CBAM Compliance Checker &
Carbon Cost Estimator

CBAM — the Carbon Border Adjustment Mechanism (EU Regulation 2023/956) — is an EU carbon tariff on imports of carbon-intensive goods from non-EU countries. It prevents "carbon leakage": the risk that EU climate policy drives production to countries with laxer emission rules, only for those goods to be re-imported. By pricing embedded emissions at the border, CBAM levels the playing field between EU producers (who pay EU ETS costs) and importers.

CBAM covers cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. These sectors together represent the highest carbon-leakage risk and are the most energy- and emission-intensive industrial categories traded internationally.

The transitional phase (reporting only, no certificate purchases) ran from 1 October 2023 to 31 December 2025. From 1 January 2026, importers must purchase and surrender CBAM certificates equal to the embedded emissions of their imports, adjusted for any carbon price already paid in the country of origin.

CBAM certificate prices mirror the EU ETS (Emissions Trading System) carbon price. The European Commission publishes a weekly average auction price in EUR per tonne of CO₂. Importers buy certificates at this price via the CBAM Registry and surrender them annually by 31 May for the preceding calendar year.

Embedded (or "embodied") emissions are the greenhouse gases released during the production of a good, including both direct emissions (from the production process itself) and, for certain goods, indirect emissions (from electricity consumed during production). Importers must use actual production data where available, or fall back on default values published by the European Commission per sector and country.

Yes. If the exporting country levies a carbon price on the production of CBAM goods, importers can deduct an equivalent amount from their CBAM obligations. Detailed evidence of the carbon price paid (and that it was not rebated at export) must be provided to the EU CBAM authority.

The EU importer (or their customs representative) is legally responsible for CBAM compliance: reporting embedded emissions, purchasing certificates, and submitting the annual CBAM declaration. However, importers rely heavily on their non-EU suppliers for accurate production and emission data.

The EU importer pays — not the non-EU exporter. The authorised CBAM declarant (the EU-based company or its customs representative) must purchase and surrender CBAM certificates. Non-EU exporters have no direct payment obligation to the EU, but are indirectly affected: EU buyers will negotiate lower purchase prices or switch to lower-carbon suppliers to reduce their own certificate costs.

CBAM is neither a traditional tax nor a customs tariff. It is a carbon cost equalisation mechanism: EU importers must purchase "CBAM certificates" equal to the embedded emissions of their imports, at a price matching the EU ETS carbon price. The EU designed this approach to be WTO-compatible — it applies the same carbon cost to imported goods as EU producers pay under the ETS. Trading partners sometimes call it a "carbon border tax," but legally it is a certificate-based carbon pricing instrument.

The CBAM certificate price — the key cost factor for 2026 — is not fixed. It is recalculated weekly by the European Commission as the preceding week's average EU ETS auction price. In early 2026, EU ETS prices trade at approximately €55–€75 per tonne of CO₂. At €65/tCO₂, the CBAM cost per tonne of BF-BOF steel is ~€122.85; primary aluminium ~€747.50; grey hydrogen ~€650. The Commission publishes the current weekly price on the official CBAM Registry portal.

The CBAM default markup — also called the 10% default penalty — applies when importers cannot provide verified actual emission data and must fall back on EU Commission default emission factors. The effective emission factor is increased by 10%: effective factor = default × 1.10. For BF-BOF steel at €65/tCO₂, the markup costs an extra €12.29 per tonne. For primary aluminium it is €74.75 per tonne. Commissioning an EU-accredited third-party verifier to certify actual data from the supplier eliminates this surcharge entirely.

The penalty for failing to surrender sufficient CBAM certificates is €100 per tonne of CO₂ equivalent not covered, plus a requirement to surrender the missing certificates in the following year. The penalty is proportional to the emissions shortfall and is levied by national competent authorities. This is in addition to any customs or import duty penalties for non-registration.

Yes. Iron and steel is one of the six CBAM sectors. CBAM covers a wide range of steel products under CN codes 7201–7326, including pig iron, direct reduced iron (DRI), hot-rolled and cold-rolled flat products, sections, bars, wire rod, tubes, and pipes. Both direct emissions (from the furnace) and indirect emissions (from electricity in EAF production) are reportable depending on the production route.

