Market access / certification — PSE mark (Electrical Appliance and Material Safety Act) applicability In China, the CCC (China Compulsory Certification) scheme administered by CNCA covers electrical products in mandatory categories. General industrial three-phase induction motors are NOT currently in the mandatory CCC catalogue — domestic sale does not require CCC. This is structurally analogous to Japan's DENAN situation: neither country imposes a mandatory third-party product certification scheme on standard industrial-grade three-phase AC motors. Both rely on compliance with technical standards (GB in China, JIS/IEC in Japan) rather than mandatory product certification for this product category.CCC (China Compulsory Certification) catalogue — industrial three-phase motors not currently listed as mandatory The Electrical Appliance and Material Safety Act (電気用品安全法, DENAN, Act No. 234 of 1961, as amended) regulates electrical appliances and materials sold in Japan. Products are listed in two categories: 'Specified Electrical Appliances and Materials' (特定電気用品, requiring third-party conformity certification — PSE diamond mark 菱形PSE) and 'Non-specified Electrical Appliances and Materials' (非特定電気用品, self-declaration — PSE circle mark 丸形PSE). Three-phase AC induction motors for industrial use (typically above 200 V, used in industrial machinery) are GENERALLY NOT listed in the DENAN schedules as regulated electrical appliances — meaning DENAN / PSE requirements do NOT apply to most industrial three-phase motors. [UNCERTAINTY FLAG: The DENAN scope lists should be verified for the specific motor type, voltage, and end-use application; some lower-voltage motors or motors incorporated into consumer products may fall under DENAN.] METI administers DENAN.Electrical Appliance and Material Safety Act (電気用品安全法, DENAN, Act No. 234 of 1961, as amended)
METI DENAN product schedules (Appended Table 1 — Specified; Appended Table 2 — Non-specified)		 For standard industrial three-phase induction motors (200 V+, used in industrial machinery), Japan's DENAN / PSE scheme does not apply — there is no mandatory third-party product certification barrier equivalent to CE marking in the EU. This is a smaller gap than for EU or UK export. The primary market-access mechanisms for Japan are Top Runner efficiency compliance (mandatory, see motorjp-efficiency) and meeting JIS C 4034 technical parameters (de facto expectation). [UNCERTAINTY FLAG: Always verify the current DENAN product schedules on METI's official portal before final compliance determination, as schedules can be amended. The applicability to specific low-voltage single-phase motor variants or motors sold for consumer/household use may differ.][INFORMATIONAL] Most industrial three-phase induction motors do not require PSE / DENAN certification for Japan market access. The mandatory market-access barrier is Top Runner efficiency compliance under 省エネ法. Exporters should verify the current DENAN product schedules on METI's official portal to confirm their specific motor model and voltage rating are out of scope. Do not rely on this comparison alone for final compliance determination. Ministry of Economy, Trade and Industry (METI) Japan2026-06-12 · unverified
Top Runner importer registration and designated manufacturer obligations China has no equivalent importer registration or annual energy-efficiency reporting scheme for motors. GB 18613-2020 compliance is enforced through product quality supervision by SAMR/CQC at the manufacturer level. There is no statutory duty on importers of motors into China to register with an energy authority or file annual efficiency compliance reports.GB 18613-2020 (enforced by SAMR at manufacturer level — no equivalent import registration duty) Under the Act on Rationalizing Energy Use (省エネ法), entities that import Top Runner designated products (including three-phase induction motors) into Japan for sale are classified as 'Specified Import Businesses' (特定輸入業者) and must register with METI/ANRE, meet the Top Runner target efficiency values, maintain performance records, and submit annual compliance reports. Foreign manufacturers selling directly to Japan through an importer must ensure their importer fulfils these obligations. This is a procedural market-access requirement with no equivalent in Chinese domestic regulations.Act on Rationalizing Energy Use (省エネ法, Law No. 49 of 1979, as amended) — Specified Import Business provisions
ANRE (Agency for Natural Resources and Energy) administrative guidance on Top Runner designated products		 The importer registration and annual reporting obligation under 省エネ法 is a procedural gap with no Chinese equivalent. Chinese motor exporters whose Japanese buyers are classified as 'Specified Import Businesses' must ensure: (1) their buyer is registered with ANRE/METI; (2) product efficiency documentation (Top Runner target values, test reports under JIS C 4034-2-1) is supplied to support the importer's annual report; (3) product specifications are maintained and updated if METI revises target values. Failure by the importer to comply can result in METI issuing an improvement order and, ultimately, public disclosure of non-compliance — reputational and commercial risk for both importer and supplier.Chinese motor exporters must work with their Japanese importer to confirm the importer's registration as a Specified Import Business under 省エネ法 and provide the efficiency test documentation required for the importer's annual compliance report to ANRE/METI. This is a supply-chain procedural obligation that sits above and apart from the technical Top Runner efficiency compliance.

