The Development of Trade Competition Legislation in Thailand

Informed Counsel

The competition law regime in Thailand has recently undergone a number of significant changes and promising developments, starting with the implementation of the Trade Competition Act B.E. 2560 (2017) (TCA) on October 5, 2017.

In 2018, the Trade Competition Commission (TCC) passed major guidelines that clarified the criteria for considering fundamental offenses under the TCA (i.e., abuse of dominant position, hardcore cartels, non-hardcore cartels, and unfair trade practices), as well as the merger control regime under the TCA.

More promising still, the TCC proved to be a very active organization in 2019, issuing subordinate legislation and actively pursuing enforcement of the TCA. In August 2019, the TCC carried out its first enforcement in respect to three competition cases that were investigated by the previous commission. Summaries of these three precedent cases are provided below.

Abusing a Dominant Position in the Market

The first case, which occurred between October 2011 and July 2012, involved an energy drink manufacturer that had a dominant position in the energy drink market. The manufacturer was alleged to have prohibited its distributors from selling the products of its competitors. The TCC ruled that the energy drink manufacturer committed an offense by abusing its dominance, in contravention of the Trade Competition Act B.E. 2542 (1999)—the legislation that the TCA replaced. The TCC imposed aggregate fines of approximately THB 12 million, consisting of separate THB 6 million fines on both the company and the company’s director.

Unfair Trade Practices: Buyers

A case involving two buyers of agricultural products occurred during the enforcement of the 2017 version of the TCA. The TCC ruled that the buyers had engaged in unfair trade practices by threatening other prospective buyers and prohibiting them from purchasing agricultural products from sellers based in the same area as the offenders. The TCC imposed a THB 25,000 fine on the offenders, initially calculated as 10% of the offenders’ total turnover during the year of the offense (the total turnover was THB 500,000) and further reduced by half due to the offenders’ cooperation and in light of it being their first offense.

Unfair Trade Practices: Retail Business Operator

A retail-related case also occurred under the 1999 act. In 2011, a hypermarket operator launched a promotion by which customers could exchange a competitor’s coupon with its own coupon for double the value. The hypermarket operator was found guilty of engaging in unfair trade practices under section 29 of the 1999 act (now section 57  of the TCA) during January, July, and August of 2011. However, the TCC did not impose a criminal fine on the hypermarket operator, as the 1999 act had already been repealed when the TCC’s decision was made. The TCC also could not impose an administrative fine under section 57 of the current TCA, because this would have been contrary to the principle of non-retroactivity.

Subordinate TCA Legislation Issued in 2019

In 2019, the TCC issued more sector-specific guidelines, which aimed to prevent wholesalers, retailers, and franchisors from engaging in unfair trade practices with their business partners. The most recent of these was a notification that focused specifically on franchise businesses; this is covered in detail in another article in this issue of Informed Counsel.

Some months prior to this was a notification that dealt with determination of unfair trade practices in wholesale and retail businesses. The Notification Regarding the Guidelines for the Consideration of Unfair Trade Practices in a Wholesale and Retail Business came into force on July 20, 2019. It sets out the criteria for the consideration of unfair trade practices and provides a list of the types of conduct that wholesalers and retailers (e.g., hypermarkets, department stores, supermarkets, convenience stores, etc.) are prohibited from undertaking in their dealings with manufacturers or distributors (including importers). These types of prohibited conduct can be further classified into eight categories:

  • Unfairly fixing a low purchasing price from the manufacturer or distributor (including forcing the manufacturer or distributor to provide a discount for products already delivered);
  • Unfairly demanding economic benefits from the manufacturer or distributor;
  • Unfairly returning the purchased goods without a justifiable reason;
  • Unfairly setting contractual conditions in the consignment agreement;
  • Unfairly forcing the manufacturer or distributor to purchase goods or services without a justifiable reason;
  • Unfairly assigning duties to the personnel of the manufacturer or distributor without prior agreement or the consent of the manufacturer or distributor;
  • Unfairly refusing to accept products that are specifically ordered or made for the wholesaler or retailer (e.g., private brand, house brand); and
  • Other unfair trade practices that may cause damage to a manufacturer or distributor, such as delaying payment for the purchase of goods, refusal to deal, or delisting of stock.

Going Forward

In 2020, the TCC will focus on releasing more guidelines for specific regulated sectors such as the telecommunications, financial, insurance, and energy sectors. The TCC is also in the process of drafting additional guidelines for the consideration of mergers under the TCA. In terms of enforcement, the TCC has revealed that there are around 40–50 cases relating to offenses under the TCA that remain under investigation. As the TCC continues to actively shape the evolution of competition law in Thailand, it is anticipated that the Thai competition law regime will see more significant developments and positive changes in the years to come.

On August 6, 2025, Myanmar’s National Defence and Security Council (NDSC) issued Order No. 20/2025, announcing a change in the composition of the country’s Foreign Exchange Supervisory Committee (FESC). The prime minister has been appointed committee chair of the FESC, and five other individuals were appointed to the committee. The order took immediate effect. Originally established in April 2022, the FESC is responsible for approving foreign currency conversion, granting exemptions to foreign exchange restrictions, and permitting overseas transfers of foreign currency. The FESC supervises the flow of foreign currencies for domestic and foreign investment, manufacturing, exports and imports, and service businesses (including education- and health-related initiatives). The FESC is specifically responsible for considering and approving the use of foreign currency for the following: Importing machinery, vehicles, equipment, and raw materials essential for foreign investment and manufacturing projects; Importing fuel, medicine, cooking oil, fertilizer, insecticide, and construction materials not readily available on the domestic market; Covering Myanmar citizens’ needs abroad, such as medical treatment, education, or religious activities; Facilitating imports of general goods, loan repayments, interest payments to foreign lenders, service payments, and profit repatriation from investments; and Importing luxury products, including brand-name goods, jewelry, sports cars, and watches.

