Sellers of charging products targeting the Brazilian market have most likely heard of ANATEL certification, but many make a mistake at the very first step: either they assume all USB-C chargers require it, or they believe having CE and FCC reports allows direct sales, which may eventually lead to issues such as blocked import or customs clearance, or platforms requiring supplementary approval information. In fact, whether ANATEL applies to charging products cannot be judged solely by the interface or data transmission capability, but must be determined in combination with the product’s intended use, technical characteristics, ANATEL’s list of regulated products, and specific technical requirements. As long as you clarify the judgment criteria, application paths, and exclusive pitfalls, you can completely avoid unnecessary expenses and detours.
Quick Judgment on Whether Charging Products Require ANATEL Certification
This is the first step for beginners. Many people do not even figure out whether they need to apply before asking about the process, which is a pure waste of time.
Let’s first clarify the basic concept: ANATEL’s full name is the Brazilian National Telecommunications Agency, the official authority in Brazil responsible for market access management of telecommunications products, wireless devices, and related communication products. Its certification is a **mandatory type approval** — meaning products legally falling within the regulated scope must undergo prescribed conformity assessment and official approval before they can be legally commercialized in Brazil, and it is not sufficient to simply have testing done by any laboratory.
Charging Product Judgment Rules and Typical List
Many people think that whether a charging product requires ANATEL only depends on whether the interface is USB-C, whether it supports fast charging, or whether it can transmit data, but none of these are accurate enough. **Whether ANATEL approval is required shall be judged based on whether the product is a telecommunications product regulated by ANATEL, as well as the corresponding product list and technical requirements.**
Wireless communication devices usually require key verification against ANATEL requirements. For example, smart chargers with wireless communication functions such as Bluetooth and Wi-Fi, or wireless charging bases with communication functions that can exchange information with mobile phones or other devices, usually require ANATEL approval in accordance with applicable rules.
Ordinary USB chargers, passive USB cables, and products intended only for power supply usually do not automatically require ANATEL approval just because they have a USB interface or data pins. For products such as ordinary power plugs and basic power adapters, conclusions cannot be drawn solely based on the product name, and confirmation shall still be made based on whether the specific product falls under the scope of other mandatory regulations.
There are two boundaries where mistakes are most easily made, so they are specifically highlighted here.
The first is USB/USB-C charging cables. Do not simply assume that “having data pins means it is definitely regulated by ANATEL”, nor conversely assume that “focusing on charging means it definitely does not need approval”. Whether a USB cable is a telecommunications product regulated by ANATEL shall be confirmed in combination with its intended use, technical characteristics, and applicable product list. For ordinary passive cables, ANATEL approval is usually not triggered automatically just by the presence of data pins; if the product has active electronic components, communication functions, or other special uses, the OCD shall be requested to conduct pre-classification based on the specific model and technical documentation.
The second is wireless charging products. Whether wireless charging devices require ANATEL approval shall be confirmed based on their operating frequency band, emission characteristics, communication functions, and ANATEL product list, and cannot be judged solely by “whether it communicates with a mobile phone or APP”. Whether INMETRO certification is required also requires separate verification of whether the specific product falls under INMETRO’s mandatory conformity assessment scheme, and an absolute conclusion cannot be drawn solely based on “pure power supply”.
Core Differences from INMETRO Certification (Must-Read for Charging Products)
Many people confuse ANATEL and INMETRO, as both are important compliance authorities in Brazil. The core differences are clarified in the table below:
| Certification Type | Regulatory Focus | Applicable Scope for Charging Products |
| ANATEL | Compliance of regulated products such as telecommunications, wireless transmission, and communication | Wireless communication devices, telecommunications products, or other applicable products that specifically fall within ANATEL’s regulated scope |
| INMETRO | Conformity assessment of electrical safety, energy efficiency, plugs and sockets, etc., implemented in accordance with specific regulations | Chargers, power adapters, plugs and sockets, or other electrical products that fall under the corresponding INMETRO mandatory conformity assessment schemes |
In short, ANATEL and INMETRO are two separate regulatory systems and cannot replace each other. Only when a product is both a telecommunications product regulated by ANATEL and falls under the corresponding mandatory conformity assessment scope of INMETRO does it need to meet the two sets of requirements separately. You cannot conclude that a product necessarily requires dual certification just because it has wireless, USB, or data functions; a product may require ANATEL but not fall under INMETRO’s mandatory items, or may require INMETRO but not ANATEL.
