Ferrosilicon 55.5% Borderline Grade from China

Ferrosilicon 55.5% Grade sits at the minimum threshold with precisely 55.5% silicon by weight, used in cost-sensitive steel alloys. Falls under HTS 7202.21.50.00 as 'other' ferrosilicon >55% up to 80% Si, distinguished from ≤55% category. Tight composition control essential.

Import Tips

Triple-check Si assay; values ≤55.00% reclassify to 7202.21.10.00, affecting duty rates significantly

Use independent third-party testing for borderline compositions to preempt CBP challenges
