Import Tips

Use ultrasonic testing reports to prove no internal machining; rough surfaces are key to this classification

Avoid packaging with lubricants or coatings, as they may imply post-forging treatment

For high-volume imports, pre-apply for binding ruling on 'processing' definition to prevent port disputes
