Colonial Chemical Company has been awarded the first license by the American Petroleum Institute (API) under the API Diesel Exhaust Fluid Certification Program. The API license certifies that materials used and fluid produced and marketed by Colonial Chemical meets international standards for automotive-grade urea. Many diesel engine manufacturers plan to recommend API-certified DEF for their 2009 light-duty diesel trucks and 2010 medium- and heavy-duty trucks.

DEF is a ultra-high-purity urea solution used in a system called Selective Catalytic Reduction (SCR) to remove acid rain-forming pollutants from diesel vehicle exhaust. The high purity of the DEF is critical to the performance of the SCR system. The API is launching a certification program to verify that its licensees are supplying DEF that meets internationally accepted standards. Use of API-certified DEF will assure that one is using and producing the correct quality of product.

Colonial Chemical has been producing urea solutions for stationary SCR systems for more than 10 years. It has been producing DEF since 2006, and today supplies it nationwide in bulk and packaged forms.
