More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the film is made of cellulose acetate rather than regenerated cellulose
Cellulose acetate is a specific cellulose derivative with its own subheading.
If the film is cellular or reinforced, laminated, or supported
Cellular or reinforced/supported plastics fall under heading 39.21 rather than 39.20.
If the film is imported as a part of a capacitor
Parts of electrical capacitors are classified in Chapter 85, not Chapter 39.

Import Tips & Compliance
• Confirm the film is non-cellular and unsupported; if it is reinforced or laminated, it would fall under heading 39.21 instead
• Be prepared to demonstrate the regenerated cellulose composition and thickness to the CBSA
• If the film is imported as part of a capacitor, it may be classified under Section XVI (machines and mechanical or electrical appliances) rather than Chapter 39
