Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not explicitly trisodium (e.g., mixed sodium salts)
Other sodium phosphates without trisodium specification use 2835.29.50.
If used as catalyst additive
Antiknock preparations containing phosphates classify under 3811 as fuel additives.
If mineral fertilizer mix
Phosphatic fertilizers excluding pure compounds go to Chapter 31 per exclusion notes.

Import Tips & Compliance
• Specify 'technical grade' on commercial invoice with assay percentage to distinguish from USP/food grades
• Check for anti-dumping duties if sourced from specific countries; monitor ITC notices

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.
