HTS Chapter 99 Updated — Multiple Special Tariff Duty Provisions Reflected
The USITC has published a revised HTS Chapter 99, which contains the special tariff provisions governing Section 301 China duties, Section 232 steel and aluminum additional duties, reciprocal tariff country-specific provisions, automotive and medium/heavy-duty vehicle tariffs, semiconductor and wood products duties, Section 201 safeguards, and duty suspension provisions, among others. Importers across virtually all product categories should verify that their entries are citing the correct Chapter 99 subheadings, as misclassification within this chapter can result in underpayment or overpayment of significant additional duties.
With over 2,500 duty rate instances and 860 duty suspension provisions now indexed in the latest Chapter 99 revision, the classification landscape for special tariff provisions is exceptionally complex — we strongly recommend a targeted classification review for any product lines subject to stacked additional duties, particularly those touching the 9903.01/9903.02 reciprocal tariff series or the 9903.88 Section 301 exclusion series.