Yes. India is not an EEA country and has no bilateral carbon pricing agreement with the EU qualifying for CBAM deduction. Steel and aluminium from Indian producers are among the most commonly imported CBAM-covered goods into the EU. Indian exporters will need to provide production and emission data to EU buyers to support their CBAM declarations.

Yes. China is subject to CBAM. China does have a national ETS (CN-ETS), but as of 2026 the EU Commission has not recognised it as qualifying for a full CBAM deduction — carbon price levels and verification standards do not yet meet EU requirements. EU importers of Chinese CBAM-covered goods must pay the full certificate cost.

Yes. The United States has no federal carbon price recognised by the EU for CBAM deduction. US exporters of CBAM-covered goods — steel, aluminium, fertilisers, cement, hydrogen, electricity — to the EU face the full CBAM certificate cost borne by the EU importer. Individual state-level carbon pricing schemes are unlikely to qualify for deduction without EU Commission formal recognition.

Y128 is the customs authorisation code EU importers must include in their customs declaration when importing CBAM-covered goods. It confirms the importer is a registered authorised CBAM declarant. The code is mandatory for any shipment above the de minimis threshold (net mass above 50 kg per consignment). Omitting Y128 can cause customs clearance delays or penalties from the national competent authority.

The first surrender of CBAM certificates is due by 31 May 2027, covering calendar year 2026 — the first full year of CBAM obligations. Importers must purchase certificates throughout 2026 and surrender them by the May 2027 deadline. Annual CBAM declarations must be filed by 31 May each year for the preceding calendar year.

CBAM does apply to secondary (recycled) aluminium, but the default emission factor is far lower: 0.14 tCO₂/t versus 11.50 tCO₂/t for primary aluminium. At €65/tCO₂, the CBAM cost for recycled aluminium is approximately €9.10/t compared to €747.50/t for primary. Importers must document with verified data that the material is genuinely secondary/recycled to use this lower factor.

Direct emissions are greenhouse gases released at the production site during manufacturing — for example, CO₂ from a blast furnace or a cement kiln. Indirect emissions are those from the electricity consumed during production. Under CBAM: cement, fertilisers, hydrogen, and electricity sectors report only direct emissions. Iron & steel and aluminium must include both direct and indirect emissions.

CBAM has a de minimis exemption: individual consignments with a net mass of 50 kg or less per shipment are exempt from CBAM declaration requirements. Separately, when cumulative import mass in a session exceeds 50 tonnes, the Y128 authorisation code becomes mandatory in the customs declaration. From 1 January 2026, all importers of CBAM goods above the per-consignment de minimis must comply with full certificate obligations.

Importing CBAM-covered goods without being registered as an authorised CBAM declarant is a violation of EU Regulation 2023/956. Consequences include: (1) national authorities may prohibit further imports until registration is complete; (2) financial penalties for non-registration and any unreported embedded emissions; (3) back-payment of CBAM certificates for all covered imports made while unregistered; (4) reputational and legal consequences with customs authorities. Registration must be in place before importing CBAM-covered goods from 1 January 2026.

Yes. The national competent authority may revoke authorised CBAM declarant status if: the declarant fails to submit annual CBAM declarations by 31 May; fails to surrender sufficient certificates; provides materially false or fraudulent emission data; or no longer meets registration criteria. Deregistration prevents further imports of CBAM-covered goods until re-registration is approved.

Certificates needed = (Quantity × Emission factor) − Carbon price deduction. Example: importing 1,000 t of BF-BOF steel (1.89 tCO₂/t) = 1,890 tCO₂e gross. If the exporting country charged an equivalent of 0.30 tCO₂/t, deduction = 300 tCO₂e, so you need 1,590 certificates. Each certificate represents one tonne of CO₂ equivalent and is purchased at the current weekly ETS price via the EU CBAM Registry.

