About Advertising and Marketing Law in Bang Khun Thian, Thailand

Bang Khun Thian is a district in Bangkok where traditional retail, industrial zones, seafood businesses, logistics hubs, and growing e-commerce activity intersect. Advertising and marketing here are governed by national Thai laws that apply across Bangkok, together with Bangkok Metropolitan Administration requirements for signage and local permitting. Whether you promote products on social media, run in-store promotions, hang outdoor signage, or advertise on radio or TV, your activities must comply with consumer protection rules, sector-specific restrictions, data privacy rules, intellectual property protections, and local permitting practices.

The core principle in Thailand is that advertising must be truthful, not misleading, and fair to consumers and competitors. Regulators pay close attention to claims about health, weight loss, cosmetics, foods, medical devices, and financial services. Promotions that involve chance-based giveaways may require a permit. Personal data used for direct marketing must be handled under the Personal Data Protection Act. Outdoor billboards and building wraps typically require approval, and there is a signboard tax administered in Bangkok.

Why You May Need a Lawyer

You may need a lawyer if you plan a campaign with health, beauty, or performance claims that must be substantiated and in some cases pre-cleared by the relevant regulator. Legal guidance is valuable when structuring promotions, sweepstakes, or lucky draws to avoid violating gambling restrictions and to secure the correct permit if one is required. If you engage influencers or KOLs, counsel can help draft clear contracts, ensure proper disclosure of sponsored content, and manage liability for claims made in posts or live streams.

Businesses also seek legal help to review comparative ads and competitor references, to avoid unfair trade practices or defamation. Agency-client relationships benefit from precise scopes, approvals, IP ownership, and indemnities set out in writing. If you collect or use customer data for targeted advertising, a lawyer can align consent, privacy notices, opt-outs, and vendor agreements with the PDPA and telecom guidance on SMS and telemarketing. You may also need support with billboard permits, signboard tax filings, and building control rules in Bang Khun Thian. In disputes, counsel can respond to regulator inquiries, competitor complaints, takedown demands, or consumer claims.

Local Laws Overview

Consumer protection and misleading advertising. Thai law prohibits false, exaggerated, or deceptive advertising. The Advertising Committee under the Consumer Protection Board issues guidance and can order corrections, fines, or cessation of unlawful ads. Price advertising and discount claims must be accurate and supported by records of regular prices and promotion terms.

Sector-specific claims and approvals. Health-related claims for foods, supplements, cosmetics, drugs, medical devices, and traditional medicines are regulated by the Ministry of Public Health and the Food and Drug Administration. Many claims require supporting evidence, specific warnings, or prior notification or approval. Financial products, insurance, and investment promotions also have specific rules issued by the relevant regulators.

Alcohol and tobacco restrictions. Alcohol advertising is tightly restricted, including limitations on showing brand attributes, discouraging content that encourages drinking, and requiring warning statements. Tobacco advertising is broadly prohibited. Marketing must not target minors.

Promotions, contests, and lucky draws. Chance-based promotions may fall under gambling restrictions. In practice, many prize draws for advertising purposes require a permit from the competent authority in Bangkok, which can involve the police or district office. Skill-based contests should be structured carefully. Terms and conditions must be clear and available to participants, with taxes on prizes handled correctly.

Data privacy and direct marketing. The Personal Data Protection Act governs the collection and use of personal data for marketing. Marketers must identify a lawful basis, provide notices, respect opt-outs, and protect data shared with vendors or platforms. Individuals have the right to object to processing for direct marketing. Telecom rules and guidance also address consent and identification for SMS advertising and telemarketing.

Digital advertising and content rules. Claims made on websites, apps, social media, and live streams are treated the same as other advertising. Disclosures must be clear and prominent on the platform where the claim appears. Businesses should monitor user generated content they amplify or republish. The Computer Crime Act can be implicated by false or misleading online content that causes public harm.

Influencer and endorsement practices. Authorities expect clear disclosure where content is sponsored or where a material connection exists between the advertiser and the endorser. Endorsements must reflect honest experiences and be supported by evidence. Marketers can be held responsible for influencer claims made on their behalf.

