Human review

Compliance notes

  • Verify CAS 7758-29-4, molecular formula, and product identity against supplier COA and SDS before purchase
  • Clarify whether the offered 94% product is food grade, industrial grade, or dual-use grade with separate specifications
  • For food-related procurement, request food-grade declaration, applicable standard reference, allergen or additive documentation where relevant, and recent batch COA
  • Check impurity limits for fluoride, arsenic, lead, heavy metals, insolubles, and pH against the buyer's destination-market requirements
  • Confirm SDS format, labeling language, HS code, and shipping documentation required for Vietnam import clearance
  • DG classification and transport status should be confirmed from the current SDS and freight forwarder before shipment
  • No regulatory approval, food-use acceptance, or customs clearance outcome should be assumed from the listing alone
