Import Tips
• Submit NMR or GC-MS spectra to confirm structure matching the subheading; impurities must not exceed Chapter 29 note (a) thresholds
• Declare as hazardous material under DOT 49 CFR; use UN-approved packaging for corrosive liquids
• Watch for reclassification if dissolved in solvents beyond transport needs—per note (e), solutions must be solely for safety
