Product classification
HS code for Cold forming machine: 8463.90
Machine-tools, for working metal, sintered metal carbides or cermets, without removing material, n.e.c. in heading no. 8463.
Classification of cold forming machine under HS 8463.90
The classification of cold forming machines under HS code 8463.90 is determined by the machine's primary function: working metal without the removal of material. Unlike lathes or milling machines that cut away metal to achieve a shape, cold forming machines use high pressure to plastically deform metal at room temperature. This specific subheading, 8463.90, acts as a residual category for machine tools that perform metalworking operations not specifically named in other subheadings of 8463, such as draw-benches or thread rolling machines. The General Interpretative Rules (GIR) dictate that machines are classified based on their technical characteristics and the nature of the work performed. Since cold forming involves processes like heading, upsetting, or extruding without material loss, it fits squarely within the scope of heading 8463. This classification is essential for ensuring that the machinery is taxed according to its industrial application as a non-chip-removing metalworking tool.

Codes often confused with 8463.90
Common mistake. Cold forming machines are frequently confused with HS code 8462, which covers machine tools for forging, die-stamping, or hammers. While both involve deformation, 8462 is specific to forging processes. Another common error is 8459, which covers machines that remove metal (like drilling or milling). If the machine removes even a small amount of material as part of its primary shaping process, it cannot stay in 8463.
Top exporters and importers of HS 846390 (the code used for cold forming machine), 2025
In 2025, the largest exporter of HS 846390 (the code used for cold forming machine) in UN Comtrade data was China, with 29% of world exports; the largest importer in UN Comtrade data was the United States, with 14% 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).

Questions about cold forming machine
What is the HS code for Cold forming machine?
The HS code for Cold forming machine is 846390 (Machine-tools; for working metal, sintered metal carbides or cermets, without removing material, n.e.c. in heading no. 8463). The primary HS code for cold forming machines that do not remove material is 8463.90.
How do I classify Cold forming machine for customs?
Cold forming machine is classified under HS code 846390 — Machine-tools; for working metal, sintered metal carbides or cermets, without removing material, n.e.c. in heading no. 8463. This is a 6-digit subheading level code.
How does 8463 differ from 8462?
Heading 8462 is reserved for forging, stamping, and shearing machines, whereas 8463 covers other metalworking machines that do not remove material, such as those used for cold-working wire or tubes.
Which countries are the top exporters of cold forming machine (HS 846390)?
In 2025, the top exporters of HS 846390 (the code used for cold forming machine) in UN Comtrade data were China ($246M, 29% of world exports), Germany ($214M) and Italy ($75M). World exports came to about $840M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of cold forming machine (HS 846390)?
In 2025, the top importers of HS 846390 (the code used for cold forming machine) in UN Comtrade data were the United States ($110M, 14% of world imports), India ($74M) and China ($43M). World imports came to about $763M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Cold forming machine the same in all countries?
