HTS Chapter 99 Updated — Special Duty Provisions Reflect Current Tariff Landscape
The USITC has ingested a revised version of HTS Chapter 99, which contains the full range of special tariff provisions including Section 301 China duties, Section 232 steel and aluminum duties, reciprocal tariff country-specific provisions, automotive tariffs, semiconductor duties, wood products duties, medium- and heavy-duty vehicle duties, Section 201 safeguard duties, and CAFTA-DR tariff-rate quota provisions. Importers should confirm their Chapter 99 secondary subheadings are current given the breadth of active special-duty programs captured in this revision.
Chapter 99 is the most operationally complex part of the tariff schedule right now — with overlapping Section 301, Section 232, reciprocal, and automotive duty stacks, even a minor classification error in the primary chapter can cascade into a wrong Chapter 99 provision and significant duty exposure; we treat Chapter 99 alignment as a mandatory step in every classification review.
