HS Code 8460.22 – Machine-tools; grinding machines (excluding flat-surface), centreless, numerically controlled
HS code 8460.22 is the 6-digit subheading for machine-tools, grinding machines (excluding flat-surface), centreless, numerically controlled. It is used for CNC centerless grinder, thru-feed centerless grinder, in-feed centerless grinder, multi-axis centerless grinder and automated centerless grinding system.
What HS 8460.22 covers
This category encompasses numerically controlled (NC or CNC) centerless grinding machines, excluding those for flat surfaces. These advanced machine tools are designed for high-volume, high-precision grinding of cylindrical parts without the need for center support, making them ideal for components like bearings, shafts, and pins. Industries such as automotive, aerospace, and medical device manufacturing heavily rely on these machines for their efficiency, accuracy, and repeatability. Importers are typically large-scale manufacturers and specialized component producers, while exporters are countries at the forefront of machine tool technology, offering sophisticated automation and control systems.

Codes often confused with 8460.22
Common mistake. Often confused with 846029 (other non-CNC grinding machines) if the 'numerically controlled' aspect is overlooked, or with 846023 (CNC cylindrical grinders) if the 'centerless' feature isn't distinguished.
Top exporters and importers of HS code 846022, 2025
In 2025, the largest exporter of HS code 846022 in UN Comtrade data was Switzerland, with 18% of world exports; the largest importer in UN Comtrade data was China, with 19% 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).
