HS code for Cylindrical grinder: 8460.29
Machine-tools, grinding machines (excluding flat-surface), other than numerically controlled.
Classification of cylindrical grinder under HS 8460.29
The classification of a cylindrical grinder under HS code 8460.29 is based on its function as a grinding machine that does not utilize a numerical control system and is not designed for flat-surface work. Heading 8460 includes various machine tools for finishing metal. Subheading 8460.2 covers grinding machines where the positioning in any one axis can be set to an accuracy of at least 0.01 mm. Within this group, a distinction is made between flat-surface grinders and "other" grinders. Cylindrical grinders, which are used to shape the outside or inside of an object (typically one that has a central axis of theoretical rotation), fall into the "other" category. Since 8460.29 is the residual category for non-numerically controlled grinding machines (excluding flat-surface), it is the correct designation for manual or semi-automatic cylindrical grinders. These machines are vital for producing precision shafts, bearings, and other round components. The classification must be carefully distinguished from 8460.22, which is the specific code for numerically controlled cylindrical grinding machines. To qualify for 8460.29, the machine must perform grinding operations where the workpiece is rotated against a grinding wheel. If the machine is used for sharpening specific tools like cutters, it would move to 8460.39. The distinction between "grinding" and "sharpening" is often based on the machine's design and intended application in a production environment versus a maintenance environment.

Codes often confused with 8460.29
Common mistake. Cylindrical grinders are frequently misclassified under 8460.22 if the importer assumes all precision grinders are numerically controlled. They are also sometimes confused with 8460.19, which is specifically for non-NC flat-surface grinders, or 8458.19 if the machine is mistaken for a lathe.
Top exporters and importers of HS 846029 (the code used for cylindrical grinder), 2025
In 2025, the largest exporter of HS 846029 (the code used for cylindrical grinder) in UN Comtrade data was China, with 17% of world exports; the largest importer in UN Comtrade data was India, with 27% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
