HS code for Threading machine: 8459.70
Machine-tools, for threading or tapping by removing metal.
Classification of threading machine under HS 8459.70
Threading machines that operate by removing metal are classified under HS code 8459.70. This code falls under heading 8459, which covers machine-tools for drilling, boring, milling, threading, or tapping by removing metal, other than lathes of heading 8458. The key technical requirement for classification here is the "removal of metal." This typically involves cutting tools, taps, or dies that shave away material to create the thread profile. This distinguishes these machines from thread rolling machines (8463.20). Subheading 8459.70 specifically identifies "other threading or tapping machines." This includes stationary or portable machines used in industrial settings for creating internal or external threads on pipes, bolts, and other fasteners. The classification remains here regardless of whether the machine is numerically controlled (CNC) or manual, provided the method of operation is metal removal. The machines classified here are often used in plumbing, construction, and automotive manufacturing. It is important to distinguish these from hand tools; heading 8459 is reserved for machine-tools, which are generally power-operated and designed to be fixed to the floor, a bench, or a wall.

Codes often confused with 8459.70
Common mistake. Threading machines are frequently confused with 8463.20 (Thread rolling machines). The difference is that 8459.70 machines cut the metal, while 8463.20 machines deform it. They may also be confused with 8458 (Lathes) if the threading is performed as a secondary function on a lathe.
Top exporters and importers of HS 845970 (the code used for threading machine), 2025
In 2025, the largest exporter of HS 845970 (the code used for threading machine) in UN Comtrade data was China, with 30% of world exports; the largest importer in UN Comtrade data was Thailand, with 11% 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 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).
