Import Tips

• Document piston compatibility with specific marine engine models to prove principal use

• Avoid over-machining during import prep; excess work disqualifies from this low-duty rough casting category

• Use material certs showing <2.1% carbon for cast iron to prevent steel alloy misclassification