Top Runner Program — mandatory IE3-equivalent minimum efficiency (Act on Rationalizing Energy Use) 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, effective 1 June 2021) sets Grade 3 (= IE3) as the mandatory minimum efficiency for most three-phase induction motors. This is substantively equivalent to Japan's Top Runner IE3-equivalent target. The Chinese mandatory scope covers a similar power range. GB 18613-2020 also defines Grade 2 (= IE4) as the voluntary energy-saving evaluation level and Grade 1 (= IE5) as the highest tier. Test methods are specified in GB/T 1032-2023.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 1032-2023 (三相异步电动机试验方法)		 Japan's Top Runner Program (省エネ法 / Act on Rationalizing Energy Use, Law No. 49 of 1979, as amended) sets mandatory target efficiency values for three-phase induction motors. Three-phase cage induction motors rated 0.75 kW to 375 kW are designated products under the program. Since fiscal year 2015, manufacturers and importers must ensure their products meet or exceed the Top Runner target values, which correspond to IEC 60034-30 IE3 (Premium Efficiency) class for most power/pole combinations. The target values are set by the Minister of Economy, Trade and Industry (METI) under the Act. Non-compliant products may not be sold in Japan by regulated entities.Act on Rationalizing Energy Use (省エネ法, Law No. 49 of 1979, as amended)
METI Ministerial Order specifying Top Runner target values for motors
JIS C 4034-30-1 (aligns with IEC 60034-30-1 — efficiency classes IE1/IE2/IE3)
JIS C 4212 (High-efficiency three-phase cage induction motors)		 The headline efficiency floor is broadly aligned: both Japan Top Runner and GB 18613-2020 require IE3-equivalent performance. The key gaps are: (1) Numeric target values — Japan's Top Runner target values are defined in METI orders referencing JIS C 4034-30-1 / IEC 60034-30-1; GB 18613-2020 limits are based on a separate Chinese derivation and are not identical for all power/pole combinations. A motor meeting GB 18613-2020 Grade 3 may not precisely meet every Japan Top Runner target value at specific operating points. Independent verification against Japan's published target values (in METI ministerial orders) is needed. (2) Test method: Japan references JIS C 4034-2-1 (aligned with IEC 60034-2-1) for efficiency determination, while China uses GB/T 1032-2023, which may allow assumed stray-load losses in some test methods — potentially yielding higher efficiency figures than under JIS/IEC methods. (3) Importer reporting duty under 省エネ法 (see motorjp-labelling fragment) — no Chinese equivalent.Chinese motors certified to GB 18613-2020 Grade 3 (IE3) are likely to meet Japan's Top Runner IE3-equivalent efficiency floor for most power/pole combinations, but must be verified against Japan's published Top Runner target values in METI ministerial orders using JIS C 4034-2-1 (IEC 60034-2-1 aligned) test data. GB/T 1032-tested results may not be directly accepted without methodology verification. Importers also bear a statutory reporting duty under 省エネ法 that has no counterpart in Chinese domestic requirements. Agency for Natural Resources and Energy (ANRE), METI Japan2026-06-12 · unverified
Top Runner efficiency test method — JIS C 4034-2-1 (aligned with IEC 60034-2-1) GB/T 1032-2023 (三相异步电动机试验方法) is substantially harmonised with IEC 60034-2-1 but permits an assumed stray-load-loss factor in Method B (the most commonly used method in Chinese factories), whereas IEC/JIS 60034-2-1 Method B requires measured stray losses. This can result in GB/T 1032-tested motors reporting efficiency values 0.2–0.5 percentage points higher than under JIS/IEC testing — meaning a motor borderline at Grade 3 in GB/T 1032 testing might narrowly fall below Japan Top Runner target values when re-tested under JIS C 4034-2-1.GB/T 1032-2023 (三相异步电动机试验方法) Efficiency values submitted for Top Runner compliance and nameplate declaration in Japan must be determined in accordance with JIS C 4034-2-1 (Methods for determining losses and efficiency of rotating electrical machines from tests), which is the Japanese adoption of IEC 60034-2-1. This requires measured stray-load losses and does not permit the assumed-value approach for stray-load losses allowed in some older or alternative test methods. Efficiency class assignment follows JIS C 4034-30 (adoption of IEC 60034-30-1).JIS C 4034-2-1 (Methods for determining losses and efficiency — adoption of IEC 60034-2-1)
