Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing additional carboxylic acid functional groups beyond monocarboxylic
Polybasic carboxylic acids and their salts are classified later in numerical order per Chapter Note 3.
If for partially fluorinated rather than perfluorinated derivatives
Sulfonated or partially halogenated monocarboxylic acids fall under heading 2904 provisions.

Import Tips & Compliance
• 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
