General Summary
EU CBAM entered its definitive phase on January 1, 2026, making the Carbon Border Adjustment Mechanism a live financial obligation for every EU importer of goods in 6 sectors: iron and steel, cement, aluminium, fertilizers, electricity, and hydrogen. The mechanism requires authorized EU importers to surrender CBAM certificates corresponding to the embedded CO₂ emissions of their imports, priced at the EU ETS carbon price (approximately €70/tCO₂ as of late March 2026, though this figure fluctuates daily with ETS auction results).
CBAM is established by Regulation (EU) 2023/956 and substantially amended by Regulation (EU) 2025/2083 (the "Omnibus simplification"). It is not a carbon tax, not a tariff, and not a border duty. CBAM is a certificate-based mechanism that equalizes the carbon cost between goods produced inside the EU under the EU Emissions Trading System and equivalent goods imported from countries without comparable carbon pricing. The goal is to prevent carbon leakage: the displacement of production, and its associated CO₂ emissions, to jurisdictions where emissions are unpriced.
This guide covers every dimension of the EU CBAM mechanism: the legal architecture built on 13 implementing regulations, how embedded emissions are calculated and verified, how the certificate obligation works, the free allocation phase-out schedule through 2034, the six sectors in scope, financial penalties, the Article 9 carbon price deduction, open questions under active regulatory development, and what the mechanism means for EU importers and their non-EU supply chain partners.

What Is the EU CBAM and Why Does It Exist
EU CBAM exists because the EU Emissions Trading System prices carbon emissions from domestic EU producers but not from competing importers, creating an incentive to shift production offshore where carbon is unpriced. The Carbon Border Adjustment Mechanism closes this gap by requiring EU importers of carbon-intensive goods to surrender CBAM certificates proportional to the embedded greenhouse gas emissions of their imports.
The mechanism's legal basis is Article 192(1) TFEU, confirming CBAM is an environmental policy measure, not a trade measure. This classification shapes everything: CBAM does not set custom duties, does not change tariff bindings under WTO schedules, and does not impose a tax in the fiscal sense. It creates a certificate obligation linked directly to the EU ETS carbon price.
The Carbon Leakage Problem CBAM Solves
Carbon leakage occurs when EU industries, facing carbon costs under the ETS, lose market share to competitors in countries where production generates equivalent CO₂ but no equivalent price is paid. The result is that EU emissions decline on paper while global emissions stay constant or increase, because production simply relocates. The OECD estimates that CBAM captures less than 0.5% of global emissions in its first phase (2026), but the mechanism's purpose is structural: it removes the financial incentive for carbon leakage from the EU market, the world's largest single import market for industrial goods.
Before CBAM, EU producers received EU ETS free allocation as a temporary compensation for this leakage risk. Free allocation is now being phased out in parallel with CBAM's phase-in between 2026 and 2034, with the CBAM factor rising from 2.5% in 2026 to 100% in 2034. At the 2026 level (97.5% of free allocation still intact), net CBAM costs are deliberately small. An EU importer of blast-furnace steel paying an EU ETS price of €70/tCO₂ faces a gross CBAM cost of approximately €140 per tonne but a net cost of only €3.50/tonne after applying the 2.5% CBAM factor. That same net cost reaches approximately €67.90/tonne by 2030 as the CBAM factor jumps to 48.5%.
The Six Sectors Covered by EU CBAM
Regulation (EU) 2023/956 Annex I lists the 6 sectors subject to CBAM, each identified by specific CN (Combined Nomenclature) codes. The sectors covered by EU CBAM carbon border adjustment requirements are listed below:
- Iron and steel: CN codes from Chapters 72 and 73, including pig iron, hot-rolled flat products, bars, wire, tubes, pipes, and structural profiles. Direct emissions only; indirect emissions not priced. The blast-furnace route (BF-BOF) carries approximately 2.0 tCO₂/tonne; the electric arc furnace scrap route (EAF) carries approximately 0.5 tCO₂/tonne.
- Cement: CN codes 2523 10, 2523 21, 2523 29, and 2523 30 (clinker and Portland cement). Both direct and indirect emissions are priced. The typical embedded emissions factor for Portland cement is approximately 0.83 tCO₂/tonne.
