Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polytetrafluoroethylene polymers made with fluorine
Fluoropolymers derived from fluorine classify in Chapter 39.
If trifluoroacetic acid from fluorine oxidation
Organic acids fluorinated move to Chapter 29.
If organic composite solvent with dissolved fluorine
Organic/inorganic composites go to 3814.
