INMETRO Certification in Brazil: Requirements, Process and Timelines
Key Points
- INMETRO certification is mandatory for a broad range of products sold in Brazil — electronics, appliances, automotive parts, toys, and PPE among them. Without it, goods can be detained or rejected at Brazilian ports.
- ANATEL certification is required for any device using radiofrequency — Bluetooth, Wi-Fi, LTE, 5G — and can only be held by a Brazilian-registered entity (CNPJ). Foreign manufacturers must work through a local representative.
- Certification timelines typically range from 3 to 6 months depending on product complexity and whether prior testing from ILAC-accredited labs can be accepted.
- INMETRO is currently reforming its framework to reduce redundant local testing through stronger alignment with international ILAC agreements — a development that benefits foreign manufacturers with existing compliance records.
- Both certifications are best managed in parallel with the import process — leaving them to the last stage is the most common cause of delays for companies entering Brazil.

Introduction
INMETRO certification in Brazil applies to hundreds of product categories — and getting it wrong is one of the most costly mistakes a foreign company can make during market entry. Products cleared by customs but sold without mandatory certification can be pulled from shelves, trigger fines, and damage the commercial relationships you spent months building.
This guide covers both INMETRO and ANATEL requirements, how they interact, what the certification timeline actually looks like in practice, and why the involvement of a local entity is not optional for ANATEL-regulated products. If you’re planning to import physical goods into Brazil — whether consumer electronics, medical devices, household appliances, or telecom equipment — this is the compliance groundwork you need to complete before your first shipment.
What Is INMETRO Certification in Brazil?
INMETRO (Instituto Nacional de Metrologia, Qualidade e Tecnologia) is Brazil’s national institute for metrology, standardization, and industrial quality. Its mandate covers product safety, reliability, and conformity for a wide range of consumer and industrial goods sold or imported into the country.
Brazil operates a dual certification structure: mandatory certification (compulsory by law) and voluntary certification (a market signal of quality). Products under mandatory scope must carry the INMETRO mark along with the mark of an accredited Conformity Assessment Body (OCP) before they can be sold. Products not covered by mandatory regulation may still pursue voluntary certification to strengthen their market positioning.
INMETRO is also Brazil’s national accreditation body, meaning it oversees the laboratories, certification bodies, and inspection organizations that conduct the actual conformity assessments. It operates within the ILAC Mutual Recognition Arrangement, which is increasingly relevant for foreign manufacturers whose products have already been tested by ILAC-accredited laboratories abroad — in many cases, those test results can be accepted without full retesting in Brazil.
Which Products Require INMETRO Certification?
The mandatory scope is extensive and evolves regularly through INMETRO ordinances (Portarias). For companies entering the Brazilian market, the practical starting point is to verify whether your specific product falls under a Portaria before engaging a certification body.
| Product Category | Examples | Certification Type |
|---|---|---|
| Electronics & Home Appliances | Refrigerators, televisions, air conditioners, lighting | Mandatory |
| Medical Devices | Electro-medical equipment, diagnostic devices | Mandatory |
| Automotive Parts | Tires, brakes, vehicle components | Mandatory |
| Construction Materials | Cement, steel rebar, structural elements | Mandatory |
| Toys & Children’s Products | Toys, playground equipment | Mandatory |
| Personal Protective Equipment | Helmets, gloves, safety harnesses | Mandatory |
| Industrial Equipment | Pressure vessels, measuring instruments | Varies by Portaria |
The official list of regulated products and applicable Portarias is maintained on INMETRO’s website. Product classification under the correct NCM/HS code is the first step — misclassification at this stage can misdirect the entire certification process. Novatrade covers this in detail in our article on the impact of NCM/HS code misclassifications.
The INMETRO Certification Process: Step by Step
The process is managed through an accredited Conformity Assessment Body (OCP or OCS) rather than directly through INMETRO. Choosing the right certification body for your product category is a meaningful decision — not all bodies are accredited for all product types, and their experience with your specific category affects both speed and cost.
