Numerically controlled panel benders

Subheading 846224 of the Combined Nomenclature covers numerically controlled (CNC) punching machines for metalworking. CNC punching machines are used to cut holes and shapes in metal sheets using a punch and die system, with the entire process being programmable and computer-controlled. These machines can produce series of holes in various shapes without manual tool changes. Subheading 846224 includes CNC turret punching machines, CNC punch presses with automatic tool changers, and combined CNC punching and nibbling machines. Classification is based on the Notes to Chapter 84 CN and heading 8462, which covers machine tools for working metal by forming. The key criterion distinguishing this subheading from 846229 is the presence of numerical control. Machines without CNC control are classified under separate subheadings. Classification follows the General Rules for the Interpretation of the CN, particularly Rules 1 and 6. Where classification is uncertain, importers should apply for Binding Tariff Information (BTI) ruling from the competent customs authority.

Importing CNC punching machines under subheading 846224 into the European Union is subject to the Union Customs Code (Regulation (EU) No 952/2013) and the Machinery Regulation (EU) 2023/1230, which replaced the Machinery Directive 2006/42/EC. Machines placed on the EU market must bear the CE marking, be accompanied by an EU declaration of conformity, and include operating instructions in the official language of the destination country. CNC punching machines are subject to harmonised European standards including EN ISO 11161 for safety of integrated manufacturing systems and EN ISO 16092 for safety of metal forming presses. Importers must hold an EORI number and submit a customs declaration through the appropriate import system. Import documentation includes the commercial invoice, technical specifications of the machine, transport documents, and proof of origin for preferential tariff rates. Machines containing electronic components are also subject to the EMC Directive 2014/30/EU and the Low Voltage Directive 2014/35/EU. Duty rates and trade measures should be verified in the TARIC database.

CNC punching machines under subheading 846224 are widely used in the metalworking, automotive, electronics, and construction industries. They are employed to manufacture components from steel, aluminium, and copper sheets, including enclosure panels, brackets, mounting plates, perforated sheets, and ventilation elements. CNC control enables rapid changeover and short-run production while maintaining high dimensional repeatability. Modern CNC turret punching machines can achieve speeds of several hundred strokes per minute, making them among the most productive sheet metal processing machines. For customs classification purposes, it is important to distinguish CNC punching machines from laser cutting machines (heading 8456) and from presses (subheadings 846242 to 846269). A punching machine operates by mechanically shearing material with a punch, while a laser uses thermal energy from a focused light beam. Correct classification requires analysis of the machine construction, operating principle, and technological function. Importers should have manufacturer technical documentation confirming the type of processing and the presence of CNC control.

CNC punching machines under CN 8462 24 are subject to stringent safety standards due to high pressing forces and crushing risks. Standards EN 692 (mechanical presses) and EN 693 (hydraulic presses) specify requirements for guards, two-hand control systems, light curtains and cycle monitoring. The Machinery Regulation (EU) 2023/1230 requires CE marking and risk assessment documentation. Presses exceeding 1000 kN force may be subject to dual-use controls for defence applications.
