The EU’s Carbon Border Adjustment Mechanism is being strengthened in a way that affects carbon-accounting across parts of the metals chain, rather than treating mining extraction as the direct trigger. For Southeast Europe, the mechanism is described as a filter around value-creating steps including smelting, refining, alumina, aluminium, steel, ferroalloys, scrap use, electricity sourcing and downstream metal products. A mine producing ore or concentrate in Serbia, Bosnia and Herzegovina, Montenegro, North Macedonia or Albania is not automatically pulled into CBAM simply because it is a mine. A regional producer that converts mined material into steel, aluminium, ferronickel, processed metal inputs or EU-bound industrial components moves closer to the regulated perimeter.
The Council of the EU’s 12 June 2026 position sets out the direction of travel. CBAM has been fully operational since 1 January 2026 for iron and steel, cement, fertilisers, aluminium, electricity and hydrogen. The proposed strengthening would extend coverage to selected downstream products and close loopholes linked to circumvention and pre-consumer metal scrap. The Council also calls for an annual review by the Commission of further downstream products that could be included.
EU ETS coverage inside the bloc and CBAM exposure at the border
The policy shift matters for a region split between EU membership and non-EU status for customs and carbon pricing. Romania, Bulgaria, Greece, Croatia and Slovenia are inside the EU and operate within the EU ETS framework. Serbia, Montenegro, Bosnia and Herzegovina, North Macedonia and Albania remain outside EU customs and carbon-pricing arrangements while selling electricity, metals, components and industrial inputs into the EU market. CBAM creates an asymmetric pressure in which EU-based SEE producers face ETS costs directly while non-EU exporters face CBAM through their EU importers, customers and contract clauses.
The first pressure point described in the chain is not the mine gate but the first serious industrial conversion after extraction. In Serbia this includes copper mining linked with flotation, smelting and refining around Bor and Čukaru Peki. In Bosnia and Herzegovina it includes bauxite-related supply chains covering alumina, steel and ferroalloys. In Montenegro it points to legacy aluminium and bauxite industry assets alongside the country’s electricity balance and potential renewable supply base.
In North Macedonia, ferronickel processing is identified as relevant because it feeds stainless-steel value chains. Euronickel describes its Kavadarci operation as a nickel ore processing plant producing ferronickel for the stainless-steel industry. The company states that granules are roughly 20% nickel and 80% iron.
Serbia’s copper output figures and documentation requirements
Serbia is cited as an example of how CBAM can affect mining narratives without becoming a mining law. Zijin reports that its Bor Copper Mine and Čukaru Peki Copper-Gold Mine produced a combined 296,000 tonnes of copper and 9.1 tonnes of gold in 2025. Expansion is reported to target total copper output of 450,000 tonnes per year. Copper itself is not listed among current CBAM sectors.
The strategic issue for EU-facing supply chains is described as moving beyond whether Serbia can mine copper at scale. The next question becomes whether mined material can be documented through power use, smelting emissions, refinery performance, water and waste controls, product traceability and buyer-level emissions evidence. This same documentation logic is applied to other projects where processing steps connect to regulated value chains.
The same approach is referenced for Serbia’s Jadar lithium-boron project. The European Commission’s list of strategic projects outside the EU identifies Jadar as an extraction project in Serbia promoted by Rio Tinto via Rio Sava Exploration. The stated aim is to supply battery-grade lithium and metallurgy-grade boron. While this does not make lithium extraction a CBAM sector, it places Serbia within a wider raw-materials security architecture where bankability depends on traceability, environmental credibility, processing plans, power sourcing and downstream customer acceptance.
Aluminium and steel coverage tied to downstream goods
For aluminium and steel supply chains the exposure is described as more direct because CBAM already covers aluminium as well as iron and steel. The Council’s new position targets selected downstream goods due to a risk that carbon-intensive material could enter Europe as fabricated products rather than basic inputs. For Southeast Europe this translates into pressure on steelworks, rolling mills, aluminium processors, metal-fabrication exporters, construction-products suppliers and machinery-component producers. A Western Balkan company selling a steel-intensive or aluminium-intensive product into the EU may need both product code information and embedded emissions data for precursor materials.
The mechanism’s scope also extends through treatment of pre-consumer scrap used in recycling operations. The Council position supports measures bringing pre-consumer metal scrap into CBAM calculations while giving the Commission stronger tools against deceptive practices by high-risk companies. Exporters are expected to distinguish between post-consumer scrap, pre-consumer scrap, primary material and mixed feedstock with documentary precision. Scrap previously treated as a simple low-carbon input may become disputed when origin, classification or carbon allocation are weak.
