Although most advertising law is national, local rules and enforcement priorities in Seongnam-si can affect your marketing activities. Key legal areas relevant to advertising and marketing include:
- Act on Fair Labeling and Advertising: Prohibits false or exaggerated claims, requires substantiation for product claims and gives authorities power to order corrective advertising and impose fines.
- Monopoly Regulation and Fair Trade Act: Enforced by the Korea Fair Trade Commission for unfair competition, deceptive practices, and prohibited commercial practices including unfair comparative advertising.
- Framework Act on Consumers and Electronic Commerce Consumer Protection Act: Set consumer rights for returns, refunds and information disclosure for online transactions.
- Act on Promotion of Information and Communications Network Utilization and Information Protection: Regulates electronic marketing, unsolicited communications and online ad content.
- Personal Information Protection Act (PIPA): Governs collection, use and transfer of personal data for marketing, requiring lawful basis, consent, purpose limitation and safeguards.
- Sector-specific laws: Food Sanitation Act, Pharmaceutical Affairs Act and Cosmetics Act restrict health and efficacy claims and require approvals or notifications for certain products.
- Door-to-door Sales and Telemarketing Regulations: Special rules and cooling-off rights for certain direct sales and telemarketing methods.
- Local ordinances and permit rules in Seongnam-si: Municipal rules may limit outdoor advertising, signboard placement, and promotional activities in public spaces. Local consumer centers also handle complaints and may mediate disputes.
- Enforcement mechanisms: Administrative corrective orders, fines, suspension of marketing activities and in serious cases criminal prosecution. Civil liability and damages claims are also possible.
An advertisement is unlawful if it is false, misleading or likely to deceive consumers about product qualities, performance, origin, price or safety. Unsubstantiated health or efficacy claims, hidden material terms, failure to disclose sponsored content, and breach of sector-specific advertising rules are common grounds for enforcement.
Health and medical claims are tightly regulated. Foods and cosmetics cannot claim to treat or cure diseases unless specific approvals are obtained. The Ministry of Food and Drug Safety sets strict rules on permitted claims. If your product has therapeutic effects you will likely need regulatory approval before advertising those claims.
Sponsored content must be clearly and conspicuously disclosed so consumers understand the commercial relationship. Influencers and brands should document agreements, ensure disclosures meet regulatory standards and avoid exaggerated or unsubstantiated claims. Failure to disclose sponsorship can trigger enforcement actions.
Under PIPA, you must have lawful grounds to collect and use personal data for marketing. Explicit consent is generally required for direct marketing messages, unless a statutory exception applies. You must provide privacy notices, allow opt-outs, and implement security measures. Data breaches must be reported as required by law.
Sending commercial electronic messages without proper consent or without providing a clear opt-out mechanism can be illegal under telecommunications and information network laws. Commercial messages should include sender identification and a way to unsubscribe. Violations can lead to fines and administrative orders.
Comparative advertising is permitted if it is truthful, objective and not misleading. If a competitor believes your comparison is false or unfairly damages their reputation they may seek injunctive relief or damages under the Fair Trade Act or tort law. Keep comparisons factual and verifiable and avoid denigrating claims.
Keep records of the advertisement, promotional materials and any claims or substantiation. Respond promptly to the consumer and to any municipal or national agency inquiries. Consider voluntary corrective measures if appropriate and seek legal advice early to limit exposure and manage regulatory interaction.
