Import Tips
• Verify microporosity through lab testing (e.g
• water vapor transmission rate >300g/m²/24hr) to confirm classification under 3921.19.0010
• Provide manufacturer specs on polymer content ensuring polyethylene monomers exceed 95% by weight per subheading note (a)(1)
• Avoid misclassification as non-cellular film under 3920.10; document cellular structure via SEM images or density <0.94 g/cm³
