INMETRO (National Institute of Metrology, Standardization and Industrial Quality) is a government department directly under the Brazilian Ministry of Development and Foreign Trade.

INMETRO certification is a mandatory certification of the INMETRO logo under the supervision of national audit organizations in Brazil, mainly targeting specific product categories that wish to enter the Brazilian market, namely mandatory and voluntary categories. Electrical equipment used in flammable gas or explosive dust environments is a mandatory certification product.