Yes. CBAM certificates can be purchased in advance via the EU CBAM Registry at any point during the year. However, at the annual surrender deadline (31 May), any unused certificates can be partially repurchased by the national authority — up to one-third of total certificates held. Over-purchasing beyond that 33% buffer results in a financial loss. Importers should align purchases to expected import volumes.

From 2026, EU importers need: (1) Authorised CBAM declarant registration obtained via the EU CBAM Registry; (2) Single Administrative Document (SAD) with CN code (Box 33), country of origin (Box 34), and net mass (Box 35); (3) Embedded emission data — EU Commission defaults or a verified actual emission report; (4) Installation ID — mandatory when using actual rather than default values; (5) Carbon price documentation — if claiming a deduction for carbon costs paid in the country of origin; (6) Verifier accreditation certificate — if using actual emission data.

(1) Obtain an EORI number from your national customs authority; (2) Access the EU CBAM Registry via the European Commission's DG TAXUD portal using EU Login credentials; (3) Complete the declarant registration form with company details, EORI number, and import activity information; (4) Submit to your national competent authority for approval; (5) Receive your authorised declarant status and Registry access; (6) Begin purchasing CBAM certificates before importing. Registration should be completed before making any CBAM-covered imports in 2026.

Yes — an EORI number (Economic Operators Registration and Identification) is mandatory for CBAM. It is a unique identifier issued by EU customs authorities to all operators engaged in customs activities in the EU. Without an EORI number, an importer cannot register as an authorised CBAM declarant or submit customs declarations. EORI numbers are issued by the customs authority of the EU member state where the company is established, typically within a few days of application.

Yes. EU importers can appoint a customs representative (customs broker, freight forwarder, or trade compliance consultant) to act as their authorised CBAM declarant. The representative can register in the CBAM Registry, submit declarations, purchase certificates, and manage annual surrender obligations. However, the EU importer retains ultimate legal responsibility for the accuracy of declared embedded emissions. The customs representative must be established in the EU and hold appropriate customs representation authorisation.

During the CBAM transitional phase (October 2023 – December 2025), EU importers submitted a quarterly CBAM report within one month of each quarter's end. Each report declared: the quantity of CBAM goods imported, country of origin, embedded direct and indirect greenhouse gas emissions per product, and any carbon price paid in the country of origin. Reports were submitted via the EU CBAM Transitional Registry. From 1 January 2026, quarterly reports are replaced by the annual CBAM declaration and certificate surrender obligation.

CBAM declarations are submitted electronically via the EU CBAM Registry using a structured XML format defined by DG TAXUD. The XML schema covers: declarant identification, import transaction details, embedded emission data per CN code and installation, certificate purchase records, and deduction documentation. The Commission provides technical documentation and a test environment for the XML schema. Importers using ERP or trade compliance software (SAP, Oracle, Descartes) should verify their system supports the CBAM XML schema for automated declaration submission.

(1) Request the supplier to engage an EU-accredited verifier (accredited under ISO 14065 / EN ISO 14064-3) to audit their production processes and embedded emissions; (2) The verifier conducts an on-site or remote assessment; (3) The verifier issues a Verification Report stating verified specific embedded GHG emissions (tCO₂e/t); (4) The EU importer uses this verified figure in their CBAM declaration instead of the EU Commission default value. The Installation ID of the production facility must also be included in the declaration.

Yes. Russia is subject to EU CBAM for exports of steel, fertilisers, aluminium, and cement to the EU. Russia has a domestic carbon pricing instrument but its coverage and price level are substantially lower than the EU ETS, so only a partial deduction may be available. In practice, following sanctions imposed after 2022, Russian exports to the EU have significantly decreased across all CBAM sectors.

Yes, technically — though Ukraine has a specific context. Ukraine is a major steel exporter to the EU and is on an EU accession pathway, aligning with EU environmental standards. Trade agreements including the DCFTA provide preferential treatment but do not automatically exempt Ukraine from CBAM. As Ukraine's carbon market develops in alignment with the EU ETS framework, partial or full exemptions may become available in future.

