The Effects of Thailand’s Competition Law and Its Application to the Food Delivery Market

Informed Counsel

Thailand’s long-awaited new Trade Competition Act B.E. 2560 (2017) (TCA) came into effect on October 5, 2017, and the legislation’s extensive reforms of both substantive and procedural rules from the preceding version of the law have been both effective and revolutionizing. Significantly, the TCA lays out an efficient structure for the Trade Competition Commission (TCC) and grants independence to its administrative office, the Office of Trade Competition Commission (OTCC). Consequently, enforcement of this law—which had been almost absent in the past 20 years—is picking up pace. This article will examine the ongoing developments under this law in recent years, and will highlight its current application by discussing some of the TCC’s latest guidelines.

TCC: A Developer-Regulator

Since its establishment in 2018, the TCC has proven that its role and responsibilities are beyond those of a conventional regulator and law enforcer. The OTCC, with the support of its ad hoc subcommittees, have been actively monitoring the conduct of business operators and the level of competition in various markets and sectors, and the commission is well recognized for its publicizing of the TCA and establishment of new regulations under the law. Through various channels and platforms, a series of regulations, reports on market conditions, press releases, rulings, and precautionary statements have been published, and the TCC’s spokesperson often appears in the media to educate the public. To streamline the exchange of information and collaboration, the TCC and the OTCC have entered into an MOU with six sectoral regulators, including the Securities and Exchange Commission of Thailand, the Office of Insurance Commission, and others.

The TCC has also exercised its pre-emptive power to prevent suspicious trade practices and transactions. Prohibitive warnings have been issued against potential infringement, such as unfair trade practices by food delivery platform operators and a proposed merger by potentially market-dominating major hospitals.

The TCC has realized that promotion of compliance is equally important to enforcement. Besides regulations and notifications, which set forth rules and restrictions, the TCC has started to promulgate handbooks, general guidelines, and market-specific guidance, as summarized in the table below.

The TCC has the authority to rule on alleged violations and to approve or deny merger applications. All cases the TCC has received so far have been processed swiftly, and decisions—together with their reasoning—have been published with remarkable efficiency. The charts below illustrate statistics for the cases decided by the TCC during the 2019–2020 period. Notwithstanding the relatively low number of cases that resulted in penalties, it is notable that these penalties have been applied evenly and are far-reaching. The infringers on whom fines were imposed or cease-and-desist orders served include a large energy drink manufacturer, modern trade businesses, and a car supplier. Because of their reputations and the amount of the fines, these penalties have attracted much attention from the public and the media. Further public attention was garnered during the USD 10.6 billion acquisition of one large retailer by another Thai retail giant in late 2020 (which the TCC eventually approved with certain conditions), which put the TCC’s discretionary role in the spotlight and has become a landmark merger control case in Thailand.

Guidelines on Unfair Trade Practices

The object of the unfair trade practices provision of the TCA is to prevent any trade practices that cause damage to other operators. This provision has an extensive reach and may prohibit trade practices that have become common in some industries. Over time, the TCC will fine-tune their approach by observing and studying specific markets or industries and actively seek out unfair trade practices or arrangements and suffering parties. To date, the TCC has found four specific industries in which the commission has deemed it necessary to intervene and regulate market conduct of one party in order to protect another mistreated party. As a result, the TCC has launched market-specific guidelines for modern trade, franchise business, fruit trading, and—most recently—food delivery. To demonstrate more clearly how the TCC can intervene, the following section will look at this latest guidance in detail.

Food Delivery Guidelines

The COVID-19 pandemic brought phenomenal growth to e-commerce trading and food delivery services via online platforms, on which restaurant operators have become more and more dependent. The growing market power of the platforms prompted the TCC to issue guidelines to control the platform operators’ conduct, particularly when it comes to their trade practices and contract terms and conditions for participating restaurants.

The Guidelines on Unfair Trade Practices between Digital Platform Operators for Food Delivery and Restaurants were published in the Government Gazette on November 23, 2020, and took effect on December 23, 2020. The guidelines describe best-practice principles and indicate the arrangements, conditions, and restrictions that food delivery platform operators may or may not impose upon restaurants participating in their platform.

The main principle set forth in the TCC’s food delivery guidelines is that the business conduct and commercial conditions imposed by platform operators on restaurants must be fair, noncompulsory, and nondiscriminatory, and must not obstruct another party’s business operations. Furthermore, terms and conditions of the business arrangement should be written, clear, and justifiable.

