| Compliance item | Common China baseline | Thailand (TISI / EGAT / MEA) | Gap / action | Source + verification date |
|---|---|---|---|---|
| Motor Efficiency Classes (IE Code) — TIS 2783 Scope | China uses GB 18613-2020 (Energy Efficiency Limits and Energy Efficiency Grades of Motors), which mandates IE3 as the minimum grade (Grade 3) for most three-phase induction motors since 2021-06-01. IE classes in GB 18613-2020 are aligned in naming with IEC 60034-30-1 but have distinct limit values. Motors exported from China are therefore typically IE3 or above, which numerically exceeds the TIS 2783 IE2 floor.GB 18613-2020 (mandatory, IE3 minimum from 2021-06-01) | Thailand's mandatory standard TIS 2783 (issued by the Thai Industrial Standards Institute, TISI) applies to three-phase induction motors in the range 0.75–375 kW and mandates a minimum IE2 (High Efficiency) rating, aligned with IEC 60034-30-1. Motors in scope must undergo TISI product certification (mod-1 or mod-5 scheme) before being placed on the Thai market. The Energy Policy and Planning Office (EPPO) drives the broader IE efficiency programme; EGAT and MEA enforce grid-side connection requirements for connected equipment.TIS 2783 (Thai Industrial Standard for three-phase induction motors, IE2 minimum) IEC 60034-30-1 (IE efficiency class definitions, reference basis for TIS 2783) |
China's mandatory minimum (IE3) is one class above Thailand's mandatory minimum (IE2), so Chinese motors typically exceed the TIS 2783 efficiency floor. However, exceeding the efficiency level does not remove the mandatory TISI product certification requirement. A motor must hold a valid TISI certification under TIS 2783 before it can be imported and sold in Thailand, regardless of its GB 18613 certification status.[INFORMATIONAL] A Chinese motor with GB 18613-2020 IE3 certification likely meets the TIS 2783 IE2 efficiency floor numerically, but cannot be legally placed on the Thai market without a valid TISI product certification. Exporters must apply for TISI mod-1 or mod-5 scheme certification independently. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| TISI Certification Scheme — Mod-1 vs Mod-5 | China's CCC (China Compulsory Certification) covers some low-voltage motors under 1 kV in applicable product scope, administered by CNCA/CQC. CCC uses factory inspection (initial audit + annual surveillance) broadly analogous to TISI Mod-1. Additionally, GB 12665 covers motor cooling and GB 18613-2020 covers efficiency. CCC certification from China is not recognised by TISI and does not substitute for Thai product certification.CCC (China Compulsory Certification, for motors in scope) GB 12665 (motor cooling) GB 18613-2020 |
TISI administers product certification under two primary schemes for motors covered by TIS 2783. Mod-1 (Type Approval) requires factory inspection and ongoing surveillance; it is commonly used by manufacturers with production facilities. Mod-5 (Batch Testing / Lot Certification) applies per-shipment testing and is typically used for importers who lack a certified production site in Thailand. Both schemes require testing at a TISI-accredited laboratory. The certificate must be displayed or documented at point of import.TIS 2783 TISI Certification Scheme Mod-1 (Type Approval) TISI Certification Scheme Mod-5 (Batch / Lot Certification) |
Chinese CCC certification is not mutually recognised by TISI. A motor with CCC certification must still undergo the applicable TISI scheme (Mod-1 for manufacturer-based or Mod-5 for import-batch basis). Mod-5 per-shipment testing adds cost and lead time for each import batch; Mod-1 requires establishing factory-level compliance infrastructure.[INFORMATIONAL] Neither GB 18613-2020 certification nor CCC certification substitutes for TISI product certification under TIS 2783. Chinese exporters must select the appropriate TISI scheme (Mod-1 or Mod-5) and complete testing at a TISI-accredited laboratory before shipment to Thailand. