Duty Rates
General (Column 1 - MFN)
The duty provided in the applicable subheading + 25%
This is an ad valorem duty, meaning the import duty is calculated as a percentage (25%) of the declared value of the imported goods.
Column 2 Rate (Non-Tariff Treaty Countries)
This rate applies to countries without normal trade relations (most-favored-nation status) with the United States:
The duty provided in the applicable subheading + 25%
Column 2 rates are substantially higher than Column 1 rates and are rarely applied in modern international trade due to most-favored-nation agreements.
What HTS 9903.74.08 Covers
This is not a normal product classification but a Chapter 99 provision that applies an additional trade measure to medium- and heavy-duty vehicle parts described in subdivision (i) of the related U.S. note to subchapter III of Chapter 99. Goods reported here are always also classified under their regular Chapter 1-97 tariff line, with 9903.74.08 reported alongside it on the entry.
Notes for Importers
Affected products are parts for medium- and heavy-duty trucks and similar vehicles, such as engines, axles, transmissions and other components identified in the referenced note. Whether a shipment falls under this provision depends on the product scope in the U.S. note and the country of origin rules of the underlying action, not on the Chapter 99 number alone. Check the current text of the note and any exclusions before filing, because Chapter 99 measures change more often than the base schedule.
