EMC — Bare Induction Motor (no integrated electronics) under ABNT/CISPR standards China does not impose a dedicated mandatory EMC standard on bare three-phase induction motors under CCC certification. For variable-speed drive systems, GB/T 12668.3-2012 (equivalent to IEC 61800-3:2004) governs EMC requirements and is a recommended (GB/T) standard, not a mandatory (GB) standard. Most standard industrial motors in China are not subject to compulsory EMC pre-market certification. The Brazilian situation for bare motors is similar — no dedicated mandatory EMC pre-market certification. The gap widens significantly when a VFD is integrated.GB/T 12668.3-2012 (equiv. IEC 61800-3:2004) — Adjustable speed electrical power drive systems, EMC requirements (recommended standard only)
No mandatory CCC EMC requirement for standard bare industrial three-phase motors		 A bare mains-fed three-phase induction motor with no integrated electronic control is generally a passive rotating machine and does not fall under specific INMETRO compulsory EMC certification requirements for motors in Brazil. Brazil adopts CISPR publications through ABNT (e.g., ABNT NBR CISPR 11, ABNT NBR CISPR 14) for industrial, scientific, and medical equipment and household appliances. For a bare industrial motor, no dedicated mandatory ABNT EMC Portaria equivalent to the EU EMC Directive has been identified as of the last-verified date. However, if the motor is sold with or integrated into a variable-frequency drive (VFD) or power-electronics-based system, the combined apparatus may be subject to INMETRO EMC requirements and the ABNT NBR IEC 61800-3 requirements for power drive systems.

ABNT NBR IEC 61800-3 — Adjustable speed electrical power drive systems — Part 3: EMC requirements (Brazilian adoption of IEC 61800-3; applicable to VFD-integrated motor systems)
Lei 9.933/1999 — General INMETRO compulsory certification law		 For a bare three-phase induction motor: both China and Brazil currently lack a dedicated mandatory EMC certification requirement, so the gap is minimal for bare motors. For motor+VFD integrated systems: Brazil requires compliance with ABNT NBR IEC 61800-3 and INMETRO may require compulsory certification for the combined apparatus. China's GB/T 12668.3-2012 is only a recommended standard and is based on the older IEC 61800-3:2004 (versus the current IEC 61800-3:2022). The gap for drive-integrated systems is material. Exporters shipping VFD-integrated motors to Brazil should verify the current INMETRO compulsory scope for power drive systems.[INFORMATIONAL] For a bare three-phase induction motor exported to Brazil, dedicated mandatory INMETRO EMC certification is not currently established, reducing the EMC-specific gap relative to China. For motor+VFD integrated systems, ABNT NBR IEC 61800-3 compliance and INMETRO compulsory certification for the combined apparatus may be required — verify scope with INMETRO DCONF before shipment. The VFD-integrated gap is significant and more closely parallels the EU EMC Directive situation. INMETRO — Instituto Nacional de Metrologia, Qualidade e Tecnologia (official)2026-06-12 · unverified
Minimum Energy Performance Standard — IR3 (Premium) mandatory threshold under Lei 10.295/2001 China's mandatory national standard GB 18613-2020 (三相异步电动机能效限定值及能效等级) defines three efficiency grades: Grade 3 (= IE3 = IR3) is the mandatory minimum since 1 June 2021; Grade 2 (= IE4) is the voluntary energy-saving evaluation level; Grade 1 (= IE5) is the highest tier. Both Brazil and China now require an IE3/IR3 floor for most three-phase motors, but the underlying limit values in ABNT/IEC and GB standards differ at some power/pole combinations. A motor meeting GB 18613-2020 Grade 3 must also be verified against the Brazilian ABNT/IEC 60034-30-1 limit values to confirm IR3 compliance.GB 18613-2020 (三相异步电动机能效限定值及能效等级, effective 2021-06-01)
