Product classification
HS code for Tool grinder: 8460.39
Machine-tools, sharpening (tool or cutter grinding) machines, other than numerically controlled.
Classification of tool grinder under HS 8460.39
The HS code 8460.39 applies to tool grinders that are not numerically controlled. This classification falls under Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8460 specifically addresses machine-tools for deburring, sharpening, grinding, honing, lapping, polishing, or otherwise finishing metal or cermets. The subheading 8460.39 is reserved for sharpening (tool or cutter grinding) machines that do not utilize a computer numerical control (CNC) system. These machines are essential in workshops for maintaining the edge of cutting tools used in other machining processes. The classification is driven by the primary function of the machine—sharpening—and the absence of automated numerical control. If the machine were designed for grinding surfaces rather than sharpening tools, it might fall under different subheadings of 8460, such as 8460.12 or 8460.22. The distinction between sharpening and general grinding is critical for correct tariff application, as sharpening machines are specialized for restoring the geometry of cutting edges on drills, cutters, and lathe tools.

Codes often confused with 8460.39
Common mistake. The most common misclassification is with HS code 8460.31, which is for numerically controlled (CNC) sharpening machines. Importers often fail to distinguish between manual and automated versions. Additionally, hand-held electric grinders are classified under 8467.23, as they are tools for working in the hand rather than stationary machine tools.

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).
