Marketing that works elsewhere can create legal exposure in Korea. The country regulates advertising and product labeling closely, with a general prohibition on false, exaggerated, or deceptive claims and a layer of sector-specific rules for areas such as food, health functional products, cosmetics, and finance. For a foreign company launching products or campaigns, aligning marketing with these standards is a core compliance task, not a creative afterthought.
The general rule against deceptive claims
Korean law, principally the Act on Fair Labeling and Advertising, prohibits advertising that is false, exaggerated, deceptive, or unfairly comparative, where it could mislead consumers and harm fair competition. The test focuses on the impression given to an ordinary consumer, not merely the literal truth of a statement. Substantiation matters: if you make a performance or comparison claim, you should be able to support it. Omitting material facts can be as problematic as stating something untrue.
Labeling and sector-specific layers
Beyond general advertising rules, many products must carry specific labeling, such as ingredient, origin, safety, or usage information, and certain categories are governed by their own regulators. Health and food-related claims are tightly controlled, and unapproved efficacy claims are a frequent source of enforcement. Imported goods often carry additional labeling and language requirements, and the responsible importer or local distributor may bear specific duties. Reviewing which regime applies to your product before launch is essential, because relabeling or recalling stock after it reaches the shelves is both expensive and damaging to a new brand.
Influencers, reviews, and endorsements
Korea has moved firmly to require that paid or sponsored promotions be clearly disclosed. Where a company provides compensation, free products, or other benefits in exchange for content, the commercial relationship must be made transparent to the audience. Disguised advertising presented as a neutral review can expose both the brand and the creator. Companies running influencer campaigns should build disclosure requirements into their contracts and monitor compliance.
Keeping campaigns compliant
Review advertising copy and creative against the deceptive-claims standard, retain evidence supporting factual claims, confirm product labels meet the applicable category rules, and ensure sponsored content is properly disclosed. Where claims touch regulated sectors, check whether prior review or approval is expected. Building a simple internal sign-off process, with one person responsible for approving claims, catches most issues before they reach the market and creates a record that you acted in good faith.
