Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated into surface-active preparations
Organic surface-active agents in Chapter 34 supersede primary polymer classification.
If epoxy-modified acrylics
Chemical modification places in 'other' epoxide resins per note (a)(3).
If extruded into primary forms > finished polymer
Natural resin modifications or specific forms move to heading 3913.

Import Tips & Compliance
• Include solubility test data and pH specs in entry documentation for polymer identification
• Ensure flakes remain uncompounded; adding surfactants risks Chapter 34 classification
• CBP often examines for finished cleaner content; maintain clear primary form segregation
