Import Tips
• Include CAS 81-14-1 documentation and purity analysis; IFRA QRA required due to skin sensitization potential
• Declare exact nitro content; common pitfall is shipping in perfume alcohol (2209 territory)
• TSCA pre-manufacture notice may apply for first-time importers; check EPA inventory status