Actual Consequences of Not Applying
Some people may think, I’ll just sell first and make up for it if I get caught. But if the product legally falls within the scope of ANATEL approval, failing to obtain approval may bring significant risks.
First, import or customs clearance may be blocked, and goods may be detained, returned, or subject to other disposal measures; second, products may face sales suspension, recall, confiscation, or administrative penalties; some e-commerce platforms may also require merchants to submit ANATEL approval information, and failure to provide it may result in sales restrictions or product removal.
The specific types of penalties, amounts, and implementation methods shall be judged based on applicable regulations, product conditions, import documentation, platform policies, and law enforcement decisions of regulatory authorities, and not all cases will result in a uniform fine based on the value of the goods. Whether entities such as the Brazilian local representative, applicant, manufacturer, and importer bear responsibility shall also be confirmed in combination with their legal status, application documents, and specific illegal acts, and cannot be generalized as all bearing joint and several liability.
Core Participants and Key Documents (Beginner’s Primer)
Applying for ANATEL certification is not a matter of submitting materials directly to the authority on your own. There are several fixed roles and three types of core documents involved in the process. Clarifying their respective functions first will help you understand the subsequent process.
Responsibilities of Core Participants
The entire process usually involves four types of roles, and the division of labor needs to be clarified in the application documents and contracts:
• **Applicant/Brand Owner**: That is you, responsible for providing product materials and samples, and bearing the primary responsibility related to product supply and compliance.
• **Brazilian local authorized representative or other legal participating entities**: The application shall be processed through the official system by an applicant entity that meets ANATEL regulations or its legal representative in Brazil, in accordance with the specific certification mode. The identity and responsibilities of the applicant, manufacturer, supplier, importer, and representative shall be clarified in the application documents. It cannot be generally asserted that all overseas entities are ineligible to apply, nor can it be assumed that as long as the representative is called an AR, they will necessarily bear joint and several liability.
• **Designated Certification Body (OCD)**: It is a third-party conformity assessment body accredited by ANATEL, responsible for reviewing materials, evaluating test plans and reports, and advancing approval applications in accordance with applicable procedures. It serves as an important reviewing party between enterprises and official requirements.
• **Accredited Laboratory**: In accordance with applicable projects and rules, a laboratory with corresponding qualifications is responsible for sample testing and issuing reports. Whether a specific type of accredited laboratory must be used shall be confirmed by the OCD in combination with the product category and applicable technical requirements.
Differences Between the Three Types of Core Documents
Three types of core documents will appear throughout the process, with completely different functions. Do not confuse them:
| Document Type | Issuing Party | Core Function | Can It Be Used Directly for Sales? |
| Test Report | Qualified testing laboratory | Proves that the sample has been tested in accordance with applicable requirements and records the results | No, it is only a record of test results |
| OCD Conformity Certificate | ANATEL-accredited conformity assessment body | Proves that product documentation, test results, etc. meet applicable assessment requirements | No, it is only an intermediate document submitted to the authority |
| ANATEL Approval Certificate | Brazilian National Telecommunications Agency | The final approval certificate issued by the authority, with a unique approval number | For products that legally require approval, it is an important access certificate for commercialization |
Classification of Charging Product Certification Categories
ANATEL product categories cannot be uniformly classified under “charging products”, and must be determined based on the specific product and applicable technical requirements.
Devices with radio frequency transmission functions such as Bluetooth and Wi-Fi shall usually be classified into corresponding radio frequency equipment categories in accordance with applicable rules. RF modules cannot be directly classified as Category III simply because they are “modules”. Category III usually applies to other products that neither belong to Category I nor Category II, but are still subject to corresponding technical requirements. The specific classification still depends on the product itself and applicable rules.
If a pure power supply product does not fall within the scope of ANATEL telecommunications products, ANATEL’s product category classification does not apply, but it still needs to be checked whether it falls under the scope of INMETRO or other Brazilian mandatory regulations.
Pre-Application Preparation: Paths, Materials, Cost and Timeline
This part is key to helping you avoid detours and save money and time. Planning in advance can avoid a lot of unnecessary trouble.
