Bosnia and Herzegovina’s exporters face uncertainty over the cost of the European Union’s Carbon Border Adjustment Mechanism (CBAM), which applies to covered imports from 1 January 2026. The European Commission set the CBAM certificate reference price at 82.32 euros per tonne of CO2 equivalent for the third quarter of 2026, up from 75.28 euros per tonne in the second quarter. The reference price is not an automatic charge of that amount on every tonne of imported steel, aluminium or cement.
Actual liabilities depend on the embedded emissions attributed to covered goods, adjustments for applicable free allocation under the EU Emissions Trading System (EU ETS), eligible deductions for carbon prices paid in the country of origin and the number of certificates ultimately required. Although the formal obligation generally falls on an authorised EU importer or its responsible indirect customs representative, buyers may pass costs to Bosnian suppliers through contract changes or price adjustments.
2026 imports will be settled in 2027
Financial exposure relates to covered goods imported during 2026, even though the first annual settlement takes place the following year. CBAM certificates covering 2026 imports will first be available for purchase in February 2027, and the first annual declarations and corresponding certificate surrender are due by 30 September 2027.
EU buyers may also require suppliers to provide emissions data, making the allocation of CBAM costs a commercial issue before settlement. Steel, aluminium, cement and electricity producers in Bosnia and Herzegovina are particularly exposed because they supply EU industrial and energy markets.
On 31 October, preparedness returned to national attention as industrial exporters faced uncertainty over the financial consequences of moving from emissions reporting to carbon-linked import liabilities. Zdravko Marinković is president of the Foreign Trade Chamber of Bosnia and Herzegovina. The 31 October coverage did not establish a new national tax, an EU exemption decision or a quantified liability for Bosnian industry, and no publicly established aggregate estimate of the country’s overall CBAM exposure was identified.
Emissions evidence affects supplier treatment
For steel and aluminium producers, competitiveness increasingly depends on credible installation-level emissions information, identifying relevant production routes and supporting the use of actual emissions where permitted. The European Commission’s framework allows verified actual emissions or applicable default values; actual-emissions treatment requires regulatory evidence.
For imported electricity, exposure can be calculated using default emissions factors unless conditions for actual emissions are met. Evidence must document the link between generation and physical electricity delivery, supported by contractual arrangements, metering, transmission-system information and other regulatory records. A renewable power purchase agreement or guarantee of origin alone does not establish eligibility to use actual emissions.
These requirements affect traders and renewable generators operating across Bosnia and Herzegovina, Croatia, Montenegro and Serbia, particularly when contracted electricity sales are intended for EU markets. The EU has an annual 50-tonne exemption for specified covered goods, including metals, cement and fertilisers, but the threshold does not apply to electricity or hydrogen.
Contracts and financing carry the exposure
Commercial issues for Bosnian exporters include unverified emissions, incomplete product classification, uncertain contractual allocation of CBAM costs and inadequate coordination with European declarants. These issues could affect export pricing, customer retention and working-capital needs. European buyers may increasingly differentiate suppliers based on documented emissions exposure and reliable compliance data.
Banks financing Bosnian exporters must account for the possibility that CBAM-related costs are deducted from sales revenues, passed through to suppliers or included in revised customer pricing. Similar commercial questions affect the Western Balkans, where industrial producers compete for EU customers while operating with different domestic energy mixes and carbon-pricing arrangements.
The immediate task for Bosnian businesses is to prepare defensible emissions calculations, verified export documentation and commercially workable contracts before the first financial settlement in 2027.
