CBAM default values for CN 2834: Nitrates of potassium

These are the official EU default values (specific embedded emissions, tCO₂e per tonne of product) for every CN code under heading 2834, by country of origin — 90 countries, as published in Implementing Regulation (EU) 2025/2621 and corrected by Implementing Regulation (EU) 2026/1740 (retroactive to 1 January 2026). Importers use them whenever verified installation data is not available.

Sector: Fertilisers. Direct and indirect emissions both count; the default value is their total.
Mark-up on default values: 1% in 2026, 1% in 2027, 1% from 2028 — added to the values below when you declare on defaults.
Free allocation: for 2026 you surrender certificates for embedded emissions minus the CBAM benchmark × 97.5% (Art. 31, Reg (EU) 2023/956; Reg (EU) 2025/2620). The benchmark follows the production route shown in the table.

What 2026 costs on CN 28342100: worked examples

1,000 tonnes of CN 28342100 (Nitrate of potassium), on the official default value with the 1% mark-up, at the published certificate price of €82.32/tCO₂e. You surrender is the 2026 obligation after the free allocation adjustment; full exposure is the same shipment once free allocation has gone (2034).

Questions about CN 2834

What is the CBAM default value for CN 28342100 from China?

The official EU default value for CN 28342100 (Nitrate of potassium) from China is 2.85 tCO2e per tonne before the mark-up; with the 1.0% mark-up for 2026 it is 2.879 tCO2e per tonne. On 1,000 t that is about €186,714 of 2026 certificates to surrender at the published price (€82.32/t).

Which emissions count for CN 2834 under CBAM?

Direct and indirect emissions count for fertilisers goods: the default value is the total of both.

How much mark-up is added to the CBAM default values for CN 2834?

The default value carries a regulatory mark-up of 1% in 2026, 1% in 2027 and 1% from 2028 (Implementing Regulation (EU) 2025/2621). Verified actual emissions from the installation replace the default and carry no mark-up.

How do I use actual emissions instead of the default value for CN 2834?

Ask the producing installation for its specific embedded emissions, calculated under the EU method and checked by an accredited CBAM verifier. Until then the default value for the country of origin applies.

Replace the default with verified data

Default values are a conservative fallback, not a measurement of any plant. Verified actual emissions from your supplier's installation remove the mark-up and usually lower the bill. CBAM Compliance invites your suppliers in their language, computes their figure with the official method, and produces registry-ready QReport XML. See your full exposure or read how default values work.