- Aluminium: CN codes from Chapter 76, covering primary and secondary aluminium and downstream profiles. Direct emissions plus perfluorocarbons (CF₄ with GWP 6,630 and C₂F₆ with GWP 11,100) are priced; indirect emissions from electricity consumption are not priced under the certificate obligation (though included in published default values). Primary aluminium embedded emissions average approximately 1.5 tCO₂/tonne (direct only).
- Fertilizers: CN codes from Chapter 28 (ammonia, CN 2814) and Chapter 31 (urea, ammonium nitrate, mixed fertilizers). Both direct and indirect emissions are priced. Urea carries approximately 2.5 tCO₂e/tonne. Nitrogen oxide (N₂O) from the production process is covered.
- Electricity: CN code 2716 00 00. No de minimis threshold applies. Priced on embedded CO₂ per MWh at the point of generation, traded through physical interconnectors only.
- Hydrogen: CN code 2804 10 00. No de minimis threshold applies. Grey hydrogen produced by steam methane reforming carries approximately 9–12 tCO₂/tonne H₂; green hydrogen from renewable electrolysis carries approximately 0–0.3 tCO₂/tonne H₂.
The geographic scope covers imports into the EU customs territory from all third countries. Annex III countries, specifically Iceland, Liechtenstein, Norway, and Switzerland, are exempt because their electricity markets integrate with the EU market and they operate the EU ETS or an equivalent qualifying carbon pricing scheme.
How EU CBAM Embedded Emissions Are Calculated
CBAM embedded emissions are the greenhouse gas emissions from the production process at the production installation that produced the imported goods, expressed in tonnes of CO₂e per tonne of goods (specific embedded emissions). For complex goods, goods produced using one or more Annex I precursors, the embedded emissions of each precursor carry through into the finished good's total. Steel pipes are complex goods; their embedded emissions include both the direct emissions from the pipe mill and the embedded emissions of the steel from which the pipes were formed.
The two primary calculation methods available under IR (EU) 2025/2547 are the standard monitoring plan method (Equation 11, based on measured fuel consumption and process emissions) and the mass balance method (Equation 12, for installations where carbon content of inputs and outputs can be directly measured). Cement uses specialized equations: Equation 64 for clinker ratio calculations and Equation 65 for nitrogen content in fertilizers.
Understanding how embedded emissions are calculated is central to the CBAM embedded emissions obligation, because the number of certificates an EU importer must surrender equals the total embedded emissions in all CBAM goods imported during the calendar year, adjusted for any carbon price paid in the country of origin under Article 9.
Direct vs. Indirect Embedded Emissions
Direct embedded emissions come from the production process itself, including fuel combustion, chemical processes (notably limestone calcination in cement production, which alone accounts for approximately 60% of cement's total CO₂), and heat generation within the installation. Direct embedded emissions are priced under EU CBAM for all 6 sectors.
Indirect embedded emissions come from the electricity consumed during production. Indirect emissions are priced under CBAM for cement and fertilizers only. For steel and aluminium, the electricity consumed in production generates significant CO₂ at the grid level (aluminium smelters consume approximately 14–16 MWh per tonne of primary metal) but this electricity-related carbon cost is not included in the CBAM certificate obligation. The choice to exclude indirect emissions from steel and aluminium reflects a judgment that these sectors' electricity consumption patterns make verification too complex, while cement and fertilizers have sufficiently concentrated and measurable electricity intensity to justify inclusion.
Default Values: When Verified Data Is Unavailable
Default values are published emission intensity values an EU importer uses when the non-EU production installation cannot or does not provide verified actual emissions data. Default values are established by IR (EU) 2025/2621 for the definitive phase and carry a mark-up above country-specific averages: 10% in 2026, 20% in 2027, and 30% from 2028 onward for steel, cement, aluminium, and hydrogen. Fertilizers receive a more modest 1% mark-up, reflecting agricultural price sensitivity and food security concerns cited explicitly in the Omnibus explanatory memorandum.
