Import Tips & Compliance
• Document die-cut process to distinguish from simple rectangular sheets of 4006.10
• Ensure no surface working beyond cutting, as further processing moves to heading 4008 definitions
• Test for permitted additives only (emulsifiers, antioxidants) to maintain raw material status
