Who uses this page

Target buyers

  • Industrial phosphate distributors
  • Food additive importers requiring verified DSP documentation
  • Water-treatment chemical buyers
  • Detergent and cleaning-product raw material buyers
  • Chemical formulators using sodium phosphate dibasic
  • Overseas buyers seeking bulk sodium phosphate supply from China
Before matching

Documents to check

  • CAS number, grade, assay, and impurity profile
  • SDS, COA, TDS, HS code, and transport classification
  • Destination-market import documents before supplier matching
Package and route

Packing notes

  • Listed packing: 25 kg net bags
  • Packing described as polyethylene inner bag with compound plastic woven outer bag
  • Transport package also described as kraft paper bags or plastic woven bags with PE liner
  • For export RFQs, request palletization details, container loading quantity, bag markings, batch labels, and moisture-protection measures
  • Confirm whether neutral export packaging, food-grade packaging, or industrial-use packaging is available for the intended market
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

  • Ingredient or additive sourcing where sodium phosphate dibasic dodecahydrate is specified
  • Industrial formulation requiring phosphate buffering or sequestration functions, subject to buyer validation
  • Water-treatment chemical procurement where DSP specification and impurity limits are confirmed
  • Detergent or cleaning formulation procurement where grade, solubility, and heavy-metal limits are checked
  • Food additive sourcing only where destination-market permissions and food-grade documentation are verified
How we compare

Sourcing options

  • 25 kg bag supply for trial or regular import orders
  • Bulk palletized shipment for distributor stocking
  • Ocean freight for larger quantities, subject to document and logistics review
  • Air freight consideration for small quantities only after confirming transport classification and documentation
  • Supplier-assisted export documentation and forwarder coordination, subject to buyer verification
Human review

Compliance notes

  • CAS and hydrate form require confirmation because the page lists anhydrous, dihydrate, and dodecahydrate references while the selected CAS is 10039-32-4
  • Request current COA, SDS, TDS/specification sheet, certificate of origin, packing list, commercial invoice, and any applicable food-grade or quality certificates
  • Do not rely on platform labels such as RoHS, ISO, or audited supplier status as proof of destination-market compliance without reviewing certificates
  • Confirm whether the product is supplied for food additive use, industrial use, detergent use, or water-treatment use, as documentation and impurity thresholds may differ
  • Check destination-country requirements for phosphates, food additives, heavy metals, labeling, and customs classification before import
  • Confirm DG classification and transport status with the supplier’s latest SDS and forwarder review; do not assume non-DG shipment without documentation
  • Supplier claims and standards should be independently verified against batch-specific documents and buyer specifications
