DDL, Inc. is third-party testing laboratory specializing in package, product and materials testing for the medical device, pharmaceutical and consumer products industries.  DDL has been in the medical device package, product and material testing industry for over 20 years. We strive to offer the most effective business practices while employing a staff of technical experts.

DDL, a third party testing lab, was founded in 1990 by John Hart and Patrick Nolan. John and Pat had previously worked for Eden Prairie based testing products supplier MTS Systems. The two started DDL (Distribution Dynamic Labs) when an opportunity for a testing lab presented itself.

In January of 2003, DDL opened a second package and product testing lab in Costa Mesa, California.  That lab moved to Fountain Valley, California in 2009. Both facilities are registered with ISO 9001:2008 In September of 2007, DDL merged with TCP Reliable, a full service manufacturer for cold chain packaging products, located in Edison, NJ.  

In addition to medical device package testing DDL also performs product and materials testing with a specialty in medical devices.
