| Compliance item | Common China baseline | Vietnam (TCVN / QCVN / MOIT) | Gap / action | Source + verification date |
|---|---|---|---|---|
| Motor Efficiency Classes (IE Code) under TCVN / QCVN | China uses GB 18613-2020 (Energy Efficiency Limits and Energy Efficiency Grades of Motors) which defines IE1–IE4 grades aligned in naming with IEC 60034-30-1:2014 (Ed.1) but with distinct limit values. GB 18613-2020 mandates IE3 (Grade 3) as the minimum for most three-phase induction motors from 2021-06-01, exceeding Vietnam's IE2 mandatory floor. Motors must carry GB 18613-compliant efficiency markings on their nameplate. CCC certification applies to motors under 1 kV within CCC scope.GB 18613-2020 GB 12665 (cooling and thermal requirements) CCC (China Compulsory Certification, for motors <1 kV in scope) |
Vietnam adopts TCVN standards that align with IEC 60034 for industrial electric motors. QCVN 04:2009/BCT (National Technical Regulation on Energy Efficiency of Electric Motors) issued by the Ministry of Industry and Trade (MOIT) sets mandatory minimum energy performance standards. IE2 (High Efficiency) is the current mandatory minimum for three-phase induction motors within the regulation's scope. The IE efficiency class system references IEC 60034-30 definitions. Energy labels per MOIT requirements must be affixed to motors before placing them on the Vietnam market.QCVN 04:2009/BCT (National Technical Regulation on Energy Efficiency of Electric Motors) TCVN / IEC 60034-30 (efficiency class definitions) MOIT mandatory energy label requirement |
China's GB 18613-2020 mandates IE3 as a minimum, which in principle exceeds Vietnam's IE2 floor under QCVN 04:2009/BCT. However, a motor bearing only GB 18613-2020 IE3 certification does not automatically satisfy Vietnam's import requirements: a separate Vietnam MOIT energy label certificate and QUATEST test report are required. The underlying efficiency limit values in GB 18613-2020 and IEC 60034-30-1 are not identical at all power/pole combinations, so independent verification against QCVN thresholds is needed. CCC certification is not recognised as a substitute for Vietnam MOIT conformity procedures.[INFORMATIONAL] A motor bearing only GB 18613-2020 IE3 certification is not automatically compliant with Vietnam QCVN 04:2009/BCT. A Vietnam MOIT energy label certificate and QUATEST conformity test report are required for import.

| IE3 Policy Direction and Future MEPS Upgrade | China's GB 18613-2020 already mandates IE3 (Grade 3) as the minimum for most three-phase induction motors since June 2021, placing Chinese motors above Vietnam's current IE2 floor. Grade 2 (IE4) is the voluntary energy-saving evaluation level. China's mandatory IE3 baseline provides a strategic export advantage for the Vietnam market if Vietnam-specific energy label and test certification requirements are met.GB 18613-2020 (IE3 mandatory minimum from 2021-06-01) | Vietnam's energy efficiency policy direction under MOIT indicates a trajectory toward IE3 as the mandatory minimum, consistent with Vietnam's energy efficiency improvement programmes and alignment with regional ASEAN trends. While QCVN 04:2009/BCT currently mandates IE2, exporters targeting Vietnam should be aware that a future MEPS upgrade to IE3 is under policy discussion. Importers should monitor MOIT and STAMEQ announcements for regulatory updates. IE3-class motors from China (GB 18613-2020 Grade 3) are positioned to meet a future IE3 mandate without product redesign, subject to Vietnam-specific testing.QCVN 04:2009/BCT (current IE2 mandate) MOIT energy efficiency policy programmes STAMEQ (Vietnam Standards and Quality Institute) — standards body |
The current Vietnam mandatory floor (IE2) is lower than China's mandatory minimum (IE3), so Chinese motors meeting GB 18613-2020 exceed the current Vietnam MEPS in efficiency class terms. However, this does not eliminate the need for Vietnam-specific certification: MOIT energy label and QUATEST test report are still required. The potential future upgrade of Vietnam MEPS to IE3 would eliminate the nominal gap but would not change the testing and labelling procedural requirements.[INFORMATIONAL] Chinese IE3 motors exceed Vietnam's current IE2 mandatory floor but must still obtain Vietnam MOIT energy label certification and QUATEST test reports. Exporters should monitor MOIT for any upgrade of QCVN 04:2009/BCT MEPS to IE3. This is informational only and does not constitute legal advice. | Ministry of Industry and Trade (MOIT), Vietnam2026-06-17 · reference |