Two Common Application Paths (Exclusive for Charging Products)
Applying for ANATEL is not limited to the path of testing from scratch. Usually, different solutions can be selected based on existing materials and product conditions:
• **New Application Path**: If there is no acceptable existing test data, or the existing data cannot cover applicable requirements, it is necessary to start with sample testing and complete the subsequent conformity assessment and approval process.
• **Report Evaluation Path**: If you already have test or certification materials such as CB, CE RED, FCC, etc., you can submit them to the OCD for technical evaluation. Whether they can be accepted, which items can be reused, and whether supplementary testing is required shall be judged based on the qualification of the laboratory that issued the report, standard version, test configuration, product consistency, and ANATEL applicable rules. It cannot be promised that certificate conversion or test exemption will definitely be possible.
Which path to choose mainly depends on three factors: the functional complexity of the product, whether existing test materials meet applicable requirements, and your required launch timeline.
Series Certification Applicable Conditions (Key to Cost Reduction)
If you have several similar products, you do not need to apply for each one separately. You can ask whether you can apply as a series and package them into one series application, which can save a lot of money. But series certification has strict conditions, and you cannot merge products whenever you want:
• **Eligible for inclusion in the same series**: Usually requires the same core circuit (or core circuit sufficient to prove consistency), the same communication or wireless module, the same interface type, with only differences in output power, appearance color, or non-critical dimensions.
• **Not eligible for direct inclusion**: Changes that may affect applicable requirements, such as replacing the wireless chip or antenna, adding or removing data or wireless functions, or changing the USB interface type.
• **Special reminder**: Whether series certification is possible must be evaluated by the OCD in advance. Do not merge products privately, otherwise if the application is rejected during review, it will cause even more delay.
List of Basic Required Materials for Charging Products
Preparing materials in advance can reduce a lot of trouble with supplementary requests. The materials required for charging products are mainly divided into four categories:
1. **Product Materials**: Model specifications, appearance drawings, internal structure drawings, and materials that can explain the product’s intended use and functions. For USB-C charging cables, whether a cable core structure diagram needs to be provided shall be confirmed based on the OCD’s classification and review requirements.
2. **Test Materials**: If you already have international test or certification materials such as CB, CE RED, FCC, etc., you can provide them to the OCD to evaluate whether they can be accepted, reused, or require supplementary testing.
3. **Entity Materials**: Business license of the applicant, information of the manufacturer and supplier, and authorization documents of the Brazilian local representative where applicable.
4. **Labeling Materials**: Draft product nameplate, packaging design draft, first draft of Portuguese instruction manual, as well as product model and brand information.
Key Points for Selecting a Brazilian Local Representative
If your certification mode requires a Brazilian local representative or other Brazilian-based participating entities, you cannot only consider the quotation when choosing a partner.
Prioritize institutions that are familiar with ANATEL rules, understand the certification process for chargers and wireless devices, and can explain the respective responsibilities of the applicant entity, manufacturer, importer, and representative. Whether they hold a certain “ANATEL authorization qualification” shall also be verified against their legal role in the specific certification process, and you should not rely solely on the verbal claims of sales staff.
In addition, three matters must be clearly stipulated in the contract in advance: who controls the certificate and application materials, who is responsible for renewal or maintenance, and whether they will cooperate in the event of product changes. It is also necessary to agree on the handover of materials and arrangements for certificate use after the termination of cooperation, to avoid future disputes.
Cost and Timeline Estimation and Optimization Suggestions
Many people ask right away how much ANATEL certification costs and how long it takes. In fact, there is no fixed answer applicable to all products. It is mainly affected by several factors: product category and functional complexity, whether sample testing is required, whether existing reports can be accepted, the number of models in the same series, data completeness, laboratory scheduling, and official review status.
The timelines for the certificate conversion/report evaluation path and the new testing path shall be estimated by the OCD and the laboratory on a case-by-case basis. Market service providers sometimes give empirical ranges such as 6–10 weeks or 8–14 weeks, but these are not unified processing deadlines stipulated by ANATEL, nor can they be used as a guarantee of obtaining the certificate. In case of test rectification, supplementary materials, model changes, or official review delays, the timeline may be further extended.