GB/T 1032-2012 (三相异步电动机试验方法, aligned with IEC 60034-2-1 but with some differences in stray-load-loss treatment)		 Brazil established minimum energy performance standards (MEPS) for electric motors under Lei 10.295/2001 (the Energy Efficiency Law) and Decreto 4.059/2001, which empower INMETRO and the Ministry of Mines and Energy (MME) to set product-specific efficiency limits. For three-phase induction motors, INMETRO issued Portaria(s) establishing mandatory minimum efficiency levels. Since approximately 2019, IR3 (Premium Efficiency, equivalent to IEC IE3) has been the mandatory minimum for a broad range of three-phase induction motors sold or imported into Brazil, including motors in the approximate range of 1–375 kW. IR2 (High Efficiency, = IE2) was the prior MEPS level. The specific scope, rated-power boundaries, and exact Portaria number(s) in force should be verified directly with INMETRO's DCONF division before shipment. [Note: Exact Portaria number establishing current IR3 MEPS is listed in the INMETRO compulsory products catalogue — verify at inmetro.gov.br as Portaria numbering is subject to update.]Lei 10.295/2001 — Dispõe sobre a Política Nacional de Conservação e Uso Racional de Energia

ABNT NBR IEC 60034-30-1 (IE efficiency class definitions, Brazilian adoption)		 Both Brazil and China now set IR3/IE3 as the mandatory minimum for most three-phase induction motors. The headline floor is aligned. Key remaining gaps: (1) The exact numeric limit values in ABNT/IEC 60034-30-1 and GB 18613-2020 differ at certain power/pole combinations — a motor passing GB MEPS may not pass ABNT MEPS at the same operating point. (2) Efficiency testing methodology: GB/T 1032-2012 allows assumed stray-load losses in some methods, while IEC/ABNT 60034-2-1 requires measured values — CN test reports may overstate efficiency. (3) For Brazilian market entry, the motor must obtain INMETRO compulsory certification including testing through an INMETRO-accredited OCP (Organismo de Certificação de Produto) — Chinese test reports alone are not accepted.Chinese motors built to GB 18613-2020 Grade 3 (IE3) satisfy the IR3 efficiency floor in principle, but must be independently verified against ABNT/IEC 60034-30-1 numeric limits using IEC 60034-2-1 test methodology. For Brazilian market entry, INMETRO compulsory certification through an accredited OCP is required regardless of Chinese certification status. GB test reports alone are insufficient.

Efficiency measurement method — IEC 60034-2-1 (ABNT adoption) as the required test standard GB/T 1032-2012 (三相异步电动机试验方法) is the primary Chinese test method standard. It is substantially harmonised with IEC 60034-2-1 but permits an assumed stray-load-loss factor in Method B variants, whereas IEC 60034-2-1 requires measured stray losses (Method E or E2). This difference can result in Chinese test reports showing higher efficiency than the same motor tested per IEC 60034-2-1. GB/T 1032-tested results are therefore not automatically equivalent to ABNT NBR IEC 60034-2-1 results for INMETRO purposes.GB/T 1032-2012 (三相异步电动机试验方法, largely harmonised with IEC 60034-2-1 but with stray-load-loss differences)
GB 18613-2020 (references GB/T 1032 for efficiency measurement)		 Brazilian INMETRO certification for three-phase induction motors requires that efficiency values be determined using the Brazilian adoption of IEC 60034-2-1 (ABNT NBR IEC 60034-2-1, Methods for determining losses and efficiency of rotating electrical machines from tests). OCP-accredited testing laboratories in Brazil must apply this method when generating test reports for INMETRO conformity assessment. Test reports produced solely to GB/T 1032-2012 (the Chinese equivalent, which permits assumed stray-load losses in some test variants) are generally not directly accepted by INMETRO OCPs without verification of equivalence.ABNT NBR IEC 60034-2-1 — Máquinas elétricas rotativas — Parte 2-1: Métodos normalizados para determinação das perdas e do rendimento de máquinas elétricas rotativas (Brazilian adoption of IEC 60034-2-1)
IEC 60034-2-1 (Methods for determining losses and efficiency of rotating electrical machines from tests)		 A procedural and potentially technical gap: Chinese manufacturers must arrange testing at INMETRO-accredited OCP laboratories (or CGCRE-accredited labs accepted by the OCP) using ABNT NBR IEC 60034-2-1 method. Existing GB/T 1032 test certificates are not directly transferable. This means re-testing costs and lead-time must be planned for Brazilian market entry. The stray-load-loss treatment difference is the most likely source of divergence between Chinese and Brazilian test results for the same motor.Chinese test reports under GB/T 1032 alone are unlikely to satisfy INMETRO OCP documentation requirements. Exporters should budget for IEC 60034-2-1 compliant re-testing through an INMETRO-accredited OCP. This is a procedural barrier on top of the efficiency-level barrier and typically adds 3–6 months lead time.

