Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as profiles of polymers of styrene
Pre-formed profiles/tubes are fabricated articles under 3916, not primary polymers.
If predominant monomer is methyl methacrylate
Note (a)(4) classifies by weight-dominant monomer to acrylic polymers heading.
If cellular articles of styrene polymers
Foamed/porous finished goods move to 3921 cellular plastics.