| Minimum Energy Performance Standard (MEPS) — IE2 mandatory threshold under QCVN 04:2009/BCT | China's mandatory national standard GB 18613-2020 (effective 2021-06-01) requires IE3 (Grade 3) as the legal minimum for most three-phase induction motors, which exceeds Vietnam's current IE2 mandatory floor. Both China and Vietnam operate on 380/220 V, 50 Hz three-phase grids, so there is no voltage or frequency mismatch for standard motor specifications. Chinese motors meeting GB 18613-2020 Grade 3 (IE3) exceed Vietnam's current MEPS requirement by one efficiency class.GB 18613-2020 (IE3 mandatory minimum from 2021-06-01) | QCVN 04:2009/BCT (National Technical Regulation on Energy Efficiency of Electric Motors), issued by Vietnam's Ministry of Industry and Trade (MOIT), mandates IE2 (High Efficiency) as the minimum energy efficiency class for three-phase AC induction motors in scope (typically 0.75–375 kW, 50 Hz). Motors must carry an MOIT-issued energy label. Conformity testing must be conducted by QUATEST (Quality Assurance and Testing Centre) or another STAMEQ-accredited laboratory. A declaration of conformity and energy label certificate are required for import.QCVN 04:2009/BCT (Vietnam National Technical Regulation on Energy Efficiency of Electric Motors) TCVN / IEC 60034-30 (IE efficiency class definitions) MOIT mandatory energy label programme |
Vietnam mandates IE2 while China mandates IE3; Chinese motors exceed Vietnam's efficiency floor. However, Chinese certification (GB 18613-2020, CCC) is not recognised in Vietnam for market access. Motors must be separately tested by QUATEST or a STAMEQ-accredited lab against QCVN 04:2009/BCT, and an MOIT energy label must be obtained. The 50 Hz grid alignment eliminates voltage/frequency adaptation gaps.[INFORMATIONAL] Chinese motors meeting GB 18613-2020 IE3 exceed Vietnam's current IE2 mandatory floor, but separate QUATEST testing and MOIT energy label certification are required for Vietnam import. Chinese domestic certification is not a substitute for Vietnam conformity procedures. This is informational only and does not constitute legal advice. | Ministry of Industry and Trade (MOIT), Vietnam2026-06-17 · reference |
| Energy Label Certificate — MOIT mandatory energy labelling for import | China has its own mandatory energy efficiency label (能效标识) administered by SAMR under the Energy Efficiency Label Management Regulations. Motors covered by GB 18613-2020 must carry the China energy efficiency label. However, China's domestic energy label is not accepted by Vietnam MOIT as a substitute for Vietnam's mandatory energy label. Both are market-specific labels requiring separate applications and are not mutually recognised.China Energy Efficiency Label Management Regulations (能效标识管理办法) GB 18613-2020 |
Vietnam requires mandatory energy labels (nhan hieu tiet kiem nang luong) for electric motors under MOIT Circular 36/2016/TT-BCT and subsequent amendments, implementing the Law on Economical and Efficient Use of Energy. Motors in scope of QCVN 04:2009/BCT must carry an MOIT energy label before import and market placement. The energy label must be obtained from MOIT or its designated body; application typically requires submission of QUATEST (or accredited lab) test results demonstrating the motor's IE efficiency class. The label discloses the efficiency class and is affixed to the motor nameplate area.MOIT Circular 36/2016/TT-BCT on mandatory energy labelling Law on Economical and Efficient Use of Energy (Vietnam) QCVN 04:2009/BCT |
China's domestic energy efficiency label (能效标识) is not recognised in Vietnam. A separate Vietnam MOIT energy label must be obtained for each motor model/range, supported by QUATEST or accredited-lab test results. This is a procedural and cost gap even where the motor's efficiency performance exceeds Vietnam's IE2 floor. Importers must budget for Vietnam-specific testing and labelling lead time before shipment.[INFORMATIONAL] China's domestic energy label is not a substitute for Vietnam MOIT energy label. Exporters must obtain a separate Vietnam energy label through QUATEST testing for each motor model before shipment. This is informational only and does not constitute legal advice. | Ministry of Industry and Trade (MOIT), Vietnam2026-06-17 · reference |