Confirm whether your product is subject to mandatory certification and identify the applicable INMETRO Portaria. This determines testing standards, acceptable certification models, and documentation requirements.
Engage an OCP accredited by INMETRO for your product category. Bodies such as TÜV SÜD, UL Solutions, and Nemko operate locally in Brazil. Foreign manufacturers with existing ILAC-accredited test reports may be able to leverage them to reduce retesting requirements.
Product samples are submitted to an accredited laboratory for testing — electrical safety, mechanical performance, energy efficiency, and electromagnetic compatibility depending on category. Testing may be performed in Brazil or abroad (ILAC labs). A legal review period of 15 working days applies once documentation is submitted to INMETRO.
Many certification schemes require an on-site inspection at the manufacturing facility to verify production process compliance. Audits typically take around 5 working days. For medical devices, ISO 13485 QMS audits are often conducted simultaneously, reducing overall time and cost.
Once approved, the certification body issues the INMETRO certificate and authorization to use the compliance seal. INMETRO certificates have indefinite validity but require annual maintenance inspections and surveillance to remain active.
One practical consideration: some certification bodies allow testing and certification to proceed in parallel, which can shorten the overall timeline. Plan for 3 to 6 months for most product categories — longer for complex or high-risk products.
What Is ANATEL Certification in Brazil?
ANATEL (Agência Nacional de Telecomunicações) is Brazil’s national telecommunications regulator. Its certification requirement covers any device that uses radiofrequency for data transmission or reception — which in practice means a very broad range of products: smartphones, routers, IoT devices, industrial sensors, medical telemetry equipment, and anything else operating on Bluetooth, Wi-Fi, LTE, 5G, or other RF bands.
The scope is wider than many foreign companies expect. A product that doesn’t appear to be a “telecom device” — a connected machine tool, a wireless health monitor, a smart appliance — still requires ANATEL certification if it transmits or receives data wirelessly. This is frequently discovered too late, after products have already arrived in Brazil.
Understanding the full landscape of regulatory agencies in Brazil — INMETRO, ANATEL, ANVISA, MAPA — is covered in more depth in our guide to regulatory agencies in Brazil.
Key Requirements for ANATEL Certification
There are four structural requirements that define how ANATEL certification works for foreign manufacturers — and each one has practical implications for how you organize your market entry:
Local entity requirement. Only Brazilian-registered companies holding a CNPJ can obtain ANATEL certification. Foreign manufacturers cannot apply directly. This means you must work through a local entity — either your own Brazilian subsidiary or a local service provider acting as legal representative.
Non-transferability. ANATEL certification is issued to a specific importer, not to the product. Even if the same device has been certified by ANATEL for another importer, or has received equivalent certification in Europe or the US, a new certification must be obtained for each importer bringing the product into Brazil.
Accredited testing bodies (OCDs). Testing and compliance verification are conducted through ANATEL-accredited organizations (OCDs), which oversee compatibility with Brazilian network standards, signal quality, and safety requirements. Testing can often leverage existing international certifications, depending on the frequency bands and standards involved.
Mandatory labeling. Certified products must carry the ANATEL homologation label with a unique identification number that can be verified on ANATEL’s public database. This labeling is required both on the product and in accompanying documentation.
For companies without a local Brazilian entity, Novatrade’s Importer of Record (IOR) service provides the legal structure needed to hold ANATEL certification on your behalf — allowing you to import and sell in Brazil without setting up a subsidiary.
Timelines and Costs to Plan For
The most consistent mistake in planning a Brazil product launch is treating regulatory certification as something to finalize after other elements are in place. Both INMETRO and ANATEL processes have significant lead times, and any issue discovered during testing — a failed standard, a documentation gap, a factory audit finding — resets the clock.
