Import Tips
• Provide detailed chemical purity certificates (GC/MS analysis) to confirm it meets 'chemically defined' criteria under Chapter 29 note (a)
• Ensure SDS includes CAS number (123-51-3) and verify not mixed with impurities exceeding 1% to avoid reclassification
• Label containers with UN number (1105) for hazmat compliance; common pitfall is improper transport documentation leading to CBP holds
