[X] Rule 13p-1 under the Securities Exchange Act (17 CFR 240.13p-1) for the reporting period from January 1 to December 31, 2020.






SECTION 1 – Conflict Mineral Disclosure


Item 1.01 Conflict Mineral Disclosure and Report




Wireless Telecom Group, Inc., a New Jersey corporation, together with its subsidiaries (“we”, “us”, “our” or the “Company”), specializes in the design and manufacture of advanced radio frequency (“RF”) and microwave devices which enable the development, testing and deployment of wireless technology. The Company provides unique, highly customized and configured solutions which drive innovation across a wide range of traditional and emerging wireless technologies.


Our products include components, modules, instruments, systems and software used across the lifecycle of wireless connectivity and communication development, deployment and testing. Our customers use these products in relation to commercial infrastructure development, the expansion and upgrade of distributed antenna systems, deployment of small cell technology, use of medical devices and private long-term evolution (“LTE”) and 5G networks. In addition, the Company’s products are used in the development and testing of satellite communication systems, radar systems, semiconductor devices, automotive electronics and avionics.


The purpose of this Form SD is to provide information pursuant to Rule 13p-1 (the “Rule”) promulgated under the Securities Exchange Act of 1934, as amended (the “Act”). The Rule relates to the disclosure of certain information relating to “conflict minerals,” which are defined in the rule as gold, columbite-tantalite (coltan), cassiterite and wolframite, and their derivatives of tantalum, tin and tungsten (referred to in this Form SD as “3TG”).


The products we manufacture contain multiple parts and materials from a wide array of direct and indirect suppliers from around the world. There are typically multiple tiers of suppliers between the origin of the 3TG (mines and smelters) and our direct suppliers. Because we are a downstream purchaser of raw materials and components, we must rely on our direct suppliers to work with their upstream suppliers to obtain information about the origin of the 3TG contained in the products we manufacture or contract to manufacture. WTT manufacturing processes consist primarily of using manufactured components and assemblies from our direct suppliers and integrating them into system level solutions, instruments and components.




We conducted an analysis of the products and components we assembled during the 2020 calendar year and concluded that certain 3TG was necessary to the manufacture or functionality of those products and components. Accordingly, we conducted a reasonable country of origin inquiry (“RCOI”) to determine if any of the 3TG originated from the Democratic Republic of the Congo (DRC) or any adjoining countries (those and the DRC collectively referred to as “Covered Countries”) or if the 3TG was from recycled or scrap sources.


WTT’s RCOI process included conducting an inquiry using the RBA-GeSI Conflict Minerals Reporting Template (the “Template”) developed by the Responsible Minerals Initiative (“RMI”). We provided the Template to all of our direct suppliers and asked that they complete the template and return it to us for analysis. We conducted follow up with suppliers where information was missing or responses were absent.




Based on our RCOI, we concluded that we did not have sufficient reason to believe that all 3TG materials in our supply chain did not originate in a Covered Country or were from recycled or scrap sources. Accordingly, the Company further pursued its supply chain inquiry and conducted due diligence on that supply chain as required by the Rule. There was significant overlap between our reasonable country of origin inquiry efforts and our due diligence efforts.


Consistent with the statement of the staff of the Securities and Exchange Commission made public on April 7, 2017, WTT is not filing a conflict minerals report with this Form SD.


This Form SD is publicly available on our website at http://www.wirelesstelecomgroup.com/investor-relations under the heading “Conflict Minerals Disclosure”.
