Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If petroleum sulfonate modified
Certain chemically modified versions shift per subheading note (a)(3).
If rubbery characteristics dominate
High rubber content classifies as synthetic rubber in Chapter 40.
If styrene blocks <95%
Fails specific styrene polymer criteria, defaults to other scrap.
