On May 21, 2025, the Trade Competition Commission of Thailand (TCCT) published a press release signaling heightened regulation of digital platforms in response to the influx of products from foreign countries being sold in Thailand via e-commerce platforms. In recent years, the rapid expansion of cross-border multi-sided e-commerce platforms has unlocked unprecedented growth, but it has also flooded Thailand’s digital marketplaces with low-cost imports sold by unregulated foreign vendors via these platforms, unfairly undercutting local merchants’ market share and exposing consumers to uneven product quality. According to the press release, the TCCT announced progress on drafting new guidelines on unfair trade practices, monopolistic conduct, and competition restraint by multi-sided e-commerce platforms at a recent meeting of the Management Committee for Addressing Issues of Foreign Goods and Businesses Violating Laws. This regulatory push is part of a broader governmental effort to tackle issues stemming from the foregoing that create uneven playing fields and undermine consumer welfare. The draft guidelines are designed to regulate platform operators and their complex and multidimensional trade relations that cause network effects and distort competition. The forthcoming guidelines, to be issued under the Trade Competition Act B.E. 2560 (2017), will undergo public consultation to ensure platform operators, the public, and other stakeholders will have an opportunity to provide input before they are finalized and enforced. The guidelines are seen as an important priority, with the minister of commerce urging swift implementation of the measures to achieve the government’s objectives. In addition to the legislative advancement, one of the TCCT commissioners has been appointed to advise a subcommittee on preventing nominee arrangements by foreign investors and a subcommittee dedicated to promoting Thai SMEs and eliminating poor-quality imports. The appointee will also support the nationwide task force against illegal foreign products in overseeing proactive field operations and comprehensive

On May 2, 2025, the Trade Competition Commission of Thailand (TCCT), in cooperation with the OECD, held a conference to discuss the results of the OECD Peer Review of Thailand’s competition law and policy. This review, conducted under the second phase of the OECD-Thailand Country Program, marks a significant milestone in Thailand’s ongoing institutional reform. Tilleke & Gibbins’ trade competition experts were invited to participate in both the program and the conference. The OECD Peer Review aimed to assess the current state of Thailand’s legal and regulatory environment surrounding competition law and policies, pinpoint strengths and weaknesses, and offer recommendations on potential future development. This article highlights the review’s key findings and recommendations, and their implications for businesses operating in Thailand. Institutional Framework: Room for Improvement Competition law in Thailand has undergone significant transformation, particularly since the enactment of the Trade Competition Act B.E. 2560 (2017) (TCA). This landmark legislation aimed to revolutionize the competition regime, notably by amending important legal provisions to enhance public enforcement capabilities and establishing the TCCT as an independent authority separate from government ministries, endowed with its own budget and powers to enforce competition law across key areas: anticompetitive agreements, abuse of dominant market positions, merger control, and unfair trade practices. The goal was to create a more efficient, flexible, and independent agency and to prevent political intervention. However, the OECD Peer Review points out a major impediment. The TCCT faces considerable budget and human resource constraints, which may impact its enforcement capacity. Its budget is comparatively low by international and regional standards, and only a fraction of its staff is dedicated to core competition enforcement (merger control and anticompetitive behavior). Furthermore, there is room for the TCCT to continue its improvements in expertise and efficiency—areas the TCCT has been attempting to shore up

Importers of goods into Thailand can often reduce confusion and preempt customs disputes by proactively seeking an advance ruling on customs classification. This process, which has been possible since Customs Department Announcement No. 17/2561 in 2018, allows importers to request a ruling from Thailand’s Customs Department on the tariff classification of goods prior to importation. Obtaining an advance ruling significantly reduces risks and uncertainties in business operations. Benefits of Requesting an Advance Ruling Some of the benefits of requesting an advance ruling include: Certainty and clarity: Receiving an advance ruling helps importers know the correct tariff classification before importing, aiding in confident business planning and decision-making.
