Product classification
HS code for CNC boring machine: 8459.41
Machine-tools, for boring by removing metal, numerically controlled boring machines, n.e.c. in heading 8459.
Classification of CNC boring machine under HS 8459.41
A CNC boring machine is classified under HS code 845941. This classification specifically applies to numerically controlled machine-tools designed for boring operations by removing metal. The "numerically controlled" aspect signifies that the machine's movements and operations are automated and precisely guided by computer programming, enabling high accuracy and repeatability in manufacturing processes. The phrase "n.e.c. in heading 8459" (not elsewhere specified or included) indicates that this subheading covers general-purpose CNC boring machines that do not fall into more specific categories within heading 8459, such as boring-milling machines. This code is therefore appropriate for dedicated CNC boring machines used for enlarging or finishing existing holes in metal workpieces.

Codes often confused with 8459.41
Common mistake. Common misclassification for CNC boring machines can occur with other metal-working machine-tools. For instance, non-numerically controlled boring machines are classified under HS code 845949. Machines that combine both boring and milling functions, known as boring-milling machines, are classified under HS code 845931 if numerically controlled, or 845939 if not. Drilling machines, which create holes rather than enlarge or finish them, are found under 845921 (numerically controlled) or 845929 (other). Milling machines, dedicated to removing metal using rotary cutters, are classified under 845951 (numerically controlled) or 845959 (other). The key distinction for 845941 is the sole or primary function of boring and the presence of numerical control, without significant milling capabilities.
Top exporters and importers of HS 845941 (the code used for CNC boring machine), 2025
In 2025, the largest exporter of HS 845941 (the code used for CNC boring machine) in UN Comtrade data was China, with 32% of world exports; the largest importer in UN Comtrade data was China, with 34% 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).