| QUATEST Conformity Testing and Declaration of Conformity | China's conformity system for motors involves CCC (China Compulsory Certification) administered by CNCA for motors within CCC scope (<1 kV, within the CCC catalogue), and GB 18613-2020 compliance enforcement by SAMR. CCC certification involves testing by a CNCA-designated lab and factory audit. Neither CCC nor SAMR enforcement actions are recognised by Vietnam authorities as substitutes for QUATEST conformity testing under QCVN 04:2009/BCT.CCC (China Compulsory Certification, CNCA) GB 18613-2020 (SAMR enforcement) |
Motors imported into Vietnam under QCVN 04:2009/BCT must undergo conformity testing at QUATEST (Quality Assurance and Testing Centre under STAMEQ/Ministry of Science and Technology) or another STAMEQ-accredited laboratory. The importer must submit a declaration of conformity (cong bo hop quy) to MOIT or the relevant authority, together with the QUATEST test report and energy label certificate, before customs clearance. QUATEST has three regional centres (Ho Chi Minh City, Hanoi, Da Nang). Testing fees and lead times apply per motor series.QCVN 04:2009/BCT STAMEQ accreditation framework QUATEST (Quality Assurance and Testing Centre 1/2/3) |
Chinese CCC certification and GB 18613-2020 compliance records are not accepted in Vietnam as substitutes for QUATEST conformity testing under QCVN 04:2009/BCT. Separate QUATEST testing, declaration of conformity submission to MOIT, and energy label application are all required for Vietnam import. This creates additional lead time (typically weeks) and cost for each motor model exported to Vietnam.[INFORMATIONAL] Chinese CCC and GB 18613-2020 certifications do not substitute for Vietnam QUATEST conformity testing and MOIT declaration of conformity. Exporters must engage QUATEST or a STAMEQ-accredited lab for each motor model series before Vietnam customs clearance.

| EMC / Radio Frequency — VNPT and MOIT requirements for wireless-capable equipment | In China, EMC requirements for industrial motors are covered under GB/T 10069 series (measurement of airborne noise) and general EMC standards GB/T 17626 series. Motors with integrated inverters or VSD are subject to additional EMC requirements under GB/T 12668 (adjustable-speed drive systems). CCC certification for motors within scope includes electromagnetic disturbance testing per relevant GB standards. China's CCC EMC test results are not directly recognised by Vietnam's MIC or MOIT for market access purposes.GB/T 17626 series (EMC immunity/emission for industrial equipment) GB/T 12668 (adjustable-speed drive systems EMC) CCC EMC testing scope |
Vietnam's electromagnetic compatibility (EMC) and radio frequency (RF) requirements for industrial equipment are administered by VNPT (Vietnam Posts and Telecommunications Group) and overseen by the Ministry of Information and Communications (MIC) for wireless/radio aspects, and by MOIT for energy-related equipment. Standard industrial three-phase induction motors without integrated wireless or variable-speed drive electronics are not typically subject to Vietnam RF/wireless type approval. However, if a motor incorporates a variable speed drive (VSD), inverter, or wireless monitoring module, the integrated product may require conformity assessment under Vietnam's telecommunications regulatory framework. EMC baseline is aligned with TCVN/IEC standards.TCVN / IEC 60034 series (motor EMC baseline) Vietnam Telecommunications Law (wireless/radio aspects, MIC) VNPT type approval framework for radio equipment |
Standard three-phase induction motors without integrated wireless or drive electronics face minimal Vietnam-specific EMC procedural requirements beyond the QCVN 04:2009/BCT energy efficiency compliance path. The main gap arises for motors with integrated VSDs or wireless modules: these require Vietnam MIC/VNPT type approval in addition to MOIT energy label compliance. Chinese CCC EMC documentation is not accepted as a substitute. Exporters should verify whether their motor configuration includes any wireless or active power-electronics components that would trigger Vietnam RF type approval.[INFORMATIONAL] Standard three-phase induction motors without wireless or inverter integration face minimal Vietnam EMC procedural barriers beyond the QCVN 04:2009/BCT energy path. Motors with integrated VSDs or wireless modules require separate Vietnam MIC/VNPT type approval; Chinese CCC EMC documentation is not a substitute. Verify motor configuration before export.

