Brazil ANATEL Certification: How to pass South America's toughest certification?

Brazil is an important consumer electronics market in South America, and one with a relatively complex certification process. Two major regulators — ANATEL (National Telecommunications Agency) and INMETRO (Institute of Standards and Metrology) — each manage their own turf, so many factories can't figure out which one they need to do, and whether they can get around it. This article uses a 4-step judgment method to help you pin it down in 5 minutes.

First, understand what each regulator governs

ANATEL's three "pitfalls"

1. You must have a Brazilian local agent

ANATEL certification has to be held in the name of a Brazilian local company (legal representative or authorized agent). This is a fixed cost that can't be bypassed. No Brazilian agent = no ANATEL.

2. Type-C charging does not bypass ANATEL

Many people assume "Type-C charging = not mains = no certification needed". Wrong. ANATEL looks at whether there's RF transmission, not how you charge. As long as it has BLE/WiFi, you must do it.

3. Battery reports are a hard requirement for ANATEL review

During ANATEL review, they typically ask for the lithium battery's UN38.3 + IEC 62133 reports. If you haven't prepared these in advance, the project stalls. Get the battery reports in hand before you submit samples.

INMETRO: When is it actually needed?

In one sentence: once your product plugs into mains (AC), INMETRO may become mandatory.

• TWS earphones (DC battery + Type-C charging): does not trigger INMETRO
• USB-charged electric screwdriver (pure DC): usually does not trigger
• A charging dock made with an AC power adapter: triggers INMETRO
• AC mains-powered appliances: trigger INMETRO

Don't overlook the "standard package": UN38.3 + IEC 62133

For all lithium-battery products, UN38.3 is a transport must-have — required for all global air and sea shipping. The IEC 62133 cell safety report isn't officially mandatory, but ANATEL review and Brazilian channel partners almost always ask for it.

Summary: Brazil certification cost structure

1. ANATEL is a high-margin area: domestic factories are generally unfamiliar with it, the process is complex and the information gap is large, so there's substantial profit potential
2. The Brazilian agent is a fixed cost: you can't bypass it, but once established it's reusable
3. Renewals are steady revenue: ANATEL certificates are valid for 1-3 years; renewing on expiry is a continuous stream of business
4. Prepare the battery reports early: have UN38.3 and IEC 62133 ready first, to avoid stalling the ANATEL review
