First annual CBAM declaration is due 30/09/2027. Document your Hydrogen imports from China now.
EU default-value mark-up is +10% in 2026 and rises to +20% in 2027 per Implementing Reg (EU) 2025/2621. Switching to supplier-verified emissions skips the mark-up entirely — but you need verified figures before the higher rate kicks in. Calculate your exposure today, share the results with your supplier, and lock in lower CBAM cost for the year ahead.

Importing Hydrogen from China? Here's what CBAM costs you today.
100 tonnes of CN 28041000 from China
By 2028 the same shipment costs €260,987 as the EU markup increases (Reg 2025/2621 §3 phases +10% → +20% → +30%). Your shipment may differ — yours may have lower verified emissions.
Calculated at the current CBAM certificate price of €75.36/tCO₂e × the EU default emission intensity for China (Reg 2025/2621). Landed-cost ratio uses Eurostat Comext market price (DS-045409).

CN 28041000 (Hydrogen) is in CBAM scope. The largest current EU supplier is China, at an EU default emission intensity of 26.64 tCO2e per tonne — which becomes 29.30 tCO2e in 2026 with the +10% statutory markup applied. For a typical 100-tonne shipment from China, that translates to €220,835 in CBAM cost in 2026 and €260,987 in 2028 — an increase of €40,152 per shipment as Reg 2025/2621 §3 phases the markup from +10% to +30%. Among CBAM-eligible origins with published EU defaults, the lowest CBAM cost for CN 28041000 is from Kazakhstan — saving approximately €131,141 per 100 t versus the current top supplier China at 2026 markup.
Where every euro goes — CBAM as % of landed cost
For a 100-tonne shipment of CN 28041000 from China, CBAM is 45.9% of every euro you spend importing. By 2028 it grows to 50.1% as the EU markup phases to +30%.
By 2028 (peak markup phase, +30%)
“Landed cost” here = goods value (Eurostat Comext €/kg × 100 t) + CBAM cost (EU 2026 marked-up default × current cert price). Excludes freight, transmission losses, market premiums — those vary per importer. Source data from cbam_comext_partner_facts × cbam_country_defaults × cbam_certificate_prices.

3 questions every CBAM declaration faces
Every PDF you generate for CN 28041000answers all three with cited regulation refs. That's the difference between a calculator output and an audit-ready document.
Show the three cards
Where did the data come from?
Live from Eurostat Comext (DS-045409), refreshed weekly via thecbam-comextcron. Refresh timestamps tracked in cbam_source_runs.
Can it be verified?
Every PDF carries a SHA-256 hash + QR code linking to a public verify page (verification methodology). Auditors trace any figure back to its EU regulation citation in the PDF footer.
What if EU updates the defaults?
Our cron tracks cbam_country_defaults weekly. PDFs you bought stay valid (snapshot of values at purchase time); the calculator uses the latest. PRO subscribers get an audit-log JSON recording every figure's timestamp.
Default Penalty Tax — what verified emissions could save you
Save up to €182,484 per 100 t with supplier-verified emissions at the EU benchmark intensity (Reg 2025/2620 §5.3). You're throwing €182,484to Brussels because you don't have data.
Show the 2-bar comparison
The benchmark is the EU's best-practice reference, not a guarantee. Your supplier's actual verified intensity may be higher or lower than the benchmark — but in most cases it's materially lower than the marked-up default. Default leg uses China's 2026 marked-up value.
What part of the CBAM bill is actually avoidable?
Of the €220,835 CBAM cost on a 100-tonne shipment of CN 28041000 from China, €182,484 (83%) is avoidable with verified supplier data. The rest is the EU benchmark floor — physics, not penalty.
Benchmark floor
€38,351
Unavoidable. What you pay even if your supplier matches EU best-practice intensity (Reg 2025/2620 §5.3 benchmark = 5.09 tCO₂e/t).
Data-availability gap
€162,408
Avoidable if your supplier's actual intensity is below the EU default (26.64 tCO₂e/t). Verified data beating default closes this gap.
Markup penalty
€20,076
Avoidable by getting any verified data — Reg 2025/2621 §3's +10/+20/+30% statutory uplift only applies to defaults, not verified emissions.
The action: get one document from your supplier — a verifier-stamped emission statement per Reg 2025/2547 §3. That single document collapses the amber + red segments into the green floor.
Sources: cbam_benchmarks for the EU best-practice intensity (Reg 2025/2620 §5.3); cbam_country_defaultsfor per-origin default intensity + 2026 marked-up value (Reg 2025/2621 §3); current cert price. “Avoidable” means via verified supplier data, not via origin-switching or any commercial route.

