The European Union’s Carbon Border Adjustment Mechanism (CBAM) is moving beyond basic carbon-intensive commodities and toward a wider range of downstream industrial products, according to a new European Parliament compromise amendment addressing the expansion of its scope and anti-circumvention measures.
The proposed changes would extend CBAM attention to manufactured goods containing carbon-intensive inputs such as steel, aluminium, copper and other industrial materials, covering products across sectors including fabricated metals, machinery, electrical equipment and transport components.
The amendment is linked to proposal 2025/0419(COD), which would amend Regulation (EU) 2023/956 regarding the extension of CBAM coverage to downstream goods and measures designed to prevent circumvention. Although the document does not represent final legislation, it signals a broader regulatory direction: the EU is seeking to track embedded emissions not only in raw materials but also in finished and semi-finished industrial products entering the European market.
CBAM moves from raw materials toward manufactured products
The expansion focuses on preventing companies from avoiding carbon obligations by processing regulated materials into higher-value products before exporting them to the EU. Under the proposed approach, carbon exposure would no longer be assessed only at the stage of basic materials production. Instead, regulators would examine how emissions embedded in metals and industrial inputs move through supply chains into finished goods.
The amendment provides a detailed CN-code-based product inventory, assigning relevant greenhouse gases, including primarily carbon dioxide, along with nitrous oxide for nitrogen fertiliser products and perfluorocarbons across multiple metal-related categories. The approach would make customs classification increasingly important for determining carbon compliance obligations.
Steel products face broader compliance requirements
One of the largest areas affected is Chapter 73, covering articles made from iron and steel. The proposed coverage extends beyond semi-finished steel products and includes a wide range of manufactured goods such as containers, wire products, cables, ropes, slings, fencing materials, chains, anchors, nails, springs, stoves, air heaters, household articles, sinks, cast products and grinding balls.
These categories cover products used in construction, industrial maintenance, mining applications, household manufacturing and fabricated metal industries. For exporters, the change would mean CBAM relevance could depend not only on whether a company produces steel but also whether its finished goods contain regulated materials and fall under listed customs classifications.
Aluminium supply chains face expanded carbon tracking
The amendment also includes extensive coverage of Chapter 76 aluminium products. Listed categories include unwrought aluminium, powders, bars, rods, profiles, wire, plates, sheets, strips, foil, tubes, pipe fittings, aluminium structures, tanks, containers, cans, compressed-gas containers, cables, tableware and sanitary products.
The expansion is particularly significant for aluminium because production emissions vary widely depending on the electricity source used during manufacturing.
Aluminium produced using coal-based electricity can have a substantially different carbon profile from aluminium produced using hydropower, nuclear-backed electricity or documented renewable energy supplies. For manufacturers in regions supplying EU markets, including the Western Balkans, Turkey and North Africa, aluminium profiles and structures are important components in construction systems, façades, windows, doors, technical structures and industrial equipment. Buyers may increasingly require embedded-emissions information, supplier declarations, electricity documentation and traceability from raw materials through final products.
Machinery and industrial equipment enter CBAM discussions
The proposed expansion extends into a broad range of Chapter 84 machinery products, creating implications for industrial equipment suppliers.
Covered categories include steam and vapour boilers, boiler equipment, turbines, engines, pumps, compressors, air-conditioning and refrigeration systems, heat exchangers, filters, dishwashers, spraying equipment, fire extinguishers, cranes, forklifts, conveyors, construction machinery, agricultural machinery, machine tools, moulding equipment, valves, bearings, transmission shafts, gears and gearboxes. The inclusion of machinery would move carbon reporting closer to industrial procurement decisions.
Equipment such as boilers, turbines, compressors, cranes, conveyors, valves and heat exchangers are often supplied as part of larger engineering, procurement and construction (EPC) packages, industrial upgrades, energy projects, mining operations and infrastructure developments.
As a result, buyers may increasingly evaluate not only equipment specifications and commercial terms but also the embedded emissions associated with metal content and the quality of supplier emissions monitoring systems.
