Product classification

HS code for CNC drilling machine: 8459.21

Machine-tools, for drilling by removing metal, numerically controlled.

Classification of CNC drilling machine under HS 8459.21

HS code 845921 is assigned to machine-tools specifically designed for drilling operations by removing metal, and which are \"numerically controlled\" (CNC). This classification encompasses machines whose primary function is to create or enlarge holes in workpieces through the action of a rotating cutting tool, such as a drill bit. The \"numerically controlled\" aspect is critical, indicating that the machine's movements, tool changes, and operational parameters are precisely automated and managed by a computer program. This ensures high accuracy, repeatability, and efficiency in drilling processes. This code distinguishes advanced CNC drilling machines from conventional, manually operated drilling machines (which fall under 845929) and from multi-functional machines where drilling is not the sole or primary operation.

Codes often confused with 8459.21

Common mistake. A common misclassification occurs with HS 845929, which covers \"Other drilling machines (including those for boring, milling, or tapping by removing metal), not numerically controlled.\" The crucial differentiator is the \"numerically controlled\" feature; machines lacking this automation belong to 845929. Another potential confusion arises with HS 845931, which covers \"Boring-milling machines, numerically controlled.\" While drilling can be performed on boring-milling machines, 845921 is reserved for dedicated drilling machines where drilling is the primary and often sole metal-removing function, rather than a secondary operation within a broader machining process.

Top exporters and importers of HS 845921 (the code used for CNC drilling machine), 2025

In 2025, the largest exporter of HS 845921 (the code used for CNC drilling machine) in UN Comtrade data was China, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 11% 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).

Questions about CNC drilling machine

What is the HS code for CNC drilling machine?

The HS code for CNC drilling machine is 845921 (Machine-tools; for drilling by removing metal, numerically controlled). The HS code for a CNC drilling machine is 845921. This code specifically identifies numerically controlled machine-tools whose primary function is drilling by removing metal.

How do I classify CNC drilling machine for customs?

CNC drilling machine is classified under HS code 845921 — Machine-tools; for drilling by removing metal, numerically controlled. This is a 6-digit subheading level code.

What is the primary advantage of a CNC drilling machine over a conventional drilling machine?

The primary advantage of a CNC drilling machine is its superior precision, repeatability, and automation capabilities. CNC control allows for complex hole patterns, consistent depth control, and reduced human error, leading to higher quality parts and increased production efficiency compared to manual or conventional drilling machines.

Which countries are the top exporters of CNC drilling machine (HS 845921)?

In 2025, the top exporters of HS 845921 (the code used for CNC drilling machine) in UN Comtrade data were China ($69M, 20% of world exports), Italy ($67M) and Spain ($40M). World exports came to about $338M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Which countries are the top importers of CNC drilling machine (HS 845921)?

In 2025, the top importers of HS 845921 (the code used for CNC drilling machine) in UN Comtrade data were the United States ($29M, 11% of world imports), India ($22M) and Thailand ($17M). World imports came to about $273M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Is the HS code for CNC drilling machine the same in all countries?
