Electromagnetic Compatibility — Household Refrigerating Appliances (GSO CISPR 14 series under DGSM) China's EMC requirements for household appliances (including refrigerators) are primarily governed by GB 4343.1-2018 (Electromagnetic disturbance characteristics of household appliances, electric tools and similar apparatus — Part 1: Emission limits and measurement methods; mandatory, equivalent to CISPR 14-1:2016) and GB/T 4343.2-2020 (Part 2: Immunity; recommended, equivalent to CISPR 14-2:2015). For harmonic emissions, GB 17625.1-2022 (mandatory, IDT IEC 61000-3-2:2020) applies. These are enforced under the CCC regime administered by SAMR/CNCA. Because both China and Oman adopt the CISPR 14 family, the technical content is closely aligned, but a Chinese GB 4343.1 CCC test report is not by itself accepted as the conformity basis under the Omani DGSM scheme.GB 4343.1-2018 — Electromagnetic disturbance characteristics of household appliances, electric tools and similar apparatus — Part 1: Emission limits and measurement methods (mandatory; equivalent to CISPR 14-1:2016; enforced under CCC by SAMR/CNCA)
GB/T 4343.2-2020 — Part 2: Immunity — product family standard (recommended; equivalent to CISPR 14-2:2015)
GB 17625.1-2022 — Limits for harmonic current emissions up to and including 16 A per phase (mandatory; IDT IEC 61000-3-2:2020)
Household refrigerating appliances placed on the Omani market are expected to meet electromagnetic compatibility requirements based on the GSO adoptions of the CISPR 14 series — GSO CISPR 14-1 (emission requirements for household appliances, electric tools and similar apparatus) and GSO CISPR 14-2 (immunity), which mirror the IEC/CISPR international standards. EMC conformity is assessed within the DGSM conformity scheme administered by MOCIIP. For refrigerators with inverter-driven (variable-speed) compressors, conducted and radiated emission limits and harmonic-current behaviour (CISPR 14-1 / IEC 61000-3-2 family) are the relevant phenomena. Conformity is normally demonstrated via a type-test report (IECEE CB / CISPR basis) accepted by a DGSM-recognised conformity body. Appliances with wireless connectivity must additionally meet TRA radio requirements (see market-access row). Tests should reflect the Omani 240 V, 50 Hz supply, though the 50 Hz frequency matches China.GSO CISPR 14-1 — Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission (GSO adoption of CISPR 14-1)
GSO CISPR 14-2 — Part 2: Immunity — product family standard (GSO adoption of CISPR 14-2)
GSO IEC 61000-3-2 — Limits for harmonic current emissions (input current up to and including 16 A per phase) — supplementary where applicable
DGSM (MOCIIP) conformity scheme — EMC assessment for regulated electrical products
Because GB 4343.1 and the GSO CISPR 14-1 adoption share the same CISPR 14 lineage, the underlying technical gap is small for most refrigerator types. The remaining gaps are procedural: (1) Conformity route — the Omani DGSM scheme requires the EMC evidence to be presented to a DGSM-recognised body; a CNAS-only GB 4343.1 report typically needs to be re-presented or supplemented as an IECEE CB / CISPR-format report. (2) Inverter compressors — variable-speed inverter refrigerators may generate emissions and harmonic behaviour that older GB 4343.1 test configurations did not fully cover; the manufacturer should confirm the existing test data covers inverter-specific operating modes against the CISPR 14-1 edition referenced by GSO. (3) Wireless models — any Wi-Fi/Bluetooth function moves the appliance into TRA radio scope, which CCC EMC data does not address.[INFORMATIONAL] EMC conformity to the GSO CISPR 14 series under the DGSM scheme applies to household refrigerators entering Oman. Chinese GB 4343.1 CCC test data is technically close (shared CISPR 14 lineage) but is not directly accepted as the Omani conformity basis; evidence should be re-presented in IECEE CB / CISPR format to a DGSM-recognised body. Inverter-compressor and wireless models warrant extra verification. GCC Standardization Organization (GSO)2026-06-15 · reference
