Carbon accounting is moving deeper into the steel supply chain as Europe’s decarbonisation efforts increase the commercial importance of emissions from iron ore processing, direct reduced iron (DRI) and alloy production. For suppliers selling into the EU, product quality and benchmark prices remain essential, but verified carbon intensity is becoming another factor in how industrial buyers assess feedstock costs.
The Carbon Border Adjustment Mechanism (CBAM) reaches beyond finished steel products. Agglomerated iron ores and concentrates classified under CN 2601 12 00, including iron ore pellets, are covered, alongside pig iron, DRI and most of the iron and steel chain. Carbon exposure can therefore arise at the pellet-production stage rather than only when finished coils, beams or pipes cross the EU border.
This upstream coverage matters as European steelmakers develop production routes combining higher-grade iron ore, natural-gas- or hydrogen-based DRI and electric furnaces. Traditional blast-furnace production relies heavily on coke and coal, while newer routes seek to reduce emissions through different feedstocks, fuels and processing technologies. Competition for suitable iron ore and lower-emission intermediate products is consequently becoming more important.
Iron ore quality increasingly intersects with carbon intensity
Iron content, impurities and particle-size distribution remain central to iron ore purchasing, but the emissions associated with processing and downstream use can also affect the economics of a shipment. Lower-grade ore may require additional beneficiation or greater reductant consumption later in the production chain, potentially increasing the overall carbon burden.
By contrast, high-grade pellets produced using efficient equipment, lower-carbon electricity and lower-emission fuels may offer an advantage where emissions influence the cost of imported materials. The commercial distinction increasingly involves both the physical properties of the feedstock and the ability to substantiate its production footprint.
For pellet producers outside the EU, this creates a choice between relying on applicable CBAM default values and developing monitoring, reporting and verification systems that support actual emissions data.
Under the definitive CBAM rules described for iron and steel, default values are subject to mark-ups rising from 10% in 2026 to 20% in 2027 and 30% from 2028 onward. Where a producer’s verified actual emissions are materially below the applicable default, reliable documentation can improve the carbon-cost position of its product.
Imported DRI and hot-briquetted iron gain strategic importance
Direct reduced iron occupies a distinct position in the steel transition because it is both an intermediate steelmaking material and an alternative to conventional blast-furnace iron. As Europe develops additional electric steelmaking capacity, domestic DRI production may be constrained by the availability and cost of natural gas and low-carbon hydrogen.
Imports of DRI and hot-briquetted iron (HBI) can therefore form part of the feedstock mix for European mills. Under CBAM, purchasing decisions must account not only for price and metallisation but also for emissions at the producing installation and the energy system supplying it.
Pig iron presents a related procurement challenge. Conventional blast-furnace routes generally have a higher carbon burden than DRI production using low-carbon energy. Once embedded emissions and the associated CBAM certificate requirement are reflected in the comparison, a lower headline price for pig iron may not translate into a lower carbon-adjusted cost.
These differences make the production route an increasingly important part of the commercial specification for imported iron units.
Ferroalloy coverage creates different carbon-cost exposures
The CBAM treatment of ferroalloys is selective rather than uniform. Ferromanganese, ferrochrome and ferronickel are covered through the iron and steel chapter, exposing major third-country smelting operations to the mechanism.
These alloys can require substantial electricity and reductants. Their emissions profiles depend on factors including the electricity source, furnace efficiency, ore grade, reductant consumption and process design. Producers using lower-carbon electricity may consequently have a different carbon-adjusted position from competitors relying on more emissions-intensive power.
Ferrochrome is particularly relevant to stainless-steel production. Europe relies heavily on imported chromium units and external ferrochrome production, making the carbon intensity of overseas smelting an additional consideration for procurement teams.
Buyers that have traditionally compared alloy benchmark prices and freight costs may also need installation-specific emissions information to evaluate the total cost of supply under CBAM.
Ferronickel and refined nickel face different border treatment
Ferronickel illustrates how customs classification and production stage can determine CBAM exposure. Ferronickel is covered, while refined nickel classified under Chapter 75 is generally outside the current CBAM scope.
As a result, materials serving related stainless-steel and nickel value chains can receive different border-carbon treatment depending on how they are classified and where they sit in the production chain.
The current exclusions extend to ferro-silicon, ferro-silico-manganese, ferro-silico-chromium, ferromolybdenum, ferro-tungsten, ferrovanadium, ferroniobium and several other ferroalloys not included in the current iron-and-steel list. The mechanism therefore does not apply a consistent carbon adjustment to all alloying materials.
For trading companies handling covered and uncovered alloys from the same supplier portfolio, this distinction creates a need for precise classification and shipment-level documentation. Traders need to establish which installation produced each consignment, whether its emissions have been verified, whether a carbon price has already been paid in the country of origin, and how the relevant evidence reaches the EU importer.
Traceability becomes part of feedstock contracting
For steelmakers, the consequences extend beyond customs administration. The choice of pellets, DRI and ferroalloys can affect the final steel product’s emissions intensity, the commercial case for green-steel premiums and the ability to meet customers’ product-footprint requirements.
Securing lower-emission inputs can strengthen a mill’s emissions position before the material reaches the melting stage. This increases the potential value of supply arrangements that combine reliable feedstock volumes with documented emissions performance.
Multi-year offtake agreements may become more relevant for some materials than anonymous spot-market purchases. Producers developing lower-carbon pellet or DRI capacity may seek long-term contracts with European mills that value both supply security and traceable emissions data.
Contracts can establish requirements for data sharing, verification rights, emissions methodologies, changes in law and the allocation of CBAM-related costs. Such provisions help define how carbon information and financial exposure move through the supply chain.
Energy availability influences investment geography
The economics of pelletisation, DRI and ferroalloy production are also linked to where suitable resources and energy supplies are available. Regions with abundant renewable electricity, access to natural gas, low-carbon hydrogen potential or high-grade ore may be better positioned to develop these activities.
Potentially advantaged locations include parts of Scandinavia, the Middle East, North Africa and Canada, alongside other markets with low-carbon power. Conversely, coal-intensive production hubs may face greater pressure as emissions become more relevant to the cost of supplying European customers.
The relative attractiveness of these locations depends on more than carbon intensity. Feedstock access, energy availability, production costs, logistics and the ability to deliver material that meets industrial specifications remain part of the investment calculation.
Scrap availability links DRI demand to carbon economics
Europe’s scrap market is another part of the changing raw-material balance. Electric furnaces can use high proportions of recycled ferrous material, reducing the requirement for primary iron units, but substitution is limited by scrap quality, residual elements and available volumes.
High-quality DRI and HBI can supplement scrap-based steelmaking as cleaner iron units that help manage feedstock quality. Their value is therefore linked not only to iron ore and gas prices but also to scrap spreads and carbon-related costs.
For lenders financing pellet plants, DRI facilities or ferroalloy projects, this creates a broader set of variables to test. Financial scenarios need to consider electricity carbon intensity, EU ETS and CBAM exposure, default-value mark-ups, verification expenses, logistics, natural gas or hydrogen availability and the premium available for lower-emission feedstock.
The commercial role of carbon data now extends across mines, concentrators, pellet plants, DRI modules and ferroalloy furnaces, alongside the blast furnaces and electric arc furnaces where steel is produced. The ability to document emissions at these upstream stages is becoming a factor in how suppliers compete for European steelmaking demand.
