HTS Chapter 99 Refreshed: Special Tariff Provisions Including Section 232, 301, Reciprocal, and Safeguard Duties
The USITC has updated HTS Chapter 99 in the ACE tariff schedule, encompassing duty suspension provisions, additional duty provisions, and classification workflows covering Section 232 (steel, aluminum, copper), Section 301 China tariffs, reciprocal tariffs, automotive and semiconductor tariffs, wood products, and safeguard duties — all of which stack on top of normal column 1 rates.
Chapter 99 is where most of our clients' landed-cost surprises originate; with this refresh we are re-verifying all active additional-duty overlays for our portfolio, and we encourage importers to request a duty-stacking audit if they haven't had one recently.