Minimum Energy Performance Standards (MEPS) — Household Refrigerators (GSO MEPS under DGSM) China's mandatory energy-efficiency standard for household refrigerators is GB 12021.2-2015 (Minimum allowable values of energy efficiency and energy efficiency grades for household refrigerators). It defines energy-efficiency grades (Grade 1 most efficient, Grade 5 minimum threshold) and minimum annual energy-consumption limits. It is mandatory (GB), enforced by SAMR, with the energy-labelling system administered by the NDRC; products must display the China Energy Label (CEL) before sale. The GB 12021.2 calculation basis and grade scale differ from the GSO MEPS/star methodology — a Chinese Grade 1 or Grade 2 rating does not automatically equal compliance with the GSO MEPS floor and must be recalculated to the GSO methodology.GB 12021.2-2015 — Minimum allowable values of energy efficiency and energy efficiency grades for household refrigerators (mandatory; enforced by SAMR/NDRC under China Energy Label system)
GB/T 8059-2016 — Household and similar refrigerating appliances test methods (aligned with IEC 62552 series)
Refrigerators sold in Oman must meet the Gulf (GSO/GCC) minimum energy performance standards (MEPS) for household refrigerating appliances, administered in Oman by DGSM under MOCIIP. The GCC energy-efficiency scheme for refrigerators (GSO refrigerator energy-efficiency standard, commonly cited as GSO 2530 and the related GCC energy-label/MEPS measures) sets a minimum energy-efficiency threshold below which a model may not be registered or placed on the market, and defines the energy-efficiency star rating used on the label. The energy-efficiency index is derived from rated volume, climate category, and the GSO test/calculation methodology (aligned with the IEC 62552 measurement family). A model that does not meet the MEPS floor cannot obtain a DGSM energy registration and therefore cannot be cleared for import. Measurements should reflect the Omani 240 V, 50 Hz supply.GSO 2530 — Energy efficiency labelling and minimum energy performance requirements for household refrigerating appliances (GCC refrigerator energy-efficiency standard; MEPS floor + star rating)
GSO / GCC energy-efficiency label scheme for electrical appliances — administered in Oman by DGSM (MOCIIP)
GSO IEC 62552 (Household refrigerating appliances — characteristics and test methods) — measurement basis for the energy-efficiency index
Two gaps: (1) Methodology and threshold — the GSO MEPS floor and star-rating index use a different reference-consumption formula and climate categorisation than GB 12021.2-2015. A model rated Grade 1/2 in China must have its energy-efficiency index recalculated to the GSO methodology to confirm it clears the GSO MEPS floor; some China-tuned models may fall below the Gulf MEPS threshold and be rejected at registration. (2) Test conditions — GSO testing references the IEC 62552 family at the Omani 240 V, 50 Hz supply and the Gulf climate category (high ambient temperatures), which can materially change measured consumption versus China's 220 V test conditions; existing GB 12021.2 / GB/T 8059 reports usually cannot be reused without re-testing or recalculation at the GSO reference conditions. There is no GSO database registration that mirrors any Chinese export obligation — the energy registration is a fresh Omani/Gulf step.[INFORMATIONAL] The GSO/GCC refrigerator MEPS floor (GSO 2530) is a hard gate for Oman: a model below the threshold cannot obtain DGSM energy registration. Chinese GB 12021.2 grades do not substitute — the energy-efficiency index must be recalculated to the GSO methodology at Gulf test conditions (IEC 62552, 240 V / 50 Hz, high-ambient climate category) before registration.

