Import Tips

Verify material composition with lab certification to confirm cast iron content over 99% iron alloy

Include detailed engineering drawings in documentation to prove it's a transmission part, not an engine component

Avoid misclassification as unfinished castings by ensuring it's machined for gear box assembly
