Package and route

Packing notes

  • Standard packing stated as 25 kg PP bag; confirm whether inner PE liner is included.
  • Confirm palletization, shrink wrapping, container loading quantity, and moisture protection for sea shipment to India.

  • Request shelf life, storage condition statement, and packaging photos before order 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 for laundry and dishwashing formulations
  • Water softening and dispersing additive in cleaning products
  • Deflocculant for ceramic and industrial slurry applications
  • Scale control or dispersing component in selected water treatment formulations
  • Food-grade moisture retention or texture applications only after local regulatory and specification verification
How we compare

Sourcing options

  • Industrial grade 96% STPP in 25 kg bags for detergent and ceramic use
  • Higher purity STPP within stated 90%-99% range, subject to COA confirmation
  • Food-grade STPP inquiry route with separate compliance documents and impurity limits
  • Low, medium, or high-density STPP options depending on formulation and handling needs
  • FOB China or CIF India port quotation with document review before order
Human review

Compliance notes

  • Confirm CAS number on COA/SDS because the source page lists EINECS but does not clearly show CAS in the extracted text.
  • Request current COA, SDS, TDS/specification sheet, packing list template, commercial invoice template, and certificate of origin availability.
  • For food-grade STPP, buyer must verify compliance with applicable India food additive requirements and end-use limits with local regulatory counsel or qualified compliance staff.
  • For detergent or industrial use, confirm import classification, labeling requirements, and any India-specific phosphate or environmental restrictions before shipment.
  • Check whether the cargo is classified as non-DG under supplier SDS and carrier booking documents; do not rely on marketplace labels alone.
  • Confirm heavy metals, arsenic, lead, fluoride, loss on ignition, P2O5, and Na5P3O10 assay if required by buyer specification.
  • Supplier claims audited/import-export status on Made-in-China should be independently verified through business license, export records, and pre-shipment inspection where needed.

  • Is the 96% material industrial grade only, or can food-grade STPP be supplied under a separate specification?
  • Can you provide full specification limits for Na5P3O10, P2O5, pH, insoluble matter, iron, whiteness, density, heavy metals, arsenic, lead, fluoride, and loss on ignition?
  • Which density grade is available for current stock: low, medium, or high density?
  • Is the material produced in-house or traded, and can batch traceability be provided?
  • What documents can be provided for India import: COA, SDS, TDS, certificate of origin, packing list, commercial invoice, and third-party inspection report?
  • What is the confirmed MOQ, lead time, monthly capacity, and validity period for pricing to Indian ports?
  • Can you quote FOB China port and CIF Nhava Sheva/Mundra/Chennai with container loading quantity?
