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.

3 questions every CBAM declaration faces

Every PDF you generate for CN 25232900answers 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.

Where on the map does CN 25232900 hurt your CBAM bill the most?

Origins coloured by EU default intensity. Greener origins cut both CBAM cost and audit complexity — less to verify, fewer surprises in your data.

Show the 15-origin grid

Origins in green have ~8% lower EU default intensity than red-zone origins. Importing from a green-zone supplier can cut your CBAM cost AND reduce audit complexity (fewer EU-accredited verifiers operate in red-zone countries — industry rule of thumb, not regulatory).

Don't know how to ask your supplier for emission data?

📨 We'll write the letter for you — legal-grade, in Turkish, 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):

  1. Direct emission intensity (tCO₂e per tonne of CN 25232900)
  2. Indirect emission intensity (tCO₂e per tonne)
  3. Production route (e.g. blast furnace / electric arc furnace for steel)
  4. Aggregated parameter for input materials (precursors)
  5. Verifier statement per §6 (EA-recognised verifier)
  6. 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.

Letter content cites EU regulations verbatim; no fabrication. Turkishtranslation available alongside the English version. Disclaimer in the letter: “Translation in good faith; English version prevails.”

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 Turkeysupplier 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 Turkey'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 25232900 (Grey Portland cement)

Is CN 25232900 (Grey Portland cement) in CBAM scope?

Yes. CN 25232900 is classified under the cement 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 25232900?

The European Commission publishes country-specific default emission values for CN 25232900 under Implementing Regulation (EU) 2025/2621. Across CBAM-eligible non-EU origins, the published range is 0.85 tCO2e per tonne (Ethiopia — lowest published default) to 1.49 tCO2e per tonne (Mongolia — 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 25232900 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: Japan (€7,378 per 100 t), Tunisia (€7,544 per 100 t), Albania (€7,709 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 25232900?

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.