For companies and individuals doing business in Vietnam, a common question is whether electronic signatures (e-signatures) are legally recognized under Vietnamese law. This matter is governed by Law No. 20/2023/QH15 on Electronic Transactions issued on June 22, 2023 (ETL 2023) and its guiding legal documents such as Decree No. 23/2025/ND-CP dated February 21, 2025, and Circular 06/2024/TT-BTTTT dated July 1, 2024 (Circular 06). Recognition of Validity of E-signatures in Vietnam As a general principle, the ETL 2023 confirms that an e-signature cannot be denied legal validity solely due to its electronic form. The law categorizes e-signatures into three types: Type 1: Specialized e-signatures for organizations Type 2: Public digital signatures for individuals and organizations Type 3: Specialized digital signatures for government agencies Among these types, only secure specialized e-signatures (a secure e-signature of type 1) and digital signatures (type 2) are explicitly granted the same legal validity as handwritten (wet) signatures. This distinction is particularly important in legal disputes and for transactions with government agencies. (For more details, please refer to our previous article.) Domestic e-signatures A domestic organization can choose to use secure specialized e-signatures (type 1) and/or digital signatures (type 2) while a Vietnam-based individual can choose digital signatures (type 2) for their transactions—particularly for those involving government agencies and transactions of high value and complexity which require stronger legal protection. Specialized e-signatures (type 1) can be created by the organizations themselves, and additionally must be “secure” to be explicitly recognized as having the same legal validity as handwritten signatures. For clarity, “secure” specialized e-signatures are those certified (granted a safety certificate) by the Ministry of Science and Technology (MST). (This was formerly the responsibility of the Ministry of Information and Communications, which was merged with MST under Vietnam’s 2025 administrative restructuring.) Digital signatures (type 2) are

On July 3, 2025, the Trade Competition Commission of Thailand (TCCT) officially announced an invitation for stakeholders to participate in a public survey to gather feedback on the flexibility and appropriateness of credit terms across different business sectors for goods and services. The TCCT initially introduced guidelines on unfair trade practices related to credit terms applicable to small and medium-sized enterprises (SMEs) in 2021, with amendments following in 2022. The guidelines have had a wide impact, as businesses have had to adapt their payment procedures and practices, particularly those for dealing with SMEs, to comply with the guidelines. The TCCT is now seeking comprehensive feedback from businesses and other stakeholders to evaluate the effectiveness and practicality of these guidelines. The collected responses may potentially lead to future amendments aimed at enhancing fairness and efficiency in business transactions. To summarize the core principles, the guidelines aim to improve the liquidity and cash flow of SMEs, stipulating payment terms of: Within 30 days for agricultural products or primary agricultural processing involving non-complex production. Within 45 days for trade, manufacturing, and service sectors. The guidelines also identify practices deemed unfair, including: Unjustified delays in payment beyond agreed credit terms. Changes to credit terms or contractual conditions without at least 60 days’ advance notice. Other unfair conduct or credit term conditions that impose excessive burdens on an SME. Interested stakeholders are encouraged to submit their feedback through the TCCT’s online survey form available via their official public media channels. The survey is open for responses until July 20, 2025.

On January 9, 2025, the Lao official gazette published the newly amended Decision on Trade Inspection Implementation No. 0019/MOIC, dated January 6, 2025. This decision aims to establish principles and rules for trade officers to inspect, fine, and take measures against violators of trade laws and their related regulations on business competition, business operations, and intellectual property rights to protect consumers and business operators in Laos. Changes in Trade Inspection Procedures Previously, trade inspection officers, operating independently under the central Ministry of Industry and Commerce (MOIC) or the provincial-level Department of Industry and Commerce (DOIC), were responsible for administrative raid actions focusing exclusively on intellectual property issues. However, following the enactment of Decision No. 0019/MOIC, trade inspection officers will now be grouped into the Trade Officers Unit, which will also include business competition officers and consumer protection officers. This unit will conduct and participate in raids, considering not only intellectual property laws but also competition and consumer protection laws when imposing penalties on infringers. Trade Inspection Authority Levels Trade inspection implementation is overseen by authorities at three levels: Central level: Department of Business Competition and Trade Inspection, MOIC. The MOIC handles trade inspection work covering all provinces in Laos. Provincial level: DOIC offices in provinces and Vientiane handle trade inspections covering two or more districts. District level: Office of the Industry and Commerce offices in districts. Violations Individuals, legal entities, and organizations violating the newly amended trade inspection decision, the Decree on Trade Inspection, or other related regulations will be educated about the issue, warned, disciplined (for government servants), fined, subject to compensation for damage incurred, or punished by the relevant laws, depending on the gravity of the violation. Trade Violations Violations of trade laws and regulations concerning business operations will result in fines and additional measures. Examples include:
