Import Tips

• Submit particle size distribution analysis confirming micronization specs; critical for proving pharmaceutical-grade processing without changing chemical identity

• Declare as 'Bulk Drug Substance' on commercial invoice; include pharmacopeial compliance certificates (USP/EP) for duty verification

• Ensure temperature-controlled shipping documentation (2-8°C) to prevent degradation during transit, avoiding reclassification as unfit material
