Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high filler/additive content
Prepared binders with significant non-polymer additives classify as chemical preparations.
If non-elastomeric masterbatch
Rigid PU masterbatches go to 'Other' polyurethane subheading.
If vulcanized into rubber plates/sheets
Hardened elastomers become Chapter 40 rubber products.

Import Tips & Compliance
• Document additive content <5% to maintain primary polymer status; higher shifts to compounded plastics
• Distinguish from color concentrates which may classify under 3204+ if dye-dominant
• CBP may test for true polyurethane content via spectroscopy