For small and medium sellers, there are three optimization suggestions that can help you save money and time: First, plan general safety and EMC test materials in advance, which facilitates subsequent reuse evaluation by the OCD; second, apply as a package if series certification is possible, which is more cost-effective than applying separately; third, prepare the materials and mass-produced samples in advance, do not look for them temporarily when the application is about to start.
Complete Core Application Process (General for Charging Products + Checkpoints for Each Step)
The following is the complete application process. Each step clearly states what to do and what you need to obtain after completion to count as done (checkpoint). You can follow along.
Step 1: Product Classification and Path Confirmation
Do not rush to send samples in the first step. First, submit the product materials to the OCD for pre-evaluation, to confirm whether your product falls within ANATEL’s regulated scope, what product category and technical requirements apply, whether existing reports can be used, and whether series certification is possible.
If the product may also fall within the scope of INMETRO mandatory conformity assessment, the corresponding INMETRO items shall also be verified separately. You cannot assume that other certifications are already covered just because you are applying for ANATEL.
**Checkpoint**: Obtain an official classification and plan confirmation letter issued by the OCD. Do not trust verbal promises; there must be written documentation to avoid later changes.
Step 2: Sample Testing (Only Required for New Applications/Supplementary Testing)
If you take the new application path, or if some test items are still unacceptable after evaluation of existing reports, you need to send samples to a qualified laboratory for testing. Whether testing can be completed outside Brazil and which type of laboratory should issue the report shall also be confirmed in accordance with applicable rules and OCD requirements.
The test items for charging products are not uniform. Test content shall be determined according to product classification and applicable ANATEL technical requirements, which may involve radio frequency parameters, spectrum use, electromagnetic compatibility (EMC), and other applicable items. Whether USB protocol, data transmission rate, and electrical safety are tested shall be confirmed by the OCD based on the specific product and applicable regulations, and cannot be listed as unified core items for all charging products.
If wireless charging devices involve radio or electromagnetic emission characteristics, test items shall also be determined based on their operating frequency band, emission method, and specific technical requirements. When testing fails, common handling methods may include rectification, re-testing, or supplementary materials, and you cannot apply a single failure reason to all charging products in advance.
**Checkpoint**: Obtain a complete test report that meets applicable ANATEL requirements, with product model and test configuration consistent with the actual product.
Step 3: OCD Review and Conformity Confirmation
After obtaining the test report, the OCD will conduct a comprehensive review of your test report, technical materials, and labeling documents to confirm that all information is consistent and meets ANATEL requirements.
Common situations requiring supplementary materials include: inconsistent product parameters across documents, incomplete Portuguese materials, non-standard label format, inconsistent information between test samples and mass-produced models, etc. These can be avoided by paying attention in advance.
After passing the review, the OCD will issue a conformity document or certificate for subsequent approval applications. The specific name and form of the document shall be subject to the applicable certification mode.
**Checkpoint**: Verify the model, function, manufacturer, and applicable scope on the conformity document to ensure they are completely consistent with the product you actually sell. Do not write the wrong model, otherwise it will be unusable when needed.
Step 4: Submit ANATEL Approval and Pay Fees
This step shall be completed by an applicant entity that meets ANATEL regulations or its legal representative, submitting the application through the ANATEL official system in accordance with the specific certification mode. Who has the authority to submit and who acts as the applicant shall be subject to current rules and application documents, and it cannot be generally assumed that all overseas entities have no application authority.
Usually, the materials to be submitted include: OCD conformity document, applicable test reports, product materials, entity or authorization documents, and other materials required by the ANATEL system. At the same time, the corresponding official fees must be paid.
**Checkpoint**: Obtain application acceptance information or a receipt from the ANATEL system, proving that the application has entered the official process.
Step 5: Official Review and Certificate Issuance
There is no unified 4–6 week standard for ANATEL’s review time applicable to all charging products. The actual timeline will be affected by factors such as product category, completeness of application materials, OCD review status, need for supplementary materials, need for supplementary testing, and official work arrangements.
Common official reasons for requesting supplementary materials include: inconsistent product information across documents, insufficient test report coverage, mismatched model or manufacturer information, non-compliant labeling materials with applicable requirements, etc. Therefore, you must be careful when preparing materials in the earlier stages.
