The window for shaping the future of British trade is closing in a matter of hours. Today, March 24, 2026, at 23:59, the UK government will officially conclude its public consultation on the secondary legislation for the UK Carbon Border Tax (CBAM). This is the final opportunity for importers, trade bodies, and global manufacturers to provide feedback on the administrative “engine room” of a policy that will redefine the cost of importing carbon-intensive goods into the UK starting January 1, 2027.
While the primary law is already set, this technical consultation focuses on the day-to-day reality for businesses. Key areas under review include the mandatory registration process for importers, the frequency and format of filing CBAM returns, and the rigorous record-keeping requirements. For industries dealing in steel, aluminium, cement, fertilisers, hydrogen, and iron, the UK Carbon Border Tax represents a significant shift in operational overhead. Getting the administrative rules right now is the difference between a streamlined digital filing process and a bureaucratic logjam when the 2027 deadline hits.
European and global exporters to the UK are watching this deadline with particular intensity. The UK’s version of the carbon border tax is designed to mirror (though not perfectly replicate) the EU’s CBAM, aiming to prevent “carbon leakage” while ensuring British industries remain competitive. If your business moves heavy industrial goods across the UK border, today’s midnight deadline is your last chance to influence how your reimbursement claims will be handled and how your data will be audited. The consultation portal at gov.uk remains open for submissions until the final minute of the day.
