How we compare

Sourcing options

  • Request food-grade sodium propionate with 25 kg/bag export packing
  • Request cosmetic-suitability review with enhanced impurity and microbiological specification
  • Request sample plus COA before bulk RFQ
  • Request third-party lab testing for Vietnam-bound shipment batch
  • Request FOB China port quotation for 1 MT MOQ and CIF quotation to Ho Chi Minh City or Hai Phong
  • Request supplier comparison against FCC/E281 or buyer-provided specification
Human review

Compliance notes

  • Verify CAS 137-40-6, formula, and product name against COA, SDS, commercial invoice, and customs declaration
  • Request current COA, SDS, TDS/specification sheet, allergen statement if relevant, GMO statement if relevant, and certificate of origin if needed
  • Supplier page mentions HACCP, ISO, Kosher, Halal, and GMP-related standards; buyer should request valid certificates and scope pages rather than relying on listing claims
  • For Vietnam sourcing, confirm whether the intended use is food additive, feed additive, cosmetic preservative, or industrial input, because document and registration expectations may differ
  • Check whether sodium propionate is approved for the buyer’s intended product category and maximum-use level in the destination market; supplier statements should not be treated as regulatory approval
  • Confirm dangerous goods status for the selected transport mode with the supplier’s SDS and freight forwarder; do not assume non-DG status without document review
  • For cosmetic use, request cosmetic-grade suitability evidence, impurity profile, microbial limits, and any preservative-use documentation required by the buyer’s formulation and local compliance team
  • No regulatory guarantee is implied; final import, labeling, and use approval should be confirmed by the buyer or local compliance adviser