Nameplate content and language — ABNT NBR 17094 and ABNT NBR IEC 60034-1 Portuguese-language nameplate Chinese three-phase motor nameplate requirements are set by GB/T 755-2019 (旋转电机 额定值和性能, equivalent to IEC 60034-1) and GB/T 13306-2011 (铭牌 — Nameplates general requirements). Required fields broadly overlap with IEC 60034-1: rated power (kW), voltage (V), current (A), frequency (Hz), poles/RPM, duty type (S1–S10), insulation class, IP class, and connection type. GB 18613-2020 additionally requires the efficiency grade (能效等级 1, 2, or 3) and efficiency value (η, %) to be marked on the nameplate, and the GB/T 28569-2012 energy efficiency label (中国能效标识) to be affixed to the motor. Chinese nameplates are printed in Chinese (Mandarin); GB/T 13306-2011 does not require Portuguese or any non-Chinese language. There is no equivalent Brazilian-facing seal or IR-class notation on standard Chinese nameplates.GB/T 755-2019 (旋转电机 额定值和性能, equivalent to IEC 60034-1 — nameplate clause)

GB/T 28569-2012 (中国能效标识格式 — energy efficiency label format for small and medium three-phase asynchronous motors)		 Three-phase induction motors sold in Brazil must carry a nameplate meeting the requirements of ABNT NBR 17094 (Máquinas elétricas girantes — Motores de indução trifásicos de baixa tensão) and the Brazilian adoption of IEC 60034-1 (ABNT NBR IEC 60034-1). The nameplate must be in Portuguese and include at minimum: manufacturer name or trademark, motor type/model designation, rated output power (kW), rated voltage(s) (V), rated current(s) (A), rated frequency (Hz), number of poles or synchronous speed (RPM), duty cycle (S1–S10), insulation class (e.g., F, H), IP protection degree (e.g., IP55), connection diagram or terminal marking (Δ/Y), serial number or production batch reference, country of manufacture, and the efficiency class (IR class: IR1, IR2, IR3, or IR4) with the corresponding efficiency value (η, %) at rated load. The INMETRO conformity mark (selo INMETRO) must also appear on the nameplate or be affixed to the motor body. ABNT periodically revises NBR 17094 — the current edition and any amendments should be confirmed at abnt.org.br before compliance assessment.ABNT NBR 17094 — Máquinas elétricas girantes — Motores de indução trifásicos de baixa tensão (nameplate clause; verify current edition at abnt.org.br)

INMETRO selo de identificação da conformidade — compulsory mark on nameplate for certified products		 Four specific labelling gaps exist for Chinese motors exported to Brazil: (1) Language — ABNT NBR 17094 and Brazilian supply practice require nameplate text in Portuguese; Chinese-only (Mandarin) nameplates do not comply. (2) IR efficiency class notation — Brazil requires the IR class (IR1/IR2/IR3/IR4) to be marked; Chinese nameplates use the GB grade (1/2/3), which correlates but uses a different notation system (GB Grade 3 = IE3 = IR3, but this must be explicitly converted and displayed in the Brazilian IR format). (3) INMETRO conformity mark — the INMETRO selo must appear on the nameplate or motor body; no equivalent Chinese domestic mark satisfies this requirement. (4) Energy label format — Brazil's INMETRO may specify a Brazilian motor energy-efficiency label format under applicable Portaria; the Chinese GB/T 28569 energy efficiency label is not recognised in Brazil. Chinese manufacturers exporting to Brazil must redesign or supplement nameplates to add Portuguese-language text, IR class notation, and the INMETRO selo before shipment.Chinese nameplates in Mandarin with GB grade notation (1/2/3) and the Chinese GB/T 28569 energy label do not meet Brazilian labelling requirements. Before shipment, exporters must ensure motors carry: a Portuguese-language nameplate with IR class and efficiency value, the INMETRO conformity mark, and any Brazilian energy-label format required under the applicable INMETRO Portaria. Nameplate redesign is typically required for every model entering the Brazilian market. ABNT — Associação Brasileira de Normas Técnicas (official)2026-06-12 · unverified
INMETRO Compulsory Certification — conformity mark and OCP assessment for three-phase induction motors Standard industrial three-phase induction motors are generally not subject to mandatory CCC (China Compulsory Certification) pre-market certification in China. The CNCA compulsory certification catalogue covers specific product categories (including some electrical equipment), but standard industrial three-phase motors fall outside the current compulsory CCC scope. Manufacturers must comply with the mandatory efficiency standard GB 18613-2020 for domestic sale, but no equivalent pre-market third-party certification body assessment is required before placing standard industrial motors on the Chinese domestic market. Export from China to Brazil does not benefit from any bilateral mutual recognition agreement with INMETRO.GB 18613-2020 (三相异步电动机能效限定值及能效等级 — mandatory minimum efficiency; no OCP pre-certification equivalent)
