Class C and D devices not listed in Circular 30 can continue to be freely imported through December 31, 2024 with only a classification document. This being said, manufacturers of these products are encouraged to obtain a MA License at their earliest convenience. A full list of products requiring an MA license can be found in Circular 30/2015 and include ventilators, infant incubators, pacemakers, x-ray machines, MRIs, hemodialysis devices, etc.
It is possible that this deadline may be extended as the MOH continues to struggle clearing the backlog of MA applications for risk class C and D products.