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| Minimum Energy Performance Standard (MEPS) — IE2 under TIS 2783 | GB 18613-2020 mandates IE3 (Grade 3) as the minimum efficiency for most three-phase induction motors since 2021-06-01, which is one class above Thailand's IE2 mandatory minimum. Grade 2 (= IE4) is the voluntary energy-saving evaluation level in China. Motors exported from China that comply with GB 18613-2020 will therefore typically meet or exceed the TIS 2783 efficiency threshold on a numerical basis.GB 18613-2020 (Grade 3 = IE3 mandatory minimum from 2021-06-01) | TIS 2783 establishes IE2 (High Efficiency) as the mandatory minimum efficiency class for three-phase induction motors in the 0.75–375 kW range sold in Thailand. The standard is aligned with IEC 60034-30-1 efficiency class definitions. IE3 is encouraged by EPPO as the voluntary energy-saving target. TISI product certification is the enforcement mechanism; non-certified motors may not be imported or sold.TIS 2783 (IE2 minimum efficiency, 0.75–375 kW three-phase induction motors) IEC 60034-30-1 (IE class definitions, reference basis) |
Thailand's mandatory minimum (IE2) is below China's mandatory minimum (IE3), so Chinese motors already satisfy the efficiency floor in principle. The operative gap is procedural: Thai law requires TISI certification to prove compliance with TIS 2783, and GB 18613-2020 or CCC documentation does not substitute for that certificate. Exporters must secure TISI certification even when the motor's efficiency clearly exceeds TIS 2783 requirements.[INFORMATIONAL] Chinese motors meeting GB 18613-2020 IE3 are likely to satisfy TIS 2783 IE2 efficiency values, but this does not remove the obligation to obtain TISI certification before importing into Thailand. Exporters should confirm efficiency values against TIS 2783 test requirements at a TISI-accredited laboratory. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| IE3 Encouraged Level — EPPO Energy Efficiency Policy | China's GB 18613-2020 Grade 2 (= IE4) is the voluntary energy-saving evaluation level (节能评价值), used as the benchmark for China Energy Label (CEL) certification and government procurement preferences. Chinese factories frequently manufacture to IE3 (Grade 3) as the legal floor, with IE4 (Grade 2) for premium or export lines. Motors at IE3 or above align with EPPO's IE3 encouragement policy.GB 18613-2020 (Grade 2 = IE4, voluntary energy-saving evaluation level) China Energy Label (CEL) scheme |
Thailand's Energy Policy and Planning Office (EPPO) under the Ministry of Energy promotes IE3 and above as the voluntary target efficiency level for industrial motors, in support of Thailand's energy efficiency goals. IE3 is not yet a mandatory legal minimum under TIS 2783 as of the last verified date, but EPPO programmes may incentivise IE3 adoption through energy audits, utility rebates, or procurement preferences for government and large-industry buyers connected to EGAT or MEA grids.EPPO (Energy Policy and Planning Office) energy efficiency promotion programme TIS 2783 (IE2 mandatory floor; IE3 voluntary target) |
No binding gap exists for efficiency level since Chinese motors are at least IE3 and EPPO's IE3 target is voluntary. The practical consideration is market preference: EGAT- or MEA-connected industrial buyers may specify IE3 or IE4 in tender documents, procurement specs, or energy audit recommendations. Chinese exporters should be prepared to demonstrate IE3 or higher if targeting Thai industrial or utility procurement channels.[INFORMATIONAL] Chinese motors at IE3 or above satisfy EPPO's voluntary IE3 encouragement policy and comfortably clear the TIS 2783 IE2 mandatory floor. For procurement into EGAT- or MEA-connected projects, buyers may specify IE3 or IE4 in contracts; exporters should confirm the applicable specification with the Thai buyer. This is informational only and does not constitute legal advice. | Energy Policy and Planning Office (EPPO), Thailand Ministry of Energy2026-06-17 · reference |
| Efficiency Measurement and Test Method — TIS 2783 vs GB/T 1032 | China uses GB/T 1032-2012 as the primary efficiency test standard for three-phase induction motors, referenced by GB 18613-2020. GB/T 1032 is substantially harmonised with IEC 60034-2-1 but allows assumed stray-load losses in some methods, whereas IEC 60034-2-1 requires measured values in key methods. Chinese test reports issued under GB/T 1032 may not be directly accepted by a TISI-accredited laboratory as a substitute for IEC 60034-2-1 testing without equivalence justification.GB/T 1032-2012 (three-phase induction motor test methods) GB 18613-2020 (references GB/T 1032) |
