The carbon price now travels with the goods.
On 1 January 2026 the EU Carbon Border Adjustment Mechanism stopped being a reporting exercise. Importers of steel, aluminium, cement, fertilisers, electricity and hydrogen buy certificates at the EU carbon price and surrender them. Korea is the third-largest non-EU steel supplier to the bloc. This page is a working diagram of that machine — and of what Seoul and the mills are doing at the same stations.

- EU CBAM and Korean steel exports
Background
CBAM is not a tariff. It mirrors the carbon cost the EU ETS puts on a mill inside the Union when the same good crosses the border. The Q2 2026 certificate price is €75.28 per tCO₂e. The first surrender is 30 September 2027, for 2026 imports. Free allocation falls from 97.5% in 2026 to zero in 2034. Emissions above the EU benchmark are charged in full from year one.

Goods move left to right. The black line is the carbon cost that travels with them. In 2026, 2.5% of the EU benchmark is charged; the amount above the benchmark is billed in full from the start.
01 — Carbon leakage
Without a border, carbon only moves.
An EU mill already pays under the ETS. If the same hot-rolled coil arrives without that cost, production and emissions shift to the cheaper coast. CBAM asks the importer for the difference. Toggle the mechanism and compare the two ledgers.
Duisburg · EU ETS
EU mill
€14/t
1.45 tCO₂e embedded
- Free allocation1.27 t
- ETS charge0.18 t
It still pays the ETS. Free allocation falls on the same schedule as CBAM, so the domestic bill and the import bill line up.
Pohang · K-ETS, then CBAM
Korean mill
€61/t
2.13 tCO₂e embedded
- Free allocation1.27 t
- K-ETS deduction0.05 t
- CBAM charge0.81 t
The EU importer now pays CBAM on this tonne. K-ETS already paid is deducted, but the effective price is about €1.9/t, so it barely nicks the EU price.
2026 example, 1 t hot-rolled coil. EU mill 1.45 tCO₂e/t, Korean BF-BOF 2.13 tCO₂e/t. Certificate €75.28. The Korean furnace’s excess over the 1.30 benchmark is billed in full from 2026.
02 — How it runs
Seven steps from a Korean furnace to an EU certificate.
Press a station. The left column is how CBAM actually moves; the right is what Seoul and the firms do at the same point. Play walks the cargo through the sequence.
How CBAM works
A carbon price on the goods, not the factory
CBAM does not tax Korean plants. It prices the greenhouse gases already embedded in selected goods the moment they enter the EU customs territory — mirroring what an EU mill pays under the EU ETS.
- Six sectors at launch: iron & steel, aluminium, cement, fertilisers, electricity, hydrogen.
- Certain precursors and downstream articles in those chains are also listed.
- Iceland, Liechtenstein, Norway and Switzerland are exempt (Annex III) because they already sit inside, or are linked to, the EU ETS.
- A 50-tonne-per-year mass threshold (Omnibus 2025) drops most small importers; electricity and hydrogen have no de minimis.
How Korea prepares
Steel is the exposure
The EU takes about €3.6 billion of Korean steel a year (3.38 Mt in 2024) — the third-largest non-EU supply. Roughly 70% of Korean crude steel still runs through coal-based blast furnaces, so the carbon intensity arriving at Rotterdam is high.
- POSCO, Hyundai Steel and Dongkuk Steel account for most of the tonnage.
- MOTIE’s steel plan pushes the industry toward high-value and low-carbon routes as CBAM and US tariffs hit together.
- RMI puts US$36–70 billion of Korean steel value at risk from CBAM between 2026 and 2050 if the furnace mix does not change.
- Parliament voted in September 2026 to pull more finished steel and aluminium goods into scope — a second wave for downstream exporters.
03 — Scope
Six sectors. For Korea, almost all steel.
CBAM follows carbon-leakage sectors with high emissions and high trade. Open a sector to see Korea’s EU mix. Shares are Korea’s composition, not the EU’s import mix.
Steel
Korea’s share of its CBAM exports: ≈ 89%
Korea’s CBAM story. Flat-rolled, wire, tubes and structural steel under CN chapters 72–73. Direct emissions only.
- Intensity
- BF-BOF ~2.0 tCO₂e/t · EAF scrap ~0.5
- Korea
- €3.6bn / 3.38 Mt to the EU (2024). POSCO, Hyundai Steel, Dongkuk.
On 15 September 2026 the European Parliament voted to pull finished goods such as fasteners, wire, springs and household aluminium into scope. Auto parts and appliance suppliers are now in the briefing room.
04 — The invoice
The real cost of a Korean tonne of coil in 2026.
Certificates surrendered = max(0, embedded − free-allocation adjustment − carbon already paid ÷ CBAM price) × mass. The year rail at the top feeds this sum. Switching BF-BOF, EAF and HyREX is why furnace mix is strategy.

05 — Seoul and the mills
Fifteen measures, a mature ETS, and the blast-furnace problem.
Korea cannot negotiate CBAM away. What remains is data, Article 9 paperwork, and changing the iron. The government is moving fast on the first two. The third is a decade of capital.

Who moves
Three mills carry almost all of the EU tonnage. The rest of the chain is now finding out it is inside CBAM too.
BF-BOF majority · HyREX
POSCO
Korea’s largest mill and the name EU buyers associate with Korean coil. Product-level HRC footprint under CBAM boundaries sits around 2.13 tCO₂e/t — well above the EU benchmark of 1.30 — so a large slice of every tonne is charged from 2026, not 2034. HyREX, its hydrogen DRI project, is the structural answer: pilot in 2028, roughly 2.5 Mt of commercial ambition by 2035, target intensity near 0.33 tCO₂e/t.
Article 9 · K-ETS
The conditions are there, recognition is pending, and the deduction is small.
A legally binding K-ETS since 2015 covers steel and cement and has no export rebate, which is why Korea is among the strongest Article 9 candidates. The third-country carbon-price implementing act was consulted in May–June 2026 and had not been adopted by July. Even if recognised, free allocation inside K-ETS means the deductible effective price is a few euros, not seventy.
What comes next
The wall is still being built.
- 1 Feb 2027 — certificate sales open.
- 30 Sep 2027 — first surrender, for 2026 imports.
- 2026–34 — free allocation 97.5% to 0%. The invoice follows that line.
- Downstream — 15 Sep 2026 Parliament voted to pull finished steel and aluminium goods into scope. Parts firms entered the briefing.
Figures are worked examples from public 2026 sources: Regulation (EU) 2023/956 as amended by 2025/2083, late-2025 implementing acts, Q2 2026 certificate price €75.28/tCO₂e, Directive 2003/87 Art. 10a CBAM factor, Korean joint-government briefings and the February 2026 15-measure package, KCCI/KICOX exporter survey (Aug 2026). The K-ETS effective price and POSCO-class HRC intensity (~2.13 tCO₂e/t) are a model, not an official notice. Article 9 recognition of K-ETS was pending as of mid-2026.
