2️⃣ Required Documentation Checklist 

Complete and accurate documentation is critical for successful certification.

2.1️⃣ Technical Core Documents

  1. Circuit Diagrams & RF Specifications

    • Label all RF-related components and parameters clearly

  2. Technical Specifications

    • Include operating frequency bands, modulation types, output power, and other RF parameters

  3. User Manual in Korean

    • Mandatory; must contain safety warnings and operating instructions


2.2️⃣ Testing & Compliance Documents

  1. Complete Test Reports

    • Issued by a Korean-accredited laboratory

    • Covers RF (frequency, power, bandwidth) and EMC tests

  2. SAR Test Report (if applicable)

    • Required for devices used near the head or body (phones, smartwatches)


2.3️⃣ Administrative & Legal Documents

  1. Korean Authorized Representative Proof

    • Overseas manufacturers must appoint a locally registered company in Korea

    • Provide a Power of Attorney

3️⃣ Validity Period & Maintenance 

KCC certification does not have a fixed automatic expiration, but validity is conditional:

  1. Product Design Changes

    • Hardware, core firmware, antenna, or RF circuitry modifications invalidate certification

    • Requires re-testing or change application

  2. Regulatory Updates

    • Manufacturers must ensure compliance with new Korean technical standards

    • Failure may void the certificate



4️⃣ Practical Guidance ✅

  1. KC Safety Certification Distinction

    • KCC: Governs communication devices and RF compliance

    • KC Safety: Focuses on electrical safety

    • Some devices (e.g., Wi-Fi-enabled smart appliances) may require both certifications

  2. Document & Labeling Requirements

    • Korean user manual mandatory

    • KC Mark and certification number must be permanently displayed on the product

  3. Non-Compliance Risks

    • Customs detention, fines, and denial of market access



5️⃣ FAQs 

Q1: Which devices require KCC certification?

  • All wireless communication devices, including mobile phones, Bluetooth, Wi-Fi, and RFID products.

Q2: What are the essential documents for application?

  • Circuit diagrams, RF specs, technical specifications, Korean user manual, test reports, business license, and local representative proof.

Q3: How many samples are needed?

  • 2–3 fully functional prototypes, identical to mass-production units.

Q4: Does KCC certification expire automatically?

  • No, but design changes or updated standards can invalidate the certificate, requiring re-certification.
