CBAM and Chinese Steel: Exposure, Calculation, and Compliance for the World's Largest Steel Exporter
China is the world's largest steel producer (over 1 billion tonnes/year) and the largest non-EU steel exporter to the EU after Türkiye. Major Chinese steel producers — Baowu (China Baowu Steel Group), HBIS (Hesteel), Shagang, Ansteel, Wuhan Iron and Steel — collectively account for the majority of Chinese steel exports to Europe. Chinese coal-dominant grid emissions and ageing BF-BOF capital stock mean actual embedded emissions typically run 2.10–2.40 tCO2/t — at or above the 2.18 EU default. CBAM is therefore not a "documenting actuals saves money" story for most Chinese integrated mills; it is a structural cost of doing business in EU markets that compounds as free CBAM allocation phases out from 2027.
Why Chinese Steel CBAM Exposure is Hard to Mitigate
For most Chinese integrated steel mills, the CBAM equation is structurally unfavourable: actual embedded emissions are at or above the EU default, the China ETS does not currently cover steel, and the China-EU price differential on the embedded carbon component is large. Specifically:
- Coal-dominant grid: Chinese national grid emission factor is approximately 0.85 tCO2/MWh — among the highest globally for major economies. This pushes actuals up across all sectors but particularly hits EAF steel where electricity is the dominant cost.
- Ageing BF-BOF stock: Many Chinese integrated mills built in the 2000s lag global best practice on coke rate, oxygen consumption, and energy efficiency. Modern Chinese mills (Baowu Zhanjiang, Shougang Caofeidian) approach global best practice; older mills do not.
- Limited carbon price offset: Without China ETS coverage of steel, there is no domestic carbon price to claim under CBAM Article 9.
- Hydrogen-DRI transition is years away: Baowu, HBIS, and others have hydrogen-DRI pilot projects but commercial scale is post-2030.
CBAM Steel Calculation for Chinese Mills
For Chinese BF-BOF steel exporting to the EU, the CBAM calculation per Annex III of Implementing Regulation 2023/1773 produces a specific embedded emissions value typically in the 2.10–2.40 tCO2/t range. See the full calculation guide.
For Chinese EAF steel (smaller share of production), actuals are lower (1.0–1.6 tCO2/t depending on scrap-DRI mix and grid factor) — but the coal-grid electricity hit limits how low they can go. Chinese EAF steel exporting to the EU does benefit from documenting actuals; Chinese BF-BOF integrated steel often does not.
Modern Chinese Mills with Better Actuals Story
Several modern Chinese installations have actual embedded emissions meaningfully below the 2.18 default and benefit from documentation:
- Baowu Zhanjiang Iron and Steel (Guangdong): 2010s-era integrated mill with modern coke ovens and BOF; actuals in the 1.85–2.05 tCO2/t range
- Shougang Caofeidian (Hebei): Relocated and modernised; similar profile
- HBIS Serbia (Smederevo): Operates in Serbia under HBIS Group; see also CBAM Serbia
- Tsingshan and various stainless steel producers: EAF-heavy production with documented actuals well below default
For these installations, the CBAM verification investment makes commercial sense.

Frequently Asked Questions
What is China's annual CBAM exposure on steel?
Estimated at EUR 1.5–4 billion annually depending on EU steel import volumes from China and certificate prices. China is among the top 3 non-EU CBAM-exposed countries by aggregate exposure.
Does China ETS reduce my CBAM cost on steel exports?
Not currently. China's national ETS does not yet cover steel — only power. Steel is scheduled to be added in later phases but the date is uncertain. Even when added, China ETS prices (~EUR 10–13/tCO2) are far below the threshold for CBAM Article 9 deduction.
Should Chinese integrated steel mills document actuals?
For most older BF-BOF mills with actuals at or above 2.18 default — no, documenting actuals would increase CBAM exposure. For modern integrated mills (Baowu Zhanjiang, Shougang Caofeidian) and for EAF mills with actuals meaningfully below default, yes — documentation captures real savings.
Which Chinese steel companies are most CBAM-exposed?
Baowu (China Baowu Steel Group, world's largest steel producer), HBIS (Hesteel), Shagang, Ansteel, and Wuhan Iron and Steel collectively account for the majority of Chinese steel exports to the EU.
How does CBAM affect Chinese vs Korean vs Japanese steel competitiveness?
Chinese steel faces the worst CBAM economics among major Asian exporters because of coal-grid electricity (vs Korea/Japan's mixed grid) and ageing BF-BOF stock (vs Korea's mostly modern integrated complexes). Korean and Japanese exporters have better actuals stories per tonne.
