Product Introduction:
1.What Is Diesel Exhaust Fluid (DEF)?
Diesel Exhaust Fluid, abbreviated as DEF, is a specialized liquid essential for modern diesel engines. It is composed of 32.5% high-purity urea and 67.5% deionized water, making it a precise blend tailored for a specific purpose. DEF serves as a crucial agent in reducing nitrogen oxide (NOx) emissions from diesel engines, which is significant for environmental protection.
2.How Diesel Exhaust Fluid Works?
When DEF is injected into the exhaust system of diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology, it undergoes a chemical reaction within the SCR catalyst. This reaction converts harmful NOx emissions into nitrogen and water vapor—two substances that are harmless to the environment. Specifically, DEF helps lower NOx emissions by up to a significant percentage, depending on the engine and SCR system's efficiency.
Automotive Grade Urea (AGU)
Automotive Grade Urea (AGU) is the key raw material in producing Diesel Exhaust Fluid (DEF). It's mixed with deionized water in a precise 32.5% urea to 67.5% water ratio, undergoing rigorous purification to ensure high purity and effectiveness in reducing NOx emissions. Unlike agricultural urea granules, which have lower purity standards suitable for crops, AGU meets stringent automotive industry specifications to ensure consistent performance in SCR systems. This precision and quality control make DEF a crucial fluid for modern diesel engines, contributing to cleaner air.

FAQ
Q1: What is your minimum order quantity?
A: 1*20' container (20mt)
Q2: What is the available packaging?
A: 50kg/bag and 1000kg/bag
OEM packaging (for quantity over 500mt)
Q3: How long is the delivery time?
A: The production time takes about 3 days when the quantity is less than 500mt. The specific delivery time is affected by the customs inspection policy.
Q4: Do you have a third-party certificate?
A: Yes, our products have been tested and approved by SGS, INTERTEK.
Q5: Can I test my goods at the loading port?
A: Yes, we can arrange SGS at the loading port, and the cost is paid by the customer separately.
Q6: Do you need pallets when loading?
A: Choose whether to use pallets according to your needs. For the convenience of unloading, we recommend that urea be loaded on pallets on the bottom layer when it is loaded in a 20' container, and only on the top layer if a 40' container is used.
Q7: Can you arrange a certificate of origin (such as FORM A/FORM F) for our import customs clearance?
A: Of course, we will do it for you.
Q8: Can I get free samples?
A: Free samples within 1 kg can be provided, and the courier fee is borne by the customer.
