Sodium Perfluorooctanoate
Sodium perfluorooctanoate (C7F15COONa) is the sodium salt form of PFOA, classified under HTS 2915.90.18.10 per Chapter Note 5(C)(1) which directs organic salts to the heading of the parent acid. Used in surfactant applications and chemical synthesis.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sodium salt has different chain length or partial fluorination
Only specifically named perfluorooctanoate salts fall in 2915.90.18.10; others go to the residual 'other acids' category.
If misclassified as primarily an inorganic sodium compound
Sodium salts of inorganic acids fall in Chapter 28, but organic acid salts remain in Chapter 29 per chapter notes.
If when diluted in water or solvents beyond Chapter 29 allowances
Solutions exceeding safety/transport concentration limits are classified as preparations in heading 3824.

Import Tips & Compliance
• Submit detailed chemical composition data showing >95% purity as sodium perfluorooctanoate to prevent reclassification as mixtures
• Comply with REACH and TSCA pre-manufacture notifications due to PFOA restrictions in multiple jurisdictions
• Use UN-approved packaging for corrosive solids and include GHS labeling on all import documentation
