Class A route (pending draft)
Pending draft decree: devices classified as Class A would not require a Certificado de Registro Sanitario but must be inscribed with DNDM; the class A inscription certificate would be valid five years. IVDs grouped in four classes per GHTF/IMDRF rules, with class A IVDs likewise inscription-only.
- Draft under consultation — NOT in force; current treatment of class A under DE 490 unverified.
Ley 90 Art. 23 currently subjects class A to mandatory registration after the (expired) 42-month transition.
