Product classification
HS code for CNC grinding machine: 8460.24
Machine-tools, grinding machines (excluding flat-surface, cylindrical and centreless), numerically controlled.
Classification of CNC grinding machine under HS 8460.24
CNC grinding machines are classified under HS code 8460.24 when they are numerically controlled and used for removing metal or cermets by means of grinding stones, abrasives, or polishing products. This specific code excludes flat-surface, cylindrical, and centreless grinding machines, which are covered by other subheadings within heading 8460. The classification is governed by Chapter 84, which includes machine tools for working metal. The "numerically controlled" (CNC) aspect is a critical factor in determining the subheading. These machines are used for precision finishing of workpieces, where high accuracy and repeatability are required. The technical specifications of the machine, such as the number of axes and the specific grinding method (e.g., internal grinding or tool and cutter grinding), must be reviewed to ensure they do not fall into the excluded categories. Under GRI 1, the machine is classified based on its function of grinding, and under GRI 6, it is placed in 8460.24 because it is CNC-operated but does not perform flat-surface or cylindrical grinding.

Codes often confused with 8460.24
Common mistake. This code is frequently confused with HS code 8460.12 (CNC flat-surface grinders) or 8460.22 (CNC cylindrical grinders). If the machine is not numerically controlled, it would fall under 8460.29. Furthermore, if the machine is a machining center capable of multiple functions beyond just grinding, it might be classified under 8457.10.
Top exporters and importers of HS 846024 (the code used for CNC grinding machine), 2025
In 2025, the largest exporter of HS 846024 (the code used for CNC grinding machine) in UN Comtrade data was Germany, with 24% of world exports; the largest importer in UN Comtrade data was China, with 39% 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 CNC grinding machine
What is the HS code for CNC grinding machine?
The HS code for CNC grinding machine is 846024 (Machine-tools; grinding machines (excluding flat-surface, cylindrical and centreless), numerically controlled). The HS code for a numerically controlled grinding machine (excluding flat-surface, cylindrical, and centreless) is 8460.24.
How do I classify CNC grinding machine for customs?
CNC grinding machine is classified under HS code 846024 — Machine-tools; grinding machines (excluding flat-surface, cylindrical and centreless), numerically controlled. This is a 6-digit subheading level code.
What if the CNC grinder is for flat surfaces?
If the CNC grinding machine is specifically designed for flat-surface grinding, it should be classified under HS code 8460.12.
Which countries are the top exporters of CNC grinding machine (HS 846024)?
In 2025, the top exporters of HS 846024 (the code used for CNC grinding machine) in UN Comtrade data were Germany ($162M, 24% of world exports), Japan ($157M) and China ($65M). World exports came to about $663M, 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 CNC grinding machine (HS 846024)?
In 2025, the top importers of HS 846024 (the code used for CNC grinding machine) in UN Comtrade data were China ($212M, 39% of world imports), the United States ($52M) and India ($36M). World imports came to about $541M, 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.
