U.S. imports of Sodium Triphosphate (Sodium Tripolyphosphate) (SITC 52364) totaled $4.9M in August 2026, imported from 15 countries.
Importers of Sodium Triphosphate (Sodium Tripolyphosphate) paid $395K in duties in August 2026, an average duty rate of 8.03% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Sodium Triphosphate (Sodium Tripolyphosphate) imports of $4.9M in August 2026 ran 18% below the year-to-date monthly average of $6.0M.
Last updated: August 2026 dataSodium tripolyphosphate (STPP) is a condensed phosphate salt widely used as a builder in detergent formulations, a moisture-retention agent in seafood and meat processing, and a dispersant in ceramics and paper manufacturing. Its food-contact applications mean that food-grade STPP imported for direct use in processed foods may be subject to FDA review, while detergent-grade material faces no such admissibility requirement. Importers should specify grade and intended use clearly in entry documentation, as food-grade and industrial-grade STPP may be priced and classified differently.

Yes. Food-grade STPP used as a food additive or seafood processing aid falls under FDA jurisdiction and must comply with applicable food additive regulations. Industrial or detergent-grade STPP does not trigger the same admissibility review. Clearly stating the grade and end use on commercial invoices and entry documents helps avoid delays at the port.
The largest demand segments are household and industrial detergent manufacturing (where STPP acts as a water-softening builder), seafood and poultry processing (where it reduces moisture loss), and ceramics production (where it functions as a deflocculant). Detergent-sector demand has shifted in some markets due to phosphate restrictions in cleaning products, making food and industrial applications increasingly important for trade volumes.
