Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If silicone-modified for medical use
Silicones and modified siloxanes have separate Chapter 39 classification.
If polycarbonate blend for medical
Medical polycarbonate copolymers classified under polyester headings.
If pre-extruded into medical tubing
Finished medical articles shift from primary polymers to Chapter 39 end-use headings.

Import Tips & Compliance
• Provide biocompatibility test certificates and lot traceability documentation required for medical polymers
• FDA import alerts common - ensure supplier has drug master files on record
• Separate from regular SAN shipments to avoid cross-contamination concerns during customs inspection