The mark-up structure creates a growing financial incentive to measure and verify actual emissions rather than rely on defaults. In 2026, this incentive is counterintuitively weak: due to the interaction between the SEFA (Specific Embedded Free Allocation) methodology in IR 2025/2620 and the first-year defaults, specific product-country combinations carry lower CBAM liability under default values than under verified actual values. This reverses from 2027 as both the mark-up increases to 20% and the free allocation phase-out accelerates. Industry associations have flagged this 2026 paradox to DG TAXUD; no official clarification has been issued as of April 2026.
Third-Party Verification Requirements
Embedded emissions data must be verified by an accredited third-party verifier under DR (EU) 2025/2551. Verifiers must be accredited by a national accreditation body recognized by European Accreditation (EA) under EN ISO/IEC 14065. A mandatory physical site visit to the non-EU production installation is required for the first verification period (covering calendar year 2026 data). Verifiers cannot be affiliated with the installation being verified.
The European Accreditation Task Force on CBAM was established in March 2026. Verifiers cannot register in the CBAM Registry until September 1, 2026 under Regulation (EU) 2025/2083. This creates a tight operational window: verifiers register from September 2026, conduct site visits and issue verification reports for calendar year 2026, and importers must include verified data in the first CBAM declaration due September 30, 2027. Verifier fees range from €5,000 to €50,000 per installation depending on complexity, meaning large importers sourcing from 50 non-EU installations face first-cycle verification costs between €250,000 and €2.5 million.
How CBAM Certificates Work
CBAM certificates are electronic certificates, each corresponding to one tonne of CO₂e of embedded emissions in imported CBAM goods. The financial obligation of EU CBAM runs entirely through the certificate system: purchase, hold, surrender, and where applicable, buy back or allow cancellation.
EU importers obtain certificates exclusively through the CBAM Registry, operated by DG TAXUD (Directorate-General for Taxation and Customs Union) using the same UUM&DS authentication infrastructure as the EU ETS. Certificate sales begin February 1, 2027. The price of each certificate is calculated from EU ETS auction prices: for calendar year 2026, the price is the quarterly average of EU ETS auction clearing prices (per IR 2025/2548); from 2027 onward, it switches to the weekly average of EU ETS auction closing prices. At the late March 2026 EU ETS price of approximately €70/tCO₂, a certificate covering one tonne of CO₂ costs approximately €70. This figure fluctuates with each EU ETS auction.
The certificate obligation covering the 2026 calendar year (the first year of the definitive phase) must be fulfilled in three stages:
- Quarterly holding: At the end of each calendar quarter, authorized declarants must hold CBAM certificates equal to at least 50% of cumulative embedded emissions of all CBAM goods imported since January 1 of that year. This quarterly holding requirement (Article 22(2) as amended by Regulation (EU) 2025/2083) prevents importers from deferring all purchasing to the annual deadline. The original regulation set this threshold at 80%; the Omnibus reduced it to 50%.
- Annual declaration and surrender: By September 30, 2027 (the first declaration deadline under Article 6 as amended), authorized declarants submit the CBAM declaration covering all 2026 imports and surrender certificates equal to total embedded emissions minus any Article 9 deduction for carbon prices paid in countries of origin.
- Buyback: Authorized declarants may sell back to the competent authority up to 50% of certificates purchased in the 2026 calendar year, at the price paid, by October 31, 2027. Unused certificates not bought back are cancelled on November 1, 2027.
The complete certificate obligation lifecycle, including how to purchase, track holdings, and surrender through the CBAM Registry, is covered in detail in the CBAM certificates guide.

The Article 9 Carbon Price Deduction
Article 9 of Regulation (EU) 2023/956 allows authorized declarants to reduce their certificate surrender obligation by the carbon price effectively paid in the country of origin for the embedded emissions of the imported goods. The deduction equals the verifiable carbon price actually paid, converted to EUR, applied to the emissions covered by that price.
The deduction applies only to carbon prices that are legally binding and effectively enforced in the third country. Voluntary carbon offsets do not qualify. Internal corporate carbon pricing does not qualify. Free allocation received by a non-EU producer under a foreign ETS reduces the qualifying amount. Only the portion of emissions for which a price was actually paid counts.