Electrical equipment and infrastructure components included
The amendment also covers a range of electrical equipment products, including electric motors, generators, generating sets, transformers, static converters, inductors, transformer components, ferrite cores, steel laminations, stator and rotor cores, electrical panels and switchgear.
The inclusion has implications for power infrastructure projects because electrical equipment can carry embedded carbon even when used in low-carbon developments. Renewable energy projects, battery facilities and industrial power systems may require carbon documentation for equipment such as transformers, switchgear, steel structures, aluminium cable systems and generator components. Future procurement processes may therefore consider not only whether a project produces low-carbon energy but also the emissions profile of the equipment used to build it.
Transport components face new carbon documentation demands
Transport-related products represent another significant category in the proposed expansion. The amendment includes products such as railway equipment, rolling stock parts, tractors, passenger vehicles, commercial vehicles, special-purpose vehicles, vehicle bodies, gearboxes, axles, suspension components, radiators, steering systems, bicycles, trailers and aircraft parts.
For automotive suppliers in countries connected to EU manufacturing networks, including Serbia, Bosnia and Herzegovina, North Macedonia and Turkey, the development could increase demand for detailed carbon information. Manufacturers supplying EU automotive companies may need emissions documentation alongside existing quality and production records, particularly as buyers seek greater visibility into supply-chain emissions.
Smaller manufacturers face higher reporting demands
The compliance impact is expected to vary between companies. Large exporters with established procurement systems, energy monitoring, enterprise software and EU customer relationships may be better positioned to meet new requirements. Smaller manufacturers producing goods such as aluminium windows, steel tanks, machine components or electrical cabinets may face greater challenges because they may lack systems capable of calculating emissions at the individual product level. The proposed CBAM expansion requires companies not only to measure emissions but also to allocate, verify and transmit carbon data according to EU requirements.
Exporters prepare for product mapping and emissions tracking
Companies affected by the expansion would need to begin with CN-code mapping, reviewing product catalogues against proposed CBAM classifications. Many businesses may discover that products such as industrial valves, fittings, transformer parts, machine components and prefabricated structures fall within covered categories despite not traditionally identifying as steel or aluminium producers.
The next step involves bill-of-materials tracking, allowing companies to identify materials used in each product, supplier sources and associated embedded emissions. Electricity documentation will also become increasingly important for industries involving metal processing, machining, welding, heat treatment and industrial assembly. Companies using renewable electricity contracts, direct supply agreements or other documented energy arrangements would need to connect those records with production sites, meters and manufacturing periods.
Western Balkan manufacturers face closer EU supply-chain integration
The proposed CBAM expansion is particularly relevant for the Western Balkans, where many companies participate in EU industrial supply chains through processed metals, components, machinery, automotive parts, electrical equipment and construction products. Although many regional producers remain outside the EU Emissions Trading System, downstream CBAM expansion would increase regulatory alignment with EU markets.
Manufacturers across the region may face greater requirements for emissions reporting, including companies involved in industrial production in locations such as Belgrade, Čačak, Kragujevac, Niš, Novi Sad, Skopje and Sarajevo. The immediate commercial challenge is not only potential carbon costs but also the ability to provide reliable emissions information demanded by EU customers.
Financial institutions monitor CBAM exposure
Banks and investors are also expected to assess how companies exporting CBAM-covered goods manage regulatory risks. Industrial businesses may need investment in energy monitoring systems, efficiency improvements, renewable electricity procurement, emissions databases and supplier verification processes.
Companies with structured CBAM preparation strategies may demonstrate stronger resilience compared with manufacturers that treat carbon reporting only as a customs requirement. The proposed expansion also creates opportunities for producers able to combine lower-carbon operations with transparent emissions data. CBAM readiness increasingly depends on factory-level systems linking product classification, material flows, electricity use, production records, supplier declarations and export documentation.
The proposed inclusion of downstream industrial goods indicates that the EU’s carbon border policy is evolving from a mechanism focused on selected commodities into a broader framework for tracking embedded emissions across industrial supply chains.
