Iron & Steel
Connect material origin, composition, production routes, carbon footprint and recycled-content evidence across ironmaking, steelmaking, casting and downstream processing.
Circularise collects supplier evidence, links material and production records across transformations, and shares controlled product information for Digital Product Passport preparation, applicable trade requirements, carbon reporting and customer requests.
Iron and steel data model
Iron & Steel
Connected supplier and production evidence
Material and product identity
Distinguish iron inputs, cast iron products, steel products and manufactured components.
Production and origin
Explain where materials came from and how they were processed.
Carbon and circularity
Keep environmental values connected to their calculation basis.
Technical and compliance evidence
Connect declarations to the materials and products they describe.
Prepare for Digital Product Passports
Build the product and supplier data foundation ahead of the final ESPR requirements for iron and steel.
Prove origin and processing
Connect country of origin, melt-and-pour country, heat number and supporting certificates to the steel products placed on the market.
Reuse verified evidence
Use the same connected data across DPPs, CBAM workflows, construction documentation, procurement and customer disclosures.
WHAT CIRCULARISE COVERS
Iron producers, foundries, steelmakers and processors already hold substantial technical information. The challenge is connecting it across suppliers, production stages and customer systems.
Circularise connects that evidence to material and product records, making it easier to answer requests from automotive, construction, machinery and other downstream industries.
Connect pig iron, direct-reduced iron - including hot-briquetted iron - and scrap records to the batches that use them. For foundries, maintain links between feedstock, casting composition, production records and customer components.
Carry relevant evidence from steelmaking into slabs, billets, coils, sheets, bars, tubes and downstream parts. Preserve the relationship between source documents and the products created through casting, rolling, cutting or fabrication.
Organise production-route, emissions and origin information for applicable CBAM obligations and customer purchasing criteria. For imports covered by EU steel trade measures, connect melt-and-pour evidence and Mill Test Certificates to the relevant consignments.
Provide material information for automotive circularity work under ELV rules and construction-product documentation where applicable. Prepare evidence for the proposed low-carbon purchasing criteria and relevant origin conditions, keeping each requirement tied to its actual scope.
Implementation workflow
Iron and steel information passes through multiple suppliers and production stages. An ongoing data workflow keeps evidence connected as materials are transformed, so it can be reused across product passports, procurement and customer disclosures.
Request composition, origin, recycled-material and emissions information from suppliers. Bring together iron feedstock records, foundry certificates, steel Mill Test Certificates and supporting declarations, with clear ownership and review status.
Connect incoming materials to production batches and outputs, including iron reduction, melting, casting and steel processing. Record transformations, quantities and allocation methods so downstream claims remain connected to their evidence.
Create permissioned disclosures for customers and partners, and prepare product-passport views as requirements become final. Keep published information linked to its source, methodology and applicable product identifier.
Iron and steel data model
The exact fields depend on the product and applicable rules. Start by connecting material identity, production history, origin and sustainability evidence to clear data owners and supporting documents, ready to incorporate the final regulatory requirements.
Distinguish iron inputs, cast iron products, steel products and manufactured components.
Explain where materials came from and how they were processed.
Keep environmental values connected to their calculation basis.
Connect declarations to the materials and products they describe.
Iron and steel readiness
Build around today’s supply-chain needs while preparing for future product-specific requirements.
Separate iron inputs, castings, intermediate steel products and finished components. Identify where your business acts as manufacturer, importer, processor or supplier.
Start with information that depends on upstream partners: production location, composition, emissions, scrap inputs and supporting certificates.
Define how input batches connect to outputs, including blending, remelting, casting and cutting. Agree how quantities, losses and claims are recorded.
Identify data owners and integrations with existing production, ERP, quality and environmental systems. Decide which information can be shared and with whom.
Iron and steel are an ESPR priority, but the final delegated act will determine covered products, required information and application dates. The Commission currently indicates adoption in Q4 2026. In the meantime, companies can begin tracing material flows and linking supplier, production and sustainability evidence to their products.
Responsibilities depend on the legislation and the operator’s role. Under ESPR, manufacturers have core product-compliance duties, while importers and distributors have their own checks and obligations. Upstream suppliers may need to provide evidence even when they do not issue the finished product’s passport. Connecting the supply chain is therefore essential: each company needs access to reliable information from the actors that generate it, while retaining responsibility for its own obligations.
CBAM covers specified iron and steel goods according to customs classification and applicable exemptions. Relevant businesses need emissions information calculated under CBAM rules. Circularise connects supplier and production evidence to imported goods; a product carbon footprint, environmental declaration or DPP does not automatically satisfy CBAM.
Iron castings and steel components enter vehicles through multiple suppliers. Their composition and material evidence can help vehicle manufacturers address circularity, recyclability and end-of-life information requirements. ELV obligations must be assessed at the vehicle and relevant component level; they do not make every iron or steel supplier a vehicle-passport issuer.
Applicability follows the product placed on the market. A cast iron pipe or steel construction product may fall under construction product rules; steel packaging has packaging requirements. Supplying metal for a battery casing does not itself create a battery-passport obligation for the metal supplier.
