INMETRO (National Institute of Metrology, Standardization and Industrial Quality) is Brazil's leading accreditation and certification authority. It oversees the implementation and regulation of product certification systems, accredits Certification Bodies (CBs), and defines technical regulations and certification requirements for various product categories. The INMETRO certification system covers both safety and energy efficiency aspects, comprising both mandatory and voluntary schemes, forming a crucial technical barrier for market access in Brazil.

Key INMETRO Certification Information:

1.Technical Standards:Products generally need to comply with Brazilian standards; typical mains voltage is AC 127V-220V, 60Hz; plugs must conform to ABNT NBR NM 60884-1:2004.

2.Certification Nature: Both mandatory and voluntary certification schemes exist.

3.Certificate Validity:Varies by product category – 2, 3, or 5 years (household appliances are often 3 years).

4.Factory Audit: Requires initial and subsequent annual surveillance audits (applicable to both the manufacturer and the Brazilian importer).

5.Certificate Holder: Applications must be submitted through a locally appointed Brazilian agent.

  INMETRO Certification Product Scope:

1.Mandatory Certification Products:

·Steel and cast iron pipes

·Steel ropes, wires, and cables

·Automotive parts (tires, wheels, batteries, shock absorbers)

·Medical electronic equipment

·Circuit protection devices

·Explosion-proof electrical equipment

·Gas system components

·Plugs, sockets, and switches

·Household appliances and IT equipment

2.Voluntary Certification Products:

·Industrial valves

·Building materials

3.Energy Efficiency Labeling Programs:

·Three-phase electric motors

·Photovoltaic modules

  INMETRO Certification Process:

1.Application Submission: Submit the certification application to a recognized laboratory or Certification Body.

2.Sample Preparation: Prepare test samples (commonly 3 units) and relevant technical documentation.

3.Product Testing: The laboratory performs testing according to the applicable standards and issues a test report.

4.Factory Audit: An audit is conducted at the manufacturing plant by accredited Brazilian auditors (often a team of two).

5.Report Evaluation: The audit report and test report are submitted to the Certification Body for comprehensive evaluation.

6.Certificate Issuance: Upon successful evaluation, the INMETRO certificate is issued.

According to Brazilian regulations, certified products are subject to periodic surveillance:

·Surveillance intervals vary by product category (e.g., 6/9/12 months).

·Includes importer checks, sample testing, and factory re-audits.

·May involve laboratory assessments and witness testing.

·Certificate renewal is contingent upon successful completion of surveillance activities.

  INMETRO Certification Required Documents:

1.Completed product test application form.

2.User manual and installation instructions in Portuguese.

3.Circuit diagrams and technical specifications.

4.List of critical components and their suppliers.

5.Detailed technical parameter documentation for all components.

  INMETRO Certification Timeline & Cost Analysis:

1.Certification Timeline:

·Standard products: Approximately 4 months or more.

·Complex products (e.g., automotive tires): Can extend up to 12 months.

 ·Non-mandatory products: Typically around 2 months.

2.Certification Costs:

·Basic product certification total cost is approximately USD 11,000 - 12,500 (approx. 80,000 - 90,000 RMB).

·Special categories (e.g., automotive tires) can exceed USD 28,000 (approx. 200,000 RMB).

The INMETRO certification system reflects Brazil's high standards for product quality and safety. Companies need to plan their certification strategy according to product characteristics to ensure successful market entry.
