Class I · II · III · IV — Overview
Class I — Low risk | Pathway: Notificação
Largely administrative process — no detailed pre-market ANVISA technical review before market placement. Examples: Tongue depressors, non-sterile gauze, examination gloves, cold/hot packs.
Class II — Medium-low risk | Pathway: Cadastro
Abbreviated technical documentation + ANVISA simplified review (3–6 months). Examples: Single-use syringes, sterile examination gloves, manual wheelchairs, manual blood pressure monitors.
Class III — Medium-high risk | Pathway: Registro
Full technical dossier + ANVISA technical review (12–24 months). Examples: Digital X-ray systems, powered wheelchairs, anaesthesia machines, haemodialysis equipment, CT scanners.
Class IV — High risk | Pathway: Registro (highest scrutiny)
Most stringent pathway — substantial clinical evidence and thorough ANVISA review (18–36 months). Examples: Pacemakers, implantable defibrillators, heart valves, drug-eluting stents, cochlear implants.
All registrations are valid for 10 years.