The TCC’s guidance also contains the following list of conduct that could be deemed unfair under the TCA:

  1. Unfair charges, such as unjustified increases in commission fees or gross profit, discriminatory charging of different rates among similar restaurants, charging advertising fees or promotional expenses for no benefits in return, and unexpected charges or demands for remuneration or benefits.
  2. Setting trade conditions to impede the operations of competitors, such as prohibiting restaurants from participating in other food delivery platforms without justification.
  3. Unfairly exploiting superior bargaining power, such as by forcing restaurants to sell the same type of food at the same price in all sale channels without justification.
  4. Extending credit terms, terminating agreements, and excluding restaurants from the platform without justification.

The guidelines seem favorable to restaurant operators, who may now be able to avoid challenging these practices through potentially lengthy and costly legal proceedings. Instead, restaurateurs are given the right to file complaints with the TCC against food delivery platform operators that may have breached the guidelines. If found guilty, platform operators could incur a hefty fine—up to 10% of their last annual revenue—plus a cease-and-desist order from the TCC to bring the infringement to an end, or other remedial measures.

The TCC’s movements in this area exhort digital platform operators to review and reassess their agreements, business conduct, trade practices, and conditions or directions for restaurant operators. Platforms may also need to seek legal counsel to ensure that their planned actions will comply with the TCC’s guidance before they launch new marketing initiatives or modify existing terms and conditions, especially in relation to prices and fees for restaurant operators.

Conclusion

These guidelines for food delivery platforms are the first attempt by the TCC to regulate the e-commerce market, an industry that has developed rapidly in Thailand. The commission’s action here shows its intent to stay vigilant and ready to move on relevant emerging issues, and it signals that there could be further action on the conduct of e-commerce operators in Thailand if a need is seen. Overall, we can conclude that the revamped trade competition legal and regulatory environment in Thailand—starting with the updated TCA in 2017—has truly set in motion significant changes that aim to provide a fair and equitable field for doing business in Thailand.

On July 31, 2026, the Trade Competition Commission of Thailand (TCCT) launched a one-month public consultation period on proposed regulatory guidelines for competition in three business segments: (1) digital platforms; (2) modern trade and credit terms; and (3) ride-hailing and on-demand delivery, including food delivery and mart/quick commerce. At the same time, the TCCT released a market report on ride hailing and on-demand delivery that is likely to influence the guidelines and their interpretation and enforcement. The consultation runs until August 31, 2026. Stakeholders have a limited window to submit practical, evidence-based input that may shape the next phase of Thailand’s regulatory framework for competition. Scope of the Consultation The public consultation targets updating existing guidance in three business sectors that have experienced transformative growth and structural change: Digital platforms: The TCCT has actively monitored this sector in recent years and has coordinated with other regulators, primarily the Electronic Transactions Development Agency (ETDA) and the Ministry of Commerce. In March 2026 the TCCT’s Guidelines on Multi-Sided Platforms and E-Commerce Businesses took effect, and in July the TCCT established a digital platform subcommittee to regulate and prevent unfair trade practices in digital platform businesses. This activity followed a TCCT market report on e-marketplace businesses in September 2025. Modern trade and credit terms: This sector was the focus of the TCCT’s 2019 Guidelines on Unfair Trade Practices between Wholesale and Retail Operators and Manufacturers or Suppliers (widely known as the “Modern Trade Guidelines”) , as well as its 2021 Guidelines on Unfair Trade Practices regarding the Credit Terms under which Small and Medium Enterprises (SMEs) Sell Products or Services to a Purchaser (also known as the “Credit Term Guidelines”), which were amended the following year. Ride-hailing and on-demand delivery (including food delivery and quick commerce): The TCCT published the Guidelines on