Electricity imports subject to financial adjustment under CBAM
Electricity is identified as a second channel linking CBAM to mining-industry activities because regional assets are described as electricity-intensive. Aluminium production processes including ferroalloys, ferronickel routes as well as copper smelting depend on power cost and carbon intensity alongside beneficiation plants and refining systems. The Energy Community’s Q1 2026 CBAM Quarterly Report states that from 1 January 2026, electricity imports into the EU from non-EU countries including Energy Community Contracting Parties became subject to a financial adjustment intended to align carbon costs with the EU ETS.
The same report focuses on WB6 countries alongside neighbouring EU states while warning that CBAM-related electricity costs may alter cross-border trade and investment signals. Using the Commission’s Q1 2026 CBAM certificate price of €75.36/tCO₂e, default-based CBAM costs for electricity imports into the EU are calculated at around €86.51/MWh for Bosnia and Herzegovina. The calculations are also given as €78.45/MWh for Serbia, €73.78/MWh for Montenegro and €66.84/MWh for North Macedonia.
The report shows Albania at €0/MWh, attributed to its default electricity emissions factor. These figures are described as not being direct mining-sector charges but they affect regional power trading economics including renewable offtake value for industrial producers. The Energy Community also observes that in Q1 2026 there were widening spreads between WB6 electricity markets and EU member states along with reduced price correlation.
Diverging power systems inside Southeast Europe
This leads to a split described within Southeast Europe between hydro-heavy or renewable-backed systems versus coal-heavy systems in terms of commercial attractiveness for carbon-documented processing. Coal-heavy systems face a harder sell unless low-carbon electricity can be ring-fenced or carbon prices paid can be demonstrated alongside credible decarbonisation pathways. The Energy Community notes signs of short-term friction in market functioning during Q1 2026 with possible longer-term effects on investment signals and market integration.
For producers inside the EU SEE market segment CBAM operates alongside ETS exposure rather than replacing it entirely. Romania’s ALRO is described by the Aluminium Stewardship Initiative as one of Europe’s largest vertically integrated aluminium producers by capacity with 265,000 tonnes of primary aluminium capacity plus 340,000 tonnes of cast aluminium capacity in Slatina along with an alumina refinery in Tulcea. Greece’s Aluminium of Greece part of Metlen Energy & Metals states annual capacity above 190,000 tonnes of aluminium and 865,000 tonnes of alumina.
The source notes these assets sit inside the EU system but competitive positioning depends on how effectively CBAM prevents cheaper high-carbon imports entering through downstream loopholes. For non-EU Western Balkan producers the commercial challenge is described as more immediate because EU importers must declare embedded emissions while surrendering certificates based on CBAM rules.
CBAM declarations deadlines for importers from Western Balkans
The Commission’s framework requires importers to surrender certificates linked to declared embedded emissions while allowing deduction of carbon price already paid during production only where it can be proven. Importers must submit their first CBAM declaration together with surrender certificates by 30 September 2027, covering the first year of the definitive regime. A Western Balkan exporter unable to provide reliable actual emissions data may push its EU customer toward default values along with higher compliance risk and tougher contract terms.
This shift is framed around contract documentation requirements that extend beyond technical product acceptance for smelters refinery operators or metal fabricators in Southeast Europe. Buyers are expected to request installation-level emissions data precursor records batch-level traceability electricity source evidence metering data power-purchase documentation carbon-price-paid files scrap classification and verifier-ready reporting packs.
Cited financing implications linked to verified emissions reporting
Banks strategic investors and offtakers are described as beginning to assess SEE mining-and-metals projects through a CBAM lens even when mines themselves fall outside formal scope under current sector lists. A copper project with strong ore grades but weak disclosure on smelting energy may receive different commercial treatment compared with one showing renewable electricity alignment mass-balance controls and verified emissions reporting.
A ferronickel producer with clear electricity sourcing plus product-level documentation is described as better placed than a competitor relying on generic sustainability claims under buyer due diligence expectations tied to CBAM verification readiness. For bauxite or alumina chains connected to low-carbon power residue-management discipline and verified material flow the source indicates potential preference from EU buyers compared with alternatives described as cheaper but undocumented.
Southeast Europe’s opportunity is presented through its raw-material base industrial history grid interconnections and geographic proximity for supplying carbon-accounted metals and processed materials into the EU market. Examples listed include Serbia’s copper alongside lithium-boron potential; Bosnia’s bauxite-alumina supply chains together with steel legacy; Montenegro’s renewable-electricity potential alongside its aluminium footprint; North Macedonia’s ferronickel processing; Romania’s aluminium platform; and Greece’s integrated bauxite-alumina-aluminium chain.
The mechanism is described as rewarding producers able to prove what happens across stages including mine operations processing plants power metering smelters refineries scrap yards and delivery into EU customer requirements under CBAM verification processes.