JIS C 4034-30 (Efficiency classes — adoption of IEC 60034-30-1)
Act on Rationalizing Energy Use (省エネ法) implementing ordinances		 Test methodology divergence between GB/T 1032 (assumed stray-load loss permitted) and JIS C 4034-2-1 (measured stray-load loss required) is the key measurement gap. Motors tested under GB/T 1032 Method B using assumed stray losses may report efficiency 0.2–0.5 percentage points above their true IEC/JIS value. Borderline IE3 motors risk failing Japan Top Runner target values upon re-testing under JIS C 4034-2-1. Exporters should obtain JIS C 4034-2-1 compliant test data from an accredited laboratory before declaring Top Runner compliance.Chinese test reports under GB/T 1032 Method B with assumed stray-load losses may not be directly accepted as proof of Japan Top Runner target compliance. Re-testing under JIS C 4034-2-1 at an accredited laboratory is advisable for all motors, and essential for motors near the IE3 boundary.

EMC / Radio interference — Radio Law (電波法) and VCCI applicability to industrial motors In China, EMC requirements for industrial equipment are addressed by GB/T 17626 series (immunity, aligned with IEC 61000-4 series) and GB 17625 series (conducted/radiated emissions). Bare industrial motors are generally not subject to mandatory CCC certification for EMC; however, complete motor-drive systems with inverters may require CCC EMC testing. There is no Chinese mandatory standalone EMC certification for bare three-phase induction motors sold industrially, which is broadly analogous to the Japanese situation.GB/T 17626 series (EMC immunity, aligned with IEC 61000-4)
GB 17625 series (conducted and radiated emissions)		 Japan does not impose a mandatory standalone EMC certification requirement on bare three-phase induction motors equivalent to the EU's EMC Directive. The applicable regulatory framework is: (1) Radio Law (電波法, Act No. 131 of 1950) — prohibits radiation of radio waves that cause harmful interference; applies to equipment that intentionally or unintentionally emits radio waves above regulated limits; bare AC induction motors without integrated electronic control are generally not regulated products under the Radio Law. (2) VCCI (Voluntary Control Council for Interference by Information Technology Equipment) — a voluntary industry organisation that sets EMC limits for IT equipment; industrial motors are outside VCCI scope. (3) Variable-speed drives (inverters / VFDs) connected to motors are a different matter: the power conversion equipment itself may be subject to Radio Law requirements or VCCI registration if it falls within defined scope. Importers and system integrators should assess EMC of the complete motor-drive system, not just the bare motor.Radio Law (電波法, Act No. 131 of 1950, as amended) — enforced by Ministry of Internal Affairs and Communications (MIC)
VCCI guidelines (voluntary, IT equipment focus — industrial motors out of scope)
CISPR 11 / JIS C 61000 series (referenced for industrial RF emissions where applicable)		 For bare three-phase induction motors without integrated electronics, Japan has no mandatory standalone EMC certification — this is a narrower gap versus EU (which requires CE EMC marking) and is broadly similar to the Chinese domestic situation. The gap exists at the system level: when motors are operated with variable-speed drives (VFDs/inverters), the combined system's conducted and radiated emissions must comply with Radio Law limits, and the VFD itself may require Radio Law type approval or VCCI registration depending on its power/frequency profile and product category. Exporters selling motors as part of drive systems must assess system-level EMC. [FLAG: Mandatory-vs-voluntary uncertainty — the applicability of Radio Law to specific VFD configurations and power levels should be verified with a Japan-registered electrical safety consultant or the Ministry of Internal Affairs and Communications (MIC).][INFORMATIONAL] Bare three-phase induction motors exported from China to Japan face no mandatory standalone EMC certification requirement. This is a smaller gap than for EU export. However, when the motor is sold as part of a system with a VFD/inverter, the system's Radio Law EMC compliance must be assessed. Exporters of motor-drive combinations should verify Radio Law applicability for their specific product category with a Japan-qualified specialist. VCCI is not applicable to industrial motors.