After passing the review, ANATEL will issue an electronic version of the approval certificate or approval information in accordance with applicable procedures, which will indicate the applicable product models and other relevant conditions.
**Checkpoint**: After receiving the certificate, be sure to check whether the product model, certificate holder, manufacturer, functional scope, and other conditions are consistent with the actual product. Do not ignore the certificate after receiving it; it will be troublesome if you find a mistake when it is time to launch the product.
Step 6: Pre-Marketing Labeling Confirmation
Obtaining the certificate is not the end. The labeling before marketing must also comply with ANATEL’s current rules and the approval conditions of the specific model, otherwise problems will still occur during spot checks.
Before marketing, the ANATEL logo and approval number shall be used in accordance with applicable labeling rules. The specific location, size, and form of the label, as well as whether packaging or instructions can be used for labeling, shall be confirmed by the OCD based on product category, product form, and current requirements. You cannot treat “must be printed on the body of all products” or “height of no less than 3mm” as a universally applicable standard for all charging products. Charging cables may especially be suitable for packaging or other labeling methods due to the size of the cable body and product form.
Product information in packaging and instructions shall also be provided in Portuguese in accordance with applicable requirements, and be consistent with the certificate and the physical product.
**Checkpoint**: Be sure to conduct the “five checks” before marketing — certificate, label, packaging, instruction manual, physical product. The information of these five must be completely consistent. Do not have one model on the certificate and another printed on the packaging.
Common Pitfalls and Avoidance Methods for Charging Products (Intermediate Advanced)
When applying for ANATEL certification for charging products, there are five most common pitfalls that almost every novice is prone to step into. Knowing them in advance can help you avoid them.
Pitfall 1: Misjudgment of USB-C Charging Cable Classification
Many people think that their cable is mainly for charging and only has data function by the way, so there is no need to apply for ANATEL; others think that as long as it has data pins, it must be applied for. Both judgments are too simplistic.
Whether a USB-C cable is a regulated product of ANATEL shall be confirmed in combination with whether it is a passive cable, whether it contains active electronic components, actual intended use, technical characteristics, and applicable product list, and cannot be judged only by the product name of “charging cable” or “data cable”.
**Avoidance Action**: Ask the supplier for the cable core structure diagram, chip information, and product use description in advance, or directly contact the OCD for pre-classification. Do not guess by yourself.
Pitfall 2: Using International Reports Directly as ANATEL Certification
Many people think that with CE, FCC, or CB reports, there is no need to apply for ANATEL and they can sell directly. In fact, these materials cannot automatically replace ANATEL approval, nor is there general automatic mutual recognition of CE or FCC reports.
Existing CB, CE RED, or FCC materials can be submitted to the OCD for technical evaluation. Whether they can be accepted, how much can be reused, and whether supplementary testing is required depends on the qualification of the laboratory that issued the report, standard version, test configuration, product consistency, and ANATEL applicable rules.
**Avoidance Action**: Send the international reports you have to the OCD in advance to evaluate how much can be reused, which can save some money, but the required processes still have to be followed.
Pitfall 3: Ignoring Compliance Requirements of Bundled Supporting Products
For example, if you sell a Bluetooth wireless charging base set that includes a regular charging head, many people think that as long as the wireless charging base passes ANATEL, the matching charger does not need to be considered. But in fact, whether the matching charger requires INMETRO certification depends on whether it falls under the corresponding mandatory conformity assessment scheme, and cannot be judged solely by the name “ordinary charger”.
If the wireless charging base in the set falls within the scope of ANATEL regulation, and the matching charger falls under INMETRO’s mandatory items, the set needs to meet the corresponding requirements separately when sold. Conversely, if one of the products is not within the corresponding mandatory scope, you cannot apply inapplicable certification conclusions just to “achieve dual certification”.
**Avoidance Action**: If selling as a set, be sure to plan ANATEL and INMETRO certification simultaneously in advance, confirm the applicable scope of each component separately, and do not have one component pass certification while the other fails to meet requirements.
Pitfall 4: Illegal Combination for Series Certification
Some people, in order to save money, merge charging products with different wireless versions and different interface types into one series for application, thinking that the OCD will not find out. But once discovered, not only will the application be rejected, but it may also affect subsequent certifications.
