Conflict Minerals Disclosure
Parker-Hannifin Corporation (including its consolidated subsidiaries, the “Company”) is filing this Form SD pursuant to Rule 13p-1 under the Securities Exchange Act of 1934 for the reporting period from January 1, 2023 to December 31, 2023 (the “Reporting Period”).
Rule 13p-1, through Form SD, requires the disclosure of certain information if a company manufactures or contracts to manufacture products for which certain “conflict minerals” (as defined below) are necessary to the functionality or production of such products. Form SD defines “conflict minerals” as: (i)(a) columbite-tantalite (or coltan, the metal ore from which tantalum is extracted), (b) cassiterite (the metal ore from which tin is extracted), (c) gold and (d) wolframite (the metal ore from which tungsten is extracted), or their derivatives, which are currently limited to tantalum, tin and tungsten; or (ii) any other mineral or its derivatives determined by the U.S. Secretary of State to be financing conflict in the Democratic Republic of the Congo or an “adjoining country,” as such term is defined in Form SD (collectively, the “Covered Countries”).
The Company’s operations may at times manufacture, or contract to manufacture, products for which conflict minerals are necessary to the functionality or production of those products (collectively, the “products”). As required by Form SD, the Company has conducted a good faith reasonable country of origin inquiry (“RCOI”) regarding the conflict minerals included in its products during the Reporting Period, which the Company refers to as the “Subject Minerals,” to determine whether any such Subject Minerals originated in the Covered Countries and/or whether any of the Subject Minerals were from recycled or scrap sources. Where applicable, the Company has conducted additional due diligence regarding the sources of the Subject Minerals. The results of the Company’s RCOI regarding the Subject Minerals, as well as its additional due diligence regarding the sources of such Subject Minerals, are contained in the Company’s Conflict Minerals Report, a copy of which is filed as Exhibit 1.01 to this Form SD, and is publicly available at www.parker.com. The content on, or accessible through, any web site referred to in this Form SD is not incorporated by reference into this Form SD unless expressly noted.
Item 1.02    Exhibit.
As specified in Section 3 of Form SD, the Company is hereby filing its Conflict Minerals Report as Exhibit 1.01 to this Form SD.
Section 2    Resource Extraction Issuer Disclosure
