EU CBAM in 2026 — the complete guide for customs brokers and freight forwarders

The EU's Carbon Border Adjustment Mechanism entered its definitive period on 1 January 2026. Q1 certificate price is €75.36/tCO₂e. First annual surrender is due 31 May 2027. Here's what brokers and forwarders need to know to advise their clients — and to act as their Indirect Customs Representative.

Short version. The EU's Carbon Border Adjustment Mechanism entered its definitive period on 1 January 2026. Q1 certificate price is €75.36/tCO₂e, published 7 April 2026 by the European Commission. ~4,100 EU importers have authorised declarant status today; ~12,000+ applications are in flight. The first annual declaration is due 31 May 2027, the first certificate surrender from 1 February 2027. Penalty for non-compliance in the definitive period is 3–5× the certificate price per tonne CO₂e of unsurrendered emissions. This is a complete operational guide for customs brokers and freight forwarders advising their clients — including the path to acting as their Indirect Customs Representative.

What CBAM is (and isn't)

CBAM is a carbon-pricing import duty applied to embedded emissions — the CO₂e released during production of the imported good, calculated against country-of-origin and CN-code defaults. Importers buy CBAM certificates from the EU at the EU-ETS-linked price and surrender them annually. The mechanism equalises carbon costs between EU producers (who already pay ETS prices) and non-EU producers (who often don't), so EU industry decarbonisation isn't undercut by imports from less-regulated jurisdictions.

What CBAM is not:

Not a customs duty. Certificates are surrendered annually, not collected at the border. Customs releases the goods normally — CBAM compliance is a separate annual filing track against the importer's authorised-declarant account.
Not VAT. Different legal basis (Article 192 TFEU, climate measure), different administrator (the CBAM Authority + national NCAs), different timing.
Not yet covering all carbon-intensive imports. Six sectors only (cement, iron/steel, aluminium, fertilisers, electricity, hydrogen). Chemicals, polymers, glass, and other energy-intensive sectors will likely come into scope in later review cycles but aren't there yet.

Scope — what's in, what's out

Per Annex I of Regulation (EU) 2023/956, the six sectors in scope are identified by their Combined Nomenclature (CN) codes:

Cement — HS Chapter 25 (notably CN 2523 Portland cement and similar hydraulic cements).
Iron and steel — HS Chapters 72 and 73 (most ferrous metal products: ingots, bars, rods, sheets, tubes).
Aluminium — HS Chapter 76 (raw aluminium plus aluminium articles).
Fertilisers — HS Chapter 31 (mineral and chemical fertilisers, especially nitrogen-based).
Electricity — CN 2716 (cross-border power imports).
Hydrogen — CN 2804 1000 (industrial hydrogen).

The 50-tonne/year-per-importer threshold per Implementing Regulation (EU) 2025/2083 excludes very small importers (under 50t aggregated across all CBAM-scope CN codes annually). Above the threshold the full authorised-declarant + certificate-surrender regime applies.

Quick scope check for a specific CN code is on /cbam — the scope checker mirrors Annex I and surfaces the matching sector + your NCA contact in one click.

Authorised declarant status — the gating requirement

Only an authorised CBAM declarant may release CBAM goods into free circulation in the EU. The status is granted by your country's CBAM National Competent Authority (NCA) of the importer's country of establishment. Application requirements:

EU establishment (or a permanent representative who is established).
EORI number.
2-year customs compliance history.
In some member states: financial guarantee covering the largest expected single-year certificate liability.

The original application deadline was 31 March 2026. Most NCAs continue accepting applications, but processing time has stretched to 3–6 months. If you missed the deadline see our companion post: I missed the 31 March 2026 deadline — what now?

Importers who lack authorised status can either appoint an Indirect Customs Representative (ICR) who has it, or stop importing CBAM goods.

The certificate price and how it's calculated

Per Implementing Regulation (EU) 2025/2548, the CBAM certificate price is a derived weighted average of EU-ETS auction clearing prices, published by the European Commission. Critical: this is NOT the EU-ETS spot price. It's a smoothed average weighted by traded volume that the Commission publishes:

Quarterly during 2026 — Q1 2026 price was €75.36/tCO₂e, published 7 April 2026 (T+1 week after quarter end). Q2, Q3, Q4 follow the same cadence.
Weekly from 2027 onwards — every Monday, covering the prior week's auctions.

The authoritative feed lives at the EU's certificate-price page. Our system polls it daily; you can see the current price + period on the cost calculator.

The cost formula at a glance

For each CBAM-goods import, the certificate liability is roughly:

(direct emissions + indirect emissions if applicable) × tonnage
− free-allocation deduction (per the EU benchmarks)
× certificate price (€/tCO₂e)
− origin-country carbon price already paid (€)
= net certificate cost (€)

Each line has a regulation Article behind it. We have a full breakdown in the dedicated post: CBAM cost calculation explained — direct vs indirect emissions, free allocation, origin-country carbon credits, with one full worked example end-to-end.

Annual declaration and surrender

The first annual CBAM declaration is due 31 May 2027 and covers all 2026 imports. The declaration follows the field schema of Implementing Regulation (EU) 2025/2619 — per-CN-code totals, per-installation breakdowns, per-country totals, methodology used (verified vs default), and the carbon prices already paid in origin countries.

Certificate surrender follows the declaration. Importers must hold enough certificates, purchased from the CBAM Registry at the weekly/quarterly published price, to cover their net liability. Any shortfall triggers the Article 28 penalty (3–5× the certificate price per uncovered tonne).

From 1 February 2027 importers can start buying certificates. There's no stockpiling: certificates are tied to the period in which they were purchased and lose validity after the surrender deadline.

