Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If separators made from other microporous plastics like polyethylene
Common battery separators from PE fall under 'Other plastics' subheadings.
If imported as parts of complete batteries
Parts of electric accumulators are classified with the finished battery in 8507.
If rigid or cellular separator material
Cellular or rigid plastic sheets for technical use shift to heading 3921.

Import Tips & Compliance
• Import as raw film stock; assembled batteries classify under 8507 with different duties
• Thickness certification needed; very thin films (<0.1mm) face additional scrutiny
• Ensure no impregnation with electrolytes at import, which changes classification
