AdBlue®

Your AdBlue solution

What is AdBlue®?

AdBlue is a diesel exhaust fluid used in vehicles with Selective Catalytic Reduction (SCR) technology to reduce harmful gases being released into the atmosphere. AdBlue is a 32,5 % solution of high-purity, synthetically manufactured urea in de-mineralized water. It is a safe-to-use fluid.

Yara's AdBlue product is certified according to ISO 22241 (ISO 22241-1, ISO 22241-2, ISO 22241-3). This international standard protects your vehicle from contamination which could cause serious damage. Using a urea solution of incorrect or low quality that does not follow these standards risks costly repairs.

If you are in Brazil, this product is called ARLA32.

If you are in the US, this product is called DEF (diesel exhaust fluid).

Since 2005, Yara has been a pioneer in this market. We have worked alongside and guided hundreds of retailers, distributors and fleets of all sizes in their choice of AdBlue and AdBlue equipment.

To find your nearest contact we have dedicated AdBlue Sales Teams in most countries.

How AdBlue works?

Vehicles with SCR technology have a separate tank filled with AdBlue. This is then injected into the exhaust pipe, in front of the SCR catalyst, downstream of the engine. 

Heated in the exhaust, it decomposes into ammonia and CO₂. When the NOx from the engine exhaust reacts inside the catalyst with the ammonia, the harmful NOx molecules in the exhaust are converted to harmless nitrogen and water, which are released from the tail pipe as steam.

Why buy AdBlue from Yara?

Yara is the market leader with a production capacity of 2,8 Mt of AdBlue a year – the largest in the world.

This AdBlue is sold around the world and comes from a solution of high-purity, virgin urea. 

Urea is produced synthetically from ammonia and CO₂ (carbon dioxide), from which Yara's AdBlue is extracted directly as "hot melt" urea, which uses a different process from fertilizer grade urea. 

This AdBlue process is quality assured to ensure an exceptionally pure result that meets the stringent specification set out in ISO 22241-1. This means you can rely on the quality and purity of Yara's AdBlue wherever you are.
