Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fabricated into finished medical components
Completed medical instrument parts shift to 3926.90.45 rather than stock material for fabrication
If confirmed as primarily polycarbonate
Polysulfone contamination in polycarbonate sheets would classify by predominant monomer per note (a)(4)
If Medical device parts classified by function in Chapter 90 regardless of plastic material

Import Tips & Compliance
• Include USP Class VI and biocompatibility certificates with entry; test for extractables/leachables if questioned by FDA/Customs
• Ensure declaration specifies 'stock sheets only' to prevent medical device classification under 9018
