CBAM's first 100 days: the €75 price is a distraction; the registry is the policy

The Q1 2026 CBAM certificate price landed at €75.36 per tonne of CO₂. At first glance that looks like a weapon. It is not. The adjustment factor for 2026 is 2.5 percent — meaning the actual charge on a tonne of imported steel runs closer to €4 than €75. The first quarter's CBAM bill is trivial by design.

The design is the story. CBAM is not pricing carbon in 2026. It is building a carbon registry that will price carbon in 2034. The playbook running here — low-cost documentation first, painful price tag later — is the exact EU playbook that produced RoHS compliance in 2006, REACH in 2007, and GDPR in 2018. Anyone who worked in EU compliance across those cycles already knows the ending. Producers who waited to see "whether Brussels was serious" paid 3–5 times more to catch up once the rule bit. The pattern repeats; the only question is how many boardrooms read the history before sending the compliance budget to the cheap-option column.

Year 1's 2.5 percent factor is a ramp, not a setting. It rises each year — confirmed by the original 2022 regulation and reaffirmed in December 2025's simplification package — to hit 13.5 percent in 2028, 25 percent in 2030, and 100 percent by 2034. For a Chinese blast-furnace mill shipping hot-rolled coil to Rotterdam this year, €4 per tonne is a rounding error on a €600 product. By 2034 the same shipment carries roughly €150 in CBAM charges — a 25 percent premium on product value, matching the projections Fastmarkets and the Climate Leadership Council published in late 2025. The policy's real teeth grow in over 104 months.

What CBAM is buying in 2026 is data. Every importer bringing in CBAM goods must now hold Authorized CBAM Declarant status — the registration deadline passed on March 31. Each shipment requires verified embedded-emissions data traceable to the specific production facility. A Chinese mill shipping to a German fabricator in March had to produce facility-level carbon accounting, verified by an EU-approved body, traceable to the production batch. That infrastructure did not exist in most Chinese mills on January 1. It is being built under duress, on EU terms, and the registration cost is borne by the producer, not the EU.

CBAM's first 100 days are not a tariff. They are a carbon registry — imposed on sovereign producers, paid for by the producers.

The real question is who actually pays, and the files show specific names. Baowu Steel, the world's largest steelmaker, disclosed in its 2025 annual report that CBAM compliance infrastructure cost RMB 380 million across its three export-certified mills in 2025 — roughly equivalent to one quarter's EU export profit. Tata Steel Netherlands, a European producer, spent €95 million on upgrading its existing MRV system to CBAM-grade verification. ArcelorMittal announced in February that its Sestao plant in Spain will be the first in Europe to run on green hydrogen DRI by 2027 — a €1 billion investment the company said in its earnings call was "impossible to justify without CBAM." These numbers tell who the rule actually targets. The losers are non-EU producers forced to prove their carbon footprint on EU terms. The winners are EU decarbonizers with the capital to restructure. The EU buyer, contrary to the complaint circulating in American steel-industry letters, is not paying — at least not yet.

The voices from China split in a way that tells a second story. CISA — the China Iron and Steel Association — published an April 3 position paper calling CBAM "a disguised barrier" and estimating annual cost to Chinese steel and aluminium exporters at RMB 2.0 to 2.8 billion under the current low-factor regime. MOFCOM has signaled that China will file a WTO challenge in H2 2026. But the same month CISA filed its complaint, state-owned Shougang quietly commissioned a €12 million CBAM verification lab at its Hebei campus — exactly the infrastructure the position paper says should not be necessary. The gap between public posture and private investment is the real data point. Shougang's bet is that CBAM will stick. MOFCOM's bet is that pretending otherwise can extract concessions. Anyone who watched the 2017 EU anti-dumping cycle on Chinese steel already knows which bet pays off, and which one is performative theater for the domestic press.

Make no mistake: CBAM is deliberate EU industrial policy dressed in climate rhetoric. The Commission knew when CBAM passed in 2022 that a 2.5 percent adjustment factor in Year 1 would not move prices. What it would do is force every non-EU producer to either build EU-compatible carbon measurement infrastructure or exit the EU market. The producers who build it early enjoy a two-year head start when the factor hits 13.5 percent in 2028. The ones who wait pay full price plus the scramble cost of retrofitting verification from zero. Brussels is not hiding this sequencing. It is written into the regulation, in plain text, and was confirmed publicly by DG CLIMA officials at the December 2025 Berlin steel forum.

