Conflict Minerals Policy

Contour Metrological & Mfg., Inc. (CMM) complies with Customer requests to report conflict minerals usage.  CMM policy also requires suppliers to disclose the use of conflict minerals in their products or products that they contract to manufacture where they are “necessary to the functionality or production” of those products.

This policy is in response to violence and human rights violations in the mining of certain minerals from the “Conflict Region”, which is situated in the eastern portion of the Democratic Republic of the Congo (DRC) and surrounding countries.  The definition of “conflict minerals” refers to gold, as well as tin, tantalum, and tungsten, the derivatives of cassiterite, columbite-tantalite, and wolframite, regardless of where they are sourced, processed or sold.  The U.S. Secretary of State may designate other minerals in the future. 

We support the humanitarian goal of ending violent conflict in the DRC and surrounding countries.  We are committed to the responsible sourcing of “conflict minerals” throughout our supply chain.
