HS Code 8607.30 – Railway or tramway locomotives or rolling stock; parts, hooks and other coupling devices, buffers and parts thereof
HS code 8607.30 is the 6-digit subheading for railway or tramway locomotives or rolling stock, parts, hooks and other coupling devices, buffers and parts thereof. It is used for automatic couplers, screw couplers, drawbars, buffer assemblies and buffer springs.
What HS 8607.30 covers
This HS code encompasses hooks, other coupling devices, buffers, and their parts, all essential for railway or tramway locomotives and rolling stock. These components are fundamental to connecting rail vehicles, absorbing impact, and ensuring the safe and efficient movement of trains. The international trade in these parts is vital for the construction of new rolling stock, as well as for the maintenance and repair of existing fleets globally. Manufacturers specialize in robust, high-strength components designed to withstand extreme forces and varying operational conditions. Importers and exporters include rolling stock manufacturers, railway operators, and specialized engineering firms, with a strong emphasis on durability and compliance with international rail standards.

Codes often confused with 8607.30
Common mistake. This code might be confused with 860799 (other rolling stock parts n.e.c.) if the specific function as a coupling or buffering mechanism is not clearly defined. It's distinct due to its explicit mention of these critical connection components.
Top exporters and importers of HS code 860730, 2025
In 2025, the largest exporter of HS code 860730 in UN Comtrade data was China, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 10% of world imports. Mexico reports $267M of its chapter 86 imports without product detail (confidential), so its figure here may be too low and it may rank higher.

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).
