INMETRO Electrical Safety Testing and Certification for Household Appliances

Achieving market access with INMETRO-accredited testing and certification services

As one of largest economies in the world, Brazil is a primary target market for companies seeking to expand their base of business with consumers in the global marketplace. Brazil’s National Institute of Metrology, Standardization and Industrial Quality, commonly known as INMETRO, administers mandatory scheme for the testing and certification of most products, including electrical household appliances and products, to help ensure the safety of consumers.

Only electrical household appliances that have been tested and certified by an INMETRO-accredited certification body are legally permitted to be sold in Brazil. Failure to obtain INMETRO certification can result in delays to market entry, or the required withdrawal or seizure of non-certified household appliances, and may also lead to financial penalties.

INMETRO’s technical requirements are based on the international standard IEC 60335 for household and similar electrical appliances, and product certification requires testing by an INMETRO-accredited certification body.

In addition to product testing, compliance with INMETRO certification includes a number of special challenges, such as the appointment of legal representative based in Brazil, annual factory inspections, and the translation of user documents into Portuguese.

TÜV SÜD Brazil is accredited by INMETRO as a Certification Body for a variety of electrical and electronic products, including electrical appliances and products. We can conduct electrical safety testing in our fully accredited laboratory partners in Brazil and TÜV SÜD laboratories elsewhere around the world, and our testing engineers are experienced in testing the complete range of electrical household appliances. Our electrical safety testing is also covered by our internationally accepted ILAC and IECEE CB Scheme accreditation, based on our compliance with ISO 17025.
