This articulated link chain features a pitch of 12.7 mm and contains more than 3 parts per pitch, including inner links, outer links, bushings, pins, and rollers, all made from stainless steel. It is classified under HTS 7315.12.0020 due to its small pitch under 50 mm and complex multi-part construction per pitch, distinguishing it from simpler chains. Commonly used in food processing and marine environments for its corrosion resistance.

Import Tips

Verify chain pitch measurement and part count per pitch with manufacturer specs to confirm HTS 7315.12.0020 classification

Provide material certificates proving iron/steel composition; stainless steel may qualify for duty exemptions under certain trade agreements

Avoid misclassification as machinery parts (HTS 84); include invoices specifying 'chain for power transmission' use
