Automotive grade urea is the raw material to produce AdBlue (DEF / AUS 32), which is a kind of liquid for reducing nitrogen oxide pollution in diesel vehicle exhaust. Our product has advantages of low biuret and Aldehyde free, you can use it to produce high quality urea solution, final product can fully meet standard of ISO22241.
We supply automotive grade urea much cheaper than other traders. If you buy more than 500 tons, we will wholesale it to you at the lowest wholesale price!
Description of low biuret urea 99% high purity SCR UREA with SGS testing.
What is SCR?-—SCR (Selective Catalytic Reduction) transforms the harmful nitrogen oxides (NOx) in the exhaust of diesel vehicles into harmless nitrogen gas and water vapour. The SCR solution is metered into the exhaust system in front of a catalyst. The urea hydrolyses to ammonia which then reacts with the NOx in the exhaust gas.
What is DEF?—-DEF is aqueous urea solution used in SCR systems on diesel vehicles. SCR Urea complies with ISO 22241-1 and DIN 70070 standards why our SCR urea can be making DEF?—-The raw material of our urea is pure natural gas, so that the urea is with low Biuret, low Aldehydes and low heavy metal materials; We have the most advanced production equipment and testing equipment.

Packaging & Shipping
Packing Method:
For small samples quantity <1 kilograms, inside we use double resealable zip bags and outside with aluminium Foil Bags.
For small samples quantity <1 kilograms, inside we use double resealable zip bags and outside with aluminium Foil Bags.
For medium quantity, normally we pack them in pet bags (normally 25KG per bags).
For larger quantity, normally we pack them in jumbo bags (normally 1000KG per bags).
We do supply smaller packages like 10gram/50gram per bag as your requirement. Please contact us for more details if you have any questions!