TIS 2783 references IEC 60034-2-1 or equivalent test methods for determining motor efficiency as part of TISI certification testing. Testing must be conducted at a TISI-accredited laboratory. The standard does not accept efficiency declarations based solely on manufacturer datasheets; measured test data from an accredited facility is required to support the TISI certification application under either Mod-1 or Mod-5.TIS 2783 (references IEC 60034-2-1 for test method) IEC 60034-2-1 (loss and efficiency determination) |
Exporters relying solely on GB/T 1032-based test reports may need to conduct additional IEC 60034-2-1 compliant testing at a TISI-accredited laboratory, as TISI certification requires test data from an accredited facility meeting the standard's test method requirements. Stray-load loss treatment differences between GB/T 1032 and IEC 60034-2-1 can result in divergent efficiency figures; this gap is narrower for Thai market access than for EU access because TIS 2783 mandates only IE2 while EU requires IE3/IE4.[INFORMATIONAL] Chinese test reports under GB/T 1032 may need supplementary IEC 60034-2-1 compliant testing at a TISI-accredited laboratory for TISI certification purposes. Given that TIS 2783 requires only IE2 and Chinese motors are typically IE3, the efficiency margin is large enough that stray-load-loss differences are unlikely to cause a pass/fail reversal, but formal TISI-accredited testing remains mandatory. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| EMC Requirements — TIS/IEC 60034 Reference and TISI Scope | China addresses EMC for industrial motors through GB/T 25442 (EMC requirements and test methods for rotating electrical machines) and GB 4343 series (for equipment generating electromagnetic disturbances). CCC scope for motors primarily addresses safety; EMC testing may be required separately depending on the motor's drive electronics or control integration. Chinese export documentation typically includes EMC test reports under IEC or GB standards.GB/T 25442 (EMC requirements for rotating electrical machines) GB 4343 series (electromagnetic disturbance limits for equipment) |
Thailand does not operate an EU-style mandatory standalone EMC directive for industrial motors. EMC requirements for motors in Thailand are addressed primarily through IEC 60034 series provisions referenced in or harmonised with TIS standards. Industrial AC motors operating on EGAT or MEA grids must comply with applicable grid-side interference requirements. NRCT (National Research Council of Thailand) has jurisdiction over radio-frequency emissions where applicable, but industrial motors typically fall outside the primary radio-equipment scope. Purchasers and system integrators connecting motors to EGAT or MEA grids should confirm EMC compatibility with the relevant grid operator requirements.IEC 60034 series (motor EMC provisions, referenced by TIS) EGAT / MEA grid connection requirements (EMC/interference aspects) NRCT (radio frequency emissions, where applicable) |
Thailand does not impose a standalone mandatory EMC certification analogous to the EU's CE EMC Directive for industrial motors, reducing the certification burden compared to EU export. However, motors connected to EGAT or MEA grids may need to demonstrate electromagnetic compatibility under the respective grid operator's technical requirements. Exporters should verify EMC requirements with the Thai importer and end-customer, particularly for variable-speed-drive applications that generate additional harmonic emissions.[INFORMATIONAL] Thailand does not require a standalone EMC certificate for industrial motors equivalent to the EU CE EMC marking. Motors with IEC 60034-compliant EMC characteristics and Chinese GB/T 25442 test reports are broadly acceptable for TIS 2783 certification purposes, but exporters should confirm EMC requirements with the Thai buyer and grid operator for specific installation contexts. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| NRCT Radio Frequency Emissions — Applicability to Motors | China's SRRC (State Radio Regulation of China) type approval is required for radio transmission modules before sale in China. Motors with integrated wireless modules for IoT or remote monitoring would require SRRC approval in China and NBTC approval in Thailand. Standard three-phase induction motors without wireless components are outside the SRRC and NBTC radio-approval scope in both jurisdictions.SRRC (State Radio Regulation of China) type approval (for radio modules) MIIT radio equipment regulations |
