Import Tips

• Verify material certification (e.g

• AISI 304/316) via mill test reports to confirm stainless steel and avoid reclassification to carbon steel headings

• Measure shank/thread diameter precisely (≥6mm) and document with caliper photos, as sub-6mm shifts to 7318.15.2095

• Include end-use declarations; industrial fasteners may qualify for duty exemptions under certain FTAs like USMCA
