PFOS Stabilized with Triethanolamine from China

PFOS stabilized with triethanolamine is perfluorooctane sulfonic acid with a stabilizer added for preservation. Under Chapter 29 note 1(f), the addition of a stabilizer necessary for preservation or transport does not change the classification, so it remains under this tariff item.

Import Tips

• Document the stabilizer's purpose and concentration to show it is for preservation, not for a specific use

• Verify that the stabilizer does not render the product particularly suitable for a specific use

• Check if the stabilized product meets Canadian environmental regulations for PFOS