The National Research Council of Thailand (NRCT) regulates radio frequency emissions under Thailand's Telecommunications Act and related NBTC (National Broadcasting and Telecommunications Commission) regulations. For standard industrial AC motors without integral radio transmitters or wireless communication modules, NRCT/NBTC radio type approval is generally not required. However, if a motor is supplied with integrated variable-frequency drives (VFDs) or wireless control modules, radio type approval via NBTC may be required for the communication component. Exporters should confirm the scope of any radio module included in the motor package.NBTC (National Broadcasting and Telecommunications Commission) radio type approval Thailand Telecommunications Act (radio frequency regulation) |
For standard three-phase induction motors without wireless modules, no NBTC radio approval gap exists. For motors supplied with integrated VFDs with wireless connectivity or IoT features, both SRRC (China) and NBTC (Thailand) approvals are needed; Chinese SRRC approval does not substitute for Thai NBTC approval. Exporters should clearly separate the motor certification (TISI TIS 2783) from any wireless-component approval pathway.[INFORMATIONAL] Standard industrial AC motors without wireless modules do not require NBTC radio approval for Thailand market entry. If the motor package includes any integrated wireless communication device, a separate NBTC type approval process must be completed; Chinese SRRC approval is not mutually recognised. Confirm the exact configuration with the Thai importer before shipment. This is informational only and does not constitute legal advice. | National Broadcasting and Telecommunications Commission (NBTC), Thailand2026-06-17 · reference |
| Import and Market Placement — TISI Mandatory Product Certification | China's CCC system requires mandatory certification for motors in the CCC product scope administered by CNCA before they may be manufactured for domestic sale or imported. GB 18613-2020 and CCC apply to domestic market placement. For export to Thailand, neither GB 18613-2020 nor CCC certification satisfies TISI requirements; a separate TISI application is required.CCC (China Compulsory Certification, CNCA) GB 18613-2020 |
Motors within the scope of TIS 2783 must hold a valid TISI product certification before they may be imported into or sold within Thailand. TISI operates a mandatory product certification system for listed products; motors in the 0.75–375 kW three-phase induction motor category are among the controlled items. At import, Thai Customs may require presentation of the TISI certificate. Non-compliant motors found in the market may be seized and the importer/distributor may face sanctions under the Industrial Product Standards Act (IPSA).TIS 2783 (mandatory product standard for three-phase induction motors) Industrial Product Standards Act (IPSA), Thailand TISI mandatory certification system for controlled products |
No mutual recognition agreement (MRA) exists between TISI and CNCA/CCC that would allow Chinese CCC certification to substitute for TISI certification for motors. Exporters must initiate a separate TISI application under Mod-1 or Mod-5, including testing at a TISI-accredited laboratory. Lead time for TISI certification can be several months; exporters should plan certification timelines accordingly before committing to Thai supply contracts.[INFORMATIONAL] TISI mandatory product certification under TIS 2783 is the primary market-access barrier for Chinese motors entering Thailand. Chinese CCC and GB 18613-2020 certifications are not recognised by TISI. Exporters should engage a Thai agent or accredited testing laboratory early in the export planning process to determine the appropriate certification scheme (Mod-1 or Mod-5) and realistic timelines. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| Grid Connection — EGAT and MEA Voltage and Frequency Standards | China's standard grid voltage for three-phase industrial supply is 380 V (line-to-line), 50 Hz — the same nominal voltage and frequency as Thailand. Chinese three-phase motors rated at 380 V / 50 Hz are therefore electrically compatible with the Thai EGAT/MEA grid without voltage conversion. GB/T 755 covers motor nameplate ratings including voltage and frequency. This is one of the fewer friction points for Chinese motors entering Thailand compared to 60 Hz markets.GB/T 755 (rotating electrical machines — ratings and performance) GB/T 12668.3 (low-voltage AC drives, including voltage and frequency scope) |
