Import Tips

Provide rebuild invoices and test reports post-refurbishment; US Customs requires proof it's not 'new' to qualify for used rates

Declare precise wafer thickness capabilities in entry docs; mismatch leads to reclassification

Check for dual-use export licensing if grinder supports advanced node semiconductors
