49 CFR 586.9 – Deemed approved registrations
(a) If NHTSA does not act on a registration within 90 days of NHTSA’s receipt of the submission, NHTSA will notify a registrant by email on or after the 90th day that the registration has been deemed approved. Registrants that have been deemed approved will be included on NHTSA’s list of approved replica motor vehicle manufacturers.
(b) A manufacturer that has not received an email notification from NHTSA about NHTSA’s decision on the application following 90 days from submission of the registration should contact NHTSA’s Manufacturers Helpdesk to determine the status of its registration (Email: manufacturerinfo@dot.gov; Telephone: 1-888-399-3277). Manufacturers may also contact the helpdesk for information about the status of their registrations at any time, or may themselves check the status using the key provided them when they submitted their registration application. A manufacturer that has not received an email confirmation from NHTSA that its registration has been deemed approved may be subject to enforcement action by NHTSA for violating 49 U.S.C. § 30112(a) if NHTSA finds that the registration was incomplete or denied, and that an email notification had been sent to the email address provided in the manufacturer’s submission.
(c) If NHTSA determines that a registration that had been deemed approved is incomplete or fails to meet the requirements for registrants in this part 586, NHTSA may request additional information from the registrant in writing, which includes by email. A manufacturer shall have 60 days to respond to a request for additional information. If the manufacturer fails to respond within the 60 days or submits information that does not support that it meets the requirements of this part 586, NHTSA may revoke the registration.
