HS Code 8463.90 – Machine-tools; for working metal, sintered metal carbides or cermets, without removing material, n.e.c. in heading no. 8463
HS code 8463.90 is the 6-digit subheading for machine-tools, for working metal, sintered metal carbides or cermets, without removing material, n.e.c. in heading no. 8463. It is used for cold heading machines, riveting machines, metal spinning machines, roll forming machines (for profiles) and orbital riveting machines.
What HS 8463.90 covers
This is a residual HS code for metalworking machine tools that operate without removing material, but are not specifically classified as draw-benches (846310), thread rolling machines (846320), or wire working machines (846330). This broad category can include machines for cold heading, riveting, metal spinning, roll forming, or other specialized forming processes. Trade in these machines often caters to niche manufacturing requirements, supporting industries that need specific deformation processes for metal components, such as fastener production, aerospace, or specialized fabrication. Exporters and importers are typically countries with diverse industrial bases.

Codes often confused with 8463.90
Common mistake. As an 'n.e.c.' code, it's frequently misclassified with more specific metal forming machines under 8462 (e.g., presses) or even other non-material-removing machines within 8463 if the specific function isn't clearly defined.
Top exporters and importers of HS code 846390, 2025
In 2025, the largest exporter of HS code 846390 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).