Energy Label — GCC Energy-Efficiency Label / Star Rating (GSO scheme via DGSM) China's energy labelling for household refrigerators is the China Energy Label (CEL) under the Measures for the Administration of Energy Efficiency Labels (NDRC/SAMR, 2016 revision), displaying a 1-to-5 grade scale (1 highest) and annual energy consumption. Labels are administered by the China National Institute of Standardization (CNIS) under NDRC/SAMR; manufacturers self-declare the grade based on GB 12021.2 testing. The Chinese CEL (1-to-5 grade, Chinese-language) is structurally different from the GCC star-rating label and is not cross-comparable; it cannot serve as the Omani label.Measures for the Administration of Energy Efficiency Labels (NDRC/SAMR 2016 revision) — China Energy Label framework
GB 12021.2-2015 — Minimum allowable values of energy efficiency and energy efficiency grades for household refrigerators (underlying grade standard)
Refrigerators placed on the Omani market must bear the GCC (GSO) energy-efficiency label, which displays a star rating (the higher the number of stars, the more efficient) together with annual energy consumption and rated volume. The label is part of the GSO/GCC energy-efficiency scheme (GSO 2530 and related label measures) and is administered in Oman by DGSM under MOCIIP. Before the label may be affixed, the model must be tested to the GSO methodology (IEC 62552 family) and registered/approved through the DGSM conformity scheme — in practice handled by the in-country importer of record. The label content, format, and Arabic-language requirements are defined by the GSO measures. The energy registration links to the broader DGSM product conformity certificate (see market-access rows).GSO 2530 — Energy efficiency labelling and minimum energy performance requirements for household refrigerating appliances (star-rating label + MEPS)
GSO / GCC energy-efficiency label scheme — Arabic-language label content and format; administered in Oman by DGSM (MOCIIP)
GSO IEC 62552 — measurement basis for the labelled energy-efficiency values
Two mandatory actions with no usable Chinese substitute: (1) GCC star-rating label — the Arabic-language GSO energy label (star rating + annual kWh + volume) must be produced, approved, and affixed per the GSO format; the Chinese 1-to-5 grade CEL cannot be reused. (2) GSO registration/approval — the labelled values must come from GSO-methodology testing (IEC 62552 at Gulf reference conditions) and be approved through the DGSM scheme via the importer; a self-declared Chinese grade is not accepted. The star value also depends on clearing the GSO MEPS floor (see frigom-energy-001), so a China-tuned model may both fail MEPS and require re-labelling. Importers/distributors should confirm the current GSO label format and any star-rating revisions before printing labels.[INFORMATIONAL] The GCC (GSO) star-rating energy label is mandatory for refrigerators sold in Oman and must carry GSO-methodology values approved through the DGSM scheme via the in-country importer. The Chinese 1-to-5 China Energy Label does not satisfy the Omani labelling obligation; a fresh Arabic GSO label and energy registration are required, and the model must clear the GSO MEPS floor.

DGSM Product Conformity / Registration + In-Country Importer of Record (MOCIIP) In China, household refrigerating appliances require China Compulsory Certification (CCC) covering safety (GB 4706.13) and EMC (GB 4343.1) before sale, plus a separate China Energy Label (GB 12021.2) administered by NDRC/SAMR. CCC is a mandatory third-party certification issued by CNCA-designated certification bodies to the manufacturer/holder; there is no requirement for a foreign in-country importer of record, because the certification is for the domestic Chinese market. There is no single Chinese mark equivalent to the consolidated DGSM registration: CCC covers safety/EMC and the China Energy Label covers energy, issued and displayed separately.CCC (China Compulsory Certification) — safety (GB 4706.13) + EMC (GB 4343.1); mandatory; administered by CNCA/SAMR
China Energy Label — Measures for the Administration of Energy Efficiency Labels (NDRC/SAMR); based on GB 12021.2-2015
Household refrigerating appliances entering Oman must clear the product conformity/registration process administered by the Directorate General for Standards and Metrology (DGSM) under the Ministry of Commerce, Industry and Investment Promotion (MOCIIP). For a standard refrigerator this consolidates several requirements into one market-access route: (1) electrical safety to GSO IEC 60335-2-24; (2) EMC to the GSO CISPR 14 series; (3) energy MEPS + GCC star label (GSO 2530); and, where applicable, (4) refrigerant/flammability documentation. There is no single CE-style mark; instead the regulated product is registered with DGSM and accompanied by a conformity certificate issued by a DGSM-recognised conformity body, supported by type-test reports (typically IECEE CB Scheme). Critically, the registration/clearance is held through an in-country importer of record — a legally established Omani entity — because a foreign manufacturer cannot itself register or clear goods. Goods are typically imported through the ports of Sohar or Salalah. Product documentation and labels must be in Arabic and reflect the 240 V, 50 Hz supply.DGSM (Directorate General for Standards and Metrology, MOCIIP) — product conformity / registration scheme for regulated products

