Import Tips
• Provide GC-MS analysis confirming gamma isomer purity >99% to match HTS description exactly
• Declare as 'pure chemical for synthesis' to avoid pesticide classification; watch for anti-dusting agent additions
• Comply with TSCA import certification; common issue is improper UN packaging for hazardous goods
