Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-thermoplastic or rigid thermoset variant
Non-thermoplastic versions of these resins classify under 3911.90.40, separate from thermoplastic subheading.
If polyvinyl chloride copolymer blend predominates
Blends where PVC monomers exceed others shift to 3904 per subheading note (a)(4) predominance rule.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Provide manufacturing process documentation proving coumarone/indene aromatic monomers predominate by weight
• Avoid packaging that suggests finished form to stay in primary classification
• Common pitfall: misdeclaration as synthetic rubber leading to 4002 audits
