Import Tips
• Submit DEA Form 236 for List I chemicals if applicable; oversight leads to seizure as precursor under controlled substances act
• Include NMR/GC-MS spectra confirming structure; isomers fall under 2921.19.5000 'other' risking higher duties
• Limit package size <100g for research exemption; bulk imports require additional OPCW end-user certificates
