South Korea — CBAM Guide

South Korea operates the most advanced carbon pricing scheme of any major CBAM-affected exporter — making it the leading Art. 9 deduction candidate globally.

Trade Profile

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.

Article 9 — Carbon Price Deduction

Partial / Pending

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.

Compliance Insight for South Korea Exporters

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.

Four Steps to Compliance

1
Register in the CBAM Operators Portal
Upload installation identification data: legal name, UN/LOCODE, GPS coordinates, contact person. This enables your EU buyer's authorised declarant to access your verified data.
2
Establish a monitoring plan
Document all energy inputs, production outputs, and emission calculation methodology per the governing EU implementing regulation. This is the foundation for any verified data submission.
3
Engage an accredited verifier
Appoint a third-party verifier accredited under EN ISO/IEC 14065 by an EA-recognised National Accreditation Body. A physical site visit is required before verified data can be submitted.
4
Share verified data with your EU buyer
Provide verified specific embedded emissions to your EU buyer's authorised CBAM declarant before the September 2027 declaration deadline. Verified actual data replaces default values — typically at significantly lower cost.
