Import Tips
• Include USP/EP certificate and residual solvents analysis to justify pharmaceutical classification
• Declare end-use as pharmaceutical intermediate on CBP Form 3461 to potentially qualify for duty drawbacks
• Monitor heavy metal content (<10 ppm) as required for pharma imports; test certificates prevent FDA holds
