Conflict Minerals Policy

Dear Customer,

Pursuant to Section 1502 of the Dodd-Frank Wall Street Reform Act, certain suppliers are required to make disclosure or certifications to their respective customers, regarding whether “conflict minerals” necessary to the functionality or production of their products originated in the Democratic Republic of Congo (“DRC”) or adjoining countries. These “conflict minerals” initially consist of specified minerals, and derivatives thereof namely Tantalum, Tin, Tungsten and Gold.

Certain products that CECO Environmental supplies are known to contain these minerals. We have informed our suppliers of these products, and that our policy is to purchase materials that are DRC “conflict free”. CECO Environmental has queried our suppliers and to the best of our knowledge, as of the date hereof, a majority of the conflict minerals used to produce our products have come from scrap or non-DRC mines. A few of our suppliers, however, responded that their source is undeterminable.

CECO Environmental is not responsible for third-party items that are specified by customers to be DRC “conflict free”. These items may include, but are not limited to, actuators, motors, fans, etc. CECO Environmental only has the ability to control the materials used in the fabrication of its own products.
