Starting in January 2027, UK importers in sectors like steel and aluminium must prepare for a new compliance regime under the Carbon Border Adjustment Mechanism, demanding detailed record-keeping and registration, with small businesses needing to act swiftly.
UK importers in sectors such as steel, aluminium, cement, fertiliser and hydrogen will soon face a new layer of compliance as the Carbon Border Adjustment Mechanism comes into force on 1 January 2027. The scheme is designed to curb carbon leakage by placing a carbon price on certain imported goods so they are treated more comparably to products made in the UK.
For many businesses, the most immediate obligation will not be payment of the tax itself but the need to keep detailed records from day one. HMRC expects importers of in-scope goods to retain those records for six years, and failures could lead to penalties. That means companies need to know well in advance whether their imports fall within the regime and what evidence they will need to hold.
The government says the policy is aimed at supporting the UK’s wider decarbonisation strategy and helping to ensure that emissions are not simply shifted overseas into jurisdictions with weaker carbon pricing. It is also part of the country’s path towards net zero by 2050. In practice, that puts CBAM alongside similar border measures already shaping international trade, and it has become a point of discussion in negotiations with trading partners, including India.
One detail likely to catch smaller firms out is that outsourcing customs paperwork does not necessarily remove responsibility. Even where a customs broker, freight forwarder, haulier or tax agent completes the import declaration, the business may still be treated as the importer and remain liable for CBAM obligations. For SMEs, that makes it especially important to check who legally holds the duty, rather than assuming the agent carries the risk.
Registration for the scheme opens on 1 January 2028. Businesses will need to register with HMRC if the value of their CBAM goods imported over the previous 12 months exceeds £50,000, or if they expect to go above that level within the next 30 days. That threshold is low enough to bring in many smaller manufacturers, builders’ merchants, fabricators and construction firms, not just larger industrial groups.
Once registered, businesses will have to file a return even if no tax is due, and any liability for the 2027 accounting period must be settled by 31 May 2028. HMRC says further guidance on rates, default emissions values and emissions monitoring, reporting and verification will follow.
The timing could prove challenging for smaller importers already stretched by wider sustainability reporting demands. With only months to prepare, the practical advice is straightforward: check whether your goods are in scope, establish whether you or your agent counts as the importer, and put record-keeping systems in place before 2027 begins. For businesses that rely on imported materials, the paperwork burden may arrive long before the bill does.

- https://www.gov.uk/government/collections/carbon-border-adjustment-mechanism – The UK government has introduced the Carbon Border Adjustment Mechanism (CBAM), effective from 1 January 2027, to impose a carbon price on specified goods imported into the UK from sectors at risk of carbon leakage, including aluminium, cement, fertiliser, hydrogen, and iron and steel. This mechanism aims to ensure that imported goods face a comparable carbon price to that paid by UK manufacturers, thereby supporting the UK’s decarbonisation efforts and preventing the displacement of carbon emissions overseas. Businesses importing these goods must comply with CBAM requirements, including record-keeping and potential registration with HMRC.

The mechanism aims to impose a carbon price on these imports, ensuring they face a comparable carbon price to that paid by UK manufacturers. This policy is part of the UK’s broader strategy to achieve net-zero emissions by 2050 and to prevent the displacement of carbon emissions to countries with less stringent carbon pricing.