Thailand's electricity grid operates at 380/220 V (three-phase / single-phase), 50 Hz. EGAT (Electricity Generating Authority of Thailand) is the national generation and high-voltage transmission authority; MEA (Metropolitan Electricity Authority) distributes power in Bangkok and surrounding areas. Motors connected to EGAT or MEA grid supply must be rated for 380 V (three-phase, line-to-line), 50 Hz. Grid quality standards and connection requirements are administered by EGAT and MEA respectively; large industrial consumers may also face power factor and harmonic distortion requirements.EGAT grid connection technical requirements MEA distribution grid standards IEC 60034-1 (motor voltage and frequency ratings) |
No voltage or frequency gap exists between standard Chinese three-phase motors (380 V / 50 Hz) and the Thai grid (380 V / 50 Hz). This reduces one common export adaptation cost. Exporters should confirm actual motor nameplate ratings match Thai grid specifications and check power factor and harmonic requirements with EGAT or MEA for large industrial installations.[INFORMATIONAL] Standard Chinese three-phase motors rated 380 V / 50 Hz are electrically compatible with the Thai EGAT/MEA grid, eliminating voltage adaptation as a compliance gap. TISI product certification (TIS 2783) remains the key mandatory requirement. For large industrial grid connections, verify power factor and harmonic distortion requirements directly with EGAT or MEA. This is informational only and does not constitute legal advice. | Electricity Generating Authority of Thailand (EGAT)2026-06-17 · reference |
| Labelling and Marking Requirements under TIS 2783 | Chinese motor nameplates are governed by GB/T 755 (rotating electrical machines — ratings and performance), which specifies similar nameplate data: rated power, voltage, frequency, current, efficiency grade (per GB 18613-2020), insulation class, IP rating, and speed. CCC-certified motors also carry the CCC mark. Chinese motor nameplates and documentation are in Chinese (Simplified) and may not include the TISI mark or Thai-specific information required by TIS 2783.GB/T 755 (motor nameplate data requirements) GB 18613-2020 (efficiency grade marking) CCC mark (China Compulsory Certification) |
Motors certified under TIS 2783 must display the TISI mark (the Thai industrial standard mark, sometimes called the "มอก." mark) on the motor nameplate or label. The mark confirms conformity with TIS 2783 and is issued as part of the TISI product certification. Additional nameplate information required includes: rated power (kW), voltage (V), frequency (Hz), current (A), efficiency class (IE2 minimum), insulation class, protection degree (IP), and speed (rpm). The TISI mark must not be applied before certification is granted.TIS 2783 (nameplate and marking requirements) TISI certification mark (มอก.) requirements |
Chinese motors must have the TISI certification mark (มอก.) added to the nameplate or label after TISI certification is granted. Chinese-only nameplate data does not satisfy TIS 2783 marking requirements. Exporters will need to arrange nameplate modification or additional labelling to include the TISI mark and ensure all required data fields are present in a format legible in the Thai market context.[INFORMATIONAL] Chinese motors must display the TISI certification mark (มอก.) obtained through the TIS 2783 certification process before being placed on the Thai market. Chinese CCC marks and GB efficiency grade markings do not substitute for the TISI mark. Exporters should coordinate nameplate or label updates with their Thai importer as part of the TISI certification process. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| Electrical Safety — IEC 60034-1 and TIS 2783 Safety Provisions | Chinese industrial motor safety is addressed through GB/T 755 (equivalent to IEC 60034-1 for ratings and performance), GB 4208 (equivalent to IEC 60529 for IP ratings), and CCC certification which covers basic electrical safety for motors in scope. GB/T 22719 addresses insulation. Chinese motors manufactured to these GB standards and IEC 60034-1 alignment have safety characteristics broadly compatible with TIS 2783 requirements, but must still pass TISI-accredited safety testing to obtain certification.GB/T 755 (rating and performance, aligned with IEC 60034-1) GB 4208 (IP rating, aligned with IEC 60529) CCC (China Compulsory Certification, safety scope) GB/T 22719 (insulation systems) |
