How we compare

Sourcing options

  • Request 100 g to 1 kg sample with matching sample COA before commercial order
  • Start with 1 MT trial order if documentation and sample approval are satisfactory
  • Request 25 kg bag packing as standard, with palletized export packing if needed
  • Ask for full-container quote based on listed 24 MT/20 ft loading
  • Consider third-party pre-shipment inspection for first order or high-value shipment
  • Compare with suppliers offering food-grade certification and cosmetic-grade documentation specific to India buyer needs
Human review

Compliance notes

  • Verify CAS 24634-61-5, product name, assay range, and E202/food additive status against the buyer’s destination-market requirements before purchase
  • For India buyers, request current COA, SDS, TDS/specification sheet, allergen/non-GMO/BSE-TSE statements if relevant, and food/cosmetic documentation applicable to the intended channel
  • Confirm whether the offered grade is suitable for cosmetic use, food use, or both; do not rely only on marketplace category labels
  • Request declaration for heavy metals, residual solvents if applicable, microbiological limits if required by buyer specification, and any country-specific additive compliance documents
  • DG/export awareness: potassium sorbate is commonly shipped as general chemical cargo, but buyer should confirm the latest SDS transport classification, UN status if any, and carrier acceptance before booking
  • Ask for HS code confirmation, certificate of origin availability, invoice/packing list readiness, and whether third-party inspection such as SGS can be arranged
  • No regulatory approval, import clearance, or end-use compliance is guaranteed by the listing; buyer must validate with local importer, customs broker, and regulatory consultant
  • Avoid RFQs that request restricted applications, undeclared end use, false labeling, or document alteration
