HS Code 8479.90 – Machines and mechanical appliances; parts, of those having individual functions
HS code 8479.90 is the 6-digit subheading for machines and mechanical appliances, parts, of those having individual functions. It is used for robotic arm components, specialized valve assemblies, custom gearboxes, control panels for industrial machines and hydraulic cylinders.
What HS 8479.90 covers
This HS code covers the essential components and spare parts for the diverse range of specialized machines classified under heading 8479. These parts are critical for the maintenance, repair, and upgrade of industrial machinery across various sectors, ensuring operational continuity and efficiency. The global trade in these parts is robust, driven by the need to keep complex manufacturing and processing equipment running smoothly. Importers are typically manufacturing plants, maintenance service providers, and distributors who stock spares for their clients' machinery. Exporters are often the original equipment manufacturers (OEMs) or specialized parts suppliers, frequently located in countries with advanced manufacturing bases. Key aspects of this trade include the importance of compatibility, precision engineering, and timely delivery to minimize downtime in industrial operations. The market for these parts is directly linked to the installed base and operational lifespan of the machines they support, making it a significant indicator of industrial activity.

Codes often confused with 8479.90
Common mistake. Parts for specific machines might be misclassified under their respective machine's part code (e.g., 8471.90 for computer parts) if the machine itself has a more specific classification than 8479, or even general parts codes like 8487.00 if the function isn't clearly tied to a machine of heading 8479.
Top exporters and importers of HS code 847990, 2025
In 2025, the largest exporter of HS code 847990 in UN Comtrade data was Germany, with 16% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