**Avoidance Action**: Send the list of products you want to include in the same series to the OCD for evaluation in advance. Only merge if they confirm it is allowed, and absolutely do not decide privately.
Pitfall 5: Unclear Certificate Control Rights
Many small and medium sellers do not have a local Brazilian company, so they find an importer as the relevant entity for application or certificate holding. As a result, after the cooperation ends, the importer refuses to cooperate with material handover or subsequent maintenance, so the money you spent before may no longer be effective, and the product may not be able to maintain sales smoothly.
**Avoidance Method**: If the certification mode allows, prioritize using a Brazilian entity that you can control; if not, be sure to clearly stipulate the right to use the certificate and application materials, handover arrangements, subsequent maintenance responsibilities, and cooperation obligations after the termination of cooperation in the contract. Also note that changing the applicant entity, certificate holder-related information, or other key entity information may require applying for a change, supplementary assessment, or re-certification with ANATEL, which shall be specifically confirmed by the OCD.
Post-Certification Maintenance and Validity Verification
Many people think that obtaining the certificate means everything is fine, but that is not the case. Subsequent maintenance is also very important, otherwise the certificate may become invalid, or even lead to penalties.
Certificate Validity Period and Renewal
Whether an ANATEL certificate has a validity period, how long the validity period is, and subsequent maintenance methods vary according to the certification mode, product category, certificate status, and applicable rules. The specific details shall be subject to the marking on the certificate and relevant procedural requirements.
You shall confirm the renewal or maintenance arrangement with the OCD in advance according to the validity period marked on the certificate. Do not treat “submitting 3–6 months before expiration” as a unified window applicable to all products.
If the product has undergone changes, it cannot be directly concluded that renewal is impossible. You should first explain the changes to the OCD, and let them judge whether supplementary testing, change submission, certificate update, or re-certification is required.
Compliance Judgment of Product Changes
It is inevitable to modify products when selling, but not all changes can be simply classified as “must be re-applied” or “only need to be filed”.
Any changes involving radio frequency modules, antennas, emission parameters, core circuits, interfaces, software functions, models, brands, or manufacturers shall be submitted to the OCD for written change evaluation before mass production and sales. The OCD shall determine whether it requires filing, supplementary testing, certificate change, or re-certification in accordance with applicable rules.
Changes such as appearance color and non-critical dimensions cannot be generally considered as only requiring filing; if they affect the model scope, product labeling, certificate information, or approval conditions, further processing may also be required. Brand labeling, model changes, and manufacturer information changes shall also be confirmed by the OCD first.
Special reminder: If you change the output power or fast charging protocol, be sure to contact the OCD in advance to evaluate whether it will affect the certification. Do not make changes on your own and sell directly.
Official Query Method for Certificate Validity
If you hired a service provider to handle the certificate, or if you want to verify whether a supplier’s certificate is real, you can directly go to the certificate query system on ANATEL’s official website to check, and enter the approval number, product model, or other information as required by the system to search.
When checking, mainly focus on three points: whether the certificate is still valid, whether the model is consistent with the actual product, and whether the certificate holder and manufacturer information match. If there are doubts about the certificate status, product version, or entity information, you should further confirm with the OCD or ANATEL to avoid obtaining a certificate that is not applicable to the current product.
Post-Marketing Compliance Precautions
After obtaining the certificate, you also need to pay attention to several things: First, keep compliance documents such as certificates, test reports, conformity documents, and change records properly for spot checks; second, cooperate with ANATEL’s market supervision spot checks; third, the labeling on e-commerce pages and product packaging shall be consistent with the certificate information, and do not write the approval number or model randomly.
Overall, it is not difficult to understand ANATEL certification, especially for charging products. You only need to master three core abilities: First, to judge whether a charging product requires ANATEL, first verify whether it is a telecommunications product regulated by ANATEL and meets the corresponding technical requirements. Wireless transmission is an important judgment factor, but “whether there is data transmission” is not the only standard applicable to all products; second, be able to prepare materials according to the process, choose the appropriate application path, and avoid the five exclusive pitfalls for charging products; third, be able to roughly estimate the application cost and timeline, verify the validity of the certificate, and conduct daily maintenance after obtaining the certificate. When doing business in the Brazilian market, compliance is always the first step. Planning in advance can help you avoid detours.
