Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as component in anti-knock preparations or additives for fuels
Functional mixtures for specific uses beyond pure compounds classify in 3811.
If declassified from PFOS structure to general halogenated hydrocarbons
Loss of sulfonate function would revert to parent 2903 fluorocarbon classification.
