Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vinylidene chloride ≥95% by weight
Predominant monomer classifies under specific vinyl chloride/vinylidene chloride polymers per note (a)(1).
If for higher acrylonitrile content
Acrylonitrile-dominant copolymers shift to ethylene copolymers chapter.
If chemically modified beyond simple copolymer
Advanced modifications place in 'other' polyesters per note (a)(3).

Import Tips & Compliance
• Submit monomer weight percentage certificates; classification hinges on no single comonomer > all others per note (a)(4)
• Specify exact composition on commercial invoice to avoid misclassification as PVDC homopolymer (3904.61)
