Import Tips
• Ensure the pellets are not printed or surface-worked, as this could move them to Chapter 49 under section note 2
• Verify that the comonomer content meets the 95% threshold to avoid misclassification
• If the pellets are sold with other components as a set, review section note 1 for potential classification as a mixture