Ports of entry: Sohar, Salalah
Chinese manufacturers must build the Omani conformity package from scratch — CCC and the China Energy Label do not substitute: (1) DGSM conformity certificate — issued by a DGSM-recognised body, citing GSO IEC 60335-2-24, GSO CISPR 14, and GSO 2530; typically built on an IECEE CB Scheme report (which can reduce, but not eliminate, re-testing). (2) Energy MEPS + GCC star label — recalculation/registration to GSO methodology. (3) Arabic documentation and labelling — instructions and label content in Arabic; 240 V / 50 Hz rating declared. (4) In-country importer of record — the registration and customs clearance must be held by a legally established Omani importer; a Chinese exporter cannot self-register. (5) Voltage — China-tuned 220 V units may need re-rating/re-marking for 240 V. Clearance is through Sohar or Salalah and is gated on the importer presenting the DGSM conformity evidence.[INFORMATIONAL] Market access to Oman for household refrigerators runs through DGSM product conformity/registration (consolidating GSO safety, EMC, and energy requirements), evidenced by a conformity certificate from a DGSM-recognised body and held through an in-country Omani importer of record. Chinese CCC and the China Energy Label do not substitute. Arabic documentation, a 240 V / 50 Hz rating, and clearance via Sohar or Salalah are required.

Radio Type Approval — Smart / Wireless Refrigerators (TRA Oman) In China, wireless modules in appliances are subject to the State Radio Regulation of China (SRRC) type approval (radio transmission equipment type approval, administered by MIIT) and may also require CCC and Network Access Licence depending on the function. SRRC approval covers frequency, power, and radio parameters for the Chinese market. SRRC approval is for China only and is not recognised by Oman's TRA; a fresh TRA approval is required for the Omani market.SRRC (State Radio Regulation of China) type approval — radio transmission equipment type approval; administered by MIIT
CCC — applicable to certain wireless equipment categories; Network Access Licence where applicable
Refrigerators with wireless connectivity (Wi-Fi, Bluetooth, or other radio modules for smart-home features) require radio/type approval from Oman's Telecommunications Regulatory Authority (TRA) before import and sale, in addition to DGSM product conformity. TRA approval covers the radio module's frequency use, emitted power, and conformity to the applicable radio standards (typically the GSO/ETSI-aligned radio standards). Approval is applied for through an Omani entity (commonly the in-country importer or an authorised agent), and the approved radio equipment must carry any required TRA marking/registration reference. A non-wireless refrigerator does not require TRA approval — only the DGSM conformity/registration route applies — so this requirement is conditional on the presence of a radio module.Telecommunications Regulatory Authority (TRA), Sultanate of Oman — radio/type approval for radio-frequency equipment
GSO / ETSI-aligned radio standards — applicable to Wi-Fi / Bluetooth modules used in smart appliances
TRA type-approval / equipment registration — applied for via an Omani importer or authorised agent
For smart/connected refrigerators this is a structural extra step with no usable Chinese substitute: (1) TRA radio approval — the Chinese SRRC approval is not recognised; the radio module must be approved by TRA against the Omani-applicable (GSO/ETSI-aligned) radio standards before import. (2) Frequency/power conformity — the module's frequency bands and power must be confirmed acceptable in Oman (the permitted Wi-Fi/Bluetooth bands and power masks may differ from China's SRRC limits). (3) Application route — TRA approval is filed via an Omani importer or authorised agent, not by the Chinese manufacturer directly. This requirement is conditional: a non-wireless refrigerator skips TRA entirely and only needs the DGSM route (frigom-market-001).[INFORMATIONAL] Wireless/smart refrigerators destined for Oman require TRA radio/type approval in addition to DGSM conformity; the Chinese SRRC approval is not recognised. The radio module must be approved by TRA (via an Omani importer/agent) against the Omani-applicable radio standards. Non-wireless refrigerators are out of TRA scope and follow only the DGSM route.