Verified vs default emissions values

The default values published by the Commission (per Implementing Regulation (EU) 2025/2621) are intentionally conservative — they err on the side of higher emissions to incentivise importers to source verified data from suppliers. Importers can use either:

Default values — country × CN-code emissions intensities from the Commission's "DVs as adopted" Excel. Includes statutory mark-up for definitive-period years (2026: ×1.0, 2027: ×1.05, 2028+: ×1.10 per the methodology). Always available, always higher than verified.
Verified values — emissions data audited by an accredited verifier per Delegated Reg (EU) 2025/2551. Lower than defaults in most cases (real production is usually cleaner than country-average defaults). Requires the supplier to commission a verifier — typical cost €5,000–€15,000 per facility per year.

For most importers the verified-values investment pays back at ~10,000+ tonnes/year of CBAM imports. Below that threshold defaults plus the certificate cost are usually cheaper than the verifier fees.

What brokers and forwarders do differently from in-house importers

If you're a customs broker or freight forwarder reading this, your job is fundamentally different from an in-house compliance team:

Multi-client throughput. One forwarder may handle CBAM compliance for 50–500 importer-clients. The unit economics require batch tooling and per-client subtotals.
Indirect Customs Representative (ICR) role. Many of those clients can't or won't get authorised declarant status themselves. They need an ICR — that's you. See the ICR workflow guide for the application process, pricing, and liability split.
Per-shipment cost reports. Your clients want a tamper-evident PDF showing the CBAM cost per shipment, with sources cited, that they can attach to their own customs-broker-vs-internal-finance reconciliation. Our paid PDF report is built for this exact use case.
Watchlists for tariff + price changes. ETS prices move; default values get updated quarterly; new sectors get added. Brokers running multi-client portfolios can't manually track all of it. (Watchlists for CBAM are on our 2026 roadmap.)

The implementing-acts package — your reading list

The EU published a 9-instrument package in December 2025 that operationalises everything above. The ones every advisor should read:

(EU) 2025/2550 — registry operation.
(EU) 2025/2546 — verification (accredited verifiers).
(EU) 2025/2547 — calculation methodology.
(EU) 2025/2620 — free-allocation deduction + benchmarks.
(EU) 2025/2621 — default emissions values.
(EU) 2025/2619 — customs data fields for the CBAM Registry.
(EU) 2025/2083 — 50t threshold.
Delegated (EU) 2025/2551 — verification principles.

Penalty exposure under Article 28

The definitive-period penalty is 3–5× the certificate price per tonne of unsurrendered emissions, set at the NCA's discretion based on intent and magnitude. At Q1 2026's €75.36/tCO₂e, that's €226–€377/t per missing tonne — easily 4–6× the cost of just buying and surrendering the certificate. Wilful non-compliance is fast ruin for any importer with meaningful CBAM volume.

For the transitional-period penalty regime (€10–50/t for missed quarterly reports between Oct 2023 and Dec 2025), see CBAM quarterly reports 2023–2025 — did you file all 9?

Your next move

Whether you're an importer or an advisor, the practical next steps look the same:

Run the scope check on your CN codes. /cbam tells you in-scope vs out-of-scope in one click and surfaces your sector + NCA.
Run the cost calculator on a representative shipment. Even ballpark numbers help size the 2027 surrender obligation.
Confirm declarant status (or appoint an ICR). If you're already authorised, double-check your account is in good standing. If not, see the missed-deadline post.
Lock in your data flow. 2026 imports get declared in May 2027. You need clean per-shipment data — CN code, origin, tonnage, supplier-verified intensities where available. Per-shipment cost reports + a permanent archive are what the CBAM calculator and /cbam/dashboard are built for; PRO subscribers get unlimited reports up to a monthly tax quota with active-subscription audit retention.

FAQ

What goods are in scope of CBAM?

Six sectors per Annex I of Regulation (EU) 2023/956: cement (HS Chapter 25), iron and steel (Chapter 72-73), aluminium (Chapter 76), fertilisers (Chapter 31), electricity (Chapter 27), and hydrogen (Chapter 28). Some downstream products are included where they incorporate significant CBAM-scope inputs. The full CN-code list lives in Annex I; we mirror it in our scope checker.

When does the first CBAM certificate surrender happen?

31 May 2027, covering 2026 imports. From 1 February 2027 importers can buy certificates from the CBAM Registry; pricing is the weekly weighted average of EU-ETS auction clearing prices per Implementing Regulation (EU) 2025/2548. Q1 2026 certificate price was €75.36/tCO₂e.

Is the 50-tonne threshold per shipment or per year?

Per importer per calendar year, aggregated across all CN codes within scope. Per Implementing Regulation (EU) 2025/2083, importers below 50 tonnes/year of CBAM goods are exempt from the declarant authorisation requirement. The threshold is generous enough that small importers shipping occasional samples are out of scope, but any meaningful commercial activity in cement / steel / aluminium / fertilisers crosses it quickly.

Are indirect emissions always included in the surrender obligation?

No — only for cement, fertilisers, electricity, and hydrogen per Implementing Regulation (EU) 2025/2547. For iron and steel and aluminium, indirect emissions are reported but not surrendered during the definitive period. The distinction matters because indirect emissions (i.e. electricity used to make the product) can be 30–50% of total embedded emissions for energy-intensive sectors.

Can I deduct a carbon tax I already paid in the country of origin?

Yes, per Article 9 of Reg 2023/956. If the producer paid a verifiable carbon price (UK ETS, China national ETS, Korea KETS, etc.) on the embedded emissions, that amount is deducted from the EU CBAM certificate liability. The proof requirements are strict — official tax-paid receipts in original-language with a certified translation. Our calculator accepts this as an optional input.
