CN 25233000 (Aluminous cement) is in CBAM scope. The largest current EU supplier is Turkey, at an EU default emission intensity of 1.95 tCO2e per tonne — which becomes 2.15 tCO2e in 2026 with the +10% statutory markup applied. For a typical 100-tonne shipment from Turkey, that translates to €16,165 in CBAM cost in 2026 and €19,104 in 2028 — an increase of €2,939 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 25233000 is from Japan — saving approximately €83 per 100 t versus the current top supplier Turkey at 2026 markup.

Where every euro goes — CBAM as % of landed cost

For a 100-tonne shipment of CN 25233000 from Turkey, CBAM is 65.0% of every euro you spend importing. By 2028 it grows to 68.7% as the EU markup phases to +30%.

Default Penalty Tax — what verified emissions could save you

Save up to 10,761 per 100 t with supplier-verified emissions at the EU benchmark intensity (Reg 2025/2620 §5.3). You're throwing €10,761to Brussels because you don't have data.

EU benchmark

Switching from EU defaults to supplier-verified emissions at the EU benchmark intensity could save up to 10,761 per 100 t shipment. Reg (EU) 2025/2620 §5.3 publishes the best-practice benchmark (route (1)); Reg 2025/2547 §3 lets you use your supplier's verified intensity in the calculator.
Calculate with verified intensity

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 Turkey's 2026 marked-up value.

What part of the CBAM bill is actually avoidable?

Of the 16,165 CBAM cost on a 100-tonne shipment of CN 25233000 from Turkey, 10,761 (67%) is avoidable with verified supplier data. The rest is the EU benchmark floor — physics, not penalty.

Benchmark floor

Unavoidable. What you pay even if your supplier matches EU best-practice intensity (Reg 2025/2620 §5.3 benchmark = 0.72 tCO₂e/t).

Data-availability gap

9,292

Avoidable if your supplier's actual intensity is below the EU default (1.95 tCO₂e/t). Verified data beating default closes this gap.

Markup penalty

1,470

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.

Hidden opportunity — procurement angle

💡 Switching from Turkey to Japan pays off if their goods premium stays under 1.1%. Competitors paying defaults are 1.1% more expensive at the customer — that's a marketing weapon, not just compliance.

Show year-by-year tolerance bars

Top current supplier of CN 25233000: Turkey (EU default 1.95 tCO₂e/t). Lowest-default-intensity CBAM-eligible alternative: Japan (EU default 1.94 tCO₂e/t).

Threshold, not claim: we compute the maximum goods-price premium for Japanwhere 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 Japan's default. Run with verified data when available.

📨 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 25233000)
  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.

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 25233000 (Aluminous cement)

Is CN 25233000 (Aluminous cement) in CBAM scope?

Yes. CN 25233000 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 25233000?

The European Commission publishes country-specific default emission values for CN 25233000 under Implementing Regulation (EU) 2025/2621. Across CBAM-eligible non-EU origins, the published range is 1.94 tCO2e per tonne (Japan — lowest published default) to 2.29 tCO2e per tonne (India — 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 25233000 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 (€16,082 per 100 t), Turkey (€16,165 per 100 t), China (€18,071 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 25233000?

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.
