On 29 December 2009, INMETRO, the Brazilian quality, standards and metrology bureau, issued Ordinance 371 stipulating that any electrical household appliances made in or imported to Brazil need to pass mandatory product certification before being sold on the Brazilian market. The Ordinance’s implementation was divided into three stages spanning over 2011, 2012 and 2013. On August 8, 2011, INMETRO issued Ordinance 328 as an amendment to explain, clarify and supplement parts of Ordinance 371. Below is a detailed review of the two ordinances.

These Ordinances are a clear sign of a transition from voluntary to mandatory certification for Brazilian electrical appliances. With this new requirement to electrical appliances exported to Brazil, exporters should become acquainted with the specific requisites of mandatory technical certification in Brazil as soon as possible. Designs need to be updated and products need to be better prepared for export in this growing consumer market.

INMETRO’s effective Date on Electrical Household Appliances

Ordinance 371 is being implemented in three stages. In the first stage, starting with July 1, 2011, manufacturers or importers of electrical household appliances are forbidden to import products without mandatory certification.  The second stage, which starts on July 1, 2012, forbids manufacturers and importers to sell products to wholesalers and retailers without the mandatory certifications. In the third stage, starting January 1, 2013, wholesalers and retailers of electrical household appliances will be forbidden from selling products without the mandatory certifications.

The implementation date of these three stages has been postponed by one year for a series of products mentioned in Ordinance 328/2011, which supplements the product range stipulated in ordinance 371/2009. These products are: compressors, electrical stoves, electrical ovens (except those covered by IEC 60335-2-36 and IEC 60335- 2-42), commercial microwave ovens covered by IEC60335-2-90, jacuzzis, dryers, dishwashers, wine fridges, freezers, commercial refrigerators,  hybrid accumulation water heaters and heat pumps.

Products Covered by Ordinance 371

Ordinance 371 applies to most electrical household appliances included in ABNT, NBR, NM, NM National Standards or IEC 60335-2-X, except:

  • Products included in other clauses of INMETRO, e.g. water dispensers (Ordinance 191), gas furnaces (Ordinance 18), electric heat showers (Ordinance 211), refrigerator and freezers (Ordinance 20), air conditioners (Ordinance 14), washing machines (Ordinance 185), etc.
  • Products excluded in Ordinance 328: centrifuge covered by IEC 60335- 2-4, microwave ovens covered by IEC 60335-2-25, commercial electric ovens covered by IEC 60335-2- 36 and IEC 60335-2-42, water pumps covered by IEC 60335-2- 41, motor-driven pumps in IEC 60335-2-51(stationary circulation pumps for heating and service water installations), UV and IR radio skin exposing devices covered by IEC 60335-2-27, massagers covered by IEC 60335-2-32, projectors and similar equipment covered by IEC 60335-2-56.

Requirements of Ordinance 371

Testing requirements. Ordinance 371 only sets requirements for safety tests, without requirements for EMC or energy efficiency testing. According to the Ordinance, all products covered should be in compliance with IEC 60335-1 and IEC 60335-2-X, as well as any Brazilian national deviations. But, at present, only electric irons covered by IEC 60335-2-3 are required to  comply with the following deviation: Power cords of electric irons should be in compliance with Ordinance 286.

Meanwhile, electric plugs or sockets incorporated in household appliances exported to Brazil should acquire INMETRO NBR14136. Test Report Requirements. To apply for the INMETRO mandatory product certification, test reports issued by ILAC labs (International Laboratory Accreditation Cooperation) can be accepted. Furthermore, because Brazil is IECEE member, exporters can use their CB reports and certifications to acquire national certification in Brazil.

Importer Requirements. The Ordinance also stipulates that importers who apply for the mandatory INMETRO Mark shall establish a Customer Service Center to provide the relevant  support to Brazilian consumers. 

Exporter / Factory Requirements. Ordinance 371 stipulates that regular assessments of  manufacturers shall be conducted to ensure their compliance with the requirements.

As for domestic exporters of electric household appliances, because most requirements in Ordinance 371 are similar to those of CE and GS in the European Union, they can use the certification for export to Brazil if they update the product design and make timely preparations for certification.

INMETRO Mandatory Certification Mark

Products with mandatory certification, certified through a certification body officially recognized by Brazil, should be labelled with the INMETRO Mandatory Certification Mark.

As for the product mark, the first priority is the orange certification label, the length of which should be a minimum of 50mm (see image 1 below). The second option is a black and white label, the same length as the colour version (image 2). If the size of the product is too small and the first two kinds of labels cannot be attached, a third simplified label version can be used (image 3).

INMETRO Mandatory Certification Document

The rated voltages in Brazil are 127v and 220v, 60Hz. In many households, 127v and 220v are both available. Thus products exported to Brazil may have two versions of rated voltage in one model.

The INMETRO Certification is a one model one certificate type, and there are two definitions to “one model”:

  • Same model no. name with two different rated voltage versions (127V and 220V)
  • Two different model no. names, the only difference due to the voltage difference (127V and 220V).

Other INMETRO Mandatory Certificate restrictions include: the Certificate owner should be a Brazilian importer; one Certificate can only use one trademark, which has a validity of three years.

SGS support with INMETRO mandatory certification

SGS Brazil is accredited to directly issue INMETRO certifications and has already helped many customers to acquire the Brazilian INMETRO certification. The  SGS INMETRO code is: OCP 0040. 

SGS can provide you a complete one-stop service, covering tests, rectifications, factory inspections and document application for the INMETRO Mandatory Certification for electrical and electronic products.