Nameplate requirements — JIS C 4034 and Top Runner efficiency class marking GB 755-2019 specifies nameplate requirements for rotating machines in China, aligned with IEC 60034-1. Chinese motors are required to display rated output, voltage, current, frequency, speed, insulation class, duty, IP class, and efficiency or efficiency grade on the nameplate. GB 18613-2020 additionally requires the energy efficiency grade (1/2/3) to be marked where the motor is subject to the mandatory minimum efficiency standard. The nameplate content requirements under GB 755 and JIS C 4034-1 are very similar due to their common IEC 60034-1 basis.GB 755-2019 (nameplate requirements, equivalent to IEC 60034-1)
GB 18613-2020 (energy efficiency grade marking on nameplate)		 Motors sold in Japan must carry a nameplate declaring rated output (kW), rated voltage (V), rated frequency (Hz), rated current (A), rated speed (rpm), insulation class, IP protection class, duty type, and efficiency or efficiency class. JIS C 4034-1 specifies the minimum nameplate information for rotating machines. For Top Runner compliance, motors must be able to demonstrate their efficiency class (IE2/IE3 or equivalent Top Runner target) either on the nameplate or in accompanying technical documentation. JIS C 4034-30 defines the efficiency class designations (IE1/IE2/IE3) that should be referenced. There is no mandatory separate energy label (comparable to EU energy label) required for industrial motors in Japan — efficiency compliance is demonstrated through technical documentation rather than a consumer-facing label.JIS C 4034-1 (Nameplate requirements — adoption of IEC 60034-1)
JIS C 4034-30 (Efficiency class designations IE1/IE2/IE3 — adoption of IEC 60034-30-1)
Act on Rationalizing Energy Use (省エネ法) — technical documentation obligations for Top Runner designated products		 Nameplate technical content is closely aligned between GB 755 and JIS C 4034-1 (both derive from IEC 60034-1). Key practical gaps: (1) Language — nameplates in Japan typically display information in Japanese; although JIS C 4034-1 does not mandate a specific language, Japanese buyers and inspectors expect Japanese-language labelling for key parameters. Chinese-language-only nameplates may not be accepted in procurement. (2) Efficiency class notation — GB 18613-2020 uses Grade 1/2/3 (能效等级 1/2/3) while Japan uses IE1/IE2/IE3 notation per JIS C 4034-30; the nameplate or documentation for Japan should declare IE class, not GB grade, or provide a clear cross-reference. (3) Frequency — Japan uses 50 Hz (eastern Japan) and 60 Hz (western Japan); a motor nameplate must correctly state the rated frequency. Chinese-made motors for China are typically 50 Hz only — dual-frequency or 60 Hz variants need separate validation for western Japan. (4) No energy label — Japan does not require the type of visible consumer-facing energy efficiency label mandated for motors in some other markets (EU, Australia); technical documents suffice.[INFORMATIONAL] Chinese motors with GB 755-compliant nameplates are close to meeting JIS C 4034-1 nameplate requirements, but exporters must: (1) provide Japanese-language labelling or bilingual (Chinese/Japanese) nameplates for Japan market products; (2) express efficiency class as IE2/IE3 (JIS C 4034-30 notation) rather than GB grade 2/3; (3) verify and correctly state rated frequency, including whether motors are suitable for 60 Hz operation in western Japan. No separate consumer energy label is required. Japanese Industrial Standards Committee (JISC), METI Japan2026-06-12 · unverified
Top Runner annual reporting duty — importer's energy performance submission to ANRE China has no equivalent annual energy-efficiency reporting obligation for motor importers or manufacturers. Compliance with GB 18613-2020 is enforced through product quality supervision by SAMR, not through an ongoing self-reporting duty. The energy-efficiency labelling scheme (节能产品认证, administered by CQC) is voluntary.GB 18613-2020 (enforcement by SAMR — no equivalent annual reporting duty)
节能产品认证 (CQC voluntary energy-saving product certification — voluntary)		 Under the Act on Rationalizing Energy Use (省エネ法), Specified Import Businesses importing Top Runner designated motors must submit an annual report to the Agency for Natural Resources and Energy (ANRE) detailing the energy efficiency performance of imported models and demonstrating compliance with Top Runner target values. The report must cover model names, rated output, efficiency values (per JIS C 4034-2-1 test method), and aggregated import volumes. ANRE reviews submissions and may issue an improvement order (勧告) or publish non-compliant entity names if targets are missed. This reporting cycle is an ongoing annual obligation, not a one-time pre-market approval.Act on Rationalizing Energy Use (省エネ法, Law No. 49 of 1979, as amended) — Chapter IV Specified Import Business provisions
