47 C.F.R. § 54.9 : Telecommunication — FEDERAL COMMUNICATIONS COMMISSION — COMMON CARRIER SERVICES — UNIVERSAL SERVICE — GENERAL INFORMATION — Prohibition on use of funds

(a) USF support restriction No universal service support may be used to purchase, obtain, maintain, improve, modify, or otherwise support any equipment or services produced or provided by any company posing a national security threat to the integrity of communications networks or the communications supply chain.
(b) Designation of Entities Subject to Prohibition.
(1) When the Public Safety and Homeland Security Bureau (PSHSB) determines, either sua sponte or in response to a petition from an outside party, that a company poses a national security threat to the integrity of communications networks or the communications supply chain, PSHSB shall issue a public notice advising that such designation has been proposed as well as the basis for such designation.
(2) Upon issuance of such notice, interested parties may file comments responding to the initial designation, including proffering an opposition to the initial designation. If the initial designation is unopposed, the entity shall be deemed to pose a national security threat 31 days after the issuance of the notice. If any party opposes the initial designation, the designation shall take effect only if PSHSB determines that the affected entity should nevertheless be designated as a national security threat to the integrity of communications networks or the communications supply chain. In either case, PSHSB shall issue a second public notice announcing its final designation and the effective date of its final designation. PSHSB shall make a final designation no later than 120 days after release of its initial determination notice. PSHSB may, however, extend such 120-day deadline for good cause.
(3) PSHSB will act to reverse its designation upon a finding that an entity is no longer a threat to the integrity of communications networks or the communications supply chain. A designated company, or any other interested party, may submit a petition asking PSHSB to remove a designation. PSHSB shall seek the input of Executive Branch agencies and the public upon receipt of such a petition. If the record shows that a designated company is no longer a national security threat, PSHSB shall promptly issue an order reversing its designation of that company. PSHSB may dismiss repetitive or frivolous petitions for reversal of a designation without notice and comment. If PSHSB reverses its designation, PSHSB shall issue an order announcing its decision along with the basis for its decision.
(4) PSHSB shall have discretion to revise this process or follow a different process if appropriate to the circumstances, consistent with providing affected parties an opportunity to respond and with any need to act expeditiously in individual cases.
