High-Impact Polystyrene (HIPS) Trimmings
High-impact polystyrene trimmings are trimmed edges and parings from HIPS sheet extrusion used in refrigerator linings and packaging. This material consists of polystyrene modified with polybutadiene but retains 95% or more styrene units by weight, falling under tariff item 3915.20.00 as styrene polymer scrap.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the styrene content falls below 95% by weight
Copolymer scrap with significant rubber content is classified under other plastic waste.
If the trimmings are in sheet form and not yet waste
Unused HIPS sheets are classified as plates, sheets, or film rather than scrap.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify that the polybutadiene content does not push styrene below 95% by weight, as this changes classification
• Keep supplier certificates of analysis for polymer composition
• Ensure the trimmings are not contaminated with other plastics during collection and shipping
