Import Tips

Verify material composition (e.g

aluminum alloy) via mill certificates to avoid misclassification under metal articles in Chapter 76

Include detailed engineering drawings in documentation to prove it's a dedicated gearbox part, not a general housing

Check for anti-dumping duties on Chinese-origin parts; obtain scope rulings if unsure
