Goods entering the European Union before being re-exported to the United Kingdom could be subject to carbon-border assessments in both jurisdictions once the UK mechanism begins, although the two assessments do not automatically result in two full carbon payments.
The issue is particularly relevant for EU-to-UK supply chains in which goods move through separate customs and carbon-pricing systems before reaching their final destination. Carbon Pulse reported an expert warning about this potential overlap on 22 September.
The UK framework provides for relief where the embedded emissions of imported goods have already been subject to a qualifying carbon-pricing arrangement. HM Revenue & Customs identifies potential qualifying arrangements including a carbon tax, an emissions trading system or a mechanism that prices emissions embodied in imported goods.
UK relief depends on supporting evidence
The availability of relief is conditional on the importer providing the required independently verified carbon-pricing form and information supporting the relevant calculation.
A carbon payment made earlier in the supply chain does not, by itself, establish the amount that a UK importer can deduct. The prescribed evidence must support the relief claim.
This creates a particular documentation challenge for distributors and other intermediaries. The company responsible for the UK declaration may not be the producer of the goods or the business that incurred the earlier carbon-related obligation.
Information supporting the earlier carbon treatment therefore needs to move through the supply chain together with the commercial and customs documentation required for the UK declaration.
Carbon assessment and final payment are separate issues
The possibility of two carbon-border assessments should be distinguished from the amount ultimately payable.
Two jurisdictions can assess emissions associated with the same goods, while an applicable and properly documented relief can reduce the second jurisdiction’s liability. Conversely, evidence that carbon costs were already paid elsewhere may not be sufficient if it does not meet the requirements for the prescribed relief.
The distinction will become relevant for companies structuring EU-to-UK distribution arrangements and calculating potential border carbon costs.
Supply contracts may need clearer allocation of responsibilities
Companies may need their supply arrangements to specify who obtains verification, who provides supporting records and who bears the financial consequences if a relief claim cannot be substantiated.
The potential exposure is therefore not that every re-export from the EU to the UK will automatically result in two full carbon payments. The operational risk is that a deduction available under the UK framework may not be claimable because the evidence required to support it does not reach the importer responsible for the declaration.
