A Must-Read for Exporting to South America: A Comprehensive Guide to Brazil’s INMETRO Certification and Inspection Requirements

Brazil is South America's largest economy and a key market for Chinese productsSouth American Marketthe key gateway. However, to enter the Brazilian market, companies must first clear one of the most stringent product compliance hurdles in the Americas: INMETRO certification.

Many exporters run into trouble in Brazil not because their products are substandard, but because they get held up by certification and customs clearance compliance issues—such as labels lacking Portuguese text, missing INMETRO marks, plugs that don’t meet Brazilian standards, or certificate holders who aren’t local entities. All of these can result in goods being detained at the port of destination or even returned.

As a third partyinspection of goodsAt the pre-shipment inspection (PSI) site for shipments to Brazil, we repeatedly encounter the same types of issues. Below, we’ll explain the INMETRO process and ”how an inspection can help you” in one go.

I. What is INMETRO? Why is it essential for exports to Brazil?

INMETRO (Instituto Nacional de Metrologia, Qualidade e Tecnologia, the Brazilian National Institute of Metrology, Standardization, and Industrial Quality) is Brazil’s national authority for metrology and certification, responsible for developing national standards, conducting product conformity assessments, and regulating market access.

Simply put: Products listed in the mandatory certification directory may not be sold, imported, or stored in Brazil without INMETRO certification. This serves as Brazil’s version of a ”mandatory product market access gate” and operates in conjunction with customs and market regulation authorities (Procon)—products without valid certificates will be detained, removed from shelves, or even subject to penalties.

II. Scope of Products Subject to Mandatory Certification (2025–2026)

INMETRO certification is divided into two categories: **Compulsory and Voluntary**. Products listed in the compulsory catalog must be certified, while voluntary certification can enhance market competitiveness. Common areas covered by compulsory certification (examples):

Regulatory Updates for 2025–2026 (As of July 2026; exporters should pay special attention to the following):

Footwear Labeling (Decree No. 459/2025):Effective August 20, 2025, footwear labeling will transition from voluntary to mandatory, requiring compliance with ABNT NBR 16679:2018. Labels must include the manufacturer’s name/CNPJ, country of origin in Portuguese, size, main materials, and the GTIN code (which may be printed on the packaging or directly on the shoe). The compliance deadline for manufacturers and importers is July 31, 2026 (approximately two weeks remaining); retailers and e-commerce platforms may sell existing inventory until December 31, 2027. Violations are subject to a maximum fine of approximately 1.5 million reais (equivalent to approximately $280,000).

LED Lighting Fixtures and Light Sources (Decree No. 231/2026):Published and effective as of May 5, 2026; consolidates technical quality specifications, conformity assessment, and the ENCE energy efficiency label, replacing No. 69/2022; The scope has been expanded to include general-purpose and decorative LED luminaires, as well as RGB and smart lights, and specific exemptions have been clarified (e.g., Christmas decorative lights, streetlights, OLEDs, automotive and medical lighting, etc.). Manufacturers and importers have an 18-month transition period (until November 5, 2027), while retailers have a grace period until May 5, 2030; New requirements include power factor, flicker, harmonics, and CISPR 15:2018; the ENCE label must include a scannable QR code.

IT Equipment (Decree No. 211/2026):Released in April 2026, this update strengthens the conformity assessment for IT and data processing equipment—placing greater emphasis on accredited OCPs, enhancing product identification and traceability (serial numbers/product identifiers), and expanding technical documentation requirements. Existing certificates covered by the update are generally granted a transition period; upon expiration, they must undergo re-evaluation.

In addition, according to data compiled by certification industry organizations, commercial dispensing equipment, vending machines, and energy storage batteries have been included under new mandatory regulations; Decree No. 314/2025 updates the requirements for helmets, fire extinguishers, and automotive natural gas cylinders; and regulations for fans, air conditioners, and other products are currently under revision. The specific mandatory list and effective dates are subject to the latest Portaria (decree) officially published by INMETRO and the Brazilian Official Gazette (Diário Oficial).

