Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used primarily in metal electroplating baths
Preparations for electroplating may be classified in Chapter 28 based on principal use rather than chemical composition.
If for the free perfluorooctane sulfonic acid form
The corresponding sulfonic acid (not quaternary salt) classifies under halogenated/sulfonated hydrocarbons in 2903.

Import Tips & Compliance
• Obtain EPA pre-manufacture notice approval if considered a new PFAS chemical under TSCA
• Provide detailed end-use statement to avoid anti-dumping scrutiny on fluorochemicals
• Ensure packaging prevents moisture absorption which could affect chemical purity classification
