European steel market signals in the first half of 2026 point to intensifying cross-border competition at the same time that carbon accounting is becoming more operational for exporters. EUROFER data show Chinese steel imports up 40% year on year and Indonesian shipments up 70%, while total EU steel imports fell by 5%. Türkiye stayed the EU’s largest supplier of finished steel as Serbian exporters dealt with weaker demand and a new EU steel trade measure introduced in July.
For Serbian metals firms, the price paid at the EU border is increasingly shaped by more than factory-gate costs. Import tariffs, customs requirements and CBAM liabilities all affect the final delivered cost to European customers. As carbon reporting requirements become a larger share of commercial planning, emissions documentation is moving closer to day-to-day contracting decisions rather than remaining a compliance-only exercise.
The interaction between trade frictions and carbon pricing is also visible in how exporters manage shipment-by-shipment risk. CBAM obligations depend on how goods are classified for customs purposes and which product-specific rules apply. In practice, operating in steel or aluminium does not automatically mean every exported item falls within CBAM scope, making correct classification a prerequisite for cost forecasting.
Serbia’s industrial base spans integrated steelmaking and downstream metal processing, alongside aluminium production and transformation. HBIS Serbia operates integrated works in Smederevo, while producers and processors include Metalfer Steel Mill. On aluminium, Impol Seval is part of a wider chain that also includes companies turning rolled metal into industrial products for further use in European supply chains.
Within steel, carbon liability is tied to the production route and the specific characteristics of the exported product. The mechanism’s cost drivers include product category, precursor inputs and verified direct embedded emissions. Where European customers rely on applicable default values, their calculated costs may differ from cases where material is supported by validated, installation-specific emissions data.
CBAM certificate reference pricing adds another layer to planning for exporters and their buyers. The third-quarter 2026 CBAM certificate reference price is €82.32 per tonne of CO₂ equivalent, which makes accurate emissions calculations important for commercial schedules. A generic carbon surcharge cannot reflect differences between products, production facilities or the calculation rules that apply to each case.
Trade measures are also creating immediate cost exposure alongside carbon-related charges. Serbian steel exporters must account for an EU annual duty-free import quota of approximately 18.3 million tonnes and a 50% out-of-quota duty for relevant steel categories. The impact on an individual shipment depends on country and product allocations, customs origin and remaining quota capacity.
This means tariff outcomes can shift shipment costs more quickly than changes in quarterly CBAM reference pricing. Exporters and European customers therefore need to evaluate tariff exposure and carbon liabilities separately when structuring orders. Preferential tariff eligibility does not by itself determine CBAM obligations, so compliance planning cannot be reduced to checking whether a shipment qualifies for reduced duties.
Aluminium faces different emissions accounting mechanics compared with steel, even when it is traded under similar commercial conditions. Aluminium production is particularly exposed to electricity costs, but indirect emissions from purchased electricity are not automatically included in the current CBAM charge for aluminium. Direct process emissions, upstream inputs covered by applicable rules and correct product classification remain central to determining carbon liability.
The distinction matters for factories that market products as low-carbon while purchasing renewable electricity. Electricity procurement alone does not establish the emissions value used for CBAM calculations under the mechanism’s specific accounting framework. Serbian aluminium exporters therefore need to separate information used for broader environmental claims from the data required under CBAM rules.
Beyond current coverage, planned policy changes could widen compliance obligations for metal-intensive finished goods. The proposed extension of CBAM to selected downstream products from 2028 would potentially bring some manufactured goods into scope while other products are already covered. The final list remains subject to EU negotiations following amendments supported by the European Parliament in September 2026.
Until scope details are settled, manufacturers need to assess exposure against applicable rules on a product-by-product basis rather than assume uniform treatment across downstream categories. This approach reflects how customs classification and rule applicability determine whether CBAM applies and how costs are calculated for each item exported into the EU market.
Across both steel and aluminium supply chains, traceable emissions data are becoming a commercial requirement tied to documentation quality. A reliable compliance record needs to connect material origin, production-facility information, emissions calculations and allocation of products to EU customers. Accurate documentation and verification can help buyers distinguish between suppliers and calculate their obligations more precisely.
Taken together, rising Asian import volumes into the EU alongside tightening carbon reporting requirements increase pressure on Serbian exporters to manage both trade-cost variables and emissions-related calculations with precision. With quota capacity influencing near-term import costs and CBAM certificate reference pricing affecting emissions-based planning, compliance evidence increasingly shapes how buyers evaluate suppliers within European supply chains. The combined effect points to a market where access depends on tariff outcomes, correct customs classification and validated emissions data rather than pricing alone.
