What it means for your EU buyer

When an EU importer brings in this product from Türkiye without verified emissions data from the producer, it must use the EU default value above, plus a mark-up of 10% in 2026, 20% in 2027 and 30% from 2028. The free allocation deducted from the importer's obligation shrinks every year and ends in 2034, so the cost per tonne rises each year even though the default stays the same.

Several EU benchmarks fall under this code; the lowest was used, so costs may be overstated. Use the full 8-digit code in the calculator for an exact figure.

How to report a lower figure

For iron, steel and aluminium goods only direct emissions count: the fuels burned in your plant and the embedded emissions of the steel or aluminium you buy in. Electricity is not counted. Many producers, especially processors that buy in their steel or aluminium, come in well below the default. Your actual figure can replace the default once an EU-accredited verifier has checked it.
