South Korea operates the most advanced carbon pricing scheme of any major CBAM-affected exporter — making it the leading Art. 9 deduction candidate globally.
South Korea exports significant volumes of flat-rolled steel, structural sections, and aluminium semi-fabricated products to the EU. POSCO and Hyundai Steel are the principal steel exporters. South Korea's steel default (2.12 tCO₂e/t semi-finished, BF-BOF) is moderate; its aluminium default (0.36 tCO₂e/t secondary route) reflects a scrap-based production profile.
Carbon pricing in South Korea: South Korea's K-ETS (Korea Emissions Trading Scheme) has been active since 2015 — the longest-running national ETS among major CBAM-affected exporters. The K-ETS covers steel, cement, and other CBAM-relevant sectors with legally binding, verified carbon pricing.
South Korea's K-ETS is the most advanced Art. 9 deduction candidate of any non-EU country. The scheme covers CBAM-relevant sectors with legal enforcement and verified carbon prices. However, no country has received formal European Commission confirmation of Art. 9 eligibility as of April 2026. Korean exporters should document carbon prices paid under K-ETS per tonne of embedded emissions — this documentation will be essential when Commission recognition is confirmed.
Korean exporters have a two-part cost advantage: K-ETS prices paid domestically may be deductible from CBAM certificate obligations once recognised, and Korean aluminium (secondary route, 0.36 tCO₂e/t) is well below the SEFA benchmark — meaning zero certificate liability for secondary aluminium regardless of Art. 9 status.
