Import Tips
• > Confirm that any ceramic or polymer coating is not visible to the naked eye, as that could move the product to Chapter 39
• Provide technical data on the nonwoven's porosity and weight for customs classification
• If the separator is part of a complete battery, it may be classified elsewhere
