Product classification
HS code for Transmission: 8708.40
Vehicle parts, gear boxes and parts thereof.
Classification of transmission under HS 8708.40
Vehicle transmissions, or gear boxes, are classified under HS code 8708.40. This code is part of Chapter 87, which covers vehicles other than railway or tramway rolling-stock, and their parts and accessories. Heading 8708 is specifically designated for parts and accessories of the motor vehicles of headings 8701 to 8705, which include tractors, passenger cars, trucks, and special purpose vehicles. Subheading 8708.40 covers gear boxes and parts thereof. The classification is driven by the intended use of the component as a dedicated part of a motor vehicle. It includes manual, automatic, and semi-automatic transmissions, as well as the individual components that make up the gear box assembly, such as shafts, gears, and housings, provided they are identifiable as being solely or principally for use with the vehicles mentioned in the heading. This follows GRI 1, which prioritizes the terms of the headings and subheadings.

Codes often confused with 8708.40
Common mistake. Transmissions are often misclassified under HS code 8483.40, which covers gears and gearing, including gearboxes and other speed changers for general machinery. The distinction lies in the application: if the gearbox is designed specifically for a motor vehicle of Chapter 87, it must be classified under 8708.40. If it is for an industrial machine or a stationary engine, it falls under 8483.40. Additionally, drive-axles with differentials are sometimes confused with transmissions but belong under 8708.50.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
