Import Tips
• >- Provide the film's microporous structure and thickness data to support the cellular classification
• Ensure the product is declared as a sheet/film, not as a finished curtain, to avoid classification under a different heading
• If the film is cut to specific lengths for curtains, verify whether it remains classifiable as a sheet
