Item 1.01 Conflict Minerals Disclosure and Report
Conflict Minerals Disclosure
Powell Industries, Inc. (the Company) undertook a reasonable country of origin inquiry with respect to the conflict minerals used in the production of the Company’s custom engineered-to-order electrical equipment and has determined in good faith that for the year ended December 31, 2017.
For the year 2017, certain of our operations manufactured, or contracted to manufacture, products for which 3TGs, as defined below, are necessary to their functionality or production (“Covered Products”). Conflict minerals are defined in Section 13(p) as (A) cassiterite, columbite-tantalite (coltan), gold, wolframite, and their derivatives, which are limited to tin, tantalum and tungsten (together with gold collectively referred to as 3TGs), or (B) any other mineral or its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of Congo ("DRC") or any adjoining country that shares an internationally recognized border with the DRC. Accordingly, we have conducted a reasonable country of origin inquiry that was designed to determine whether any of the 3TGs in our Covered Products originated in the DRC or an adjoining country (Angola, Burundi, the Central African Republic, the Republic of the Congo, Rwanda, South Sudan, Tanzania, Uganda or Zambia), or were from recycled or scrap sources.
A copy of the Company’s Conflict Minerals Report is filed as Exhibit 1.01 hereto and is publicly available at the Company’s website at, under the section entitled “Investors.”
