Import Tips
• TSCA pre-manufacture notification may be required if new chemical use; verify PMN status
• Provide isomeric ratio documentation (typically 60/40 ortho/para) and purity certificate (>98%)
• Avoid classification error with plasticizers (Chapter 39) which have different functional groups
