KEMCO Mandatory Energy Efficiency Grade — Grade 1 to Grade 5?

Major gap — KEMCO energy-efficiency grade labelling is a South Korea-specific market requirement; China efficiency data must be reclassified and recalculated.

Korean Performance Testing — SCOP, COP, Capacity, and 60 Hz Supply?

Critical gap — Korean energy and performance evidence must be generated or validated for 60 Hz operation; China 50 Hz heat-pump designs are not directly compatible.

KC Mandatory Certification — ECPSA and KATS Scope?

Major gap — KC certification and Korean safety documentation are required where ECPSA applies; CCC certificates and GB reports do not replace KC.

Refrigerant Registration and HFC Controls — KEC / MOE Fluorine Management Act?

Gap — refrigerant documentation must be mapped to South Korea KEC / MOE controls; GB 9237 and China product labels are not enough by themselves.

Allowed and Phasing-out Refrigerants — R-32, R-410A, and R-22?

Gap — R-32 and R-410A may be usable but still need Korean review, while R-22 phase-out makes legacy designs high risk for new South Korea exports.

Electrical Safety, EMC, and Grid Compatibility — 220 V / 380 V at 60 Hz?

Critical gap — South Korea 60 Hz electrical compatibility and EMC evidence must be validated separately; China 50 Hz heat pumps are not directly compatible.

Top Runner Programme — Heat-pump HVAC SCOP Targets?

Gap — South Korea Top Runner SCOP or target-performance treatment must be checked separately from China efficiency reports and KEMCO grade labelling.

Compliance item	Common China baseline	South Korea (KC / KEMCO / KEC)	Gap / action	Source + verification date
KEMCO Mandatory Energy Efficiency Grade — Grade 1 to Grade 5	China commonly relies on GB 25454 and GB/T 7725 for heat-pump and air-conditioner COP, SCOP, and performance evidence, CCC mandatory certification for applicable heat pumps up to 40 kW, and GB 9237 as a refrigerant safety baseline. China Energy Label values are not automatically mapped to South Korea's KEMCO Grade 1 to Grade 5 label.GB 25454 GB/T 7725 CCC mandatory certification for applicable heat pumps up to 40 kW GB 9237	South Korea requires covered heat-pump and air-conditioning products to comply with the KEMCO energy efficiency labelling framework before market placement. The label uses a Grade 1 to Grade 5 scale, with Grade 1 as the highest grade, and product classification, test data, model registration, and Korean label content must follow Korean rules rather than China label categories.KEMCO energy efficiency labelling and standards programme Energy Use Rationalization Act MOTIE energy efficiency policy	Chinese GB efficiency reports may be useful engineering inputs, but exporters still need Korean classification, Korean test conditions, KEMCO registration data, Korean energy-label artwork, and grade calculation. Grade 1 is the highest grade in South Korea, so claims must not reuse China grade terminology without recalculation.[INFORMATIONAL] Major gap — KEMCO energy-efficiency grade labelling is a South Korea-specific market requirement; China efficiency data must be reclassified and recalculated.

Korean Performance Testing — SCOP, COP, Capacity, and 60 Hz Supply	China commonly relies on GB 25454 and GB/T 7725 for COP, SCOP, capacity, and performance evidence, CCC mandatory certification for applicable heat pumps up to 40 kW, and GB 9237 as a refrigerant safety baseline. China domestic testing typically assumes China-market electrical design conditions and does not prove 60 Hz Korean compatibility.GB 25454 GB/T 7725 CCC mandatory certification for applicable heat pumps up to 40 kW GB 9237	South Korea's energy-efficiency assessment for heat-pump HVAC products must reflect Korean product classes, rated capacities, seasonal performance metrics such as SCOP where applicable, and the Korean power system of 220 V single-phase residential supply or 380 V three-phase commercial supply at 60 Hz. China-market 50 Hz compressor, fan, inverter, and control designs require South Korea-specific validation.KEMCO energy efficiency test and registration rules Korean 220 V / 380 V, 60 Hz supply conditions Applicable KS C IEC heat-pump and air-conditioner standards	The voltage label may look similar for residential products because both China and South Korea use nominal 220 V, but the frequency difference is critical. A China 50 Hz heat pump cannot be treated as directly compatible with South Korea's 60 Hz grid without compressor, motor, inverter, protection, heating performance, noise, and durability validation.[INFORMATIONAL] Critical gap — Korean energy and performance evidence must be generated or validated for 60 Hz operation; China 50 Hz heat-pump designs are not directly compatible.

