For those long‑term exporters of Korean household appliances – pay attention. In 2026, KC certification has seen multiple standard updates – with vacuum cleaners the most affected. Many companies fall into the trap of applying against 2024 standards – only to find themselves restricted at customs – wasting the certification fees already spent.

In January 2026, KATS (Korean Agency for Technology and Standards) issued WTO notification G/TBT/N/KOR/1333 – initiating revisions to seven household and similar appliance standards – covering vacuum cleaners, heaters, massage appliances, fluorescent lamps, and lamp control devices.

The new standard for vacuum cleaners is KC 60335-2-2:2025 – aligned with IEC 60335-2-2 Ed.7.0 – with significant changes to test methods and conditions compared to the old version.

Another key policy took effect on 1 April 2026: vacuum cleaners, washing machines, dryers, microwaves, and bathroom appliances – switched from Safety Certification to Safety Confirmation – factory audits and annual surveillance are no longer mandatory. For manufacturers in these categories, certification timelines and compliance costs are now lower. However: this does not mean regulatory oversight is relaxed – random market inspections and document checks continue – compliance awareness must remain.

1. KC – Three Compliance Areas – Key Distinctions

1.1 Safety access

KC safety access is a hard requirement for Korean electrical/electronic products – regulated by KATS. Mains‑powered, battery‑charged, or heat‑generating appliances – all must complete this to circulate in Korea. Safety access covers only electrical safety risks – wireless RF and electromagnetic interference are not assessed – this is the most basic threshold.

Vacuum cleaners and household appliances follow the KC 60335 series – KS C IEC 62368-1 applies only to IT and audio‑video equipment – don't mix them. Standard test items:

·Clearance, insulation withstand, earthing continuity.

·Temperature rise, overload protection, fire‑resistant structure.

·For battery‑powered models: add KS C IEC 62133 battery safety testing.

1.2EMC

KS C IEC 61000 series is the general EMC standard – most electrical products must comply. Small appliances: reference KS C IEC 61000-3-2 for harmonic current requirements. Vacuum cleaners with drive motors – EMC focuses on conducted and radiated emissions.

1.3RF

Products with wireless transceiver capability require KC RF – managed by RRA. Korea's wireless device classification system took effect in 2025 and is now fully operational:

·Class 1: low‑risk – simpler procedures, lower test costs.

·Class 2: higher‑risk – full RF testing + EMC.

Devices with 5 GHz Wi‑Fi – DFS is mandatory – interference avoidance with weather and radar facilities – this rule has never been relaxed.

  2. Vacuum Cleaner – New Standard Core Changes

2.1KC 60335-2-2:2025 – what's changed

Vacuum cleaners and floor washers now use KC 60335-2-2:2025 – aligned with IEC 60335-2-2 Ed.7.0. Changes are concentrated in several areas:

·Clauses 11, 15, 19, 21 – updated heating, mechanical strength, and abnormal‑condition tests.

·Part 2 reference documents and Part 3 terminology definitions also revised.

Clarification: battery runtime and dust‑bin sealing are product performance metrics – not KC safety mandatory test items. Poor dust‑bin sealing allowing dust to enter the motor – a product design risk – but not a certification mandatory test.

New projects must be tested against the latest standard – old‑standard reports are not accepted by KATS.

2.2 Five appliance categories – mode change impact

Vacuum cleaners moving from Safety Certification to Safety Confirmation – factory audits and annual surveillance removed.

·Safety Certification (old): no fixed validity – maintained by annual surveillance.

·Safety Confirmation (new): 5‑year fixed validity.

Regulatory oversight has not decreased – document reviews and random market inspections continue. Korea conducts regular offline product inspections – if product structure or critical components differ from certified records – goods are delisted and penalties apply. Coupang and Gmarket continue to check KC qualifications and markings – non‑compliant products risk platform delisting.

With the mode change, typical test timelines are now 3–6 weeks. Final quotes depend on sample quantity, additional test items, and lab choice – plan ahead.

  3. Smart Appliances – Additional Compliance Requirements

3.1Cybersecurity assessment – not universally required

Korea does not currently mandate cybersecurity assessment for all connected household appliances. Controls mainly target information‑collection terminals (cameras, smart gateways). For exporters, confirm with buyers or sales platforms whether additional requirements apply.

Many ask about smart vacuum cleaners with Wi‑Fi and APP remote control – ordinary connected home appliances are not subject to mandatory cybersecurity assessment. Korea's IoT security rules took effect in 2025 – but enforcement focuses on information‑collection terminals – ordinary appliances do not have a uniform mandate.

3.2Korean documentation and labelling

Korean manuals are critical review materials – must be human‑verified – with complete safety warnings, usage instructions, and troubleshooting. Machine translation, or English/Chinese‑only – likely to be rejected. Manual descriptions not matching the actual product – a frequent rejection reason.

KC safety marks must be clearly printed on the product body or outer packaging – with model, rated voltage, power, and other key parameters. Only very small products – after assessment – may place markings in the manual. Incorrect mark position or model parameters – customs inspection issues.

  4. CB Report to KC – Practical Points

4.1CB reports with Korean national differences

CB reports that include Korean national‑difference test content – some data can be reused – reducing duplicate testing. Ordinary generic CB reports – missing Korean differences – cannot be directly used for KC conversion.

Clarification: CB conversion only applies to safety test items – EMC and RF still require independent testing – CB cannot exempt them. The testing reduction varies by product and report completeness – the claim that "half the testing can be reduced" does not match reality.

4.2Critical component selection

For adapters, lithium batteries, fuses, thermostats – if they're on the KC mandatory list – choose models with valid KC certification – reducing retest workload and shortening review timelines. Using uncertified components – agencies will typically add component‑specific tests – extending timelines and increasing costs.

For battery‑powered models, we recommend scheduling battery testing separately in advance. KS C IEC 62133 battery testing can run in parallel with whole‑product safety testing – avoiding situations where battery performance holds up the entire project.

In 2026, KATS completed safety‑standard terminology unification and text revisions for 34 electrical product categories – standards versions have been updated – companies must continue tracking policy changes – to avoid qualification lapses after transition periods.

4.3Certificate validity and change control

Safety Confirmation certificates: 5‑year validity – start renewal three months before expiry. If product structure, critical components, or factory change – submit a change application in advance – only after approval can the existing certificate continue to be used. Market surveillance is tightening – discrepancies between certification records and actual products create compliance risks.

4.4 Pre‑submission checklist

·Confirm standard version uses the latest (post‑2025) edition.

·Battery‑powered models: start battery testing early.

·If using CB transfer: verify national differences are included.

·Smart models: confirm whether additional assessment is required.

For Korea exports – also check Korean labels and manuals. Korean safety warning wording should match KATS review habits – machine‑translated text often gets revision requests. Ensure certificate model, product‑engraved model, and packaging‑printed model are all consistent. KC mark, electrical parameters, manual, and packaging must all align – any inconsistency will create problems during inspections.

KC certification isn't overly complex – but standards update quickly – using outdated standards will fail. 2026 coincides with vacuum cleaner standard updates and five‑category mode changes – a good window to review compliance strategies. Get the certification right – and customs clearance and sales will be much smoother.
