European industrial buyers are increasingly assessing imported steel, aluminium and other CBAM-covered goods on the basis of total delivered cost rather than headline supplier prices. The EU Carbon Border Adjustment Mechanism (CBAM) adds a variable carbon-related obligation to other expenses, including freight, customs duties and financing.
The calculation starts with the correct customs classification and country of origin. Buyers must then account for purchase prices, logistics, applicable steel import quotas or tariffs, eligible embedded emissions, benchmark-based deductions and recognised carbon prices paid abroad. The legal obligation to account for CBAM certificates rests with the authorised EU declarant, although contracts may transfer the associated commercial costs to exporters or intermediaries.
Carbon prices reshape supplier comparisons
The latest observable reference price for CBAM certificates is €82.32 per tonne of CO₂ equivalent for the third quarter of 2026, up from €75.28 in the second quarter. This reference does not represent a flat charge of €82.32 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. This is an illustrative calculation, not an official emissions factor for a particular product or country of origin.
Supplier rankings can change when one producer provides verified actual emissions data below the applicable Commission default values. Such evidence may allow the exporter to compete more effectively against a nominally cheaper supplier whose emissions data are insufficient. By contrast, claims of low-carbon production cannot safely be treated as a confirmed cost advantage without supporting installation-level evidence.
Certificate timing creates financial planning challenges
CBAM obligations apply to imports made during 2026, but certificate purchasing begins in February 2027. The first CBAM declaration and certificate surrender are due by 30 September 2027.
This timetable creates a gap between importing goods and meeting the resulting financial obligations. Buyers may have resold products or completed projects before the final cash outflow occurs, making it important for procurement teams to coordinate with finance departments on cost accruals, guarantees and liquidity requirements.
The EU’s separate steel import quota measure introduces another layer of commercial risk. The reduction in tariff-free import volumes to approximately 18.3 million tonnes, combined with a 50% duty on imports exceeding the applicable quota, makes shipment scheduling and quota entitlement critical for affected steel products. A supplier discount that appears attractive at the quotation stage can be eroded by customs restrictions and additional border costs.
Contracts must reflect emissions and delivery risks
Procurement contracts should specify who is responsible for supplying installation-level emissions data, which verification standards are acceptable, how carbon-related costs are allocated across delivery quarters and how errors in emissions information will be corrected.
Where contractual arrangements allow, buyers can use verified emissions performance to support longer-term volume commitments and more predictable supplier relationships, rather than relying exclusively on spot-price discounts. Such arrangements make emissions evidence relevant to commercial negotiations as well as regulatory compliance.
The emerging advantage will belong to procurement organisations capable of calculating carbon-adjusted delivered cost before placing orders. Under CBAM, emissions information is becoming a direct input into supplier selection, pricing and financial planning, rather than simply another compliance document collected after a shipment arrives.
