Ammonium Perfluorooctanoate
Ammonium perfluorooctanoate is the ammonium salt of perfluorooctanoic acid (C7F15COO⁻NH4⁺), explicitly covered under HTS 2915.90.18.10 as a salt of this specific perfluorinated carboxylic acid. It was historically used as a processing aid in fluoropolymer production like Teflon.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by the quaternary ammonium cation rather than the PFOA anion
Quaternary ammonium salts are classified in heading 2923 when the nitrogen function dominates over the carboxylic acid function.
If containing inorganic fluoride impurities exceeding organic compound purity standards
Inorganic metal fluorides or compounds fall under Chapter 28 when not meeting Chapter 29 organic compound criteria.
If for sodium or potassium salts of PFOA rather than ammonium
Different metal salts of the same acid may fall under the initial 'salts' provision before the specific PFOA subheading.

Import Tips & Compliance
• Provide laboratory analysis confirming ammonium salt composition and PFOA content to support classification under the specific subheading
• Declare TSCA import certification and check for PFOA Significant New Use Rule (SNUR) compliance before importation
• Ensure proper hazardous material labeling and packaging per DOT regulations for safe transport of this fluorinated salt
