Subheading 8479 81 of the Combined Nomenclature covers machines and mechanical appliances for treating metals or cermets, having individual functions, not specified or included elsewhere in Chapter 84. This subheading includes specialised machines for plastic deformation, forming, shaping and finishing of metals that do not fall within headings 8456-8466 covering machine tools. Examples include wire straightening machines, tubeless tube forming machines, mechanical coating devices for metals and other machines with specific metalworking functions. Classification requires analysis of whether the machine is covered by more specific headings for machine tools, presses or rolling mills. The General Rules for Interpretation (GRI), particularly Rules 1 and 6, form the basis for classification. In case of doubt, a Binding Tariff Information (BTI) ruling from the competent customs authority is recommended.

Importing metal treating machines under subheading 8479 81 into the European Union requires compliance with the Union Customs Code (Regulation (EU) No 952/2013). The importer must hold an EORI number and submit an electronic customs declaration with the correct CN code. Machines are subject to the Machinery Regulation (EU) 2023/1230, requiring conformity assessment, technical documentation and CE marking. The manufacturer or authorised representative in the EU must issue an EU declaration of conformity. Metal treating machines may constitute dual-use items under Regulation (EU) 2021/821 if they enable precision processing at levels required in the defence or nuclear sector. The importer should verify the dual-use status before import. Documentation includes a commercial invoice, transport document, technical specification and operating instructions in an EU language. Duty rates should be verified in the European Commission's TARIC database.

MFN duty rates for metal treating machines under subheading 8479 81 should be verified in the current European Commission TARIC database. Preferential duty rates may be available under EU FTAs, including CETA, the EU-Japan EPA, the EU-South Korea Agreement and the EU-UK TCA. Compliance with rules of origin and valid proof of origin (EUR.1, invoice declaration or REX) are required for preferential treatment. Specialised machines may benefit from autonomous tariff suspensions if they are not produced in the EU in sufficient quantity. Imports from Russia and Belarus are subject to EU sanctions, including bans on the export and import of selected technologies. Metal treating machines from China may be subject to anti-dumping measures, which should be verified in TARIC. VAT at the applicable national rate applies on import. The importer should check all customs and tax charges in TARIC before filing a customs declaration.