Refrigerant — R-600a Flammable Refrigerant Handling (GSO/IEC 60335-2-24 Annex AA) China regulates flammable-refrigerant charge for household appliances primarily through GB 4706.13-2014, which incorporates R-600a flammability provisions derived from IEC 60335-2-24 (charge limits, ventilation, ignition-source requirements). China operates its HFC phase-down under the Kigali Amendment to the Montreal Protocol (ratified June 2021), administered by the Ministry of Ecology and Environment (MEE). Because the Chinese GB 4706.13 R-600a provisions and the GSO/IEC 60335-2-24 Annex AA both derive from IEC 60335-2-24, the technical content is closely aligned — Chinese R-600a refrigerators are generally well-positioned for Oman on the refrigerant aspect, subject to charge and documentation verification.GB 4706.13-2014 — flammable-refrigerant (R-600a) provisions for household refrigerating appliances (derived from IEC 60335-2-24)
GB 9237 — Safety requirements for refrigerating systems and heat pumps (aligned with ISO 5149)
Kigali Amendment to the Montreal Protocol — China HFC phase-down schedule (ratified June 2021, administered by MEE)
Household refrigerators sold in Oman overwhelmingly use R-600a (isobutane, GWP ~ 3), a hydrocarbon refrigerant classified A3 (lower flammability) under ISO 817. For the Omani market the refrigerant aspect is governed primarily through the safety standard: the GSO adoption of IEC 60335-2-24, including Annex AA, which sets the maximum R-600a charge per appliance/compartment configuration, ventilation requirements, and ignition-source provisions. Manufacturers must: (1) verify the appliance charge complies with the GSO/IEC 60335-2-24 Annex AA flammability limits; (2) declare the refrigerant designation (R-600a / isobutane) and charge quantity in grams in the product documentation; and (3) ensure markings and safety instructions (in Arabic) cover the flammable-refrigerant handling and servicing precautions. Oman, as a party to the Montreal Protocol and Kigali Amendment, phases down HFCs; R-600a is not an HFC and is well-positioned, but any HFC-based models (e.g., R-134a) should be checked against current GSO/Oman refrigerant provisions.GSO IEC 60335-2-24 — Annex AA: Requirements for appliances using flammable refrigerants (R-600a charge limits, ventilation, ignition-source requirements) — GSO adoption applied under the DGSM scheme

Montreal Protocol / Kigali Amendment — HFC phase-down framework to which Oman is a party (relevant to HFC-based models, not R-600a)
For R-600a appliances the gap is mainly documentation and charge verification, not a fundamental technology gap, because both GB 4706.13 and the GSO/IEC 60335-2-24 Annex AA share the IEC 60335-2-24 basis: (1) Omani product documentation must explicitly state the refrigerant designation (R-600a / isobutane) and charge weight in grams, with Arabic safety instructions for flammable-refrigerant handling. (2) The R-600a charge must be confirmed within the GSO/IEC 60335-2-24 Annex AA maximum limits for the appliance configuration; a Chinese CCC test report should be checked to confirm it demonstrates Annex AA charge compliance at the configuration sold in Oman. (3) HFC models — any model in the export range using R-134a or another HFC should be assessed against current GSO/Oman refrigerant provisions and the Kigali phase-down before market entry. [NOTE: confirm the exact Annex AA charge limit and any Oman-specific refrigerant provisions against the current GSO/IEC text before regulatory submission.][INFORMATIONAL] R-600a is the dominant refrigerant for Oman-market household refrigerators and is well-positioned (not an HFC). The charge must be verified against GSO/IEC 60335-2-24 Annex AA limits and the refrigerant type and charge weight documented, with Arabic safety instructions. Chinese GB 4706.13 R-600a provisions share the IEC basis, so the gap is mainly documentation/charge verification; any HFC-based models should be assessed against current GSO/Oman provisions and the Kigali phase-down.

