AdBlue® and SCR: a business buyer’s guide

Understand what AdBlue / AUS 32 does in SCR exhaust treatment and the information business buyers should request before ordering.

The short answer

AdBlue® / AUS 32 is an aqueous urea solution used in suitable diesel SCR exhaust-treatment systems. It helps reduce nitrogen oxides in the exhaust. It is stored separately and is not mixed into diesel fuel.

What does SCR do?

SCR stands for selective catalytic reduction. In the exhaust-treatment system, the urea solution supports a reaction that reduces nitrogen oxides to nitrogen and water. Follow the vehicle or equipment manufacturer’s instructions for the correct fluid and filling procedure.

What should a business buyer check?

  • Identify the required product and specification.
  • Ask for the documents your purchasing process needs.
  • Choose a supply format that matches handling and demand.
