Inmetro certification

Inmetro is short for Instituto Nacional de Metrologia, Normalização e Qualidade Industrial, which is the National Institute of Metrology, Standardization and Industrial Quality. This institute is accredited by the Ministry of Development, Industry and Trade and cooperates with the Executive Secretariat of the National Council of Metrology, Standardization and Industrial Quality, also known as Conmetro.

Which products require a certificate

There are two different types of Inmetro certification:

  • Voluntary Certifications
  • Compulsory Certifications

Voluntary Certifications are granted to companies that decide by themselves that they want to have their goods or services certified by Inmetro. The decision to voluntarily apply for an Inmetro certification is usually made by Brazilian exporters to comply with international requirements. For example, the United States and the European Union demand that, for most products, a certificate stating that the product or service meets the requirements imposed by Inmetro. The complete list of products that can be voluntarily certified by Inmetro is:

  • Bottled natural mineral water
  • Computer goods
  • Ceramic blocks for masonry
  • Cachaça
  • Sisal fibre
  • Switches and circuit breakers
  • Low voltage electrical installations
  • Facilities and Equipment in the production of “Cestas Básicas
  • Materials and Equipment for civil construction
  • Plywood panels for structural and non-structural use
  • Dry salted pirarucu (Arapaima Gigas)
  • Ceramic plates for flooring
  • Ceramic tiles
  • Industrial valves for facilities exploring, producing and transporting petroleum products
  • Flat tempered glass


Having a product certified by an INMETRO accredited Certification Body provides assurance that the product complies with Brazilian rules and required safety standards. If you are planning to export goods to the Brazilian market which require certification, it is necessary that they are tested and approved by an accredited body. SERCONS has specialists employees, which will assist our clients in this process. Failure to do so could lead to products being banned, and may be subject to a fine.