ANRE Top Runner Program administrative instructions for motors		 The annual reporting obligation under 省エネ法 is a structural gap with no Chinese counterpart. Chinese exporters must supply their Japanese importer with: (1) efficiency test reports under JIS C 4034-2-1 for each model; (2) model specifications and rated output data; (3) timely updates if product specifications change. Failure to provide documentation may prevent the importer from completing its annual ANRE submission, creating a supply chain compliance risk. Exporters should build this documentation supply into their Japan sales agreements.The annual Top Runner reporting obligation is a mandatory ongoing compliance burden unique to Japan that Chinese exporters must accommodate in their supply chain agreements. Exporters should ensure JIS C 4034-2-1 test reports are prepared for each motor model and made available to their Japanese importer for ANRE annual submissions. This requirement has no counterpart in Chinese domestic motor regulations. Agency for Natural Resources and Energy (ANRE), METI Japan2026-06-12 · unverified
Motor safety and performance — JIS C 4034 series (IEC 60034 adoption) China's GB 755-2019 (旋转电机 额定值和性能) is the national standard for rotating machine ratings and performance, closely aligned with IEC 60034-1 (and therefore with JIS C 4034-1). GB/T 4942-2021 covers IP degrees of protection for rotating machines (aligned with IEC 60034-5). These standards are technically very close to their JIS counterparts. GB 755 is mandatory for domestic sale in China; CCC certification is not currently required for general industrial three-phase motors exported or sold domestically.GB 755-2019 (旋转电机 额定值和性能, equivalent to IEC 60034-1)
GB/T 4942-2021 (旋转电机整体结构的防护等级, aligned with IEC 60034-5)		 In Japan, three-phase induction motors must conform to the JIS C 4034 series for safety and performance. Key parts include JIS C 4034-1 (rating and performance, equivalent to IEC 60034-1), JIS C 4034-5 (IP degrees of protection), and JIS C 4034-6 (cooling methods). JIS C 4034-1 covers rated output, voltage, frequency, duty type, insulation class, temperature rise limits, and performance tolerances. JIS C 4212 specifically covers high-efficiency three-phase cage induction motors and references Top Runner efficiency requirements. JIS standards are published by the Japanese Industrial Standards Committee (JISC) and administered by METI. Conformity to JIS is not itself a market-access licence but is the de facto accepted technical basis for product specification and buyer/procurement requirements in Japan.JIS C 4034-1 (Rotating electrical machines — Rating and performance, equivalent to IEC 60034-1)
JIS C 4034-5 (Degrees of protection — IP code, equivalent to IEC 60034-5)
JIS C 4034-6 (Methods of cooling — IC code, equivalent to IEC 60034-6)
JIS C 4212 (High-efficiency three-phase cage induction motors)		 The technical content of GB 755-2019 and JIS C 4034-1 is very close, as both derive from IEC 60034-1. Motors built to GB 755 will generally satisfy JIS C 4034-1 performance parameters. Key gaps: (1) JIS compliance is the de facto baseline for Japanese procurement and technical documentation — Chinese motors should be able to demonstrate conformance to JIS C 4034-1 parameters even if tested under GB 755, requiring a cross-reference table or dual-claim test report; (2) Japan operates a 50 Hz mains frequency (60 Hz in western Japan) versus China's 50 Hz — 50 Hz-rated motors should work, but nameplate frequency declaration must be correct; (3) JIS C 4212 (high-efficiency motors) is referenced in Top Runner compliance documentation — exporters should verify their motors can be cross-referenced to JIS C 4212 where relevant; (4) No mandatory third-party product certification scheme (equivalent to EU notified-body or China CCC) exists for industrial motors in Japan — conformity is essentially self-declared against JIS.[INFORMATIONAL] Chinese motors built to GB 755-2019 and GB/T 4942-2021 are technically very close to JIS C 4034-1 and JIS C 4034-5 requirements. There is no mandatory third-party safety certification for bare industrial three-phase motors in Japan. The practical gap is documentation: Japanese buyers and procurement specifications typically reference JIS, so exporters should prepare cross-reference documentation showing JIS C 4034-1 parameter equivalence and declare compliance with JIS C 4212 where applicable for high-efficiency motors used in Top Runner compliance claims.
