Product classification
HS code for CNC cylindrical grinder: 8460.23
Machine-tools, cylindrical grinding machines (excluding flat-surface and centreless), numerically controlled.
Classification of CNC cylindrical grinder under HS 8460.23
HS code 846023 is designated for machine-tools that perform cylindrical grinding operations and are \"numerically controlled\" (CNC). This classification specifically targets machines designed to remove material from the external or internal surfaces of cylindrical workpieces, where the workpiece is typically held between centers or in a chuck. The \"numerically controlled\" aspect signifies that the machine's movements, grinding parameters, and operational sequences are precisely managed by a computer program, ensuring high accuracy, repeatability, and automated production capabilities. The description explicitly excludes flat-surface and centreless grinding machines, thereby narrowing the scope to conventional cylindrical grinding applications. This precise definition aids in differentiating these advanced machines from other grinding technologies and non-CNC variants.

Codes often confused with 8460.23
Common mistake. A frequent misclassification involves HS 846022, which covers \"Machine-tools; grinding machines (excluding flat-surface), centreless, numerically controlled.\" The key distinction lies in the workpiece holding method: 846023 is for cylindrical grinders that typically use centers or chucks, while 846022 is for centreless grinders where the workpiece is supported differently. Another potential area of confusion is with HS 846024, a residual category for \"other\" numerically controlled grinding machines. However, 846023 is a more specific and appropriate classification for dedicated cylindrical grinders that are not centreless or flat-surface types.
Top exporters and importers of HS 846023 (the code used for CNC cylindrical grinder), 2025
In 2025, the largest exporter of HS 846023 (the code used for CNC cylindrical grinder) in UN Comtrade data was Germany, with 30% of world exports; the largest importer in UN Comtrade data was China, with 24% 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 cylindrical grinder
What is the HS code for CNC cylindrical grinder?
The HS code for CNC cylindrical grinder is 846023 (Machine-tools; cylindrical grinding machines (excluding flat-surface and centreless), numerically controlled). The HS code for a CNC cylindrical grinder is 846023. This code specifically covers numerically controlled machine-tools designed for cylindrical grinding operations, excluding flat-surface and centreless types.
How do I classify CNC cylindrical grinder for customs?
CNC cylindrical grinder is classified under HS code 846023 — Machine-tools; cylindrical grinding machines (excluding flat-surface and centreless), numerically controlled. This is a 6-digit subheading level code.
How does a cylindrical grinder differ from a surface grinder?
A cylindrical grinder is designed to process the external or internal surfaces of cylindrical workpieces, typically rotating the workpiece on its axis. In contrast, a surface grinder is used to produce flat, smooth surfaces on workpieces, usually by traversing the workpiece under a rotating grinding wheel. Their applications and operational principles are distinct.
Which countries are the top exporters of CNC cylindrical grinder (HS 846023)?
In 2025, the top exporters of HS 846023 (the code used for CNC cylindrical grinder) in UN Comtrade data were Germany ($265M, 30% of world exports), Switzerland ($193M) and Italy ($64M). World exports came to about $875M, 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 cylindrical grinder (HS 846023)?
In 2025, the top importers of HS 846023 (the code used for CNC cylindrical grinder) in UN Comtrade data were China ($182M, 24% of world imports), Germany ($118M) and the United States ($98M). World imports came to about $774M, 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.
