Passage 1

Our review also revealed statements that you manufacture these devices within the meaning of section 510 of the Act (21 U.S.C. § 360) (e.g., “We pay obsessive attention to every design aspect, leaving no detail overlooked so that our community can live and experience a life unbound.”). Under section 510 of the Act (21 U.S.C. § 360), manufacturers of medical devices are required to annually register with the FDA. In September 2007, section 510 of the Act was amended by the Food and Drug Administration Amendments Act of 2007 (Pub. L. 110-85) to require domestic and foreign device establishments to submit their annual establishment registration and device listing information to FDA by electronic means [section 510(p) of the Act (21 U.S.C. § 360(p))] during the period beginning October 1st and ending December 31st of each year. Our records indicate that you have not registered or listed these devices for fiscal year 2026.
