Serbian and Montenegrin exporters may qualify for lower carbon border charges on goods entering the United Kingdom from January 2027, following the inclusion of their domestic carbon pricing arrangements on a provisional list published by British tax authorities.
HM Revenue & Customs (HMRC) released the list of potentially recognised carbon pricing systems on 27 August 2026, identifying Serbia’s Carbon Tax and Montenegro’s Emissions Trading Scheme among the arrangements that could qualify for relief under the UK’s forthcoming Carbon Border Adjustment Mechanism (CBAM).
The list also includes carbon pricing arrangements in China, India, Japan, South Korea, Kazakhstan and Canada, alongside several other international markets. The development is relevant to suppliers of steel, aluminium, cement, fertilisers and hydrogen serving British customers.
Eligibility depends on carbon costs actually paid
Under the UK CBAM framework, importers may claim relief when embedded emissions in imported goods have already been subject to an eligible carbon price outside the United Kingdom. However, recognition of a national carbon pricing system does not automatically establish an exporter’s eligibility for a reduction.
Importers must provide evidence demonstrating the effective carbon cost associated with the relevant embedded emissions. The presence of a domestic tax or emissions trading scheme alone is insufficient to establish that the carbon cost qualifies for relief.
The amount eligible for recognition may also be reduced or eliminated by free allowances, rebates and compensation arrangements. Consequently, the actual financial benefit will depend on the carbon payments attributable to the emissions associated with the imported goods.
Verification and documentation requirements
The UK framework places additional emphasis on emissions documentation and independent verification. Companies must provide appropriate evidence from the relevant production installation or supply chain, supported by an independent verification process that meets the applicable standards.
For Serbian manufacturers, the potential benefit is concentrated in export-oriented industrial production rather than electricity exports, which are excluded from the initial scope of the UK CBAM. Montenegrin suppliers face comparable requirements where their industrial emissions are covered by qualifying domestic carbon pricing arrangements.
The ability to establish the carbon price actually paid and link it to the embedded emissions of exported products will therefore be central to demonstrating eligibility for relief.
Separate compliance requirements for UK and EU markets
Recognition under the British framework does not automatically confer equivalent treatment under the EU Carbon Border Adjustment Mechanism. Serbian and Montenegrin exporters supplying both markets must account for the differences between the two systems when assessing their carbon-related liabilities.
Companies may consequently need to prepare separate compliance calculations for British and EU customers, using a common set of industrial emissions monitoring records where appropriate. Maintaining consistent installation-level data could support both reporting processes while allowing exporters to demonstrate compliance with the requirements of each jurisdiction.
Carbon pricing evidence enters industrial financing assessments
The potential reduction in border charges could also affect financial assessments of industrial exporters. For banks financing companies exposed to the UK market, the ability to demonstrate eligible carbon payments may become relevant to revenue forecasts and credit assessments.
Exporters able to document qualifying carbon costs may be better positioned to negotiate competitive supply contracts than companies unable to provide reliable evidence. The commercial value of the provisional UK recognition will ultimately depend on the domestic carbon payments made by Serbian and Montenegrin producers and their ability to substantiate those payments under the British framework.
