As a food and supplement product, compliance is non-negotiable. You must verify HACCP and ISO 22000 certifications for food safety management. For entry into the US market, FDA registration and FSVP (Foreign Supplier Verification Programs) compliance are required. For the EU, ensure the product meets EFSA Novel Food regulations. If marketed as organic, the supplier must provide USDA Organic or EU Organic certificates. Always request a COA (Certificate of Analysis) for every batch to check for heavy metals, pesticides, and microbial limits.