TIS 2783 incorporates safety requirements aligned with IEC 60034-1 (rotating electrical machines — rating and performance) and IEC 60034-5 (degrees of protection, IP rating). Motors must meet the insulation class, temperature rise limits, protection degree (IP rating), and mechanical construction requirements specified in TIS 2783. Safety testing is included as part of the TISI certification process under both Mod-1 and Mod-5 schemes. Thailand does not have a separate standalone low-voltage directive equivalent to the EU LVD; safety requirements are bundled into the TIS 2783 product standard and TISI certification.TIS 2783 (safety provisions aligned with IEC 60034-1 and IEC 60034-5) IEC 60034-1 (rotating electrical machines — rating and performance) IEC 60034-5 (degrees of protection, IP rating) |
Chinese motor safety standards (GB/T 755, GB 4208) are substantially harmonised with IEC 60034-1 and IEC 60034-5, which are the same IEC bases referenced by TIS 2783. This alignment reduces the technical safety gap compared to markets using divergent frameworks. However, TISI certification still requires independent safety testing at a TISI-accredited laboratory; Chinese CCC test reports or factory test records do not automatically satisfy TISI testing requirements.[INFORMATIONAL] Chinese motors built to IEC 60034-1-aligned GB standards have safety characteristics broadly compatible with TIS 2783 requirements, reducing technical re-engineering risk. However, independent safety testing at a TISI-accredited laboratory is still mandatory for TISI certification; existing Chinese CCC test data cannot substitute. Exporters with IEC 60034-compliant motors should face a lower risk of safety test failure but cannot skip the TISI testing process. This is informational only and does not constitute legal advice. | Thai Industrial Standards Institute (TISI)2026-06-17 · reference |
| Hazardous Location (Ex) Motors — Additional Requirements | China's explosion-proof motor certification is administered by CNEX (China National Ex Certification and Testing Centre) under the CNAES scheme, referencing GB 3836 series (equivalent to IEC 60079 series). Chinese Ex-certified motors carry the national Ex mark and are certified under GB 3836 / IEC 60079 alignment. Chinese CNEX certificates are not automatically recognised by Thailand; IECEx certificates (internationally recognised) or locally accepted Ex certification are typically required for hazardous-location installation in Thailand.GB 3836 series (explosive atmospheres, equivalent to IEC 60079 series) CNEX (China National Ex Certification and Testing Centre) CNAES scheme (China national Ex certification) |
Motors intended for use in hazardous locations (explosive atmospheres) in Thailand must comply with IEC 60079 series requirements for explosion protection, in addition to TIS 2783 for general motor requirements. Thailand's Department of Industrial Works (DIW) and relevant fire/safety authorities regulate hazardous location equipment. Ex-certified motors (e.g., Ex d, Ex e, Ex n, Ex p) require certification from an accredited Ex certification body (IECEX scheme or national equivalent). TISI TIS 2783 certification alone does not cover hazardous-location use.IEC 60079 series (explosive atmospheres, Ex equipment) IECEx certification scheme Thailand Department of Industrial Works (DIW) hazardous location regulations |
For standard industrial AC motors not intended for hazardous locations, no Ex certification gap exists. For Ex motors destined for hazardous locations in Thailand, Chinese CNEX certificates are not sufficient; IECEx certificates or Thai-accepted Ex certification are required. Exporters selling Ex motors to Thailand should confirm the acceptable Ex certification scheme with the Thai buyer and DIW before shipment.[INFORMATIONAL] For standard (non-Ex) industrial motors, no additional hazardous-location certification is required beyond TIS 2783. For Ex motors, Chinese CNEX certification is not recognised by Thailand; IECEx certification is the internationally recognised path and is generally accepted. Exporters of Ex motors should verify requirements with DIW and the Thai end-customer before shipment.
