The UK government has published its first illustrative Carbon Border Adjustment Mechanism rates, giving importers an early look at charges that could apply from January 2027. The figures are based on a Q3 2026 average UK ETS price of £58.15 per tonne of CO2e. Aluminium shows the highest illustrative rate at £9.79/tCO2e, with iron and steel close behind at £9.69/tCO2e, after accounting for free allowances still available to domestic producers. These are not final tax rates. The first official CBAM rates for Q1 2027 are due before the end of 2026, followed by quarterly updates. The illustrative numbers mainly help importers understand how the UK ETS price and free allowance status feed into the border charge. Importers of covered goods should use the next few months to check product codes, gather emissions data from suppliers, and stress-test what happens if the UK ETS price moves. The gov.uk page includes a worked example, which is worth reading before the final rates are set.

Useful to finally see numbers, even if they're labelled illustrative. Aluminium at £9.79/tCO2e and steel at £9.69/tCO2e look low against the £58.15 UK ETS price, but the gap is mostly free allowances still going to domestic producers. The real test comes when those start falling.

The free allowance adjustment is the mechanism to watch. The UK ETS price only translates into a CBAM charge after subtracting what domestic industry doesn't pay. If free allowances phase out faster than expected, the import rate climbs even without any change in carbon price. Importers should model both variables now.

Worth reading the gov.uk worked example too. The headline rate depends on emissions assumptions and the ETS price, so a supplier with cleaner production should end up paying less than the illustrative figure. The quarterly updates will show how much that distinction actually moves the charge.

One practical question: does the calculation treat electricity used in production as embedded emissions? If it does, the grid carbon factor in the country of origin swings the bill more than the UK ETS price does. That would make supplier-specific data matter a lot more than the sector averages in this announcement.

Fastener importers shouldn't assume this only hits bulk steel and aluminium. If nuts, bolts, and fixings fall under the iron and steel CBAM category, the charge lands on components too. The practical move is checking product codes against the full goods list before the final Q1 2027 rates come out.