CNCA CCC compulsory catalogue (standard industrial three-phase motors generally not listed — verify current edition at cnca.gov.cn)		 Three-phase induction motors are included in the INMETRO compulsory certification scope under Brazil's national energy-efficiency and product-safety framework. The legal basis derives from Lei 10.295/2001 (National Energy Efficiency Policy), Decreto 4.059/2001, and Lei 9.933/1999 (which establishes INMETRO's general compulsory certification authority). INMETRO issues Portarias that list specific motor types and power ranges subject to compulsory certification. Before a motor can be commercially sold, distributed, or imported for use in Brazil, the manufacturer or importer must obtain an INMETRO certificate of conformity issued by an INMETRO-accredited OCP (Organismo de Certificação de Produto — Product Certification Body). The OCP must be accredited by CGCRE (INMETRO's accreditation arm). Testing must be performed at CGCRE-accredited laboratories applying ABNT NBR 17094, ABNT NBR IEC 60034-2-1, and the INMETRO-specified efficiency portaria. The certificate must be kept current and motors must carry the INMETRO conformity mark (selo de identificação da conformidade) on the nameplate or body. [Note: The specific Portaria number(s) establishing compulsory certification scope for three-phase induction motors — including power range boundaries — should be verified directly at inmetro.gov.br/dconf or the INMETRO compulsory products catalogue, as Portaria numbers are subject to revision.]Lei 9.933/1999 — Dispõe sobre as competências do INMETRO (general compulsory certification authority)

ABNT NBR IEC 60034-2-1 — Methods for determining losses and efficiency of rotating electrical machines		 This is the single most significant market-access gap for Chinese motor exporters to Brazil. China imposes no pre-market third-party OCP certification for standard industrial motors; Brazil mandates it. The gap has four dimensions: (1) Structural — an INMETRO-accredited OCP must assess the product; Chinese factory self-declarations or GB-based certificates are not accepted; (2) Testing — laboratory tests must be conducted or witnessed by the OCP at CGCRE-accredited labs applying ABNT standards; Chinese GB/T 1032 test reports are not directly transferable; (3) Timeline — OCP certification for a new motor type typically requires 4–9 months from sample submission to certificate issuance; (4) Ongoing obligation — the INMETRO certificate must be kept current, and production surveillance audits by the OCP are typically required annually. There is no mutual recognition treaty between INMETRO/CGCRE and Chinese CNAS-accredited labs or Chinese CB Scheme certificates for this product category.INMETRO compulsory certification through an accredited OCP is a non-negotiable prerequisite for placing three-phase induction motors on the Brazilian market. No Chinese certificate, test report, or mark substitutes for it. Exporters must engage an INMETRO-accredited OCP (verify current accredited OCPs at inmetro.gov.br), submit motor samples, complete testing at CGCRE-accredited labs under ABNT standards, and obtain and maintain the INMETRO certificate before first shipment. This process typically requires 4–9 months lead time. INMETRO — Instituto Nacional de Metrologia, Qualidade e Tecnologia (official)2026-06-12 · unverified
Import clearance — SISCOMEX registration, NCM classification, and II import duty for electric motors China has its own customs declaration system (GACC — General Administration of Customs of China) for export. Chinese exporters file an export customs declaration (出口报关单) under HS-aligned China Customs tariff codes; three-phase AC motors export under HS heading 8501.52 or related codes. No pre-export third-party registration equivalent to SISCOMEX exists. Chinese manufacturers exporting to Brazil are responsible for providing correct technical documentation (commercial invoice, packing list, certificate of origin, technical datasheet, and the INMETRO certificate) for Brazilian import clearance, but the Brazilian import process itself is the importer's obligation. China–Brazil trade is not covered by a preferential tariff agreement that reduces the standard Mercosur TEC rate for motors.China HS 8501.52 (three-phase AC motors export classification — GACC tariff schedule)
