KC certification for South Korea

Electrical safety. Products in scope are grouped by risk, with a higher-risk group requiring third-party certification and lower-risk groups following lighter routes supported by testing and records. Which group your product falls into decides the cost, the timeline and whether a third party has to be involved at all.

Radio. Anything that deliberately transmits is a separate approval under separate legislation with its own body and its own process. It is not covered by an electrical safety approval and it does not cover one.

Other schemes exist for other product families, and a product can touch more than one. This page publishes no category lists and no tier assignments, because those decide an individual product and are exactly the sort of detail that goes stale in a guide while remaining authoritative on the Korean side.

The practical consequence: get a written scope before you accept a price. "KC certification, USD X" is meaningless without the scheme, the tier and whether the radio side is included. This is the single commonest reason a Korean launch is late — not the work, but the discovery halfway through that only half of it was quoted.

And a battery product adds transport documentation on top, which is a third strand with its own timeline.

Korean approvals are published, and the records can be searched. That makes a KC claim one of the very few compliance assertions in this subject that a buyer can verify independently, from a laptop, before any money moves.

What to do with that. Ask the supplier for the specific certification identifier for the exact model, look it up, and read three things: whose name holds it, which product it covers, and which scheme it belongs to. A record that exists but covers a different model, or a different scheme from the one your product needs, is a record that answers a different question.

Whose name is on it matters as much as here as it does with an FCC grant. If the holder is the factory or a module maker rather than you, establish what that means for a product sold under your brand and whether you need your own.

And check that the scope matches how you will actually sell. An approval covering a model without the radio, or with a different antenna or power configuration, is not an approval for the product you are shipping.

A screenshot is not a check. Search the register yourself — the whole value of a public record is that it does not depend on what somebody sends you.

As with Japan, the practical question is who in the destination market carries the obligations for goods placed there. That is a commercial arrangement — an importer, a distributor, or an entity of your own — and it has to be settled before production because it affects the paperwork, the marking and who can be contacted by an authority.

It also affects control. A distributor who holds the approval in their name holds something you may need if the relationship ends, which is a normal commercial risk and one worth pricing in at the start rather than discovering at renewal.

Labelling and the language of the accompanying information are part of the requirement, not an afterthought. Marking and documentation expectations mean artwork and manuals have a lead time attached to a decision that may not have been made.

Ask a prospective Korean partner exactly what they will hold, in whose name, and what happens to it if you change partner. A partner who has done this before answers immediately; one who has not will say it is handled.

Establish the scope first: which schemes apply, which tier on the electrical side, whether the radio side is in play, and whether a battery adds transport documentation. Get that in writing before accepting any quotation.

Then settle who is responsible in Korea, because the marking and the records attach to them and the artwork depends on it.

Then have the factory's existing test data reviewed against the Korean requirements by whoever will be responsible, rather than assuming CE or FCC data transfers. Some of it will be useful engineering evidence; none of it is a Korean approval.

Then check the register once the approval exists, and keep the identifier where your team can find it — a marketplace or a customer asking for it gives you days, not weeks.

And name in the specification the components and the radio module the approval depended on, with a change-notification clause. The way a Korean approval quietly stops applying is the same way an FCC grant does: a cost-down nobody mentioned.
