A Turkish extrusion and finishing plant could serve EU buyers from Serbia. The case works on customer proximity, conversion skill and low-carbon material — not on disguising the emissions in imported billet.
The investment case is plausible, not yet a project
There is no verified current announcement of a large new Turkish aluminium-processing platform in Serbia on which to perform project due diligence. The useful exercise is therefore an investment case: whether a Turkish producer should locate extrusion, finishing and machining in Serbia for automotive, building, solar and industrial customers in the EU. Historic investor discussions are not an operating plant.
Türkiye has scale in downstream aluminium but depends heavily on imported primary metal. Its industry produced about 1.92mn tonnes in 2023 and exported products worth roughly $5.3bn, while sector sources estimate that about 95 per cent of primary aluminium is imported. Serbia already receives Turkish alloyed unwrought aluminium — 4,023 tonnes worth $11.3mn in 2024 — and has its own downstream benchmark in MTC/NISSAL, which reports extrusion, anodising and powder-coating capacities.
Serbia offers lower-cost industrial locations, engineering labour, road and rail access to central Europe, a free-trade relationship with the EU under the Stabilisation and Association Agreement, and proximity to vehicle and component plants. It also introduces border formalities, non-EU regulatory status, a carbon-intensive power mix and a smaller labour pool. Moving one processing step across the border is not automatically an advantage.
The plant creates value if it changes the product. It destroys value if its business plan assumes Serbia changes the carbon history of the metal.
An illustrative 20,000–25,000 tonne plant
A credible mid-sized model would use one or two extrusion presses with billet handling and heat treatment, plus powder coating or anodising, machining, dies, laboratory and scrap systems. An editorial benchmark puts fixed investment at €40mn–€60mn: €7mn–€10mn for land, building and utilities; €14mn–€20mn for presses and heat treatment; €8mn–€12mn for finishing; €4mn–€7mn for machining, dies and quality systems; and €7mn–€11mn for wastewater, scrap handling, energy measures, contingency and initial working capital.
Those ranges are scenario assumptions, not vendor quotations. Site conditions, press size, automation, automotive certification and whether anodising is included can move them substantially. Working capital is especially important because billet is normally the largest cash item and follows the London Metal Exchange plus regional premiums. At high utilisation, a €50mn plant may look modest; at 50 per cent utilisation, depreciation, labour and energy turn the same asset into an expensive warehouse.
Illustrative conversion opex excluding billet is about €450–€800 a tonne: €70–€150 for energy, €90–€160 for direct and indirect labour, €140–€250 for dies, chemicals, consumables and maintenance, and €100–€180 for logistics, quality, administration and other costs. Billet can represent 70–80 per cent of total cash cost. Buyer contracts, metal-price pass-through, scrap credit and 70 per cent-plus utilisation therefore matter more than a small wage or tax advantage.
CBAM follows emissions, not the factory sign
The EU’s Carbon Border Adjustment Mechanism entered its definitive regime on 1 January 2026. Authorised EU importers must account for embedded emissions in covered aluminium and surrender certificates linked to the EU Emissions Trading System price, subject to the phase-in and applicable thresholds. A carbon price already paid in the origin country can be recognised under the rules. Reporting methods and verified actual data determine the liability; unsupported claims can force conservative defaults.
Processing Turkish or third-country billet in Serbia does not reset its embedded emissions. CBAM calculations carry relevant precursor emissions into the downstream product. Nor does a Serbian certificate of origin automatically follow from repacking or minimal work: EU preferential access requires sufficient transformation under the applicable rules of origin. A genuine extrusion and finishing operation can meet those rules; a routing warehouse cannot.
Serbia’s electricity mix adds a second issue. Direct emissions in aluminium production are central to current CBAM accounting, while indirect-emissions treatment can evolve and EU buyers already include electricity in supplier Scope 2 assessments. A coal-heavy grid can weaken a bid even where the formal 2026 certificate calculation is limited. The plant needs traceable low-carbon or recycled billet, verified product footprints and a credible renewable power contract.
The decision turns on buyers, not incentives
The strongest model is contract-led. A Turkish investor should first secure multi-year nominations from EU automotive, solar, transport or building-system customers requiring just-in-time delivery, machining and certified finishing. Serbia then shortens the route, reduces finished-goods inventory and places engineers near customers. The plant should be designed around alloys, tolerances and surface treatment those buyers have approved, not a generic capacity target.
The weak model relies on state aid, cheaper labour and an assumption that CBAM can be arbitraged through Serbian origin. Incentives can improve a viable return but cannot compensate for high-carbon billet, low utilisation or rejected quality. A primary smelter would be a different order of capex and electricity demand and is not the rational entry case. Remelt and recycling capacity may be attractive later if scrap supply, permits and clean energy can be secured.
Serbia can be a useful EU-facing base for Turkish aluminium processing, particularly for complex profiles whose conversion value exceeds the border cost. The investability conditions are clear: €40mn–€60mn of disciplined capex, contracted volume above the utilisation threshold, LME pass-through, auditable precursor emissions, genuine Serbian transformation and low-carbon power. That is a manufacturing strategy. Anything less is a customs theory likely to fail at the buyer’s compliance desk.
