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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If disodium instead of trisodium
Disodium phosphates fall under separate subheading 2835.22; sodium ion count determines classification per heading notes.
If blended with silicates
Complex salts with silicates for detergents may classify under 2839 if meeting double salt provisions of note.
If part of liquid detergent formulation
When incorporated into finished cleaning products, shifts to Chapter 34 for organic surface-active preparations.

Import Tips & Compliance
• Declare hydration state accurately; dodecahydrate has different weight/mole ratios affecting duty calculations
• Comply with TSCA registration for chemical imports and provide REACH-like documentation if from EU

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.
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.
