaser. It falls under HTS 2835.29.30.00 as a trisodium phosphate, distinct from other phosphate salts like disodium or monosodium variants. This white, water-soluble powder is common in industrial cleaners and water treatment.
Trisodium Phosphate Dodecahydrate
Trisodium phosphate dodecahydrate (Na3PO4·12H2O) is the hydrated form of the trisodium salt of phosphoric acid, widely used in detergents and as a pH buffer. Classified under HTS 2835.29.30.00 specifically for trisodium phosphates, whether pure or hydrated. Its high alkalinity makes it effective for heavy-duty cleaning.
Technical Grade Trisodium Phosphate
Technical grade trisodium phosphate meets industrial purity standards for use in boiler water treatment and textile processing. As a trisodium salt of phosphoric acid, it fits HTS 2835.29.30.00 for other trisodium phosphates. Lower purity than food grade but chemically defined.
Trisodium Phosphate Granules
Granular trisodium phosphate offers better flowability for automatic dispensing in industrial dishwashers and laundry systems. This form remains a chemically defined trisodium phosphate under HTS 2835.29.30.00. Granulation reduces dust compared to powder.
