Import Tips
• Include lot-specific CoA with pH buffering specs (typically 2.34/9.60); biotech importers need this for validation
• Avoid stabilizer additives exceeding Chapter Note (f) limits to prevent reclass to mixtures
• For research use, declare 'not for human consumption' to bypass some FDA regs