No SISCOMEX or equivalent pre-import registration system in China for motor exports		 Importing electric motors into Brazil requires compliance with the SISCOMEX (Sistema Integrado de Comércio Exterior) import registration system administered by the Secretaria Especial de Comércio Exterior e Assuntos Internacionais (SECEX) and the Receita Federal (Brazilian IRS). The importer must be registered in SISCOMEX and hold a valid RADAR (Sistema de Rastreamento da Atuação dos Intervenientes Aduaneiros) access licence. Electric motors are classified under NCM (Nomenclatura Comum do Mercosul, the Mercosur common tariff nomenclature, aligned with HS): three-phase AC induction motors commonly fall under NCM heading 8501.52 (AC motors, multi-phase, power exceeding 750 W but not exceeding 75 kW) or related headings depending on power rating. The Imposto de Importação (II — import duty) rate for electric motors varies by NCM subheading and may be subject to Mercosur common external tariff (TEC) rates and applicable trade agreements. The INMETRO conformity certificate is required as a supporting document at customs clearance — motors without a valid INMETRO certificate will be blocked at the border. Additionally, IPI (Imposto sobre Produtos Industrializados) and ICMS (state VAT) apply on importation. [Note: NCM classification, current II rates, and any applicable suspension (ex-tarifário) should be verified with a licensed customs broker (despachante aduaneiro) and through the Receita Federal / MDIC portals before shipment.]Decreto-Lei 37/1966 and Decreto 6.759/2009 — Brazilian Customs Regulation (Regulamento Aduaneiro)

Lei 9.933/1999 — INMETRO certificate required at customs for compulsory-certified products
SISCOMEX — Sistema Integrado de Comércio Exterior (administered by Receita Federal / MDIC)		 The Brazilian import clearance framework introduces three gaps relative to standard Chinese export practice: (1) SISCOMEX/RADAR — the Brazilian importer must have active SISCOMEX/RADAR registration; Chinese exporters cannot fulfil this obligation; (2) INMETRO certificate as customs document — the INMETRO certificate of conformity is a mandatory customs clearance document for compulsory-certified products; a motor shipped without this certificate will be detained at the Brazilian border; (3) Tax burden — Brazilian imports of electric motors attract the Mercosur TEC import duty rate on top of IPI and ICMS, increasing landed cost significantly compared with the Chinese domestic market. The NCM classification must be verified precisely because misclassification triggers penalties. China–Brazil have no FTA or preferential tariff scheme reducing the motor import duty.Chinese motor exporters must ensure the Brazilian importer holds SISCOMEX/RADAR registration and a current INMETRO certificate before shipment. A motor without a valid INMETRO certificate cannot clear Brazilian customs. Import duty rates under the Mercosur TEC and applicable taxes should be confirmed with a licensed Brazilian customs broker before pricing the transaction. No preferential tariff scheme between China and Brazil reduces the motor import duty burden. Presidência da República — Casa Civil (official Brazilian Customs Regulation)2026-06-12 · unverified
Rotating Machine Safety — ABNT NBR 17094 (Brazilian standard for rotating electrical machines) Chinese three-phase induction motors are governed by GB/T 755-2019 (旋转电机 额定值和性能, equivalent to IEC 60034-1), which specifies ratings, performance classes, temperature-rise limits, and insulation grades. IP protection follows GB/T 4942-2021 (aligned with IEC 60034-5). GB/T 755 and ABNT NBR IEC 60034-1 share IEC 60034-1 as a common technical basis, so motors designed to GB/T 755 typically meet the technical performance requirements of ABNT NBR 17094 and ABNT NBR IEC 60034-1. However, Chinese manufacturers must arrange testing and certification specifically to ABNT NBR 17094 through an INMETRO-accredited OCP — Chinese test certificates are not directly transferable.GB/T 755-2019 (旋转电机 额定值和性能, equivalent to IEC 60034-1)

GB/T 1032-2012 (三相异步电动机试验方法)		 Three-phase induction motors sold in Brazil must comply with ABNT NBR 17094 (Máquinas elétricas girantes — Motores de indução trifásicos de baixa tensão), the Brazilian standard for low-voltage three-phase induction motors. This standard covers ratings, performance, temperature limits, insulation classification, IP protection, and test methods for motors used in industrial applications. ABNT NBR 17094 is the primary Brazilian product safety standard for this category and is typically referenced in INMETRO compulsory certification requirements for motors. Parts 1 and 2 of ABNT NBR 17094 address general requirements and efficiency measurement respectively.

