Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If extruded into monofilament form
Processed into profiles/monofilaments over 1mm classifies under Chapter 39 plastics in primary forms, not bulk resin.
If rigid TPU grade
Non-elastomeric (high durometer) TPUs classify as 'Other' polyurethanes.
If supplied as ready-to-use 3D printing spool
Finished articles of plastic, not primary form polymers.

Import Tips & Compliance
• Specify Shore A hardness (elastomeric proof) in technical data sheets for CBP verification
• Classify as primary form only pre-extrusion; finished filament moves to 3916.90 or 3926.90