Yes. Egypt is a significant exporter of fertilisers (ammonia, urea) and steel to the EU and is subject to CBAM from 1 January 2026. Egypt does not have a carbon pricing mechanism that qualifies for CBAM deductions. Egyptian exporters face the full CBAM certificate cost. Egypt has raised concerns about CBAM's impact on developing economies in international trade forums.

Yes. Brazil exports steel and aluminium to the EU and is subject to CBAM. Brazil has a developing domestic carbon market but it does not currently meet the criteria for a CBAM deduction. Brazilian steel and aluminium producers exporting to the EU face CBAM certificate costs from 2026.

Yes. South Korea exports steel, aluminium, and machinery parts to the EU and is subject to CBAM. South Korea operates its own ETS (K-ETS, launched 2015), and Korean exporters may be eligible for a partial CBAM deduction if they can demonstrate that a comparable carbon price was paid under the K-ETS. The extent of the deduction depends on documentation and the K-ETS price relative to the EU ETS price.

Yes. Japan exports steel, aluminium, and machinery to the EU and is subject to CBAM for CBAM-covered goods. Japan operates sector-level carbon pricing schemes, but these are not broadly equivalent to the EU ETS. Japanese exporters may claim partial deductions for carbon costs paid under Japan's schemes. Full CBAM certificate obligations apply from 1 January 2026.

Switzerland has a bilateral carbon pricing link with the EU: the Swiss ETS is linked to the EU ETS, meaning Swiss producers in covered sectors already pay a carbon price equivalent to the EU ETS. This linkage means Swiss exporters of CBAM-covered goods are generally eligible for a full deduction or effective exemption from CBAM certificate costs, provided they can document the carbon price paid. Switzerland is not formally exempt like EEA countries, but the ETS linkage makes the practical CBAM cost near zero.

Yes. Taiwan exports significant volumes of steel and aluminium to the EU and is subject to CBAM from 1 January 2026. Taiwan has introduced a carbon pricing framework but it is at an early stage. Taiwanese exporters are unlikely to qualify for significant CBAM deductions initially, meaning they face most or all of the full certificate cost.

Generally, no. Steel scrap (CN 7204) and aluminium scrap (CN 7602) are not directly listed as CBAM-covered products in Annex I of Regulation 2023/956. However, if scrap is processed into a CBAM-covered finished product and that product is then imported into the EU, the finished product is subject to CBAM. EAF steel (scrap-based) carries a significantly lower default emission factor (0.429 tCO₂/t) than BF-BOF steel (1.89 tCO₂/t).

Yes. Stainless steel products fall under CN codes 7219–7220 (flat-rolled products of stainless steel) and related downstream codes, which are included in CBAM scope for iron and steel under Annex I of Regulation 2023/956. The applicable emission factor depends on the production route used. Stainless steel's higher alloy content (chromium, nickel) may also affect the specific embedded emission calculation.

No. Solar panels (photovoltaic modules) are not currently covered by CBAM — they fall under CN codes in chapters 85 and 90, which are not in CBAM Annex I. However, the aluminium frames and steel mounting structures used in solar installations are CBAM-covered materials when imported separately. There is ongoing discussion about extending CBAM to additional products, but no regulation extending it to solar panels has been adopted as of 2026.

No. Plastics, polymers, and most chemicals are not currently covered by CBAM. The only chemical products in CBAM scope are specific fertiliser products (ammonia, nitric acid, urea, ammonium nitrate, and NPK compounds) and hydrogen. The European Commission has identified organic chemicals and polymers as potential candidates for future CBAM expansion, but no regulation extending CBAM to plastics has been adopted as of 2026.

No. Copper and copper products are not currently covered by CBAM. The six regulated sectors are cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen. Copper is identified as a potential future sector for CBAM expansion — the Commission is expected to review scope expansion around 2025–2026, with possible inclusion of additional metals from 2030.

Yes. Ammonia (CN 2814) is explicitly listed in CBAM Annex I under the fertilisers sector. It carries a default emission factor of 1.894 tCO₂e/t due to the energy-intensive Haber-Bosch synthesis process. At €65/tCO₂, that is approximately €123 per tonne in CBAM certificate cost. Importers of ammonia must declare embedded emissions and purchase certificates from 1 January 2026.