Four countries currently operate qualifying or potentially qualifying carbon pricing schemes that matter for major CBAM export volumes: South Korea (K-ETS, covering steel), Switzerland (ETS linked to EU ETS), and China (national ETS, but its intensity-based structure complicates conversion to the EU's absolute-emissions basis). Turkey enacted Climate Law No. 7552 in July 2025 establishing a legal basis for a Turkish ETS, but the pilot phase runs with full free allocation, meaning no effectively paid carbon price exists yet for Turkish exporters.
Financial Penalties for Non-Compliance
The penalty structure under Article 26 as amended by Regulation (EU) 2025/2083 contains 2 distinct tiers. The penalties applicable under the EU CBAM definitive phase are listed below:
- Authorized declarant fails to surrender sufficient certificates: €100 per tonne CO₂e not covered (inflation-adjusted from the base year). This applies to authorized declarants who submit their declaration and surrender fewer certificates than their declared embedded emissions require.
- Importing CBAM goods without authorization: €300 to €500 per tonne CO₂e (3 to 5 times the standard rate), applied to unauthorized persons importing Annex I goods. This penalty band reflects the severity of operating entirely outside the authorization system.
The €100/tCO₂e penalty is exact and harmonized across all 27 member states under the Omnibus amendment. The original regulation left member states discretion, leading to divergent penalty structures.
The EU CBAM Authorization and Registration Process
Every EU importer of Annex I goods during the definitive phase must hold authorized CBAM declarant status (Article 3(15), Article 4). Authorization is granted by the competent authority of the member state where the importer is established. The competent authority has 120 days maximum to issue a decision on a complete application, per Article 4(1) of IR 2025/486.
The authorization application requires a minimum of 5 years of customs and tax compliance history (Article 5(5) of the regulation and IR 2025/486). The application is submitted through the Authorization Management Module (AMM) of the CBAM Registry, which became operational on March 31, 2025. By January 7, 2026 (one week into the definitive phase), over 12,000 authorization applications had been submitted and over 4,100 operators had been authorized.
Importers who submitted a provisional authorization application by March 31, 2026 may continue importing CBAM goods pending the competent authority's decision. The 20 EU member states that designated environment or energy departments as competent authorities and the 7 that designated financial or tax departments have their own national application portals, all feeding into the common CBAM Registry infrastructure.
The CBAM Registry Infrastructure
The CBAM Registry is operated by DG TAXUD and governed by IR 2024/3210 as amended by IR 2025/2550. Authentication uses UUM&DS (User Management and Digital Signature), the same system as the EU ETS Registry. The registry manages four functions: authorized declarant accounts, CBAM certificate holdings, declaration filing, and customs data integration.
IR 2025/2619 establishes the real-time data exchange between EU customs authorities and the CBAM Registry. When an import declaration is filed at EU customs for Annex I goods, the customs system automatically validates whether the declarant holds a current authorization. This real-time check, operational from January 1, 2026, means unauthorized importers are identified at the customs entry point rather than after the fact.
The Common Central Platform for certificate sales (the marketplace where authorized declarants purchase CBAM certificates at the ETS-linked price) was put to tender on February 16, 2026, with responses due April 6, 2026. The platform must be operational before February 1, 2027, when certificate sales are required to begin.
The Free Allocation Phase-Out Schedule: 2026 to 2034
The EU CBAM financial significance grows each year in direct proportion to the phase-out of EU ETS free allocation for CBAM sectors. Free allocation, the provision of ETS allowances to domestic EU producers at no charge, has historically protected EU industries from carbon leakage competition. CBAM replaces this protection mechanism for the import side, while free allocation is simultaneously withdrawn on the domestic side.
