Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as polymer pellets, not formed sheets
Unformed PS resins classify in Chapter 39 primary forms, not plates/sheets.
If thermoformed into custom inserts
Formed plastic packaging components become other articles in 3926.
