Import Tips

• Verify compounding is limited to carbon black or silica per Chapter 40 notes; excessive additives like plasticizers may shift to heading 4004

• Provide lab analysis certificates confirming unvulcanized state and essential character as raw material to avoid misclassification

• Ensure documentation distinguishes from vulcanized products, common pitfall leading to higher duties under heading 4011
