3) E-mark test report and certificate
4) The specific information of the Brazilian agent, the address and the contact mode
4. Procedures
Present application--dispose the original papers--submit application--reviewed by the body--plan the factory audit--accompany for the factory audit and sample test--check the agent--issue the certificate
5. Certification period
Almost 80 working days in terms of the complete package of papers and the smooth pass of test. Sometimes, the factors of the factory audit and other unexpected things also should be taken into account.
6. Costs
Application fee/test fee/ travelling expense for the Brazilian officials/the factory audit and certification service costs
7. Certificate validity
In general, 4 years.
8. Factory audit
1) Brazilian official will come for reviewing the factory as which is required to pass the quality system audit. After issuing the certificate, the factory audit should be carried out every year while the dealer inspection for two years.
2) The audit is carried out on spot.
9. E-mark certification availability
In case of the tire having E-MARK certification, the related test reports and certificate can be directly used to apply for INMETRO while the factory audit is still required. (Note: as for the bicycle within the scope of Brazilian mandatory certification, it is only tested as per the Brazilian standards since the UN haven’t put it into the compulsory area.)
10. Extension of the INMETRO
According to the standards definition, the tire pattern is as a part of the tire specification. Thus the new tire pattern should be in the extended types of the certificate.

13. Rules for sampling test
After the division of the tire families, 1 specification out of the every family and 3 tires out of every specification are needed for the test.
14. Annual inspection for the certification
The annual audit needs the coordination among the technology, science research and development centers of the factory, the quality management control center and the lab. The inspectors will pay more attention to the aspect that whether the quality management system and production control are strict and other factors. The sampling test for tyres of several specifications is also on the plan.
