CBAM Calculator - CBAM Certificate Cost & Default Values

CBAM calculator: estimate how many EU CBAM certificates an import needs and what they cost in EUR, from the official default values. $1 per 1,000 lines.

Estimate how many EU CBAM certificates an import needs and what they cost in EUR. Give it a CN/TARIC code, a country of origin and the net mass in tonnes. The calculation uses the official default values, CBAM benchmarks and quarterly CBAM certificate prices published by the European Commission.

All official tables are bundled into the Actor, with their version, source URL, retrieval date and SHA-256 hash. Runs make no outside web requests, so they are fast (about 1–4 s), cheap, and give the same answer every time. Every result line shows which dataset version and date it used.

⚠️ Not legal or tax advice, and not legally binding. This is an informational estimate based on the default-value method. Only the acts published in the Official Journal of the European Union are authentic. The Commission's Excel files state that they are informational. Your real obligation depends on your CBAM declaration, verified actual emissions, any carbon price you can evidence, and your competent authority. Check with a customs or CBAM adviser.

What it does

For every import line, the Actor:

1. Finds the default value. It matches the CN code (longest prefix) in the country's table of Annex I to Implementing Regulation (EU) 2025/2621, as corrected by Implementing Regulation (EU) 2026/1740 (Commission file v2, 6 Aug 2026).
   • If the country has no table, or its value is "–", it uses "Other countries and territories".
   • With precursorUnknownOrigin it uses Annex IV.
   • The "total" column is used. Indirect emissions are N/A for steel, aluminium and hydrogen.
2. Adds the phase-in mark-up printed in the Annex:
   • cement, iron & steel, aluminium and hydrogen: 10% / 20% / 30% for 2026 / 2027 / 2028+;
   • fertilisers: 1%.
3. Subtracts the free allocation adjustment. This is the CBAM factor × CSCF × the Column B benchmark (point 5 of the Annex to Implementing Reg. (EU) 2025/2620), for the production route of the default-value row.
   • CBAM factor: 0.975 in 2026, 0.95 in 2027, 0.90 in 2028 … 0 in 2034.
   • CSCF: 100% for 2026–2030 (Implementing Decision (EU) 2026/1862).
4. Multiplies by tonnes, and optionally deducts the carbon price paid in the country of origin.
5. Prices the certificates at the official quarterly price for the quarter of the import date. You can also supply your own price.
   • If the quarter's price has not been published yet, the Actor uses the latest published price and sets certificatePriceIsEstimate: true.

Conservative choices. These are always explained in notes:

• A code that is less specific than the table uses the highest sub-code default value.
• An ambiguous benchmark (several routes) uses the lowest benchmark.

Special statuses:

Status	Meaning
exempt_country	Origin in IS, LI, NO or CH (Annex III of 2023/956).
eu_origin	Origin in an EU Member State.
not_cbam_good	The code is not in the CBAM tables. The note suggests valid 2026 CN codes where the heading has CBAM goods.
unsupported	Electricity (2716).
error	Invalid input. Not charged.

Pricing

Pay per event:

• $0.00005 per run start, plus
• $0.001 per calculated line ($1 per 1,000 lines).

Invalid lines (status: "error") are free. A 5-line run costs about $0.005.

Limits and FAQ

• Up to 2,000 lines per run. 2,000 lines took 3.8 s on the platform.
• Default-value method only. If you have verified actual emissions, use those instead.
• Simplified carbon-price deduction. Article 9 requires evidence and netting of rebates.
• Codes must use the 2026 CN. For example, 7601 10 00 became 7601 10 10 / 90. Older codes get a note.
• Why is my country "Other countries and territories"? Annex I has its own table for only about 121 countries. For the rest, the regulation uses the "Other countries and territories" values.