The phase-out schedule, established in Article 10a(1a) of EU ETS Directive 2003/87/EC as amended, determines the CBAM factor: the fraction of embedded emissions for which certificates must be surrendered each year. The 10-year schedule from 2026 to 2034 is shown in the table below.
| Year | CBAM Factor | Free Allocation Remaining | Net CBAM Cost (BF-BOF Steel at €70/tCO₂) |
|---|---|---|---|
| 2026 | 2.5% | 97.5% | €3.50/t |
| 2027 | 5% | 95% | €7.00/t |
| 2028 | 10% | 90% | €14.00/t |
| 2029 | 22.5% | 77.5% | €31.50/t |
| 2030 | 48.5% | 51.5% | €67.90/t |
| 2031 | 61% | 39% | €85.40/t |
| 2032 | 73.5% | 26.5% | €102.90/t |
| 2033 | 86% | 14% | €120.40/t |
| 2034 | 100% | 0% | €140.00/t |
Net costs assume €70/tCO₂ EU ETS price and 2.0 tCO₂/t BF-BOF emission factor. Actual costs fluctuate with ETS price.
The steepest jump in the schedule occurs between 2029 and 2030, when the CBAM factor increases from 22.5% to 48.5%. This 26 percentage point increase in a single year represents the most critical planning window for EU importers and their non-EU supply chain partners. Importers sourcing high-emission goods who have not acted on supply chain decarbonization by 2028 face a near-doubling of their net CBAM cost in a single year when the 2029-to-2030 cliff arrives.
The Legal Architecture: 13 Implementing Regulations and the Omnibus Amendment
EU CBAM operates through a primary regulation and 13 implementing and delegated regulations that govern every procedural detail. The legal architecture of the carbon border adjustment mechanism consists of primary legislation and secondary legislation.
Primary legislation:
- Regulation (EU) 2023/956 of 10 May 2023 (OJ L 130, 16.5.2023, pp. 52–104): The founding regulation. 41 Articles, 7 Annexes. Legal basis: Article 192(1) TFEU. Establishes scope, obligations, penalties, registry, and the link to ETS.
- Regulation (EU) 2025/2083 of 8 October 2025 (OJ L, 2025/2083, 17.10.2025): The Omnibus simplification. Amends the primary regulation with the following key changes: 50-tonne annual de minimis threshold, September 30 annual declaration deadline, February 1, 2027 certificate sales start, 50% quarterly holding requirement, €100/tCO₂e harmonized penalty, and verifier registration opening from September 1, 2026.
The 13 implementing and delegated regulations covering procedural requirements, from IR 2023/1773 (transitional period, historical) through IR 2025/2621 (definitive phase default values) and DR 2025/2551 (verifier accreditation), establish the complete compliance framework that authorized declarants and their suppliers must navigate.
The De Minimis Threshold
The de minimis threshold, inserted by Article 2(3a) of Regulation (EU) 2025/2083, exempts importers whose total annual CBAM goods imports do not exceed 50 tonnes of net mass per calendar year from all CBAM obligations. This threshold applies across all Annex I goods combined except electricity and hydrogen, which have no de minimis threshold.
The 50-tonne threshold is applied per importer, per calendar year. An EU company importing 25 tonnes of steel and 20 tonnes of cement in a single year (45 tonnes combined) falls below the threshold. The same company importing 60 tonnes of steel in a year is above the threshold and has full CBAM obligations for all its Annex I imports. The original regulation used a €150 per consignment threshold based on customs value; the Omnibus replaced this with the 50-tonne annual mass threshold as a simplification.
EU CBAM and the Carbon Border Adjustment in Practice: Sector Cost Examples
The practical financial impact of the EU CBAM carbon border adjustment obligation varies substantially by sector and production route. The cost table below shows gross CBAM costs at the late March 2026 EU ETS reference price of approximately €70/tCO₂ (this price fluctuates daily and may be significantly different by the time any declaration is filed).
