CBAM cost for South Korea Hydrogen in 2026

Importing hydrogen from South Korea under the EU Carbon Border Adjustment Mechanism? Here is what one representative shipment costs on the official EU default value — and how much verified supplier data saves. All figures are produced by our compliance engine at the current published certificate price of €75/t.

How the South Korea hydrogen number is built

Under EU Regulation 2023/956 and its implementing rules, embedded emissions for hydrogen are the specific embedded emissions (SEE) of the good multiplied by the mass imported. Where you cannot yet provide verified actual data, the EU default value applies — and for hydrogen that default carries a 0.0% mark-up in 2026 (Regulation (EU) 2025/2621). This worked example uses the default SEE of 12.0 tCO₂e per tonne; verified data on this example brings the effective SEE to 12.0 tCO₂e per tonne, which is what removes the mark-up cost.

Two figures, both correct. Full exposure is what this shipment costs once EU ETS free allocation has gone (2034 onward) — the number to plan against. You surrender for 2026 is the actual 2026 obligation: free allocation still covers most of it, so only 2.5% of embedded emissions is chargeable this year (Art. 31, Reg (EU) 2023/956).

Illustrative single-product estimate. Verify with a full report before filing. CBAM liability also reflects any carbon price already paid in the country of origin (Article 9).

Default values are a regulatory fallback, not a measurement of any specific plant. The EU default SEE is a conservative reporting value that applies until you provide verified actual data — a real South Korea hydrogen plant may emit more or less. That is exactly why verified supplier data usually lowers the number.

Carbon price and Article 9 in South Korea

South Korea operates the K-ETS, so a carbon price already paid there may be creditable under Article 9 — keep the evidence of what was paid. Where a carbon price has been paid on these emissions, Article 9 of Regulation (EU) 2023/956 lets you deduct it from your CBAM liability — but only against evidence of the price actually paid, and it never turns a positive liability negative. This is separate from the default-value mark-up: verified emissions data removes the mark-up, while a verified carbon price paid in South Korea is what Article 9 credits.

Frequently asked

How much does CBAM cost for South Korea hydrogen?

For 2026 you surrender about €1,706 on the default value for 100 tonnes — 1,200 tCO₂e embedded at €75/t, of which only 2.5% is chargeable while EU ETS free allocation is still being phased out. Once it has gone the same shipment carries €68,232. Both include the 0.0% mark-up.

How much can verified supplier data save?

On this example, roughly €0 (0.0%) per shipment — removing the default mark-up brings the liability to €68,232.

When is CBAM payable on imports from South Korea?

Goods imported in 2026 become certificates bought from February 2027; the first annual declaration is due 30 September 2027.
