What is KC EMC Certification?

2026-03-12

KC EMC is the mandatory electromagnetic compatibility certification for the Korean market, regulated by RRA (Radio Research Agency).

Without it, you cannot legally sell in South Korea.

I. What is KC EMC?

It verifies two things:

1.EMI: product does not emit excessive electromagnetic interference.

2.EMS: product resists external interference.

Since 2025, all products ≥ 50V AC or ≥ 75V DC require KC EMC — no exceptions.

Important:KC EMC ≠ KC SafetyThey are separate and cannot replace each other.

II. Products That Must Have KC EMC

·Home appliances

·IT and office equipment

·Audio/video devices

·Power supplies & adapters

·Wireless communication devices

·Lighting (new 2026 harmonic limits)

Even small-batch / batch certification requires EMC testing.

III. 2026 KC EMC Core Requirements

·EMI: conducted & radiated emissions

·EMS: ESD ±15kV, surge, EFT

·Standards: KS CISPR 32 (IT/AV), KS CISPR 14-1 (home appliances), KS IEC 61000-4 (immunity)

·Wireless products: add RF and SAR testing

·Testing must be done at RRA-authorized labs

IV. KC EMC Process

1.Product classification

2.Prepare Korean/English documents

3.Test at RRA-accredited lab (2–3 weeks)

4.Submit via agent (1–2 weeks)

5.Issue certificate (valid 5 years)
