Import Tips
• Provide detailed chemical analysis and CAS number (123-81-9) to confirm identity and purity for CBP classification
• Include safety data sheets (SDS) documenting stabilizer content to comply with Chapter 29 note (f) on transport additives
• Avoid misclassification as a finished formulation; import as pure compound to prevent duty shifts to Chapter 38