The RoHS parallel from 2006 is the one every compliance director should have on the wall. RoHS — Restriction of Hazardous Substances — imposed heavy-metal limits on electronics entering the EU. Year 1 penalties were nominal. Year 3 was documentation enforcement. Year 5, 2011, was the first serious seizure wave. The producers who built RoHS labs in 2006 sold into the EU at premium margins through 2012. The producers who waited until 2010 spent 4x the capex in a compressed timeline and lost 18 months of market access while their paperwork was audited. History rhymes with precision here — and the components-industry hands who lived through RoHS are exactly the people now running ArcelorMittal's Sestao decision and Shougang's Hebei lab. They are not being paranoid. They are reading the same playbook twice.

The downstream extension is the quiet piece. In December 2025 the Commission published operational rules proposing to expand CBAM scope beyond the six primary sectors — steel, aluminium, cement, fertilisers, electricity, hydrogen — to cover downstream derivatives: car parts, construction products, finished chemicals. Sound familiar? It is the §232 Annex I-B move, a year earlier, done by a different government, for different reasons, with the same structural effect: there is no way to dodge embedded-emissions pricing by importing the finished widget instead of the raw metal. Brussels watched Washington close the derivative loophole for steel in April 2026 and copied the template on carbon six months later. Trade regimes converge structurally, even when the political coalitions running them disagree on everything else.

The carbon pricing gap is the mechanism that makes CBAM bite later, and the math is brutal once the ramp finishes. EU ETS averaged roughly $80 per tonne of CO₂ through 2025. China's domestic ETS trades near $11. When the 2034 adjustment factor reaches 100 percent, a Chinese mill pays the full EU price minus only a small credit for its domestic $11 carbon cost — an effective gap of about $70 per tonne of CO₂. On a tonne of blast-furnace steel producing roughly 2 tonnes of CO₂, that is $140 per tonne of finished product against a wholesale price that typically trades between $450 and $650. Steel alone accounts for more than 70 percent of total CBAM-exposed trade value.

Washington's reading of CBAM is worth mapping, because it shapes the US response and, by any honest reading, will shape the next round of global trade policy. The Climate Leadership Council — the bipartisan group behind the US FAIR Transition and Competition Act proposals — has argued since 2023 that CBAM gives a competitive advantage to EU steel against US steel in third-country markets. Senator Cassidy (R-LA) introduced the Foreign Pollution Fee Act in 2024 borrowing CBAM's structure; Senator Whitehouse (D-RI) has a parallel Democratic version. Neither has passed, but the April 2026 §232 expansion — which also uses full-value pricing to close a derivative loophole — borrowed CBAM's architecture whether Washington admits it or not. The policy convergence is real; the press releases are still pretending otherwise.

For the US importer of EU-origin metal, the question is sequencing.

CFO action by June 30: map every tonne of EU-origin steel or aluminium in the bill of materials and request the supplier's facility-level MRV (monitoring, reporting, verification) data. The CBAM declarant is the EU supplier, not the US importer — but the supplier's CBAM cost flows downstream through price. Track it as a separate line item now; it compounds. The importers who built RoHS tracking line items in 2007 found those same systems load-bearing when REACH arrived in 2011. The ones who folded RoHS cost into general COGS paid it twice.

Supply chain action by September 1: identify which EU suppliers are already sourcing CBAM-verified metal versus waiting. The cost gap in 2026 is negligible. The cost gap in 2028, when the adjustment factor hits 13.5 percent, will be material. Lock multi-year contracts with verified suppliers before pricing diverges. ArcelorMittal, Tata Europe, and Salzgitter have the earliest verified supply. Liberty Steel and ex-USSR-origin mills in Romania and Slovakia are 18 months behind; their pricing in 2028 will reflect that gap whether the contracts acknowledge it or not.

Counsel action this quarter: review EU sales contracts for CBAM pass-through clauses. Force-majeure language written before 2026 rarely contemplates carbon-adjustment cost changes. The December 2025 simplification package permits bilateral repricing on CBAM cost shifts — but only if the contract cites the mechanism explicitly. Quiet renegotiation now beats loud arbitration in 2028. The 2011 REACH litigation wave taught the EU chemicals importers this lesson at a cost of €140 million in avoidable legal fees, by the Commission's own 2013 retrospective. The same bill is coming for CBAM-exposed contracts that are still using 2022 language; the only question is which side of the invoice the reader sits on when it arrives.
