To understand the Brazilian INMETRO certification process and timeline, it’s first important to recognize that there is no fixed "standard duration". The entire certification is more like an "open-book exam" assessing an enterprise’s comprehensive capabilities, with a core logic: proving your ability to consistently and stably produce safe products identical to the tested samples.

Thus, the timeline ranges from several months to over a year—speed depends entirely on the enterprise’s preparation level and product complexity.

Brazilian INMETRO Certification Process

Phase 1: Preparations & Project Planning (Approx. 1-2 Months—Determines Overall Efficiency)

This is the most critical yet often overlooked phase, directly determining whether pitfalls will be encountered later.

1.Confirm Certification Scheme & Local Representative: First, identify the specific certification scheme applicable to your product (e.g., the common Scheme 5 for high-risk products). Simultaneously, overseas manufacturers must appoint a legally registered local company in Brazil as their legal representative—a mandatory legal requirement.

2.In-Depth Standard Interpretation & Document Preparation: Collaborate with the certification body and laboratory to confirm all applicable Brazilian standards, and begin preparing a complete set of Portuguese technical documents, including product descriptions, circuit diagrams, and Critical Component List (CDF). Notably, starting in 2025, standards for certain product categories (e.g., specific home appliances) have been updated—ensure the latest versions are used.

3.Sample Preparation: Prepare samples in final mass-production status, including packaging and labels. Any discrepancies from the products to be sold in the future may lead to subsequent issues.

Phase 2: Sample Testing & Report Issuance (Approx. 2-4 Months)

This is the core technical phase with a relatively fixed timeline.

Samples must be sent to a Brazilian officially accredited laboratory for testing. The testing cycle depends on product complexity and laboratory queue times. If tests pass on the first attempt, the process typically takes 2 to 4 months. However, if tests fail and modifications are required, the timeline will be significantly extended. A key trend: For products requiring energy efficiency certification (PBE) (e.g., lighting fixtures, home appliances), energy efficiency testing is often conducted in parallel with safety testing and requires a separate application to INMETRO.

Phase 3: Factory Audit (Initial Audit—Approx. 1-2 Weeks On-Site + Report Time)

For most mandatory certified products (e.g., home appliances, lighting fixtures, toys), the initial factory audit is mandatory and cannot be skipped.

Auditors will conduct on-site evaluations of the enterprise’s quality management system, focusing on verifying the factory’s ability to ensure production consistency. Key areas of inspection include:

·Production lines and critical process control points.

·Calibration records and traceability of testing equipment.

·Supplier management and incoming inspection records.

·Internal testing capabilities and non-conforming product control processes.

Depending on the enterprise’s scale, on-site audits typically last several days to a week, followed by the auditor issuing a report. Success depends on the actual level of daily quality management, not temporary preparations.

Phase 4: Review, Certification & Post-Certification Maintenance (Approx. 1-2 Months)

After compiling all test reports and factory audit reports, they are submitted to the INMETRO-accredited certification body for final technical review. Once approved, the INMETRO certificate is issued, and the process enters its final stage.

However, this is not the end. Certificates are typically valid for 5 years. During this period, the certification body conducts unannounced annual surveillance audits (market sampling + factory inspections) to ensure ongoing compliance. Any changes affecting product safety or performance must be reported to the OCP for approval in advance.

Planning an INMETRO certification project requires reserving a complete time window of at least 6 to 10 months. The key to success is integrating certification requirements into product development and production management as inherent components, rather than post-facto remedies.
