The EU’s Carbon Border Adjustment Mechanism (CBAM) extends carbon-accounting requirements into the steel supply chain before crude steel production begins. Under the current framework, agglomerated iron ore pellets are covered goods classified under CN code 2601 12 00. This brings upstream emissions data and verification into procurement decisions for integrated steelmakers and their suppliers.
The European Commission has confirmed that iron ore pellets under CN code 2601 12 00 fall within CBAM. It also states that agglomerated iron ore is among the categories for which indirect emissions are relevant under the current methodology. For pellet producers, mining groups, commodity traders and EU importers, the implications extend beyond metallurgical quality.
Upstream pellet emissions and precursor rules in CBAM calculations
Pellet sources with comparable production performance can have different embedded-emissions values and different levels of data reliability. These differences can affect the emissions attributed to downstream steel products. The CBAM approach also links upstream information to downstream reporting when pellets are used as precursors in complex goods.
When pellets are treated as precursors, their embedded emissions can feed into downstream calculations in line with applicable precursor rules. Carbon accounting therefore extends beyond the steelmaking installation itself. It can depend on information originating at upstream production facilities.
Pellet quality has traditionally influenced blast-furnace productivity and fuel consumption. Under CBAM, sourcing decisions also incorporate an emissions-data dimension. A steelmaker may receive pellets with similar metallurgical characteristics but different embedded-carbon values.
If reliable precursor information is not available, a downstream producer may need to use default values. This can apply even when its own installation maintains strong emissions-monitoring systems. The methodology thus creates a dependency on upstream documentation for accurate reporting.
Verified precursor data, defaults and procurement recordkeeping
Integrated steelmakers are expected to evaluate raw materials at product and process level rather than relying only on corporate-average emissions targets. The applicable CBAM methodology determines which emissions reductions affect the statutory calculation and which improvements fall under broader product-footprint assessment. Procurement decisions therefore need to reflect verified precursor emissions.
Where actual values are used, procurement teams should record the pellet-producing installation, country of origin, CN code, quantity, reporting period and verified emissions value. The downstream verifier must be able to confirm that upstream verification documentation corresponds to the precursor consumed in the relevant production process. This traceability requirement applies when actual precursor data is claimed.
If valid actual emissions data are unavailable, the methodology allows use of applicable default values. Depending on circumstances, these defaults may lead to a less favourable emissions result than installation-specific substantiated data. The choice between actual values and defaults therefore affects reported outcomes.
The commercial implications should be assessed quantitatively rather than assumed from general low-carbon claims. Pellets with lower embedded emissions or more reliable documentation may reduce emissions attributed to downstream steel and improve an EU importer’s CBAM certificate position. Such potential benefits can offset part of a higher purchase price if calculated within the compliance framework.
Operational documentation and traceability for CBAM compliance files
CBAM controls should build on existing operational documentation where possible. Records mentioned include production orders, warehouse movements, fuel-meter data and material issues recorded in enterprise resource planning (ERP) systems, alongside applicable precursor and production records. A dedicated spreadsheet can support calculations but should not be the only record for emissions allocation.
The reported value must remain traceable to underlying purchasing and production documentation. This is particularly relevant when precursor-specific actual emissions values are applied. For integrated mills, the objective is to connect the emissions value to actual material entering production within the installation and reporting period covered by verification evidence.
Changes in suppliers, sourcing routes, prices or regulatory requirements should be reflected through controlled assumptions and documented procedures. The same approach is described as helping management distinguish investments that reduce current CBAM costs from measures that improve wider product footprint or reduce energy costs. Each benefit should be recorded against the relevant calculation boundary to avoid double counting.
Cross-border supply chains for pellets used by Southeast European mills
Steelmakers in South-East Europe often obtain raw materials through international commodity supply chains. As a result, CBAM data requirements can extend to pellet producers and other suppliers beyond where steel is manufactured. This affects compliance responsibilities across multiple tiers of procurement.
A Balkan steel mill cannot reconstruct credible installation-level precursor emissions data after material has been consumed if necessary supplier information was not collected earlier. Early contractual requirements are therefore described as important for maintaining a complete emissions record. Integrated steelmakers are also expected to incorporate CBAM data quality into raw-material qualification procedures and supplier scorecards.
Long-term pellet supply contracts should specify obligations to provide installation-level emissions information, verification reports and correction notices aligned with the steelmaker’s reporting calendar. These requirements apply to pellet suppliers, mining groups, traders, procurement teams and EU importers alike. The importer needs a defensible emissions figure for its CBAM declaration while suppliers must maintain records traceable to the relevant installation and reporting period.
Timing of contractual controls and internal alignment across functions
The compliance file should connect CN code, precursor information, production-process boundary, material records and verified emissions value. It should also identify who approves each assumption and establish a documented fallback where preferred treatment cannot be substantiated. A less favourable fallback may still be preferable if an evidence gap is discovered during interaction with an accredited verifier, customs authority or authorised CBAM declarant.
Resolving these issues before a transaction or reporting period is finalised can simplify subsequent price adjustments, verification changes and management reporting. Purchasing, production, customs and finance teams should work from consistent underlying records so companies can explain reported figures to both verifiers and commercial managers while identifying operational conditions that could change results.
Under CBAM, the emissions value associated with steel can be influenced before iron ore enters the furnace. For integrated steelmakers, upstream precursor data quality is therefore part of raw-material procurement, supplier management and downstream carbon-cost control within the compliance process described for pellet-based precursors.