Comparative advertising and fair competition. Comparative claims are generally allowed if they are truthful, objective, and not misleading. Unfair trade practices that disparage competitors or cause consumer confusion can violate consumer and competition laws.

Outdoor advertising, signboard tax, and local permits. Large signs, billboards, and building wraps typically require permits under building control rules. In Bangkok, the signboard tax is administered by local authorities and applies to most commercial signage. Placement, size, lighting, and safety standards are enforced. Businesses in Bang Khun Thian should coordinate early with the district office or relevant BMA departments for approvals and inspections.

Broadcast advertising. Broadcast advertisements are subject to National Broadcasting and Telecommunications Commission rules, including content restrictions and time limits. Sponsorship identifications and product placement disclosures may be required depending on the medium.

Language, labeling, and pricing. Certain product labels and mandatory warnings must appear in Thai. For advertising, using Thai is not always mandatory, but required information, warnings, and prices for regulated goods and services should follow Thai requirements and be easily understood by consumers.

Intellectual property and publicity rights. Use of third party trademarks, logos, music, photos, or celebrity images requires permission or a license. Thailand recognizes rights of publicity and privacy. Contracts should address IP ownership in creative materials, licenses for fonts and music, and takedown procedures.

Frequently Asked Questions

Do I need a permit to run a lucky draw or giveaway in Bang Khun Thian

If your promotion involves chance in selecting winners, a permit is often required in Bangkok. The competent authority can be the local police or district office depending on the format. Skill-based contests may avoid this, but the criteria must be genuine and objective. Seek advice before launch, prepare full terms and conditions, and allow time to obtain approvals.

What disclosures are required for influencer or KOL marketing

Sponsored content should include clear and prominent disclosure that the content is advertising or that a material connection exists. Disclosures must appear on the platform and format where the content is consumed, using unambiguous wording. The advertiser remains responsible for the truthfulness of claims made by influencers, and for ensuring claims can be substantiated.

Can I advertise alcohol in Bangkok

Alcohol advertising is restricted. Content must not encourage excessive drinking, target minors, or show prohibited depictions. Warning statements are required. Many creative approaches that are common in other countries are not permitted in Thailand. Pre-launch legal review is recommended for any alcohol-related campaign.

What health or weight loss claims can I make

Health and functional claims must be accurate, supported by reliable evidence, and comply with product-specific regulations. Some claims require prior approval or pre-marketing notification. Prohibited disease claims and exaggerations can trigger enforcement and product seizures. Always align advertising with the product registration and labeling approved by the relevant authority.

Are comparative ads allowed against competitors

Comparative advertising is generally permissible if it is truthful, fair, verifiable, and not misleading. You must compare like-for-like products, cite objective criteria, and avoid disparaging language. Keep substantiation on file and be prepared to show it to regulators or broadcasters.

What are the PDPA rules for email and SMS marketing

You must have a lawful basis to use personal data for direct marketing, provide privacy notices, and honor opt-outs. Individuals can object to direct marketing at any time. Identification of the sender and a simple unsubscribe method are expected for electronic messages. If you use third party vendors, ensure data processing agreements and adequate safeguards are in place.

Do ads need to be in Thai

There is no universal requirement that all advertising be in Thai, but mandatory warnings, product information for regulated goods, and pricing disclosures often must be in Thai or must be readily understood by Thai consumers. For consumer-facing campaigns in Bangkok, Thai language is typically used to ensure clarity and compliance.

What approvals are needed for billboards or building wraps in Bang Khun Thian

Large outdoor signs generally require building control approval and are subject to safety and placement rules. In Bangkok, the signboard tax applies to most commercial signage and must be filed and paid annually. Coordinate with the district office early, as site inspections and structural documents may be required.

Can I use celebrity images, music, or user photos in my ads

You need permission or a license for third party IP and for a person’s image or likeness. For user generated content, obtain explicit consent covering advertising use. Keep records of licenses for logos, music, fonts, and stock imagery, and ensure the scope covers your media plan and territory.

How are fake reviews and testimonials treated

Misleading reviews, undisclosed incentivized testimonials, or fabricated ratings can violate consumer protection laws. If you feature reviews in ads, ensure they are genuine, typical, and not cherry-picked in a misleading way. Disclose any incentives and keep documentation to substantiate endorsements.