Running INMETRO and ANATEL processes in parallel — coordinated through a single local partner — is the most effective way to compress the overall timeline. Products that require both certifications should begin this process at least 6 months before the planned market launch date.
Working with a Local Partner in Brazil
For foreign companies, the most common source of delays is not the certification standards themselves — it’s the administrative and legal infrastructure required to navigate the process in Brazil. ANATEL’s CNPJ requirement makes a local entity structurally mandatory. INMETRO’s factory audit and documentation requirements benefit significantly from local expertise in Portuguese-language regulatory procedures.
The choice of how to establish that local presence matters. Importing under MAPA and ANVISA guidelines involves a similar structure — a local entity that holds the necessary registrations and acts as the legal interface with regulators. The same logic applies to INMETRO and ANATEL: your local partner is not just a logistics facilitator, it’s the legal holder of your market access rights.

Frequently Asked Questions
Is INMETRO certification mandatory for all products imported into Brazil?
No — INMETRO certification is mandatory only for products listed under specific INMETRO Portarias (ordinances). These include electronics, appliances, automotive parts, toys, medical devices, and PPE, among others. Products not covered by a Portaria may still obtain voluntary certification but are not legally required to do so. Confirming whether your product falls under mandatory scope before beginning the import process is the first step.
Can a foreign company obtain ANATEL certification directly?
No. ANATEL certification can only be held by a Brazilian-registered legal entity with a CNPJ. Foreign manufacturers must work through a local Brazilian company — either their own subsidiary or a service provider acting as legal representative. This is a structural requirement, not an administrative preference, and applies regardless of certifications the product may hold in other markets.
If our product is already certified in Europe or the US, does Brazil accept those test results?
Potentially, yes. INMETRO is a signatory to the ILAC Mutual Recognition Arrangement, which means test results from ILAC-accredited laboratories abroad may be accepted without full retesting in Brazil. However, acceptance depends on the specific Portaria, the testing standard used, and whether the foreign lab is ILAC-accredited. A gap assessment by an accredited certification body is the practical first step. ANATEL has separate criteria for accepting foreign RF certifications.
How long does INMETRO certification take?
For most product categories, the process takes 3 to 6 months from the point of engaging an accredited certification body. Medical devices typically take longer — 5 to 9 months — due to the additional ISO 13485 audit requirement under Portaria 384/2020. Products where existing ILAC-accredited test data can be accepted tend to move faster. Planning the certification process at least 6 months before your intended launch date is advisable.
What types of products require ANATEL certification?
Any product that transmits or receives data using radiofrequency requires ANATEL homologation. This includes obvious categories like smartphones, routers, and tablets, but also IoT devices, wireless industrial equipment, connected medical devices, smart appliances, and anything with Bluetooth, Wi-Fi, LTE, or 5G functionality. The scope is broader than most foreign manufacturers expect — a product audit against ANATEL’s product catalogue is the safest way to confirm scope before planning your import.
What happens if a product is sold in Brazil without INMETRO or ANATEL certification?
Products sold without mandatory INMETRO certification can be seized by PROCON or INMETRO inspectors, subject to fines, and require recall from market. Non-certified ANATEL products face similar enforcement, including customs detention, fines, and mandatory removal from distribution. Beyond regulatory penalties, distribution partners in Brazil typically require proof of certification before agreeing to carry a product — making certification a commercial prerequisite as much as a legal one.
Conclusion
INMETRO and ANATEL certification are not administrative hurdles to clear at the end of a market entry project — they are structural requirements that shape the timeline and legal setup from the beginning. The CNPJ requirement for ANATEL alone means that companies without a local entity in Brazil need to resolve that question before certification can begin.
The good news is that Brazil’s certification framework has been moving toward greater alignment with international standards, and companies with solid compliance records in Europe or the US often find that existing test data can accelerate the process. The key is starting early and working with a partner who knows which certification bodies to engage for your specific product category.
