To ensure consumer safety and legal compliance, prioritize suppliers with HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 (Food Safety Management) certifications. For entry into premium markets, look for BRCGS (British Retail Consortium Global Standard) or IFS Food certifications. If your target audience has specific dietary needs, verify Organic (USDA or EU Organic), Kosher, or Halal certifications. Always request a Certificate of Analysis (COA) for every batch to check for pesticide residues and heavy metal limits.
