Import Tips
• Verify comonomer composition via supplier certificates to confirm >95% VF/HFP content meeting subheading (a)(2)
• Import as primary forms (pellets/gum); finished articles shift to Chapter 39 headings like 3926
• Avoid misclassification as non-elastomeric fluoropolymers in 3904.69.20 by confirming elastomeric properties
