Diethylamine Perfluorooctane Sulfonate Technical Grade
Diethylamine perfluorooctane sulfonate technical grade is a salt formed between diethylamine and perfluorooctanesulfonic acid. As a salt of an amino-alcohol (diethanolamine) with a perfluoroalkyl sulfonic acid, it falls under tariff item 2922.16.00, which covers diethanolammonium perfluorooctane sulphonate. The technical grade contains impurities permitted by Chapter 29 notes, which do not alter its classification as a separate chemically defined organic compound.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is not specifically the diethanolammonium salt of perfluorooctane sulphonic acid but another amino-alcohol salt.
Other amino-alcohols and their salts not elsewhere specified fall under this residual tariff item.
If the product is presented as a heterocyclic compound rather than an acyclic amino-alcohol salt.
Certain perfluorinated sulfonamide derivatives may be classified as heterocyclic compounds if they contain a ring structure.

Import Tips & Compliance
• Ensure the product is clearly labeled with its chemical name and purity to support classification under 2922.16.00
• Provide a safety data sheet (SDS) to the CBSA if requested, as perfluorinated compounds may trigger additional scrutiny
• Verify whether the product is subject to Canada's Prohibition of Certain Toxic Substances Regulations, as PFOS-related substances are restricted
