Didecylmethylammonium Perfluorooctane Sulfonate 98% Pure
High-purity (98%) version of this quaternary ammonium salt, chemically defined with minimal impurities. Falls under HTS 2923.40.00.00 per Chapter 29 note (a) as a separate chemically defined organic compound. Commonly used in research and industrial fluorosurfactant synthesis.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing sulfur atoms directly linked to carbon beyond sulfonate
Organo-sulfur compounds in 2930 take precedence if structure qualifies, but standard PFOS remains quaternary ammonium salt.
If diluted with anti-dusting agents rendering it for specific industrial use
Chapter 29 note (g) excludes additions that make it particularly suitable for specific use, shifting to chemical preparations.
If classified primarily by the perfluorooctane chain as halogenated hydrocarbon derivative
If ammonium function secondary, it may fall under halogenated derivatives in 2903, but quaternary salt nature prevails per Chapter notes.

Import Tips & Compliance
• Submit Safety Data Sheets (SDS) and purity assays to customs for verification against HTS 2923.40.00.00 specificity
• Avoid misdeclaration as a mixture; Chapter 29 prioritizes pure compounds over formulations
• Check for REACH or TSCA pre-registration if transshipping from EU; PFOS compounds face import scrutiny