On July 8, 2026, Thailand enacted a new law significantly expanding the framework for government service delivery and licensing facilitation. The Facilitation of Licensing and Public Services Consideration Act B.E. 2569 (2026) (Facilitation Act 2026) replaces and expands the framework of governmental services under the Facilitation of Official Licensing Consideration Act B.E. 2558 (2015) (Facilitation Act 2015) and broadens its scope to cover public services, administrative processes, and public benefits. The Facilitation Act 2026 aims to modernize government services by promoting e-filing, reducing administrative burdens and repeated document requests, and improving predictability. For businesses, this should ease compliance and shorten approval timelines, subject to implementing regulations and agency readiness. Public Services Facilitation Scope The Facilitation Act 2015 applied mainly to permissions, registrations, and notifications required before conducting activities that require licenses, certificates, permits, approvals, or registrations. The Facilitation Act 2026 broadens this framework to include public services and other benefits, such as welfare, subsidies, and grants, provided to Thai citizens, expanding government agencies’ responsibilities beyond licensing facilitation into a wider administrative-service framework. It also introduces a broader definition of “government agency” to include central, regional, and local government bodies, state enterprises, public organizations, and other state entities. Licensing Changes The Facilitation Act 2026 introduces a “super license” (termed a “main license” under the act) that exempts the holder from obtaining multiple related or ancillary licenses issued by different government agencies. Obtaining a super license deems the licensee to have automatically obtained the related “sublicenses” required to conduct the relevant activities. The cabinet will designate eligible activities by royal decree. The act also introduces an expedited licensing option, allowing applicants to pay an additional fee to fast-track their applications in urgent cases. Expedited processing must not interfere with standard application timelines. The criteria, procedures, conditions, and fees for expedited licensing

Vietnam has taken a significant step in regulating its e-commerce sector with the issuance of a new decree guiding the country’s recently enacted Law on E-Commerce. Decree No. 248/2026/ND-CP, issued on June 30, 2026, and taking effect the following day, addresses mandatory platform policies, registration requirements for offshore platforms, additional obligations on platform operators, and market access conditions for foreign investors. Mandatory Policy Contents The decree sets out detailed guidance on the required contents of various platform policies, covering pricing, payment, display priority, livestream sales, delivery, returns, method of service provision, and service termination and refunds. Clarification of Obligations for Platform Operators The decree provides clarification of the obligations applicable to platform operators. Notably, intermediary e-commerce platform operators with online ordering functions must: Collect specific information to implement electronic identity verification of sellers; Cooperate with regulators by reporting online through the state e-commerce management system and by blocking, suspending, or removing content upon request of a competent authority; Maintain a mechanism to store contract data, including price, product or service information, and parties’ information, for at least three years from the date of contract conclusion; and If qualifying as a “large digital platform” under consumer protection law, maintain an online system for receiving and handling complaints and requests, and comply with enhanced content-removal requirements. Registration Requirements for Offshore Platforms Offshore e-commerce platforms, whether direct-sales, intermediary, social-network-based, or integrated, that conduct e-commerce activity in Vietnam must register with the Ministry of Industry and Trade if the platform: Allows Vietnamese-language selection; Uses a “.vn” domain; or Reaches 100,000 or more transactions with Vietnam-based buyers within a calendar year. Notably, the registration requirement now captures not only traditional intermediary platforms, but also direct-sales platforms. Foreign Investment Conditions Foreign investors holding a controlling interest in an intermediary e-commerce platform, a social media platform

On July 7, 2026, the Trade Competition Commission of Thailand (TCCT) issued a press release announcing the establishment of two new subcommittees designed to intensify oversight of digital platforms and modern trade businesses. The formation of the digital platform subcommittee marks a significant escalation in competition enforcement following the TCCT’s Guidelines on Multi-Sided Platforms and E-Commerce Businesses, which took effect on March 25, 2026. Platform operators, sellers, and related service providers should expect heightened regulatory scrutiny and potential investigations into practices already flagged under the March guidelines. Two Dedicated Enforcement Bodies The first new body is the digital platform subcommittee—formally the Subcommittee on Supervision, Monitoring, and Prevention of Trade Conduct in Digital Platform Business. It is tasked with driving intensive oversight of digital platform businesses. It will coordinate with government agencies, the private sector, business operators, and other relevant stakeholders to supervise and prevent trade conduct that may affect competition, and to promote free and fair competition in the digital platform sector. The subcommittee will be composed of TCCT members and representatives from the Department of Internal Trade. The second body—the Subcommittee on Determining Guidelines and Action Plans Concerning Competition Conditions in Modern Wholesale and Retail Business—will study, analyze, and monitor market structure in modern wholesale and retail businesses, compile databases to analyze retail business concentration, assess impacts on small-scale operators, and propose supervisory measures for the retail sector. TCCT members will serve on the subcommittee alongside experts from government and private organizations, including the Office of Industrial Economics, the Office of Small and Medium Enterprises Promotion, the Thai SME Federation, and the Thai SME Council. Operational Impact for Industry Participants These subcommittees provide the TCCT with a focused mechanism to investigate various trade practices deemed unfair, and the TCCT has authority under the Trade Competition Act to issue cease-and-desist
