Import Tips
• Verify chemical purity and provide assay certificates to confirm it meets 'chemically defined' criteria under Chapter 28 Note 1
• Include Safety Data Sheets (SDS) and CAS number (10042-45-2) in documentation for customs clearance
• Avoid common pitfalls like classifying as a mixture if stabilizers exceed 5%; test for homogeneity
