Peers working the Brazil market mostly trip on this: the sample is shipped, testing is booked, and at the final step it stalls on paperwork — OCD sends it back with "incomplete documents," and re-queuing costs weeks. ANATEL is picky about documents, especially Portuguese materials and the authorisation chain; miss one and it does not move. This piece breaks the checklist into submission order — which is a hard gate, which depends on category.

1. Fix the certificate holder first

1.1 An overseas factory cannot apply directly

First hard rule. An overseas manufacturer cannot file in its own name; it must use a Brazil-incorporated company as the applicant, usually the importer or a compliance agent. Whoever the certificate is under owns the downstream compliance responsibility.

1.2 What the local representative carries

The local representative interfaces with ANATEL and the OCD, bears the legal liability of the application, plus the conformity maintenance, rectification and supervision work afterwards. Not a name-on-paper job.

1.3 Power of attorney and CNPJ

You need the local representative's qualification documents plus the manufacturer's formal power of attorney to them. The applicant must hold a valid CNPJ (Brazil corporate registration number); registered address and authorised signatory basics must be complete.

  2. The technical-file stack

2.1 Specification and drawings

Technical specification, circuit schematic, PCB layout — the basic three-piece set. Drawings clear, RF components marked where possible, and review rounds drop.

2.2 RF parameters listed separately

Radio-transmitting equipment additionally gives antenna gain, frequency range, transmit power. Keep a separate antenna-specification document; it is used later to assess whether the antenna can be changed.

2.3 Critical component list

RF module, battery and antenna models and suppliers all sit here. It ties to production consistency; changes must be declared, not filled in casually.

  3. Portuguese documents and photos

3.1 User manual must be Portuguese

The manual must have a Portuguese version, with safety warnings especially in Portuguese. English may be attached; pure Chinese is not accepted. People hit this every year, only realising at submission that translation is needed and losing the slot.

3.2 Label artwork draft

Submit the label design showing where the ANATEL mark and approval number go. The mark-usage rules have been adjusting lately; make the draft to current requirements, not by copying an old product's layout.

3.3 Real product photos

High-resolution shots of front, back, side and nameplate position. The unit must match the tested sample; if mass production changes the appearance, photos and certificate diverge.

  4. Test and system documents

4.1 Test-setup description

The most overlooked. Engineers use it to configure RF functions — how the software enters test mode and what parameters to set. Write it clearly to save communication.

4.2 ISO 9001 certificate

The manufacturer's quality-system certificate. It mainly supports Type 5 — the mode that audits the factory quality system, where ISO 9001 is a required element, not an independent "skip testing" switch. It only matters if you take Type 5; do not expect it to waive other modes' testing.

4.3 Sample quantity

Whole-device certification usually needs 2 to 4 mass-production samples. For the module-reference path, sample count follows the accepting OCD's requirement; some keep only a unit for document verification.

  5. Where the two paths differ in paperwork

5.1 Full whole-device certification

For the full-test route, not one item above can be missing. The report must come from a Brazil-accredited lab; your CE-RED or FCC report can serve as domestic pre-testing to find problems early, but it cannot stand in for the final report.

5.2 Module-reference simplified path

If the device's RF module holds a valid ANATEL certificate, it can be reused — the RF part is not re-tested, only EMC and safety assessment are done, compressing cycle and cost. But the premise is that the device's main function is not RF communication: an air conditioner with Wi-Fi counts as accessory and can reference; Bluetooth speakers and wireless gateways, where wireless is core, are mostly not accepted for reference by OCDs and must go whole-device. Provide the module certificate and specification additionally. (1) The antenna cannot move — that is one premise of module reference. (2) Firmware changes also need assessment. ① Even swapping the antenna supplier for one with seemingly identical specs, confirm with the OCD first whether it can carry over. ② If unsure which path, submit the module certificate and antenna info for assessment upfront rather than switching mid-route.

While we are at it, clarify the modes so planning is not wrong. Products are still classified by Categoria I/II/III (terminal, restricted radiation, other) — that is the product dimension. The certification mode is a separate set; the 2025 regulatory simplification (Act 2220-2222) introduced Type 1/4/5, taken by risk level. Type 1 does only type testing with no periodic maintenance; Type 4 adds periodic evaluation; Type 5 further adds factory quality-system audit (including ISO 9001). Type 4/5 certificates are usually valid 1 to 3 years and must be renewed, which bears on maintenance cost. Plan by the new modes, but keep the classification dimension.
