HS Code 8459.70 – Machine-tools; for threading or tapping by removing metal
HS code 8459.70 is the 6-digit subheading for machine-tools, for threading or tapping by removing metal. It is used for threading machines, tapping machines, bolt threading machines, pipe threading machines and nut tapping machines.
What HS 8459.70 covers
This HS code covers specialized machine tools designed specifically for creating threads (internal or external) or tapping holes by removing metal. These machines are crucial for producing fasteners, pipe fittings, and components that require precise screw threads for secure assembly. They range from simple manual tapping machines to sophisticated CNC threading lathes or dedicated tapping centers. Industries such as automotive, plumbing, construction, and general manufacturing rely heavily on these tools for ensuring secure and accurate connections. Importers include countries with strong manufacturing sectors that produce goods requiring threaded components, as well as those involved in maintenance and repair. Exporters are typically nations with advanced machine tool industries or those specializing in specific threading technologies. The trade in these machines is essential for the production of countless everyday items and complex industrial assemblies, ensuring compatibility and functionality across various applications.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
