Import Tips
• Confirm the film is cellular (microporous) and not a solid sheet with perforations
• If the separator is part of a battery, check if it is classified as a part of an electrical article (Section XVI) rather than as a plastics sheet
• Keep technical data on pore structure and thickness for CBSA inspection
