Import Tips & Compliance
• Include veterinary certificates proving unfitness for human consumption to avoid Chapter 2 or 16 misrouting
• Declare exact animal species (e.g
• bovine, deer) as CITES may apply for endangered sources like wild boar
• Avoid packaging that suggests 'food grade' to prevent FDA holds under exclusion (a)
