Conflict Minerals are defined by the Securities and Exchange Commission (SEC) as cassiterite, columbite-tantalite, wolframite and gold, and their derivatives, which are limited to tin, tantalum and tungsten (collectively “3TG”).  As a result of the Company’s reasonable country of origin inquiry for the period January 1 to December 31, 2014 described in the attached Form SD, 3M has reason to believe that a portion of the 3TG necessary to the functionality or production of products (“Necessary 3TG”) that we manufactured or contracted to manufacture during the period between January 1, 2014 and December 31, 2014 may have originated in the Democratic Republic of Congo (DRC), the Republic of the Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola (together, the “Covered Countries”) and has reason to believe that those Necessary 3TG may not be from recycled or scrap sources.