KC Mandatory Certification — ECPSA and KATS Scope	China commonly relies on GB 25454 and GB/T 7725 for heat-pump and air-conditioner efficiency and performance evidence, CCC mandatory certification for applicable heat pumps up to 40 kW, and GB 9237 as a refrigerant safety baseline. These Chinese documents support domestic compliance but are not recognized as KC certification evidence for South Korea.GB 25454 GB/T 7725 CCC mandatory certification for applicable heat pumps up to 40 kW GB 9237	South Korea requires in-scope electrical appliances and consumer products to obtain KC certification before sale under the Electrical Appliances and Consumer Products Safety Control Act, with KATS overseeing the safety framework. Heat-pump HVAC products must be assessed for KC Mark applicability, Korean model registration, Korean-language markings, factory and importer obligations, and adopted KS C IEC standards such as KS C IEC 60335-2-40 for heat-pump and air-conditioning safety.Electrical Appliances and Consumer Products Safety Control Act (ECPSA) KC Mark mandatory certification KATS safety certification framework KS C IEC 60335-2-40	CCC is not recognized as KC. Chinese exporters must prepare a South Korea-specific KC certification package, confirm KS C IEC 60335-2-40 alignment, identify in-scope components, provide Korean markings and manuals, and support importer or local representative obligations. The finished product also needs 60 Hz compatibility evidence because China-market 50 Hz compressor designs are not directly compatible with South Korea.[INFORMATIONAL] Major gap — KC certification and Korean safety documentation are required where ECPSA applies; CCC certificates and GB reports do not replace KC.

Allowed and Phasing-out Refrigerants — R-32, R-410A, and R-22	China commonly relies on GB 25454 and GB/T 7725 for performance evidence, CCC mandatory certification for applicable heat pumps up to 40 kW, and GB 9237 as a refrigerant safety baseline. A refrigerant allowed or historically used in China does not automatically satisfy South Korea's phase-down, labelling, or safety documentation expectations.GB 25454 GB/T 7725 CCC mandatory certification for applicable heat pumps up to 40 kW GB 9237	For South Korea market planning, R-32 and R-410A remain usable refrigerants for many heat-pump applications subject to applicable safety, registration, labelling, and HFC management controls, while R-22 is being phased out and should not be treated as a normal new-product refrigerant choice. Refrigerant selection also affects KC safety evaluation under KS C IEC 60335-2-40.Fluorine Management Act South Korea HFC phase-down policy KS C IEC 60335-2-40 refrigerant safety provisions KEC / MOE refrigerant controls	Chinese exporters should avoid assuming that an R-22 legacy design can be exported as a normal Korean-market product. R-32 and R-410A designs still need Korean charge-limit, flammability, leakage, marking, service, and recovery review, particularly where the product is redesigned for 60 Hz compressors.[INFORMATIONAL] Gap — R-32 and R-410A may be usable but still need Korean review, while R-22 phase-out makes legacy designs high risk for new South Korea exports.

Electrical Safety, EMC, and Grid Compatibility — 220 V / 380 V at 60 Hz	China commonly relies on GB 25454 and GB/T 7725 for efficiency and performance, CCC mandatory certification for applicable heat pumps up to 40 kW, and GB 9237 as a refrigerant safety baseline. China-market electrical evidence generally reflects 50 Hz product design and does not by itself prove South Korea 60 Hz safety, EMC, compressor, inverter, or control compatibility.GB 25454 GB/T 7725 CCC mandatory certification for applicable heat pumps up to 40 kW GB 9237	South Korea uses 220 V single-phase residential supply and 380 V three-phase commercial supply at 60 Hz. Heat-pump HVAC products must demonstrate electrical safety and grid compatibility for these Korean conditions, and EMC obligations may involve MSIT / KCC rules in addition to KC safety under KATS. KS C IEC standards are adopted for relevant safety testing.KS C IEC 60335-2-40 KC safety requirements under ECPSA MSIT / KCC EMC rules South Korea 220 V / 380 V, 60 Hz grid conditions	This is a critical design gap. Residential nominal voltage is similar to China at 220 V, but South Korea is 60 Hz, so China 50 Hz heat pumps should be treated as incompatible until the compressor, motors, inverter drive, protection devices, thermal performance, EMC, noise, and marking package are validated for Korea.[INFORMATIONAL] Critical gap — South Korea 60 Hz electrical compatibility and EMC evidence must be validated separately; China 50 Hz heat pumps are not directly compatible.