| Electrical Safety — TCVN / IEC 60034 insulation and low-voltage safety for grid connection | Chinese industrial motors are manufactured to GB/T 755 (Rating and Performance of Rotating Electrical Machines, aligned with IEC 60034-1) and GB 12665 (Motor Cooling Requirements). The 380/220 V, 50 Hz grid specification is identical between China and Vietnam, so motors designed for the Chinese market are electrically compatible with the Vietnam grid without modification. CCC certification for low-voltage motors covers basic electrical safety including insulation and temperature rise per the relevant GB/T standards.GB/T 755 (aligned with IEC 60034-1) GB 12665 (motor cooling) CCC (electrical safety testing scope) |
Vietnam's electrical safety requirements for industrial motors align with TCVN standards adopting IEC 60034 series (rotating electrical machines). The Vietnam grid for three-phase motors is 380/220 V, 50 Hz — identical to China's standard three-phase supply, eliminating voltage/frequency adaptation requirements. Insulation class, temperature rise, and protection degree (IP rating) requirements follow IEC 60034 as adopted by TCVN. MOIT and the Vietnam Electricity Regulatory Authority (ERAV) oversee electrical safety in the energy sector. No separate Vietnam low-voltage directive equivalent to the EU LVD currently applies; the QCVN 04:2009/BCT energy efficiency conformity path covers the main regulatory gate for motor imports.TCVN / IEC 60034 series (rotating electrical machines — insulation, temperature rise, IP rating) QCVN 04:2009/BCT (main regulatory gate for motor imports) ERAV (Electricity Regulatory Authority of Vietnam) |
Vietnam's 380/220 V, 50 Hz three-phase grid is identical to China's, so no voltage or frequency modification is required for standard Chinese motors exported to Vietnam. The electrical safety technical gap is minimal because both countries' standards align with IEC 60034 series via TCVN and GB/T 755 respectively. The procedural gap is that Chinese CCC electrical safety documentation is not accepted by Vietnam; QUATEST testing under QCVN 04:2009/BCT covers the main conformity gate and implicitly addresses safety performance.[INFORMATIONAL] Chinese motors designed for 380/220 V, 50 Hz are electrically compatible with the Vietnam grid without modification. The electrical safety technical gap is minimal given shared IEC 60034 alignment, but Chinese CCC documentation does not substitute for Vietnam QUATEST testing under QCVN 04:2009/BCT. This is informational only and does not constitute legal advice. | Electricity Regulatory Authority of Vietnam (ERAV)2026-06-17 · reference |
| Import Declaration and Customs — Declaration of Conformity and Energy Certificate for Vietnam Customs | China's export documentation for industrial motors typically includes a CCC certificate, GB 18613-2020 compliance evidence, factory test reports, and standard commercial export documents (commercial invoice, packing list, certificate of origin). For motors exported to Vietnam under China-ASEAN FTA (ACFTA), a Form E certificate of origin may reduce import tariff rates. Chinese export documents must be supplemented by Vietnam-specific conformity documentation; they do not replace MOIT and QUATEST requirements.CCC (China Compulsory Certification export documentation) China-ASEAN FTA (ACFTA) Form E certificate of origin GB 18613-2020 compliance documentation |
Motors imported into Vietnam under QCVN 04:2009/BCT scope require a declaration of conformity (cong bo hop quy) submitted to MOIT, a QUATEST or STAMEQ-accredited lab test report, and a valid MOIT energy label certificate before customs clearance. Vietnam Customs (General Department of Vietnam Customs, GDVC) may require presentation of the conformity declaration and energy label certificate at the point of import. Importers must ensure all documents are in Vietnamese or accompanied by certified translations. HS code classification determines whether the motor falls under controlled goods lists requiring pre-clearance.QCVN 04:2009/BCT (declaration of conformity requirement) GDVC (General Department of Vietnam Customs) import regulations MOIT energy label certificate requirement |
Chinese export documentation (CCC, GB 18613-2020) does not substitute for Vietnam import requirements. Importers must obtain: (1) QUATEST or STAMEQ-accredited lab test report; (2) MOIT energy label certificate; (3) declaration of conformity filed with MOIT; and (4) ensure customs documents include the energy label reference. Form E origin certificate can reduce ACFTA tariff rates and should be obtained for cost efficiency. Documentation must be in Vietnamese or with certified translation.[INFORMATIONAL] Chinese motor exporters must obtain Vietnam-specific MOIT energy label, QUATEST test report, and declaration of conformity before shipment. Consider Form E (ACFTA) for tariff reduction. Chinese CCC documentation does not substitute for Vietnam import requirements. This is informational only and does not constitute legal advice. | General Department of Vietnam Customs (GDVC)2026-06-17 · reference |
