HS Code 8460.24 – Machine-tools; grinding machines (excluding flat-surface, cylindrical and centreless), numerically controlled
HS code 8460.24 is the 6-digit subheading for machine-tools, grinding machines (excluding flat-surface, cylindrical and centreless), numerically controlled. It is used for CNC gear grinder, CNC thread grinder, CNC cam grinder, CNC spline grinder and CNC form grinder.
What HS 8460.24 covers
This category includes numerically controlled grinding machines that are not specifically designed for flat-surface, cylindrical, or centerless applications. It serves as a broad classification for highly specialized CNC grinders, such as gear grinders, thread grinders, cam grinders, and jig grinders, which produce complex geometries with extreme precision. These machines are vital for industries requiring intricate and high-tolerance components, including automotive, aerospace, mold making, and precision tooling. Importers are typically advanced manufacturing facilities seeking specialized solutions for unique grinding challenges, while exporters are often niche manufacturers from technologically advanced economies.

Codes often confused with 8460.24
Common mistake. This 'other' category can be confused with more specific CNC grinding codes like 846022 or 846023 if the machine has some cylindrical elements but its primary function is specialized, or with 846029 (other non-CNC grinding machines) if the CNC aspect is overlooked.
Top exporters and importers of HS code 846024, 2025
In 2025, the largest exporter of HS code 846024 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).
