OCPB Issues New Guidelines on Fair Advertising and Use of AI-Generated Content
Background: What is Happening in Thailand Now:
Thailand has taken a significant step toward regulating the use of artificial intelligence in commercial advertising. The Office of the Consumer Protection Board (OCPB) has issued a formal notification under the Consumer Protection Act B.E. 2522 (1979) establishing specific guidelines for AI-generated advertising content.
The notification addresses emerging advertising practices where marketers increasingly use AI and image-editing software to create or enhance visuals—often to an idealized standard—to attract consumer interest or build credibility. The OCPB observed that such practices may cause consumers to misunderstand the essential characteristics, condition, quantity, or usage of products, which violates consumer rights and causes damage.
Key trigger for regulation: The OCPB determined that when advertisements use images, videos, or other visual materials that have been created, enhanced, or modified through AI or computer programs, consumers may be misled about the actual product they will receive. The notification is already in effect with no grace period.
Why the Regulator Needs to Regulate:
The OCPB identified several risks justifying regulatory intervention:
· Consumer deception: AI can create flawless, exaggerated depictions that mislead consumers about the true characteristics, quality, quantity, or composition of products.
· Unfair competition: Advertisers using deceptive AI enhancements gain an unfair advantage over those that accurately portray their products.
· Vulnerable group protection: Children and adolescents are especially susceptible to unrealistic AI-generated images, which may encourage unsafe behavior—particularly for non-edible products resembling food items.
· Lack of transparency: Without mandatory disclosure, consumers cannot distinguish between real and AI-generated content, eroding trust in advertising.
The notification was issued under the Consumer Protection Act B.E. 2522 (1979), which has long prohibited advertising that is unfair to consumers or may cause harm to society, including false or exaggerated statements that may cause material misunderstanding about products or services.
What the Regulation Is:
The OCPB notification applies to advertisements using still images or videos created or edited with software programs or AI tools that may cause the depicted product or service to differ from the actual product sold, which may cause misunderstanding regarding condition, quality, quantity, or other essential aspects.
Three Key Requirements:
A. Prior Authorization
Obtain approval from relevant regulatory authorities where required by law. This applies where existing laws already mandate pre-approval for certain advertising categories (e.g., health products, financial services).
B. Accurate Representation
Ensure that the advertised size, quantity, volume, number, or composition matches the actual product or service being sold, whether in still images or videos.
C. Mandatory AI Disclosure Labels
Display clear disclosures when AI or software is used to create or edit images. The OCPB has specified approved wording for these labels :
Approved Disclosure Label When to Use
“Real image or simulation edited using AI” Content showing real product/location with AI editing
“Photo from actual location or simulation edited using AI” Location-based content
“Photo from actual product or edited simulation” Product-focused content with AI enhancement
“Image created by AI” Fully AI-generated images
“Video created by AI” Fully AI-generated videos
Disclosure clarity requirement: Disclosures must be clearly visible, audible, or readable according to the type of advertising medium. A label buried in fine print or shown for only a fraction of a second does not meet this standard.
Separate Rule – Non-Edible Products Resembling Food Items
For non-edible products advertised in a manner that may cause them to resemble food items, businesses must additionally:
· Obtain prior authorization from the relevant regulatory authority when required by law
· Include clear, prominent Thai-language disclaimers that are easily visible, audible, or legible
· Exercise particular caution for communications targeting vulnerable groups (children, adolescents), avoiding portrayals that could encourage imitation, ingestion, or unsafe behavior
What Businesses Need to Do Now:
The notification is already in force. Businesses operating in Thailand must take immediate action :
Step 1: Audit Current Advertising Content
Review all active campaigns and identify any materials that use AI-generated or AI-edited images or videos. Determine which disclosure label applies to each piece of content.
Step 2: Verify Accuracy of Depictions
Ensure that every visual depiction of size, quantity, volume, composition, or characteristics matches the actual product. If discrepancies exist, correct the content or add appropriate disclosures.
Step 3: Add Mandatory Disclosures
For all AI-generated or AI-edited visual content, add one of the OCPB’s approved disclosure labels in a clearly visible position. The label must be readable on screen or in print, and audible if the medium is audio/video.
Step 4: Update Internal Workflows
Make AI disclosure a mandatory step in the creative approval process. Every piece of advertising content that uses AI should be reviewed for compliance before publication.
Step 5: Review Contracts with Agencies and Suppliers
If working with external marketing agencies, graphic designers, or content creators, ensure contracts require them to flag AI-generated content and apply appropriate disclosures. Establish clear compliance responsibility.
Step 6: Train Marketing Teams
Educate all personnel involved in creating or approving advertising materials on what counts as AI-generated or AI-edited content and what disclosures are required.
Step 7: Establish Ongoing Monitoring
Thailand’s AI regulatory landscape is evolving rapidly. Monitor updates from the OCPB and other relevant bodies—including the Ministry of Digital Economy and Society (MDES)—for new guidance.
Key Takeaways:
· Thailand’s OCPB notification on AI-generated advertising content is already in effect under the Consumer Protection Act B.E. 2522 (1979).
· Mandatory disclosure labels with specific approved wording must appear on all AI-generated or AI-edited advertising images and videos.
· Accuracy requirement: Depictions of size, quantity, volume, composition, and characteristics must match the actual product.
· Prior authorization remains required for advertising categories already subject to pre-approval (health products, financial services, etc.).
· Separate rules apply to non-edible products resembling food items, requiring Thai-language disclaimers and special care for vulnerable groups.
· Businesses should immediately audit, correct, disclose, and train to ensure compliance and avoid enforcement risks including fines and removal orders .
· Thailand’s broader AI regulatory framework is still developing—companies should treat this as the beginning of an ongoing compliance journey .
