Understanding Trisodium Phosphate (TSP) Specifications, Grades and Supplier Selection

Choosing the right Trisodium Phosphate (TSP) (磷酸三钠) comes down to reading the specification sheet correctly. This guide explains the numbers that matter and how to select a supplier you can trust.

Key Specifications of Trisodium Phosphate (TSP)

As an TSP water softener, the product is defined by a small set of parameters:

• Molecular formula: Na3PO4

• CAS No.: 7601-54-9

• Appearance: White powder

• Packaging: 25/50/1000kg woven bag lined plastic

• Standard: HG/T2517-2009, GB25565-2010

Grade and Quality Considerations

Not all water plant auxiliary chemicals are equal. For Trisodium Phosphate (TSP), confirm active content, moisture and impurity limits against the cited standard. A reputable TSP water softener supplier provides a Certificate of Analysis (COA) per batch and supports third-party testing.

Selection Checklist

1. Match the application: Water soften agent and remover agent for water treatment; food-processing, medical, agriculture, metal finishing.

2. Confirm packaging matches your handling (drum vs. bag, 25/50/1000kg woven bag lined plastic).

3. Verify the standard (HG/T2517-2009, GB25565-2010) and request documentation.

4. Check lead time and container-load options for export.

Storage and Handling

Store Trisodium Phosphate (TSP) in a dry, ventilated area away from incompatible substances. Follow the MSDS for PPE and spill response. Many buyers combine this product with Dipotassium Hydrogenphosphate (DKP) in a single sourcing plan to reduce freight and admin cost.