The CBAM regulation does not explicitly exclude used or second-hand goods. In principle, CBAM applies based on the CN code of the imported product regardless of condition. In practice, second-hand goods rarely trigger CBAM obligations because: (1) they may be classified under different CN codes; (2) attributing embedded emissions of used goods is complex; and (3) the regulation focuses on industrial imports. Importers of used industrial equipment containing CBAM-covered materials should seek specific customs and legal advice.

No. CBAM certificates cannot be traded between importers on a secondary market. Each certificate is issued in a specific importer's CBAM Registry account and can only be used by that importer to meet their own surrender obligation. Unused certificates at year-end can be sold back to the national authority (up to one-third of total held). CBAM is a compliance mechanism, not a trading scheme — the price is set weekly by the Commission, not through certificate trading.

Yes. Under the EU's Own Resources Decision, CBAM revenues flow into the EU budget and are earmarked partly to fund REPowerEU (energy independence and clean energy investment) and the Global Gateway initiative, which includes climate finance for developing countries. The EU has committed that a portion of CBAM revenues will support climate action in third countries affected by CBAM. The Commission projects CBAM revenues of €1–3 billion per year at full implementation.

No. EU domestic manufacturers are not subject to CBAM — it applies only to imports. EU manufacturers already pay for their emissions through the EU ETS. CBAM benefits EU manufacturers by levelling the playing field: before CBAM, imported goods from countries without carbon pricing had a cost advantage. CBAM eliminates that advantage by applying the same carbon price at the EU border, making EU-produced steel, cement, and aluminium more competitive against non-ETS imports.

At €65/tCO₂ and the default emission factor of 0.763 tCO₂/t for Portland cement, CBAM adds approximately €49.60 per tonne to the cost of importing cement from non-ETS countries. For clinker (0.831 tCO₂/t), the surcharge is ~€54/t. This is significant in a sector where EU–non-EU price differences are often €30–60/t, and is expected to reduce the price advantage of imported cement from Turkey, Egypt, and Asia.

CBAM adds approximately €156 per tonne to imports of mixed/compound fertilisers at the default factor of 2.4 tCO₂/t at €65/tCO₂. For urea (1.694 tCO₂/t) the surcharge is ~€110/t; for ammonia (1.894 tCO₂/t) ~€123/t. These are significant cost increases given the intense global price competition from Russian, Egyptian, and Chinese fertiliser producers. N₂O abatement technology at the production plant can substantially reduce the actual emission factor and the CBAM cost.

The construction industry is indirectly affected through higher costs for imported steel, cement, and aluminium. For projects using imported BF-BOF steel with a ~€122.85/t CBAM surcharge, a building using 500 tonnes of steel faces an additional ~€61,000 in materials costs. Cement-intensive infrastructure projects face ~€50/t. The construction sector should assess CBAM exposure, consider domestic sourcing, and factor CBAM costs into project budgets and tender pricing from 2026 onwards.

The automotive industry is indirectly affected through higher costs for imported steel and aluminium used in vehicle manufacturing. Finished vehicles are not CBAM-covered, but suppliers importing steel coil, aluminium sheet, or structural components face CBAM costs passed through the supply chain. An electric vehicle battery enclosure using 50 kg of primary aluminium from a coal-grid smelter could carry ~€37.50 in CBAM-related material cost per vehicle. Automotive manufacturers should audit their tier-1 and tier-2 supply chains for CBAM exposure.

CBAM is broadly positive for EU steel producers. Before CBAM, EU steelmakers paid for emissions under the EU ETS while competing against steel from countries without comparable carbon pricing. CBAM closes this gap: at €65/tCO₂, BF-BOF steel imports carry a ~€122.85/t surcharge, improving the competitive position of EU producers. EU EAF producers (lower emissions) benefit most. The EU steel industry lobbied strongly for CBAM and considers it essential to prevent carbon leakage under the EU's 2050 net-zero target.