The primary gap is procedural: (1) INMETRO compulsory certification requires testing under ABNT NBR 17094 by an accredited OCP — Chinese test certificates issued under GB/T 755 are not directly accepted; (2) Brazilian certification documentation must be in Portuguese and issued by a CGCRE-accredited or INMETRO-recognized body; (3) the nameplate must carry the INMETRO conformity mark and meet Brazilian labelling requirements; (4) no mutual recognition agreement exists between Chinese CNAS-accredited labs and Brazilian CGCRE-accredited labs for motors.[INFORMATIONAL] Chinese motors designed to GB/T 755 / GB/T 4942 are likely to meet the technical requirements of ABNT NBR 17094 and ABNT NBR IEC 60034-1. However, Brazilian market entry requires INMETRO certification through an accredited OCP, Portuguese-language certification documentation, and INMETRO conformity mark on the nameplate. These procedural obligations must be met independently of Chinese certification history. ABNT — Associação Brasileira de Normas Técnicas (official)2026-06-12 · unverified
IP Protection Class and Insulation Grade — ABNT NBR IEC 60034-5 and nameplate declaration Chinese motors declare IP class per GB/T 4942-2021 (旋转电机整体结构的防护等级, aligned with IEC 60034-5) and insulation class per GB/T 755-2019. Since both GB/T 4942 and ABNT NBR IEC 60034-5 are national adoptions of IEC 60034-5, IP class designations (e.g., IP55) are technically equivalent. However, the testing must be conducted or witnessed by an INMETRO-accredited OCP for Brazilian certification — Chinese lab IP test reports are not automatically accepted.GB/T 4942-2021 (旋转电机整体结构的防护等级, aligned with IEC 60034-5)
GB/T 755-2019 (insulation class and temperature rise limits)		 Motors sold in Brazil must declare their IP (Ingress Protection) class per ABNT NBR IEC 60034-5 (Brazilian adoption of IEC 60034-5) and their insulation class per ABNT NBR IEC 60034-1. These values must appear on the motor nameplate. For INMETRO compulsory certification, the declared IP class must be verified through testing under accredited conditions. IP55 is a common minimum requirement for industrial environments in Brazil, though the specific requirement depends on the application and installation environment.ABNT NBR IEC 60034-5 — Máquinas elétricas rotativas — Parte 5: Graus de proteção do conjunto da máquina elétrica rotativa (Brazilian adoption of IEC 60034-5)
ABNT NBR IEC 60034-1 (insulation class and temperature limits)		 The technical requirements for IP class (via common IEC 60034-5 basis) and insulation class (via common IEC 60034-1 basis) are substantially equivalent between China and Brazil. The gap is primarily procedural: Brazilian INMETRO certification requires OCP-witnessed or OCP-conducted IP and insulation testing, with documentation in Portuguese. Chinese test certificates are not directly transferred.[INFORMATIONAL] IP and insulation class technical requirements are largely equivalent between China and Brazil due to the shared IEC 60034-1 / IEC 60034-5 base. However, INMETRO certification requires OCP-witnessed testing and Portuguese-language documentation. Chinese test reports for IP and insulation serve as technical background only and must be complemented by OCP-conducted certification.
