Human review

Compliance notes

  • Request current COA matching the exact batch and specification before shipment
  • Verify CAS 134-03-2, E301 designation, food-grade status, and applicable food additive standard for the destination market
  • Request MSDS/SDS, TDS/specification sheet, allergen statement, GMO statement, residual solvent statement, heavy metal report, and microbiological test report where required
  • Confirm whether product is manufactured under relevant food safety systems such as ISO, HACCP, FSSC, GMP, or equivalent, if needed by buyer
  • Confirm HS code 2936270020 with customs broker; final classification may depend on destination rules and product presentation
  • Check destination-country permitted-use rules, labeling requirements, and maximum use levels through local regulatory counsel or importer of record
  • Confirm dangerous goods status with supplier SDS and forwarder before booking; do not rely only on marketplace listing
  • No regulatory approval, import clearance, or food-use permission is assumed from the listing alone