III. Certification Process and Timeline (Led by OCP)

INMETRO certification is administered by **OCP (Organismo de Certificação de Produto, a product certification body accredited by INMETRO)**; companies (including Chinese exporters) typically proceed through Brazilian importers or agents. Typical process:

Confirm the certification type: Check the INMETRO official website directory or contact an authorized body to determine whether the product is subject to mandatory certification and which certification model applies (e.g., Model 5: testing + factory audit, applicable to high-risk products; Models 4/7: testing + batch audit, applicable to low-risk products or small batches).

Designation of a Local Representative in Brazil: The application must be submitted by a Brazilian importer or authorized agent acting as the legal entity, and the certificate must be held by that entity.

Prepare technical documentation: Business License (notarized in both Chinese and Portuguese), Product Technical Specifications, Circuit Diagrams, List of Key Components (CDF), Portuguese User Manual, Label Design featuring the INMETRO mark and OCP number, and ISO 9001 certification (if applicable).

Product Testing: Conducted at a Brazilian-accredited (RBC) laboratory or an ILAC-recognized laboratory. For products that already hold a CB Certificate, supplementary testing for Brazilian national differences (deviations between NBR and IEC standards, such as plug types, voltage, and tropical climate considerations) may be performed to facilitate the certification process; however, the CB report cannot directly substitute for a full local conformity assessment.

Factory Audit: Mandatory certification requires an initial factory audit (covering production consistency, incoming material inspection, equipment calibration, and the quality management system). During the certificate’s validity period, an annual surveillance audit and market spot checks are also required.

Certificate Issuance and Maintenance: Certificates are issued by the OCP and bear a unique identification number; the validity period is typically 2, 3, or 5 years (3–5 years for most home appliances; for toys, it may vary by batch). Failure to pass the annual surveillance audit will result in the suspension or revocation of the certificate.

Process Duration: Typically 3–6 months without corrective actions; approximately 8–10 weeks for simple products (such as plugs and sockets); up to 6–8 months or even 12 months for high-risk products (medical devices, automotive tires). Errors in document translation and retesting due to corrective actions will extend the process duration.

IV. Key Compliance Points to Monitor Closely Before Clearing Customs

Note: Food, pharmaceuticals, cosmetics, and other products are subject to separate regulatory agencies (such as ANVISA) and are not covered by INMETRO’s general product certification; please refer to the official directory for specific details.

V. How Third-Party Inspection Can Help You Mitigate Risks Before Shipping

INMETRO audits the ”certification and documentation system,” while a physical inspection verifies whether ”the actual products match the certification and documentation.” A physical inspection cannot replace OCP certification, but it can identify compliance issues at the factory before the goods ship, thereby preventing them from being detained upon arrival at the port.

5.1 Label and Marking Verification

Are the INMETRO mark and OCP number permanently and clearly marked on the product and packaging?;

Are the labels/instructions in Portuguese? Are the model number, voltage, manufacturer, and date of manufacture all listed?

5.2 Plugs and Electrical Adapters

Verify that the plugs on products with plugs comply with NBR 14136; ensure that the voltage markings cover 127V/220V 60Hz to prevent the inclusion of U.S.-standard plugs.

5.3 Conformity of the Physical Unit with the Certified Model

Verify that the model, specifications, materials, and key components (as listed in the CDF) of the shipped products match those of the certified samples. Unauthorized replacement of power modules, antennas, or circuitry, or adjustments to power settings or frequency bands, may trigger the need for recertification.

5.4 Quantity, Packaging, and Shipping

Count each box individually and check the markings and packaging to avoid short shipments, incorrect shipments, or mixed shipments—all of which can cause discrepancies between the customs declaration and the actual goods.

