Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily halogenated hydrocarbon
Chapter note prioritizes parent hydrocarbon if halogen dominates over ketone function.
If sulfonated rather than halogenated
Sulfonated aromatic ketones have separate statistical suffix.
If imported pre-polymerized
Polymerized forms shift to Chapter 39 plastics.

Import Tips & Compliance
• Provide polymer manufacturer end-use letters if challenging industrial vs. general classification
• Confirm <0.1% impurities per chapter note (a); high purity critical for duty determination
• Package in nitrogen-flushed containers to prevent hydrolysis during ocean transit
