In the event that any conditions have to be fulfilled by consumers for them to receive such free service, business operators or advertisers would need to fully describe such conditions※4.

In case of doubt, business operators or advertiser bear the burden of verifying and confirming the results of such test or experiment※6;
• (3) Advertisements that contain (i) an exemption, (ii) a limitation of liability or (iii) a reservation of the right to change the conditions attached to goods or services without prior notice or any advertisements of a similar nature that are disadvantageous to consumers should not be used, for example:
  • “The company reserves the right to change the price and conditions without prior notice”
  • “The company reserves the right to change the price of goods”
  • “The product image is only a sample and may differ from the actual product being promoted”※7;
• (4) Advertisements that appeal to one’s spiritual beliefs or advertisements of a similar nature that are persuasive to consumers with the same spiritual beliefs in a way that would encourage them to buy goods or services should not be used, for example:

• (5) When making advertisements that provide a guarantee in relation to goods or services, business operators or advertisers need to indicate the guarantor, guarantee period, type, scope, procedure, method and conditions of the contractual performance of such guarantee. Examples are as follows:
  • “If you are not satisfied, you are entitled to a refund”

• (6) For advertisements that affirm facts, compare the product or service quality with other similar products or services, or make references to any academic report, research results, statistics, or certification of any institute or person, including any awards won, business operators or advertisers have the duty to prove the claim※10. Examples are as follows:
  • “The Best Product” or “Perfect Service”
  • “First in Thailand” or “The only one in Thailand”
  • “No.1 Sales”
  • “Better than…”
  • “100% effective”

Under the Notification of Guidelines on Advertising Statements, business operators or advertisers are required to prove the claim found in the type of advertisement identified in six (6) within fifteen (15) days from the date of receiving the notification from the Advertisement Committee. For other advertisements that the Advertisement Committee consider to be false or exaggerated, the Advertisement Committee may order the advertiser to prove such claim※11 as well.

Note that the advertisement of certain products such as medical devices, food, cosmetics are controlled by specific regulations issued by the authority in charge. Thus, in case business operators or advertisers will advertise these products, it is necessary to also comply with the requirements of advertisement of such products under its relevant regulations.

3. Conclusion

The Notification of Guidelines on Advertising Statements aims to raise awareness among business operators or advertisers when making advertisements to promote their products or services. Business operators or advertisers need to be careful when making advertisements in which the truth of the stated fact is difficult to be proven. This is because if a business operator or advertiser (i) cannot prove such fact or (ii) make the advertisement in violation of this Notification of Guidelines on Advertising Statements, such advertisement may be deemed to be an advertisement that is unfair to consumers or that may cause adverse effects on society. As a result, the business operator or advertiser may be subject to orders of the Advertisement Committee, for example, revisions to the advertisement may have to be made, a prohibition of the usage of particular statements, etc., may be put in place, or criminal liability under the Consumer Protection Act of 1979 may be imposed.
