Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of ethylene copolymers instead
Predominant monomer shifts classification to cellular polymers of ethylene under 3921.13 if not 95% regenerated cellulose.
If cut and packaged for household retail sale
Finished household table/l kitchen articles of cellular plastics classify in 3924, not plates/sheets.
If rubber-regenerated cellulose blend predominates rubber
Material composition change to rubber-based cellular products moves to Chapter 40.

Import Tips & Compliance
• Ensure documentation proves industrial end-use to distinguish from household articles under 3924 exclusions
• Test for predominant regenerated cellulose content (>95% by weight) as per Chapter 39 subheading note (a)(1)
• Package in bulk rolls to avoid retail sizing limits triggering 3921 special rates per US note