Electrical Safety — Household Refrigerating Appliances (DGSM conformity + GSO IEC 60335-2-24) China's mandatory safety standard for household refrigerating appliances is GB 4706.13-2014 (Safety of household and similar electrical appliances — Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers), technically derived from IEC 60335-2-24:2010 but incorporating Chinese national deviations. GB 4706.13-2014 is mandatory (GB) and enforced by SAMR under the China Compulsory Certification (CCC) regime; products must be CCC-certified by a CNCA-designated certification body before sale in China. Chinese domestic appliances are typically rated 220 V, 50 Hz. CCC test reports issued by Chinese laboratories against GB 4706.13 are not, on their own, accepted as the conformity basis under the Omani DGSM scheme, although both China and Oman ultimately trace to the IEC 60335-2-24 family.GB 4706.13-2014 — Safety of household and similar electrical appliances — Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers (mandatory; derived from IEC 60335-2-24:2010 with national deviations; enforced under CCC by SAMR/CNCA)
GB 4706.1-2005 — General requirements (read in conjunction with GB 4706.13)
Household refrigerating appliances placed on the Omani market must demonstrate electrical safety under the conformity scheme administered by the Directorate General for Standards and Metrology (DGSM) of the Ministry of Commerce, Industry and Investment Promotion (MOCIIP). The applicable safety standard is the GSO adoption of IEC 60335-2-24 (Safety of household and similar electrical appliances — Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers), read together with the GSO adoption of IEC 60335-1 (general requirements). Oman, as a GCC member, adopts GSO standards which in turn adopt the IEC 60335 series. Key requirements cover protection against electric shock, insulation resistance and dielectric strength, thermal cut-outs, creepage and clearance distances, mechanical strength, earthing continuity, and appliance markings. Appliances must be rated for the Omani grid of 240 V, 50 Hz. Conformity is normally evidenced by a type-test report (IEC/CB Scheme basis) accepted by a DGSM-recognised conformity body, leading to a product conformity/registration certificate held through an in-country importer.GSO IEC 60335-2-24 — Safety of household and similar electrical appliances — Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers (GSO adoption of IEC 60335-2-24; applied under the DGSM conformity scheme)

DGSM (Directorate General for Standards and Metrology, MOCIIP) — product conformity / registration scheme for regulated electrical products
Grid rating: 240 V, 50 Hz (Oman national electricity supply)
Because both regimes adopt IEC 60335-2-24, an IECEE CB Scheme test report (IEC 60335-2-24 basis) issued by an NCB is frequently the practical bridge — a DGSM-recognised conformity body can convert it into an Omani product conformity/registration certificate, often with limited re-testing. Two gaps remain: (1) Voltage rating — the appliance must be declared and tested for 240 V, 50 Hz Omani supply; a unit rated only for China's 220 V may need re-rating, re-marking, or supplementary type-test evidence for the 240 V condition. (2) Documentation/route — Chinese CCC certification and GB 4706.13 reports are not directly recognised; conformity must be re-established through a DGSM-accepted body and the certificate must be held via an in-country importer of record. National-deviation differences between GB 4706.13 and the GSO/IEC text (socket/plug types, earthing, markings, instruction language — Arabic required) should be reviewed by a qualified conformity consultant before relying on existing CCC test data.[INFORMATIONAL] Electrical-safety conformity to GSO IEC 60335-2-24 (with IEC 60335-1) under the DGSM scheme is mandatory for household refrigerating appliances entering Oman. Chinese CCC/GB 4706.13 certification does not by itself satisfy the Omani route; an IECEE CB Scheme report can usually bridge to a DGSM conformity certificate, but the 240 V / 50 Hz rating and Arabic documentation must be verified, and the certificate held via an in-country importer.