| Product and Route | Emission Factor (tCO₂e/t) | Gross CBAM Cost at €70/tCO₂ | Net 2026 Cost (2.5% factor) | Net 2030 Cost (48.5% factor) |
|---|---|---|---|---|
| Steel, blast furnace (BF-BOF) | ~2.0 | ~€140/t | ~€3.50/t | ~€67.90/t |
| Steel, electric arc scrap (EAF) | ~0.5 | ~€35/t | ~€0.88/t | ~€16.98/t |
| Cement, Portland | ~0.83 | ~€58/t | ~€1.45/t | ~€28.13/t |
| Aluminium, primary (direct only) | ~1.5 | ~€105/t | ~€2.63/t | ~€50.93/t |
| Fertilizer, urea | ~2.5 | ~€175/t | ~€4.38/t | ~€84.88/t |
| Hydrogen, grey (SMR) | ~10.4 | ~€728/t H₂ | ~€18.20/t H₂ | ~€353.08/t H₂ |
| Hydrogen, green | ~0 | ~€0/t H₂ | ~€0/t H₂ | ~€0/t H₂ |
All figures use gross embedded emissions before Article 9 deductions. Net cost = Gross cost × CBAM factor. EU ETS price fluctuates.
The steel sector illustrates the bifurcation most clearly. The CBAM steel sector is the largest by import volume, with Turkey exporting approximately 6 million tonnes of steel to the EU annually, India approximately 3 million tonnes, and South Korea approximately 2 million tonnes. A Turkish blast-furnace steel exporter carries a gross embedded emissions cost of approximately €140/tonne but generates a net EU importer obligation of approximately €3.50/tonne in 2026, rising to approximately €67.90/tonne by 2030 as free allocation phases out.
Green hydrogen, by contrast, carries a CBAM cost of approximately zero at current measurement standards, establishing it as the most CBAM-advantaged product in the entire scope. Future exporters from Morocco, Chile, and Saudi Arabia developing green hydrogen capacity gain a structural zero-CBAM advantage over grey hydrogen producers in Russia and other gas-exporting economies.

CBAM Revenue, WTO Status, and the Broader Carbon Border Adjustment Landscape
EU CBAM generates revenue through certificate sales. The revenue distribution is established in Article 30 of Regulation (EU) 2023/956 and the EU Own Resources Decision: 75% of CBAM revenues flow to the EU budget as Own Resources, used to service NextGenerationEU recovery debt and capitalize the Social Climate Fund; 25% is retained by member states to cover national enforcement and administrative costs. The Commission's own projection estimates annual CBAM revenue of approximately €1.4 billion in 2028 (at 10% CBAM factor), rising to approximately €3–5 billion by 2030 as the factor reaches 48.5%.
The EU ETS price level directly determines certificate revenue. The Q1 2026 EU ETS price ranged from €66 to €90/tCO₂. Ten EU member states formally called the ETS an "existential risk" for strategic industries in January 2026, with Commission President von der Leyen signaling openness to Market Stability Reserve adjustments. Any ETS reform that reduces auction prices mechanically reduces CBAM certificate prices by the same proportion. CBAM has no independent price floor.
Russia filed WTO dispute DS639 against EU CBAM on May 12, 2025, alleging violations of GATT Article I (Most-Favored-Nation), Article II (tariff bindings), and the SCM Agreement. The EU declined consultations on May 22, 2025. India has informally signaled a formal challenge but has not yet filed. Turkey pursues a bilateral track, arguing the EU-Turkey Customs Union Agreement of 1995 exempts Turkish exports from CBAM treatment equivalent to that applied to other third countries. The WTO's non-functional Appellate Body means no enforced ruling is available within a realistic timeframe, though a WTO Panel could issue a report.
The EU's legal defense rests on GATT Article XX exceptions: Article XX(b) (measures necessary to protect human, animal, or plant life or health) and Article XX(g) (measures relating to conservation of exhaustible natural resources). WTO compatibility remains legally contested as of April 2026.
Who Needs to Act on EU CBAM Carbon Border Adjustment Requirements
Both EU importers and non-EU exporters face obligations or strategic consequences under the carbon border adjustment mechanism, though the legal obligations fall entirely on the EU side.
EU Importers: Complete Compliance Guide
EU importers of Annex I goods bear the full legal obligation under EU CBAM. The 4-step compliance pathway for authorized EU importers of CBAM goods covers authorization, emissions data collection, certificate management, and annual declaration. Importers who have not yet completed authorization face penalties of €300 to €500 per tonne CO₂e for each tonne of CBAM goods imported without authorization.
The complete compliance process, timeline, and documentation requirements are covered in the CBAM for EU importers guide, which includes the authorization application process, how to request embedded emissions data from non-EU suppliers, how to manage quarterly holdings before the February 2027 certificate sales begin, and how to file the September 30, 2027 declaration.
