Numerically controlled roll forming machines

Subheading 846225 of the Combined Nomenclature covers numerically controlled (CNC) roll forming machines designed for shaping metals by plastic deformation. CNC roll forming machines use rotating rolls to bend, profile, and shape metal sheets, with roll parameters controlled by a computer programme. This subheading includes three-roll and four-roll CNC plate bending machines, CNC roll forming lines, and CNC tube and closed-profile forming machines. Classification is based on the Notes to Chapter 84 CN and heading 8462, which covers machine tools for working metal by forming. The essential classification criterion is the presence of numerical computer control. Roll forming machines without CNC control are classified under separate subheadings of heading 8462. Subheading 846225 should be distinguished from rolling mills under heading 8455, which cover metallurgical rolling equipment for processing ingots and billets. Classification follows the General Rules for the Interpretation of the CN. Where there is doubt, importers should apply for Binding Tariff Information ruling from the competent customs authority.

Importing CNC roll forming machines under subheading 846225 into the European Union is governed by the Union Customs Code (Regulation (EU) No 952/2013) and the Machinery Regulation (EU) 2023/1230. Each machine placed on the EU market must carry the CE marking, be accompanied by an EU declaration of conformity, and include complete operating instructions in the official language of the destination country. Roll forming machines are subject to harmonised standards EN 13985 and the EN ISO 16092 series concerning the safety of presses and forming machine tools. Importers must hold an active EORI number and file a customs declaration in the import system. Import documentation includes the commercial invoice, machine technical specifications describing the CNC control, transport documents (CMR, B/L, or AWB), and proof of origin for preferential tariff rates. CNC roll forming machines containing electronic components are subject to the EMC Directive 2014/30/EU. Duty rates and any applicable trade measures should be verified in the current TARIC database of the European Commission before each import.

CNC roll forming machines under subheading 846225 are used in the metalworking, construction, energy, and shipbuilding industries. They serve to manufacture welded tubes, pressure vessels, closed profiles, cylindrical and conical elements, and insulation cladding. CNC control enables precise programming of bending radius, roll rotation speed, and clamping force, allowing production of geometrically complex components with high repeatability. For customs classification, it is essential to distinguish roll forming machines under subheading 846225 from metallurgical rolling mills under heading 8455, which process ingots and billets by hot or cold rolling. Machines under subheading 846225 process finished sheet metal, forming it through plastic deformation. Correct classification requires analysis of the machine's technological function and verification of its control type. Modern CNC roll forming machines may be equipped with real-time measurement systems that monitor the shape during production. Importers should hold manufacturer technical documentation confirming the machine parameters and intended application to support customs classification.

CNC roll forming machines under CN 8462 25 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.
