Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the membranes are made of plastics and sold as general plastic sheets.
Chapter 39 covers plastic sheets, but when specifically designed for primary batteries, they are classified as parts under heading 85.06.

Import Tips & Compliance
• Ensure the membranes are not classified as chemical products (e.g
• cellulose derivatives) under other chapters; their function as battery parts is key
• Provide technical datasheets to CBSA to demonstrate their role in primary battery operation
• Verify if the membranes qualify for duty-free treatment under specific trade agreements
