Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diluted in solvent beyond transport needs or contains additives for specific end-use
Solutions exceeding Chapter 29 note (e) limits or with functional additives classify as chemical preparations in 3824.
If classified as general perfluorooctane sulfonic acid rather than specific lithium salt
Parent acid form falls under earlier 2904 subheading; salts follow principal compound per Chapter notes.
If containing metal impurities exceeding trace levels affecting classification
High metal content may shift to inorganic compounds of lithium in Chapter 28.

Import Tips & Compliance
• Verify REACH and TSCA compliance due to PFOS environmental restrictions; obtain EPA pre-manufacture notice if needed
• Provide detailed chemical purity certificates and CAS number (29457-72-5) for customs verification
• Avoid misclassification as mixtures; ensure product is chemically defined per Chapter 29 note (a)
