  • Declaration for each genetically modified ingredient meeting the threshold
  • Compliance documentation in the supply chain (traceability)
  • Review of all compound ingredients for GMO content
Common Violations
  • Not disclosing GM ingredients above the threshold
  • Claiming "Non-GMO" without verified supply chain documentation
  • Not reviewing compound ingredients for GMO content
  • Inconsistent declarations across product variants
Examples: Compliant vs Non-Compliant
