Korea KC Mark: Who Needs It and What It Covers

South Korea requires many products sold in its market to carry the KC Mark before they can be imported or offered for sale. For small importers and resellers, the question is usually simple: does my product need it, and what does getting it actually involve.

What the KC Mark Is

The KC Mark is South Korea's certification mark, overseen by the Korea Agency for Technology and Standards (KATS). It signals that a product has been tested and documented to meet Korean safety requirements. Without it, a shipment can be held at customs or refused entry, and the product cannot legally be sold in the country.

Who It Applies To

The KC Mark applies to companies importing or reselling goods into South Korea, regardless of size. If you are bringing in electronics, electrical items, or other regulated goods, you are expected to hold the correct certification before the product reaches Korean buyers or shelves. This applies whether you are shipping directly or working through a distributor based in Korea.

What You Need to Have in Place

Korea KC Mark compliance rests on four main requirements:

**A KC Certificate from a KATS-accredited lab.** This is the core document proving the product has been tested and meets the applicable safety standard. It needs to come from a lab that KATS recognizes, not just any testing facility.

**The KC Mark on the product and its packaging.** Certification alone is not enough — the mark itself has to appear on the item and its packaging in the correct form.

**Safety information in Korean.** Labels, instructions, and warnings need to be available to the end user in Korean, not just the language of the country you are shipping from.

**Importer registration with KATS.** The entity bringing the product into South Korea needs to be registered with KATS as part of the certification record.

Checking Before You Ship

Because requirements vary by product category, the safest approach is to confirm what applies to your specific goods before you commit to a shipment, rather than after it has left the factory. This is also where supplier records matter: if a supplier cannot produce a valid KC Certificate or confirm KATS accreditation, that is worth resolving early.
