Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the styrene content is below 95% by weight
Block copolymer scrap with significant isoprene content falls under other plastic waste.
If the scrap behaves as rubber rather than plastic
Waste of vulcanized rubber is classified under Chapter 40 if the material has rubber-like properties.

Import Tips & Compliance
• Confirm the styrene end-block content meets the 95% threshold through polymer analysis documentation
• Separate this scrap from other elastomer waste to avoid misclassification
• Verify that the scrap is not contaminated with isoprene-rich fractions that could affect tariff classification
