Free here, for good: every number above - the 50 t verdict, the 2.5% factor, the certificates, the cost - with no key and no run limit. $60 once adds what the calculation cannot hand you: CSV export of every line you ran, and browser alarms for 1 Feb 2027 (certificate sales open) and 30 Sep 2027 (2026 declaration due). One licence key per person or team seat · 7-day full refund.

50 t/year de minimis check Tells you whether a calendar-year net mass is under the 50 t threshold of Art. 2(3a) (Reg. (EU) 2025/2083) and how many tonnes of headroom are left - and that hydrogen and electricity have no de minimis at all.
2026 certificate cost at the 2.5% factor Prices the certificates actually due: embedded CO2e x the CBAM factor (2.5% in 2026, 5% in 2027) x your EUA price, minus any carbon price already paid in the country of origin.
Art. 26 exposure line Shows the minimum penalty exposure on the same import at EUR 300 per tonne CO2e - the low end of the 3-5x rate for importing CBAM goods without authorised declarant status.
The two dates that replaced the quarterly report Returns the live deadline for your case: certificate sales open 1 Feb 2027 and the 2026 CBAM declaration is due 30 Sep 2027, or the Art. 26 warning if you are over 50 t and not authorised.
CSV export of every line you ran (paid) Writes goods group, net mass, factor, certificates due and cost to a .csv you keep, so the working behind your CBAM declaration leaves the browser with you.
Chrome alarms for 1 Feb 2027 and 30 Sep 2027 (paid) Sets the two CBAM dates as browser alarms so the declaration window does not pass while the calculation sits in a closed tab.

This page is the working piece. The full pack has everything below.
The 50 t de minimis, the 2.5% 2026 factor and the Art. 26 exposure, for one import line, in your browser
One CBAM certificate costs one EUA: EUR 82.48 per tonne CO2e (ICE EUA Dec-2026 benchmark, week ending 29 Aug 2026). The published price of getting it wrong is higher: EUR 100 per tonne CO2e for certificates not surrendered, and EU
It runs one import line through the 2026 CBAM rules. You give it the goods group, the net mass imported this calendar year, the embedded emissions per tonne and your EUA price. It returns whether you are over the 50 t de minimis, the chargeable CO2e after the 2026 factor of 2.5%, the certificates due, the cost, and the next deadline.
Who is it for?
EU importers and customs brokers moving iron and steel, aluminium, cement, fertilisers, hydrogen or electricity into free circulation. It is built for the person who has to answer whether a shipment crosses the 50 t line this year, and what the certificates for it will cost when sales open on 1 February 2027.
Why will a chatbot not do this?
Most models still answer with the transitional rules that ended in December 2025: a 150 EUR per consignment threshold, quarterly reports and certificate sales from 1 January 2026. The November 2025 Omnibus amendment replaced all three. This extension is built on the 6 numbers that took their place: 50 t a year, a factor of 2.5%, 1 Feb 2027, 30 Sep 2027, 31 Mar 2026, and 300-500 EUR per tonne.
What is free and what needs the key?
Every calculation is free forever, with no watermark, no run limit and no key: all 8 outputs, in the popup and on the web page. The 60 dollar key adds CSV export of the lines you ran and browser alarms for 1 February 2027 and 30 September 2027. It never blocks an answer.
What would this cost if a person did it?
No CBAM consultancy publishes a day rate, so the honest comparison is the published penalty. Certificates not surrendered cost 100 EUR per tonne CO2e, and CBAM goods imported without authorised declarant status cost 300 to 500 EUR per tonne CO2e under Article 26. One certificate itself is 82.48 EUR.
