ISO 22241 Compliance at Every Stage
Quality is not an afterthought in DEF manufacturing — it is the entire point. Engines and SCR systems are sensitive to contamination, which means every step of our process is designed to prevent it. From the purity of our raw water supply to the cleanliness of our filling equipment, we maintain the controls that keep your product in spec and your customers' equipment running. Every batch is tested, documented, and traceable back to the raw materials that went into it.

We procure high-purity urea and deionized water from vetted suppliers, ensuring every input meets ISO 22241 raw material specifications.
Purification & Mixing
Urea is dissolved in deionized water at precisely controlled temperatures and ratios to achieve the 32.5% concentration required by the standard.
Quality Testing
Each batch undergoes laboratory analysis for urea concentration, alkalinity, biuret content, and trace metals before it moves to the filling line.
Filling
Automated filling lines handle everything from 1-gallon bottles to 330-gallon IBC totes with volumetric accuracy and contamination prevention protocols.
Labeling & Packaging
Products are labeled with your branding or ours, serialized for traceability, and palletized for efficient warehousing and transport.
Distribution
Finished DEF ships from our Pasadena, Texas facility via LTL, full truckload, or bulk tanker to destinations across the U.S. and internationally.
FAQ
Frequently Asked Questions
What is diesel exhaust fluid (DEF)?
DEF is a high-purity solution of 32.5% urea and 67.5% deionized water. It is injected into the exhaust stream of diesel engines equipped with Selective Catalytic Reduction (SCR) systems to convert harmful nitrogen oxides into harmless nitrogen and water vapor. DEF is required by EPA emissions regulations for most modern diesel vehicles and equipment.
Is your DEF ISO 22241 certified?
Yes. All DEF manufactured at our Pasadena facility complies with ISO 22241, the international standard that governs DEF purity, concentration, and contaminant limits. We test every batch in our on-site laboratory and provide certificates of analysis with each shipment.
What packaging formats are available for DEF?
We offer DEF in 1-gallon bottles, 2.5-gallon jugs, 55-gallon drums, 275-gallon totes, 330-gallon totes, and bulk tanker loads. We can also configure custom retail case packs and pallet configurations to match your distribution requirements.
Do you offer private label DEF programs?
Absolutely. Our private label program covers everything from product manufacturing to label design support, filling, and fulfillment. You provide your brand identity and sales channels, and we handle production and quality assurance. Many of our partners sell DEF under their own brand without operating a single piece of manufacturing equipment.
What are your minimum order quantities for DEF?
Minimum order quantities depend on the packaging format and whether you are ordering under our brand or a private label program. We work with businesses of all sizes, from regional distributors to national retailers. Contact our sales team for specific MOQ details for your situation.
What is the shelf life of DEF?
When stored properly between 12 and 86 degrees Fahrenheit and out of direct sunlight, DEF has a shelf life of approximately 12 months. Higher storage temperatures can reduce shelf life. We date-code every container so you and your customers always know the production date.