Does the De Minimis Threshold Apply to Electricity Imports?
No. Electricity (CN code 2716 00 00) and hydrogen (CN code 2804 10 00) are explicitly excluded from the de minimis threshold under Article 2(3a) of Regulation (EU) 2025/2083. Importers of any volume of electricity through physical interconnectors have full CBAM obligations regardless of annual mass.
Non-EU Exporters: Strategic Position and Data Requirements
Non-EU exporters carry no direct legal obligation under EU CBAM. The obligation rests on the EU importer. However, exporters who measure, verify, and transmit actual embedded emissions data to their EU customers enable those customers to avoid default value mark-ups (10% in 2026, rising to 30% from 2028) and potentially reduce their CBAM certificate costs below the default level. Exporters who refuse to provide data or cannot provide verified data force their EU customers to use punitive default values, creating a commercial pressure that effectively transfers CBAM compliance responsibility upstream.
The strategic options and data requirements for non-EU production installations shipping to EU customers are covered in the CBAM for non-EU exporters guide, including what emissions data is required, how to work with accredited verifiers, and how to evaluate the financial impact of the Article 9 deduction for exporters from countries with qualifying carbon pricing.
Is the UK CBAM the Same as the EU CBAM?
No. The UK CBAM takes effect January 1, 2027 and uses a tax-based mechanism rather than certificates, administered by HMRC under different sector coverage, different price methodology, and different calculation rules. UK exporters to the EU face full EU CBAM obligations; EU exporters to the UK face UK CBAM obligations from January 2027. The question of whether UK CBAM charges qualify for Article 9 deduction against EU CBAM obligations remains legally unresolved as of April 2026, creating a potential double-payment risk for goods in the UK-EU trade corridor.
What Is the Proposed Downstream Expansion of CBAM?
Commission proposal COM(2025)989, published December 17, 2025, proposes adding approximately 180 downstream steel- and aluminium-intensive products to CBAM scope from January 1, 2028. The proposed expansion covers vehicle parts and automotive components, white goods including washing machines and dishwashers, machinery containing steel or aluminium content, and other manufactured goods with significant embedded steel or aluminium, such as industrial radiators and heavy machinery. The proposal requires co-legislator approval through the ordinary legislative procedure (European Parliament and Council). Parliamentary and Council positions remain in formation as of April 2026.
EU steel and aluminium producers strongly support the downstream expansion as it closes the current loophole where goods made from CBAM-covered materials escape coverage. EU automotive and engineering industries oppose the expansion on grounds that complex multi-country supply chains make embedded emissions calculation prohibitively difficult. The what is the EU ETS guide explains the carbon price that underpins CBAM certificate costs, providing the context for how downstream expansion would amplify EU manufacturing sector cost pressures if passed.
Can an Authorized CBAM Declarant Lose Their Authorization?
Yes. Authorization can be revoked by the competent authority under IR 2025/486 if the authorized declarant fails to maintain the conditions that justified authorization, including sustained customs and tax compliance, accurate record-keeping under Article 6(6) (records must be kept until the end of the fourth year after the declaration year), or timely declaration and surrender obligations. Revocation triggers the unauthorized importer penalty rate of €300 to €500 per tonne CO₂e for any subsequent imports made before authorization is reinstated.

Will CBAM Prices Rise Through 2034?
Consensus analyst forecasts from 2024 to 2025 project EU ETS prices at approximately €80–100/tCO₂ by 2027 and approximately €100–150/tCO₂ by 2030 (consensus center approximately €126). If ETS prices follow the consensus trajectory while the CBAM factor simultaneously increases, the combined effect produces a compounding increase in net CBAM costs. BF-BOF steel net CBAM cost at a €126/tCO₂ ETS price in 2030 would reach approximately €122.36/tonne (2.0 × €126 × 48.5%), compared to approximately €3.50/tonne in 2026 at €70/tCO₂, representing a 35-fold increase in nine years. These projections carry significant uncertainty given the ETS reform discussions underway in early 2026.
