Bosnia and Herzegovina’s exporters face uncertainty over costs under the European Union’s definitive Carbon Border Adjustment Mechanism (CBAM), which applies to covered imports from 1 January 2026. The first annual declarations and certificate surrender are due by 30 September 2027, and EU buyers may pass costs or emissions-data requirements back to Bosnian suppliers through commercial contracts.
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. That price is a reference, not an automatic charge of 82.32 euros on every tonne of imported steel, aluminium or cement.
Actual liabilities depend on the embedded emissions attributed to covered goods, applicable free-allocation adjustments 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. No publicly established aggregate estimate of Bosnia and Herzegovina’s overall CBAM exposure was identified.
The issue returned to national attention on 31 October as industrial exporters faced the financial implications of moving from emissions reporting to carbon-linked import liabilities. That coverage did not establish a new national tax, an EU exemption decision or a quantified financial liability for Bosnian industry.
2026 imports settle in 2027
Financial exposure relates to covered imports made during 2026, even though the first annual settlement takes place the following year. CBAM certificates for 2026 imports will first be available for purchase in February 2027, with the corresponding annual declarations and certificate surrender due by 30 September 2027.
The formal obligation generally rests with the authorised EU importer or its responsible indirect customs representative, rather than the Bosnian exporter. However, buyers may seek to allocate costs through revised purchasing contracts or price adjustments, and require suppliers to provide emissions data. The commercial allocation of CBAM costs can therefore affect suppliers before the first settlement.
Bosnia and Herzegovina’s steel, aluminium, cement and electricity sectors are particularly exposed because they supply industrial and energy markets in the EU. The EU has an annual 50-tonne exemption for specified covered goods, including metals, cement and fertilisers, but it does not apply to electricity or hydrogen.
Emissions data and electricity evidence
For steel and aluminium producers, competitiveness increasingly depends on credible installation-level emissions information, identifying relevant production routes and supporting use of actual emissions where permitted. The European Commission framework allows verified actual emissions or applicable default values, but more favourable treatment based on actual emissions requires compliance with regulatory evidence requirements.
For imported electricity, CBAM exposure can be calculated using default emissions factors unless conditions for actual emissions are met. Actual emissions require documented evidence linking generation to 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.
These requirements concern traders and renewable generators operating across Bosnia and Herzegovina, Croatia, Montenegro and Serbia, particularly where contracted electricity sales are intended for EU markets. The same commercial questions affect the wider Western Balkans, where industrial producers compete for EU customers while operating with different domestic energy mixes and carbon-pricing arrangements.
Commercial and financing exposure
Unverified emissions, incomplete product classification, uncertain contractual allocation of costs and inadequate coordination with European declarants are among the commercial issues for Bosnian exporters. They could affect export pricing, customer retention and working-capital needs. European buyers may increasingly differentiate suppliers according to documented emissions exposure and the reliability of 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. The immediate task for businesses is to prepare defensible emissions calculations, verified export documentation and workable contracts before the first financial settlement in 2027.
