In more than 30 years of service to its members, NACD has placed the highest priority on the health, safety, and security of employees, communities, and the environment. In December 1991, the member companies of NACD undertook the most important mission ever contemplated in the history of the Association, the creation of and required compliance with the Responsible Distribution process. This initiative was developed by NACD members for NACD members. Responsible Distribution is separate and not a part of any other chemical industry code of management practice. It has taken guidance from various codes but has always remained independent and specific to the domestic and global needs of the chemical distributor.
