Influencer marketing in Korea is regulated advertising, and the brand carries the risk. Korea's Fair Trade Commission (FTC) sets specific rules on where and how a sponsored post must say it is sponsored, and it holds the advertiser responsible when the disclosure is missing or hidden. The second trap is ownership. By default the creator owns what they make, so turning a well-performing post into a paid ad, or putting it on your product page, needs a license you negotiated in advance. The influencer marketing overview covers platforms and selection. This chapter covers the contract.
What Korean disclosure rules require
The FTC's guidelines on endorsement and testimonial advertising were tightened in 2020 with social media in mind. The core idea is simple: consumers must be able to see that a post is advertising before they read it as an opinion.
- ▸What: any economic interest, including payment, free products, discounts, and commissions. Gifted-only collaborations are not exempt.
- ▸Where: in the title or the first part of the post, visible without tapping 'more'. A disclosure buried after a long caption or inside a block of hashtags does not count.
- ▸How: in clear Korean such as 광고 (advertisement) or 협찬 (sponsored), ideally stating what was received. An English-only '#ad' or vague phrases like 'thanks to' are not treated as clear disclosure for Korean consumers.
- ▸Video and live: disclose at the start and the end of a video, and repeat it during live streams so viewers who join midway see it too.
Platform tools help but do not replace the text. Turn on Instagram's paid partnership label or YouTube's paid promotion setting, and still put the Korean disclosure in the first line of the caption or description.
Who is liable when disclosure fails
Foreign brands often assume the creator is responsible for their own post. In Korea, the advertiser is the primary target of enforcement.
The practical takeaway: write the disclosure duty into the contract, supply the exact wording, and check the live post. 'The creator should have known' is not a defense for the brand.
What the contract has to cover
Korean creators and agencies are used to written agreements, and a clear contract protects both sides. These clauses matter most for foreign brands.
- ▸Deliverables: format, number of posts, length, platforms, posting dates, and whether stories or short videos are included.
- ▸Review and revisions: one or two rounds of draft review with a turnaround time. Unlimited revisions are a common source of conflict.
- ▸Disclosure duty: the creator discloses as the FTC guidelines require, using wording you supply, and fixes any disclosure problem as soon as you ask.
- ▸Claims: the creator only makes claims you can substantiate, and never medical claims for cosmetics or supplements.
- ▸Posting period: how long the post must stay up, commonly several months. Without this clause a post can quietly disappear.
- ▸Exclusivity: whether the creator can work with direct competitors, in which category, and for how long.
- ▸Usage rights: what you may do with the content, where, and for how long. See the next section.
- ▸Payment and tax: fee, schedule, and invoicing. Paying individual creators in Korea usually involves withholding tax, which is one reason foreign brands contract through a Korean agency.
Write the contract in Korean, or in both languages with Korean as the reference version, and agree on the governing law. A creator who cannot read the contract comfortably will not follow its details.
Usage rights decide what you can do with the content
The most expensive surprise in an influencer campaign is finding out that the best-performing post cannot be used as an ad. Rights come in layers, and each layer is priced separately.
Define the media, the territory, and the duration for each layer. 'Unlimited, worldwide, forever' is where negotiations usually break down.
Two details that catch teams out:
- Faces and voices are separate rights. Using the creator's face or voice in your ad needs their consent for that use, not only rights to the post.
- Music is often not cleared for ads. Trending tracks added inside the app are licensed for ordinary posts. If a piece may become an ad, plan for licensed or original audio from the start.
If you plan to boost creator content, see Meta and Instagram ads in Korea, which covers partnership ads. Putting creator photos on your marketplace page is also a usage-rights question; see Korean product detail pages.
A campaign workflow that avoids the traps
- 1Brief with the rules insideKey messages, the claims you can support, the required disclosure wording, and what the creator must not say.
- 2Contract before contentSign deliverables, disclosure duty, posting period, exclusivity, and usage rights before any product ships or any draft is written.
- 3Review the draftCheck the disclosure position and wording, and every claim, before the post goes live. Keep review within the agreed rounds.
- 4Check the live postTake a screenshot of the published post with the disclosure visible. Posts get edited, and your evidence should show what actually went live.
- 5Collect resultsAsk for platform insights such as reach, saves, and clicks within an agreed time, not just the public like count.
- 6Track the rights calendarRecord when each usage right ends, and stop running the content as an ad before it expires.
Common mistakes
- An English-only '#ad'. Korean consumers and the FTC expect clear Korean wording in the first part of the post.
- Asking creators to hide the sponsorship. It exposes the brand to enforcement and destroys trust when it comes out.
- No usage clause. Without one, the post cannot become an ad, a banner, or part of your product page without a new negotiation.
- Unlimited revisions. They sour the relationship and delay the post. Agree the rounds upfront.
- No posting period. A post can be archived a week after payment.
- Paying without a contract. Disclosure, rights, and tax are left undefined, and those are the parts that go wrong.
Frequently asked questions
Is '#ad' enough in Korea?
Usually not on its own. The FTC expects the disclosure in clear Korean, such as 광고 or 협찬, placed in the title or the first part of the post where it is visible without tapping 'more'. Use the platform's paid partnership label as well, but treat it as a supplement to the Korean text, not a replacement.
Do gifted-only collaborations need disclosure?
Yes. A free product is an economic interest, so the post must say the product was provided. The same applies to discounts, commissions, and trips paid for by the brand.
Who is liable if the influencer forgets to disclose?
Primarily the brand. Korea treats the company whose product is promoted as the advertiser, and enforcement is aimed at the advertiser. Put the disclosure duty and wording in the contract, check the live post, and keep screenshots as evidence.
Can we use influencer content in our own ads?
Only if the contract grants those rights. By default the creator owns the content. Paid usage, such as running the post as a Meta partnership ad, is normally priced as an add-on and limited in time. Using the creator's face or voice in an ad needs explicit consent for that use.
Should the contract be in Korean?
Yes, or in both languages with Korean as the reference version. Korean creators work from Korean contracts, and a clause they cannot read is a clause they will not follow. Agree on the governing law, and if you work through a Korean agency, make sure its contract with the creator passes your disclosure and usage terms through.
