Product classification
HS code for Centerless grinder: 8460.29
Machine-tools, grinding machines (excluding flat-surface), other than numerically controlled.
Classification of centerless grinder under HS 8460.29
Centerless grinders are classified under HS code 8460.29. This code falls under Chapter 84, which includes machine tools. Heading 8460 covers machine-tools for deburring, sharpening, grinding, honing, lapping, polishing, or otherwise finishing metal or cermets by means of grinding wheels, abrasives, or polishing products. Subheading 8460.29 is used for grinding machines where the positioning in any one axis cannot be set to an accuracy of at least 0.01 mm, or more commonly, for machines that are not numerically controlled (non-CNC). Centerless grinding is a specific process where the workpiece is supported by a work-rest blade and held between a regulating wheel and a grinding wheel. This classification is specific to machines that finish metal surfaces and are operated manually or via mechanical cams rather than computer programs. The classification follows GRI 1 and 6, focusing on the machine's function and its lack of numerical control.

Codes often confused with 8460.29
Common mistake. The most common misclassification is 8460.22, which is reserved for numerically controlled (CNC) centerless grinders. Importers must verify if the machine has a CNC unit. Another error is using 8460.19, which is for flat-surface grinding machines; centerless grinders are for cylindrical or shaped workpieces and do not fall under flat-surface categories.

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).
