European industrial buyers are increasingly evaluating imported steel, aluminium and other CBAM-covered goods using total delivered cost rather than headline supplier prices. Under the EU Carbon Border Adjustment Mechanism (CBAM), a variable carbon-related obligation is added to other expenses, including freight, customs duties and financing. The approach links carbon costs to the overall import cost structure.
The assessment begins with the correct customs classification and the country of origin. Buyers then factor in purchase prices, logistics, and applicable steel import quotas or tariffs. They also account for eligible embedded emissions, benchmark-based deductions and recognised carbon prices paid abroad. The legal responsibility to account for CBAM certificates lies with the authorised EU declarant, though contracts may shift associated commercial costs to exporters or intermediaries.
Reference carbon price and how CBAM liability is calculated
The latest observable reference price for CBAM certificates is €82.32 per tonne of CO₂ equivalent for the third quarter of 2026, compared with €75.28 in the second quarter. This reference does not apply as a flat charge on every tonne of imported metal. The final liability depends on the product’s calculated embedded emissions and applicable deductions.
For illustration, if a shipment has a correctly calculated net certificate exposure equivalent to 0.5 tonnes of CO₂ per tonne of goods, the carbon cost at the third-quarter reference price would be €41.16 per tonne of goods. The calculation is presented as an example rather than an official emissions factor for a specific product or country of origin.
Supplier comparisons can change when a producer provides verified actual emissions data below the applicable Commission default values. Such evidence may help an exporter compete more effectively against a nominally cheaper supplier whose emissions data are insufficient. Claims of low-carbon production are not treated as a confirmed cost advantage without supporting installation-level evidence.
CBAM declaration schedule and cash-flow timing
CBAM obligations apply to imports made during 2026, while certificate purchasing begins in February 2027. The first CBAM declaration and certificate surrender are due by 30 September 2027. This creates a period between import activity and the point at which financial obligations are settled.
During that gap, buyers may have resold products or completed projects before the final cash outflow occurs. Procurement teams are therefore expected to coordinate with finance departments on cost accruals, guarantees and liquidity requirements. The timetable affects how import-related costs are planned and recorded internally.
Steel quota measure and shipment risk for affected products
The EU also applies a separate steel import quota measure that adds commercial risk for affected steel products. Tariff-free import volumes are reduced to approximately 18.3 million tonnes. Imports exceeding the applicable quota face a 50% duty, making shipment scheduling and quota entitlement critical.
A supplier discount that appears attractive at quotation stage can be reduced by customs restrictions and additional border costs. For buyers, this means that pricing comparisons may depend not only on supplier offers but also on quota access and customs outcomes tied to specific shipments.
Contract terms covering emissions data, verification and allocation
Procurement contracts are expected to specify who provides installation-level emissions data and which verification standards are acceptable. Contracts should also address how carbon-related costs are allocated across delivery quarters. They should include mechanisms for correcting errors in emissions information when they occur.
Where contractual arrangements allow, buyers can use verified emissions performance to support longer-term volume commitments and more predictable supplier relationships. This approach can reduce reliance exclusively on spot-price discounts for negotiations. Emissions evidence can then be relevant both for regulatory compliance and commercial discussions.
The practical advantage described relates to procurement organisations able to calculate carbon-adjusted delivered cost before placing orders. Under CBAM, emissions information functions as an input into supplier selection, pricing and financial planning rather than being treated solely as a compliance document gathered after shipment arrival.