5.5 Documentation and Traceability

Verify that the test reports, certificates of origin, and Portuguese-language documents are complete and accurate to ensure that the importer’s documentation matches the goods during customs clearance and market supervision in Brazil.

VII. Common Mistakes in the Industry

The following are frequently asked questions at inspection sites. They do not refer to any specific customer and are provided for self-checking purposes:

Scenario A: Packaging is in English or Chinese only, with no Portuguese → Customs clearance and market regulation authorities raise concerns; labels must be added and the shipment reshipped, resulting in a missed shipping deadline.

Scenario B: The plugs use the U.S. NEMA standard → This is prohibited in Brazil, so the entire batch is non-compliant and must have the plugs replaced or be reworked.

Scenario C: The shipped model differs from the certified sample by one suffix, or a different power supply supplier was used → Production consistency does not match, resulting in delays during surveillance audits or customs clearance.

These aren’t ”quality issues,” but rather compliance details—yet they’re enough to cause an entire shipment to be held up at the port or pulled from the shelves.

VIII. FAQ

Q1: What is the relationship between INMETRO and OCP?

A: INMETRO is Brazil’s national accreditation authority, responsible for establishing regulations and overseeing compliance; OCP is a product certification body accredited by INMETRO that conducts testing, performs factory audits, and issues certificates.

Q2: Do all products require INMETRO certification?

A: No. Certification is required only for products listed in the INMETRO mandatory regulations (Portaria); for all others, voluntary certification may be obtained to enhance competitiveness.

Q3: How long is the certificate valid?

A: Depending on the product category, the typical validity periods are 2, 3, or 5 years (home appliances are usually 3–5 years, while toys may vary by batch); an annual surveillance audit must be passed within the validity period.

Q4: Can an existing CB certificate be directly converted to an INMETRO certificate?

A: It cannot be a complete substitute. Products that already have a CB certificate can undergo supplementary testing for Brazilian national differences (such as plug types, voltage, and tropical climate) through the certificate conversion process, but local conformity assessment must still be completed.

Q5: Can I apply without a Brazilian company?

A: You cannot hold the certificate directly. It must be submitted and held by a Brazilian importer or authorized agent acting as the legal entity.

Q6: What are the consequences of noncompliance?

A: Uncertified products will be detained by customs, forcibly removed from e-commerce platforms, and may be subject to heavy fines (industry data indicates the maximum fine can reach approximately $200,000).

Q7: Can a product inspection replace INMETRO certification?

A: No. Inspection is a physical compliance check conducted before shipment; it complements the OCP certification system and helps you catch basic compliance errors—such as inconsistencies in labels, plugs, and model numbers—before shipment.

Q8: What new changes are in store for 2025–2026 (as of July 2026)?

A: ① The mandatory labeling regulation for footwear (No. 459/2025) has taken effect; manufacturers and importers must comply by July 31, 2026, while retailers have a grace period until December 31, 2027; ② Consolidated Regulation on LED Lighting Fixtures (No. 231/2026, effective May 5, 2026; manufacturers have until November 5, 2027, to comply); ; ③ IT Equipment (No. 211/2026, issued in April 2026, strengthening OCP, traceability, and documentation); ④ Updates to helmets, fire extinguishers, and gas cylinders (No. 314/2025); Fans and air conditioners are currently under consultation for revision; commercial equipment, vending machines, and energy storage batteries are subject to new mandatory regulations. Please refer to the latest official Portaria for details.

IX. Summary

When exporting to Brazil, ”product compliance” is only the first step; ”valid certification + physical conformity with the certification + compliance with labeling, plug types, and Portuguese language requirements” are the keys to clearing customs. We recommend conducting a third-party inspection based on the above checklist **before shipment (during the PSI phase)** to ensure that the INMETRO mark, Portuguese labels, NBR 14136 plugs, model consistency, and document traceability at the factory to avoid the risk of detention, removal from shelves, and hefty fines once the goods arrive at the port.