| Tariff and Trade — China-ASEAN FTA (ACFTA) preferential duty and import duty rates | Chinese motor manufacturers exporting to Vietnam can benefit from ACFTA preferential duty rates by obtaining a Form E certificate of origin (issued by China Customs or CCPIT). The Form E declares that the motor meets ACFTA rules of origin (typically regional value content and HS tariff change criteria). Motors must be shipped directly from China or transit without modification. ACFTA duty reduction is separate from and in addition to compliance with QCVN 04:2009/BCT energy efficiency requirements.ACFTA Form E (certificate of origin, issued by China Customs / CCPIT) ACFTA rules of origin (RVC and CTC criteria) |
Vietnam's import duty on industrial electric motors (HS 8501.52 — AC motors, multi-phase, output 750W–75kW; 8501.53 — above 75kW) varies by HS subheading and whether the ACFTA preferential rate applies. Under the China-ASEAN Free Trade Agreement (ACFTA), Chinese-origin motors may qualify for reduced or zero duty with a valid Form E certificate of origin issued by Chinese customs/CCPIT. Standard MFN tariff rates for motors may range from 0–10% depending on the HS code; ACFTA rates can be significantly lower. VAT at 10% applies on import. Importers must confirm current ACFTA rates via Vietnam Customs or MOIT trade databases.China-ASEAN Free Trade Agreement (ACFTA) — Form E certificate of origin Vietnam Customs Tariff Schedule (HS Chapter 85) Vietnam VAT Law (10% import VAT) |
ACFTA preferential rates are available to Chinese motor exporters but require a Form E certificate of origin — this is a procedural step many first-time exporters overlook, defaulting to MFN tariff rates and paying excess duty. The 10% Vietnam VAT on import is non-reducible regardless of ACFTA status. There is no tariff gap in the sense of absolute prohibition; the gap is procedural (Form E application) and cost-related (MFN vs. ACFTA rate differential).[INFORMATIONAL] Chinese motor exporters should apply for Form E (ACFTA) to access preferential import duty rates in Vietnam. Without Form E, MFN tariff rates apply. Import VAT at 10% is mandatory regardless. Actual tariff rates depend on HS subheading and current ACFTA schedules — verify with Vietnam Customs or a licensed customs broker before shipment.

| Market Surveillance and STAMEQ — Ongoing compliance monitoring after import | China's market surveillance for motor energy efficiency is conducted by SAMR (State Administration for Market Regulation) and provincial market regulation bureaux. SAMR conducts periodic spot-checks (飞行检查/监督抽查) on motors in the market to verify GB 18613-2020 compliance. Non-compliant motors may be recalled, fined, or the manufacturer's CCC certificate suspended. China's market surveillance framework is not reciprocated by Vietnam; exporters must manage separate compliance obligations in both jurisdictions.SAMR (State Administration for Market Regulation) — China market surveillance GB 18613-2020 ongoing compliance |
Vietnam's market surveillance for energy-efficient products including motors is conducted by STAMEQ (Vietnam Standards and Quality Institute, under the Ministry of Science and Technology) and MOIT energy efficiency inspectors. Products found to be non-compliant with QCVN 04:2009/BCT after market entry may be subject to recalls, fines, or import bans. Importers and distributors are responsible for ensuring ongoing QCVN compliance throughout the product's market life. STAMEQ periodically samples products from the market and sends them to accredited laboratories for verification testing.STAMEQ (Vietnam Standards and Quality Institute, under MOST) QCVN 04:2009/BCT (ongoing compliance obligation) MOIT energy efficiency inspection authority |
China's market surveillance compliance track record (SAMR) does not carry over to Vietnam. Exporters and Vietnam importers/distributors must maintain their own QCVN 04:2009/BCT conformity records, energy label certificates, and QUATEST test reports to respond to STAMEQ spot-checks. Product changes or new model variants may require new QUATEST testing. The ongoing compliance burden is separate from and in addition to the initial import clearance documentation.[INFORMATIONAL] Vietnam importers and distributors of Chinese motors must maintain QCVN 04:2009/BCT conformity records and energy label certificates for STAMEQ spot-checks after market entry. China SAMR compliance records have no standing in Vietnam. This is informational only and does not constitute legal advice. | STAMEQ (Vietnam Standards and Quality Institute)2026-06-17 · reference |
