Product classification
HS code for CNC pipe bender: 8462.51
Machine-tools, for working tube, pipe, hollow section and bar (excluding presses), for working metal, numerically controlled.
Classification of CNC pipe bender under HS 8462.51
The CNC pipe bender falls under HS code 8462.51. This classification is specific to machine tools used for working tubes, pipes, hollow sections, and bars, specifically those that are numerically controlled. Unlike machines that process flat sheets, which fall under the 8462.2x or 8462.3x series, the 8462.5x series is dedicated to three-dimensional profiles and solid bars. The bending process involves applying mechanical force to change the geometry of the pipe or tube without collapsing its internal structure. The "numerically controlled" (CNC) designation indicates that the machine uses a digital system to control the bending angles, rotation, and feed length, which is essential for complex automotive or aerospace components. The classification is determined by the physical characteristics of the workpiece (tubes/pipes) and the automated nature of the control system, as per the requirements of heading 8462 and subheading 8462.51. This ensures that specialized pipe-working machinery is distinguished from general sheet metal bending equipment.

Codes often confused with 8462.51
Common mistake. CNC pipe benders are often misclassified under 8462.22, which is the code for CNC bending, folding, or flattening machines. However, 8462.22 is strictly for machines that work on flat products (sheet metal). Another common error is using 8462.59, which is the code for pipe benders that are not numerically controlled. It is vital to identify the input material; if the machine works on wire rather than pipe or bar, it may fall under 8463.30.
Top exporters and importers of HS 846251 (the code used for CNC pipe bender), 2025
In 2025, the largest exporter of HS 846251 (the code used for CNC pipe bender) in UN Comtrade data was China, with 26% of world exports; the largest importer in UN Comtrade data was the United States, with 21% 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 pipe bender
What is the HS code for CNC pipe bender?
The HS code for CNC pipe bender is 846251 (Machine-tools; for working tube, pipe, hollow section and bar (excluding presses), for working metal, numerically controlled). The HS code for a numerically controlled machine tool for bending tubes, pipes, or bars is 8462.51.
How do I classify CNC pipe bender for customs?
CNC pipe bender is classified under HS code 846251 — Machine-tools; for working tube, pipe, hollow section and bar (excluding presses), for working metal, numerically controlled. This is a 6-digit subheading level code.
Can this code be used for manual pipe benders?
No, manual or non-CNC pipe bending machines are classified under HS code 8462.59.
Which countries are the top exporters of CNC pipe bender (HS 846251)?
In 2025, the top exporters of HS 846251 (the code used for CNC pipe bender) in UN Comtrade data were China ($77M, 26% of world exports), Italy ($72M) and the Netherlands ($61M). World exports came to about $292M, 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 pipe bender (HS 846251)?
In 2025, the top importers of HS 846251 (the code used for CNC pipe bender) in UN Comtrade data were the United States ($57M, 21% of world imports), Mexico ($32M) and China ($14M). World imports came to about $270M, 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.
