KC Safety Certification

Safety Certification

In order to prevent safety accidents caused by fire or electric shock caused by electrical appliances, the manufacturer of the product subject to safety certification (including those manufactured abroad and exported to the Republic of Korea) or importer shall obtain safety certification from the safety certification authority for each model of the product subject to safety certification (domestic manufacture), and import product (import product) in accordance with Article 5 of the Electrical Appliances Safety Management Act.

This procedure verifies the safety of products before market distribution by testing products that are subject to safety certification in accordance with safety standards and by examining factories to see if the quality of products subject to certification can be maintained continuously.

Factory Assessment The manufacturing, management, shipment, and maintenance capabilities of the plant that produces the products subject to safety certification are checked for safety, and regular inspections are conducted during production or distribution of the products that have been certified for safety.

  • Initial Factory Assessment (1) Checking whether the manufacturer of electrical appliances and the manufacturing plant are true or not
    (2) Checking compliance with testing, inspection equipment, and quality systems
  • Regular Factory Assessment (1) Checking whether the manufacturing plant in the safety certificate is producing the product
    (2) Check whether the same parts are used as the safety management list attached to the safety certificate.
    (3) Checking compliance with safety standards and safety certification details of products that have received safety certification
    ※ Regular inspection is a follow-up management system that checks whether a product with safety certification is maintained continuously.
    The manufacturer shall conduct a self-inspection and prepare and keep the records. (Manufacturer pays for regular factory inspection)
Safety check

The safety confirmation system was introduced to apply safety management procedures differently according to the level of hazards in consideration of environmental changes such as the increase in the supply of new products and the need for deregulation of companies due to the development of the electric and electronic industries.
Product subject to safety verification, implemented from January 1, 2009, shall be exempted from factory review and regular inspection procedures applied to existing products subject to safety certification.
The manufacturer or importer of the product subject to safety verification receives safety verification tests from the safety verification testing agency for each model, and the product subject to safety verification meets the safety standards.
After checking it, report it to the relevant certification authority.

Suppliers of conformity

The manufacturer or importer of the electrical equipment subject to supplier compliance shall conduct a product test for each model of the electrical equipment or request a third party to verify that the electrical equipment meets the safety standards.
Pursuant to Article 14-3 (3) of the Act, the manufacturer or importer of electrical appliances subject to supplier compliance shall keep the following documents for 5 years from the date of final manufacture of the relevant electrical appliances

A mark for verification of suitability of suppliers of safety certification reports (indications shall be affixed so that they do not fall where they can be easily identified on the product or package, or marked by printing or imprinting, but shall be marked on the product in principle).
2. Safety verification report number
3. Product name and model name
4. Manufacturer's or importer's name (add manufacturer's country of manufacture only for foreign material manufacturers)
5. A mark to indicate the date of manufacture of the product (e.g., a date of manufacture, a lot number, or a mark to prove the manufacturer's date of manufacture, etc.)
6. Contact A/S (domestic contact with real A/S availability)
7. Indications stipulated in the individual electrical equipment safety standards
8. Warning statements or precautions
9. Rated voltage, rated frequency, and rated consumption power (simultaneously with the marking method in accordance with international standards)
10. Testing institution (in the case of a third party's requested test)
※ If the electrical equipment is smaller than 900 mm2 and it is difficult to mark the entire display, mark KC and mark the remaining marks not marked on the product.


(1) The size of the shape shown can be adjusted flexibly according to the size of the product.
(2) Attach, print, or imprint the product or package so that it does not fall where it can be easily identified.
(3) In the case of wires
- For non-fluorinated wires, mark the surface of the wire in a way that does not easily erase every 1m or less. However, for other than iodine, safety certification numbers and rated voltages (excluding neon wires) may be considered when marking the safety certification and rated voltage on the label for each volume.
- Every volume should be labeled in a way that is not easily erased on the fluorine insulation front.
(4) In the case of bulbs, they shall be marked on each product in a way that does not easily erase where the surface is easy to see and where the surface of the package is easy to see. However, it is difficult to mark on the product among small-sized, decorative, and incandescent bulbs, and safety certification for packaging each product. Indications other than marks and safety certification numbers may be displayed in a place that is easy to see on the packaging surface, and product classification and regional classification may be excluded from the safety certification number if packaging is not done for each product.
