Compliance is non-negotiable for cross-border entry. For the US market, ensure products meet FDA (Food and Drug Administration) standards. For the EU, LFGB (Lebensmittel- und Futtermittelgesetzbuch) certification is required, which is often stricter than FDA. Additionally, check for REACH compliance regarding chemical substances in plastics and ISO 9001 for manufacturing quality management. If the product is marketed as eco-friendly, look for GRS (Global Recycled Standard) or Biodegradable Certifications.
