Import Tips
• Include FTIR or NMR spectra in documentation to confirm molecular structure matches perfluorooctanoic acid salt
• File TSCA Form A certification and be prepared for CBP requests for PFOA content verification
• Watch for misdeclaration as 'fluoride compounds' which would shift classification to Chapter 28 headings
