As the largest economy in Latin America, Brazil is also a major consumer market for lithium batteries worldwide. Electrical and electronic products exported to Brazil, including standalone lithium batteries and battery-powered finished devices, must obtain certification issued by Anatel (National Telecommunications Agency) or Inmetro (National Institute of Metrology, Standardization and Industrial Quality). Non-certified goods will be detained by customs and prohibited from local sales. This article comprehensively introduces standard requirements, test items, application procedures and practical tips for lithium battery Anatel certification.

1. Overview of Brazil’s Certification System for Electronic Products

Two primary authorities govern product compliance in Brazil:

Standalone lithium cells and battery packs mainly follow ABNT NBR IEC 62133-2 under the Inmetro framework, which is equivalent to IEC 62133-2:2017. Battery-powered finished products with built-in Bluetooth, Wi-Fi and other wireless modules are required to hold both Inmetro and Anatel certifications.

2. Core Applicable Standards

Key standards for lithium batteries exported to Brazil are listed below:

3. Core Test Items for Lithium Batteries

ABNT NBR IEC 62133-2 shares identical technical requirements with IEC 62133-2:2017. The 10 major test items are as follows:

1. Continuous low-rate overcharge test: Simulate abnormal long-term low-current charging to verify thermal stability and protection performance.
2. External short circuit test: Simulate short circuit between positive and negative terminals to confirm effective operation of protection circuits.
3. Forced discharge test: Keep charging fully depleted batteries to evaluate over-discharge protection mechanisms.
4. Mechanical impact test: Apply impact at specified G-force to check structural integrity.
5. Vibration test: Sine sweep vibration simulating transit conditions to assess vibration resistance.
6. Thermal exposure test: High-temperature exposure to verify thermal stability and prevent electrolyte leakage.
7. Temperature cycling test: Alternating high and low temperature cycles to ensure reliability of materials and internal connections.
8. Compression test: Apply specified pressure on single cells to evaluate shell strength and safety.
9. Over-current protection test: Simulate abnormal high current during charge and discharge to verify over-current protection functions.
10. Drop test: Free fall from 1.0 meter in multiple directions to examine drop resistance.

4. 6-Step Application Process for Anatel & Inmetro Certification

Step 1: Product classification and standard confirmation Identify product type (single cells, battery packs or wireless-enabled finished products) and confirm applicable standards: ABNT NBR IEC 62133-2 or Anatel Resolution 680.

Step 2: Select authorized laboratories Cooperate with OCP (Organismos de Certificação de Produto) accredited by Inmetro and Anatel. Pre-testing can be completed at qualified domestic laboratories.

Step 3: Sample testing Submit 6–12 test samples for full testing in accordance with ABNT standards. Obtain test reports issued in Portuguese.

Step 4: Document review by certification bodies Submit test reports and enterprise qualification documents for official review. For Anatel applications, additional RF compliance declarations are required.

Step 5: Factory audit (partial products) On-site factory inspection is mandatory for high-risk products to audit production consistency and quality management systems.

Step 6: Certification issuance & labelling compliance Affix Inmetro or Anatel marks on products after certification approval. Portuguese safety warnings and certificate numbers must be clearly printed on packaging.

5. Strategies to Accelerate Certification with CB Certificates

Manufacturers holding valid IEC 62133-2:2017 CB certificates can optimize the application process as below:

• Test data recognition: ABNT NBR IEC 62133-2 is technically equivalent to IEC 62133-2. OCP organizations can review existing CB reports, and only a small number of deviation tests are required.
• Cycle reduction: The overall lead time can be shortened from 12–16 weeks to 8–12 weeks with CB certificates.
• Cost saving via combined application: Apply for CB and ABNT NBR IEC 62133-2 simultaneously to share samples and test data, cutting total costs by approximately 30%–45%.
• Local agent support: Appoint a local Brazilian authorized agent to handle Inmetro and Anatel filing, to break down language and administrative barriers.

6. General Compliance Notes

• Portuguese labelling: Labels, user manuals and safety warnings must be provided in Portuguese. Non-compliant labelling will cause customs clearance failure even with valid certificates.
• Local importer CNPJ registration: Products sold in Brazil must be linked to a local importer with a valid CNPJ tax ID, and certificates shall be registered under the importer’s name.
• Certificate validity: Inmetro certificates are generally valid for 3–5 years. Renewal shall be applied before expiry. Re-certification assessment is required if product structure is modified.
• Dual certification for wireless devices: Finished products with wireless modules need both Anatel (RF compliance) and Inmetro (safety compliance) certifications. Neither can be omitted.
• Transport compliance: Lithium batteries exported to Brazil must comply with IATA/IMDG dangerous goods regulations. It is recommended to apply for UN 38.3 test reports in parallel.

7. Frequently Asked Questions (FAQ)

Q1: Is Anatel certification required for standalone lithium batteries without wireless functions? A1: Standalone cells and battery packs without wireless modules only need Inmetro certification complying with ABNT NBR IEC 62133-2. Anatel certification is only mandatory for finished products equipped with Bluetooth, Wi-Fi, cellular communication and other wireless modules.

Q2: What is the typical lead time for Anatel and Inmetro certification? A2: The standard process takes 10–16 weeks. The cycle can be reduced to 8–12 weeks if you hold a valid CB certificate. It is advised to launch certification preparation 4–5 months in advance to avoid shipment delays.
