Sodium Tripolyphosphate STPP 94% Industrial Grade, CAS 7758-29-4

Sodium Tripolyphosphate (STPP), CAS 7758-29-4, offered as white crystalline powder with stated 94% specification for detergent, washing powder, soap, and ceramic-related industrial applications. Buyer review should focus on CAS confirmation, Na5P3O10 identity, industrial grade suitability, assay range, moisture/insoluble matter, pH, whiteness or bulk density if relevant, packing condition, COA readiness, and export documentation before RFQ placement.

Applications and sourcing options

Check whether this product fits the buyer's actual application.

Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Use context

Common applications

  • Detergent builder raw material procurement where STPP is permitted by local regulation
  • Industrial washing powder and cleaning formulation supply chains
  • Ceramic-related industrial applications requiring sodium phosphate material
  • Distributor stock replenishment for standard 25 kg bag inorganic phosphate products
How we compare

Sourcing options

  • Request STPP 94% industrial grade with full COA and SDS before confirming bulk order
  • Compare 94%, 95%, and higher-purity STPP offers based on assay, moisture, insoluble matter, and landed cost
  • Ask for pre-shipment inspection and sealed retained sample for container-load orders
  • Request FOB China port and CIF destination quotations with packing, lead time, and document list separated
  • Confirm whether customized specification, packing, or buyer label can be supported
Human review

Compliance notes

  • Request current COA, SDS, TDS/specification sheet, commercial invoice, packing list, and certificate of origin as applicable
  • Confirm exact declared product name, CAS number, HS code, and grade on export documents
  • Check destination-country phosphate restrictions, detergent formulation limits, and import registration requirements before purchase
  • Verify whether the material is classified as dangerous goods for the intended route and obtain written shipping classification from the supplier or forwarder
  • Supplier certifications shown include CCIC, CIQ, and ISO; buyers should request valid certificate copies and scope pages
  • No regulatory approval or destination compliance should be assumed from marketplace listing data alone
