Import Tips

• Include GC-MS analysis certificate to confirm isomer purity; U.S

• Customs may test for compliance with Chapter 29 chemical definition

• Use UN-approved drums with nitrogen blanketing to prevent oxidation; common pitfall is inadequate stabilization leading to rejection

• Pre-register with EPA for TSCA inventory; provide end-use statement to avoid anti-dumping scrutiny on chemical intermediates