Hidden opportunity — procurement angle
💡 Switching from China to Mali pays off if their goods premium stays under 100.4%. Competitors paying defaults are 100.4% more expensive at the customer — that's a marketing weapon, not just compliance.
Show year-by-year tolerance bars
Top current supplier of CN 28041000: China (EU default 26.64 tCO₂e/t). Lowest-default-intensity CBAM-eligible alternative: Mali (EU default 0.00 tCO₂e/t).
Tolerance grows yearly — every markup phase makes the lower-default origin more competitive on landed cost.
Compare both origins side-by-side in the calculatorThreshold, not claim: we compute the maximum goods-price premium for Maliwhere switching still saves money. We don't have visibility into your supplier negotiations; the actual quoted premium varies by supplier and contract.
EU defaults are conservative: your existing supplier's verified emissions may already be at or below Mali's default. Run with verified data when available.

📨 We'll write the letter for you — legal-grade, in Chinese, citing Reg 2025/2547 §3 verbatim. Free, email-delivered. No competitor offers this; consultancies charge €5,000+ for equivalent letters.
See what the letter requests + how it works
What the letter asks for (exactly the 6 inputs Reg 2025/2547 §3 entitles you to request from the producer):
- Direct emission intensity (tCO₂e per tonne of CN 28041000)
- Indirect emission intensity (tCO₂e per tonne)
- Production route (e.g. blast furnace / electric arc furnace for steel)
- Aggregated parameter for input materials (precursors)
- Verifier statement per §6 (EA-recognised verifier)
- Statement of carbon price already paid in country of origin (Reg 2023/956 Art 9 deduction support)
How it works: fill in your supplier's name + email + your company details + annual import volume. We generate a tamper-proof PDF + email-ready text and email it to YOU (not your supplier directly) — you stay in control of the relationship.

Origin carbon-price deduction (Article 9)
Article 9 of Regulation (EU) 2023/956 lets importers deduct any verified carbon price already paid in the country of origin from the CBAM certificate cost. If your Chinasupplier participates in a domestic ETS or carbon-tax scheme and can produce verifier-attested proof of payment, you enter the €/tCO₂e in the calculator's Origin carbon price paid field and the deduction is applied to the gross cost.
We do not publish a live table of China's domestic carbon prices on this page — the value depends on the specific scheme + verification, not a public daily print. Speak with your supplier and provide the verified figure to the calculator yourself.

Frequently asked: CBAM imports from CN 28041000 (Hydrogen)
Is CN 28041000 (Hydrogen) in CBAM scope?
Yes. CN 28041000 is classified under the hydrogen sector in CBAM scope per Annex I of Regulation (EU) 2023/956. EU importers of this CN code must comply with CBAM reporting obligations from January 2026 (definitive period). Verify scope status with our cn-scope monitor cron, refreshed weekly.
What is the EU default emission intensity for CN 28041000?
The European Commission publishes country-specific default emission values for CN 28041000 under Implementing Regulation (EU) 2025/2621. Across CBAM-eligible non-EU origins, the published range is 0.00 tCO2e per tonne (Mali — lowest published default) to 26.64 tCO2e per tonne (United States — highest published default). The 2026 marked-up value adds +10% per Reg 2025/2621 §3, phasing to +20% in 2027 and +30% from 2028.
Where can I import CN 28041000 most cheaply (CBAM cost)?
By 2026 marked-up EU default emission intensity × current CBAM certificate price (€75.36/tCO2e), the lowest CBAM cost per 100-tonne shipment comes from: Kazakhstan (€89,693 per 100 t), North Macedonia (€89,693 per 100 t), Brazil (€89,693 per 100 t). This ranks origins by EU-published default intensity only — your supplier's verified emissions may put any origin lower. Run the calculator at /cbam/calculator with your specific shipment for an exact comparison.
Can my supplier's verified emissions reduce my CBAM cost on CN 28041000?
Yes. Per Implementing Regulation (EU) 2025/2547 §3, an importer can substitute the EU default emission intensity with a supplier-verified figure. The verified figure must come from an EA-recognised verifier per Reg (EU) 2025/2546 (verification of declared embedded emissions). For most imports the verified intensity is materially lower than the default + statutory markup, so getting verified data from your supplier reduces CBAM cost. Article 9 of Regulation (EU) 2023/956 also lets you deduct the carbon price already paid in the country of origin from the CBAM surrender obligation, with verified documentation.