| Motor Nameplate and Marking Requirements for Vietnam Market | Chinese motors are marked per GB/T 755 and GB 18613-2020 requirements, which require nameplate disclosure of rated voltage, power, speed, efficiency class, insulation class, and IP rating aligned with IEC 60034-1. Chinese-language nameplates are standard for the domestic market. For export to Vietnam, Chinese-only nameplates must be supplemented with Vietnamese-language markings or bilingual labels. The efficiency class marking must be consistent with the MOIT energy label certificate obtained for Vietnam.GB/T 755 (aligned with IEC 60034-1) GB 18613-2020 (efficiency class nameplate requirement) |
Motors placed on the Vietnam market must carry nameplates compliant with TCVN standards (aligned with IEC 60034-1) disclosing: rated voltage (380/220 V, 3-phase, 50 Hz for Vietnam grid), rated power (kW), rated speed (rpm), efficiency class (IE level), insulation class, protection degree (IP rating), and manufacturer details. In addition, the MOIT mandatory energy label (showing the IE efficiency class) must be affixed to the motor. All markings must be legible and durable. Nameplates in Chinese only are not acceptable — Vietnamese-language labelling or bilingual labels including Vietnamese are required for products marketed in Vietnam.TCVN / IEC 60034-1 (nameplate and marking requirements for rotating electrical machines) MOIT mandatory energy label (IE class, affixed to motor) Vietnam consumer labelling regulations |
Chinese domestic nameplates (Chinese language only) are not sufficient for Vietnam market placement. Vietnamese-language labelling or bilingual labels including Vietnamese are required. The efficiency class shown on the nameplate must match the MOIT energy label certificate for the specific motor model. Exporters must plan for relabelling or bilingual nameplate production for Vietnam-destined motors. The MOIT energy label is a separate physical label in addition to the nameplate.[INFORMATIONAL] Chinese domestic nameplates do not satisfy Vietnam labelling requirements. Motors exported to Vietnam require Vietnamese-language or bilingual nameplates, plus the MOIT energy label physically affixed to the motor. Exporters should plan nameplate localisation as part of the Vietnam market entry process.

| Grid Compatibility and Installation Safety — 380/220 V, 50 Hz alignment | China's three-phase industrial grid is 380/220 V, 50 Hz — identical to Vietnam. Standard Chinese three-phase induction motors designed for the China domestic market are rated for 380 V, 50 Hz and are electrically compatible with the Vietnam grid without modification. GB/T 755, GB 12665, and installation standards GB 50055 (Motor Installation Design Specification) govern installation safety in China. IEC 60364 alignment is strong in both countries, minimising installation safety technical divergence.GB/T 755 (IEC 60034-1 aligned — voltage and frequency ratings) GB 50055 (Motor Installation Design Specification) China grid standard: 380/220 V, 50 Hz |
Vietnam's three-phase industrial power grid operates at 380/220 V (line-to-line / line-to-neutral), 50 Hz, which is identical to China's standard three-phase supply. Motors imported for Vietnam must be rated for 380 V (delta) or 380/220 V (star/delta) at 50 Hz. Installation and electrical safety follow Vietnam's National Electrical Code (QCVN 01:2020/BCT on electrical installation safety) and IEC-aligned TCVN standards. Grounding (earthing) and protective conductor requirements follow IEC 60364 as adopted by TCVN. No voltage adaptation or frequency conversion is required for standard Chinese three-phase motors.QCVN 01:2020/BCT (Vietnam National Technical Regulation on Electrical Installation Safety) TCVN / IEC 60364 (electrical installations — earthing, protective conductors) Vietnam grid standard: 380/220 V, 50 Hz |
There is no voltage or frequency technical gap between China and Vietnam for standard three-phase industrial motors. Both grids are 380/220 V, 50 Hz. Chinese motors designed for the domestic market require no electrical modification for Vietnam deployment. The only gap in this area is procedural: installation must comply with Vietnam's QCVN 01:2020/BCT and local electrical codes rather than China's GB 50055, and inspections are conducted by Vietnam authorities, not Chinese ones.[INFORMATIONAL] Standard Chinese three-phase motors rated 380/220 V, 50 Hz are electrically compatible with the Vietnam grid without modification. Installation must comply with Vietnam QCVN 01:2020/BCT electrical safety requirements rather than Chinese standards. There is no voltage or frequency technical barrier for this product category.
