Last updated: April 2026 dataTransmissions and gearboxes — covering both complete units and their parts, including cast iron housings and steel forgings — are classified across eleven 10-digit lines that distinguish passenger car applications (heading 8703), commercial vehicles, and agricultural tractors. Japan and Germany are significant suppliers alongside Mexico, reflecting the concentration of advanced automatic and dual-clutch transmission manufacturing in those countries. Section 232 tariffs apply to steel and aluminum content in certain gearbox components, and importers of cast iron parts (8708407000) or steel forgings (8708407570) should assess their exposure carefully.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
At the 10-digit level, gearboxes for vehicles of heading 8703 (passenger cars) are classified at 8708401110, while gearboxes for vehicles of subheadings 8701.21–8701.29, heading 8702, or heading 8704 (buses and trucks) fall under 8708401150. Agricultural tractor gearboxes have their own line at 8708403000. Importers must identify the intended vehicle type to select the correct line, as the duty treatment and any applicable trade remedy exposure can differ.
Yes. The US schedule provides a dedicated line for steel forgings used in gearboxes of vehicles under headings 8701–8705 (8708407570), distinct from cast iron gearbox parts (8708407000) and other gearbox parts (8708407580 and 8708408000). The material distinction is critical because Section 232 tariff exposure and any applicable antidumping orders may differ between cast iron and forged steel articles.
