Import Tips
• Verify rebuild certification and documentation proving prior use to qualify under 'used or rebuilt' subheading
• Include detailed maintenance logs and original specs to avoid reclassification as new equipment
• Ensure compliance with semiconductor equipment export controls from origin country
