National Institute of Metrology, Quality and Technology (INMETRO) is a government agency that regulates and accredits certification processes in Brazil. Brazil adopted the INMETRO Decree 371 in 2011, which increased the certification standard for specific electrical and electronic household appliances to protect consumers and improve manufacturing. According to CONMETRO Resolution No. 4/02, the safety and EMC approval process must be carried out through INMETRO-accredited and approved product manufacturers
The certification organization defines the requirements for manufacturing inspections, laboratory testing, and documentation in accordance with Brazil ABNT standards. For wireless/telecom products ANATEL approval is required.
