HS Code 84.63 – Machine-tools; n.e.c. for working metal, sintered metal carbides or cermets without removing material
What HS 84.63 covers
Heading 8463 serves as the residual 'basket' category for machine-tools designed to work metal, sintered metal carbides, or cermets *without removing material*, and which are *not elsewhere specified* (n.e.c.) within Chapter 84, particularly not in heading 8462. This classification covers a diverse range of specialized processes that manipulate metal through methods other than the explicit forming operations listed in 8462 (like forging, bending, punching, shearing). It includes operations such as thread rolling, wire drawing, tube drawing, spinning, riveting, and spring-making. The core principle is that the material's shape or properties are altered without significant material loss. This heading is crucial for classifying highly specialized or niche metalworking equipment that doesn't fit into the more common categories of metal cutting or conventional forming. Accurate classification under 8463 ensures correct tariff application and compliance with specific trade regulations, especially for unique industrial machinery. These machines are vital in specialized manufacturing sectors, including fastener production, wire and cable manufacturing, and spring production, where precise, non-cutting metal manipulation is required.
- Covers
Thread rolling machines, Wire drawing machines, Tube drawing machines, Spinning machines (metal), Riveting machines, Spring-making machines, Coiling machines (for metal wire/strip), Cold forming machines (not covered by 8462), Stretch forming machines (if not bending/flattening), Automatic assembly machines for metal parts (if primary function is joining/forming without removal), Metal powder compacting presses (if not covered by 8462), Electromagnetic forming machines, Orbital riveting machines, Rotary swaging machines, Expanders for tubes, Metal forming machines using high-energy-rate techniques (e.g., explosive forming, if not covered by 8462), Tube reducing machines, Straightening machines for wire, Nail making machines, Chain making machines
- Examples
A Swiss manufacturer exports high-speed wire drawing machines to a cable producer in India for manufacturing electrical conductors, leveraging established sea freight routes. A US company imports specialized thread rolling machines from Taiwan for mass-producing fasteners for the automotive industry, typically via trans-Pacific shipping. An Italian company exports CNC tube spinning machines to a French aerospace contractor for producing complex hollow components, benefiting from efficient intra-EU logistics.

Codes often confused with 84.63
Common mistake. Misclassification under 8463 frequently occurs by confusing it with 8462 (metal forming machines), especially when the operation involves shaping metal without explicit material removal but isn't one of the specific processes listed in 8462 (e.g., thread rolling vs. bending). Another common error is classifying general industrial machinery (8479) here if the 'machine-tool' aspect for working metal is overlooked. Crucially, it must be 'without removing material' to differentiate from 8458-8461. The key is working metal without material removal, and not being specifically covered by 8462's defined forming operations.
Top exporters and importers of HS code 8463, 2025
In 2025, the largest exporter of HS code 8463 in UN Comtrade data was China, with 32% 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).
