Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ethylene monomer predominates >50%
Subheading notes require classification by weight-predominant monomer; high ethylene shifts to 3901.
If for pure polyvinyl chloride polymers
If vinyl chloride (not fluorinated) is the main component, it moves to PVC-specific subheading.
If extruded into non-primary sheets
Primary forms only; any shaping or fabrication classifies as plates/sheets under 3920.

Import Tips & Compliance
• Include copolymer ratio documentation showing predominant halogenated olefin content
• Avoid bulk packaging that suggests finished goods; use industrial pellet bags
