Thailand’s Competition Law: What to Watch in the Year Ahead

Subscribe to Updates

The past year has been an important one for the Trade Competition Commission of Thailand (TCCT). With a right combination of commissioners bringing expertise in competition law, investigations, administrative procedures, court processes, and sector-focused industries, the regulator has pushed forward with stronger enforcement efforts and closer cooperation with both domestic and international stakeholders.

In 2025 the TCCT participated in major international initiatives—including peer reviews conducted by the OECD and ASEAN. These efforts reflect Thailand’s ongoing ambition to elevate its competition law framework to meet international expectations and build trust among global communities.

There was also significant momentum around potential amendments to the Trade Competition Act (TCA). Political parties, the TCCT, the private sector, and civil society all agreed that the 2017 law could benefit from clearer rules and more effective enforcement tools. Although a draft amendment passed an initial reading and moved to a subcommittee for revision, the process stalled following the dissolution of Parliament.

At the same time, the TCCT invested heavily in strengthening its own internal capabilities. It expanded collaborations with organizations such as the OECD, ASEAN authorities, the EU, and counterparts in Japan and Australia.

The TCCT also published sector-specific market studies, including on digital platforms and e‑marketplaces and on cold‑rolled steel. The regulator also shared draft guidelines aimed at regulating online platforms—although these have not yet been finalized.

What’s Next for the TCCT?

Looking ahead, the TCCT is set to keep building on the momentum it has created and be a more active, transparent, and practical regulator. It is likely to become even more visible in the public sphere as it steps up efforts to raise awareness about competition law, especially among businesses that may not traditionally follow or be familiar with such regulatory developments. Digital markets, including e‑commerce and online marketplaces, will remain a particular area of focus as the TCCT continues to monitor the fast‑evolving landscape.

The TCCT is also working to refine how it enforces the law. Following recent peer reviews by the OECD and ASEAN, the regulator intends to issue more detailed and better‑structured decisions. This shift is aimed at giving businesses clearer explanations of the legal and economic reasoning behind the TCCT’s findings. Over time, these decisions should help companies better understand how the rules are applied in practice and contribute to broader legal and academic discussions in the field.

Internally, the TCCT is reviewing the full suite of legal tools available under the TCA. The goal is to ensure these mechanisms, such as injunctions and settlements by fines, are used more efficiently and consistently. To support this, the TCCT is expected to introduce new rules or guidelines on fine levels and calculation methods. If implemented, these standards would bring Thailand’s penalty system closer to international practices, including those used in the US and EU.

New Draft Rules on Consultation for Advance Decisions

On February 4, 2026, the TCCT released a draft notification outlining updated criteria and procedures for requesting advance decisions under section 59 of the TCA. Section 59 allows businesses to proactively ask the TCCT to review whether a planned activity, such as a business strategy, marketing program, or other proposed conduct, could potentially violate the TCA.

For many businesses, this preliminary consultation tool is an effective way to reduce regulatory and competition‑law risks. Businesses that have taken advantage of this process have found that obtaining an advance decision can provide meaningful legal certainty, as the decision is binding once issued.

Business Outlook

Throughout the coming year, businesses operating in Thailand would be well-advised to stay closely informed about the TCCT’s enforcement practices and forthcoming guidelines. Proactive engagement with competition authorities, regular compliance reviews, and timely consultation on planned initiatives can help mitigate legal risks and capitalize on new opportunities as the regulatory landscape continues to mature. As 2026 unfolds, companies that prioritize adaptability and a forward-thinking approach to competition law will be best positioned to navigate the shifting environment with confidence and clarity.

On February 4, 2026, the Trade Competition Commission of Thailand (TCCT) released a draft notification outlining updated criteria and procedures for requesting advance decisions under section 59 of the Trade Competition Act (TCA). This draft is now open for public comment through the TCCT website until March 5, 2026. Section 59 of the TCA lets businesses proactively ask the TCCT to review whether a planned activity, such as a business strategy, marketing program, or other proposed conduct, could potentially violate the TCA. The major limitation is that this mechanism cannot be used for merger‑control matters. The new draft aims to make the process more accessible and user‑friendly. Key updates include allowing for electronic submission of requests and establishing a shorter notification timeframe, requiring the TCCT to explain any delay to the 60‑day review period within 7 days instead of the previous 15 days. For many businesses, this preliminary consultation tool is an effective way to reduce regulatory and competition‑law risks. Businesses that have taken advantage of this process have found that obtaining an advance decision can provide meaningful legal certainty, as the decision is binding once issued.

Spurred by global geopolitics and Canada’s Indo-Pacific Strategy, which aims to forge deeper ties with ASEAN, Canadian companies have been showing growing interest in Thailand and Southeast Asia in recent years. To understand the opportunities offered by the region, we sat down with Andrew Stoutley, a Toronto native and the chief operating officer of Tilleke & Gibbins, a leading Southeast Asian regional law firm with over 130 years of history in Thailand. Q: Why are Canadian companies looking at Thailand and Southeast Asia right now? A: Two reasons stand out. First, diversification has moved up the agenda. Many Canadian companies want options outside North America due to tariff volatility and policy uncertainty in the United States, as well as questions around the next Canada–United States–Mexico Agreement mandatory joint review. At the same time, the shift of global production from China to Southeast Asia is accelerating, driven by rising costs, geopolitics, and the need to avoid overreliance on a single market. As a result, Canadian companies are looking for a second production base or a regional hub, and Thailand and its neighbors are natural choices given their manufacturing depth, location, and established supply chains. Second, Canada’s own efforts in the region are gaining traction. The Indo-Pacific Strategy has led to more on-the-ground support, including larger trade missions, upgraded diplomatic posts, and new financing options. Export Development Canada (EDC) now has a presence in Bangkok, giving Canadian companies a direct line to financing and insurance in Thailand. There’s also steady progress on trade frameworks like the recently signed Canada–Indonesia Comprehensive Economic Partnership Agreement (which will come into effect pending domestic procedures), ongoing negotiations of a Canada–ASEAN FTA, and the exciting announcement about the launch of negotiations of a Canada–Thailand FTA. Together, these developments have the potential to make it much easier

Myanmar’s Ministry of Finance and Revenue has introduced new procedures allowing companies to temporarily export raw materials and semifinished goods for overseas processing before reimporting the finished products for domestic sale. The procedures are detailed in Notification No. 143/2025, which was issued on December 23, 2025, taking effect on February 1, 2026. The new procedures define outward processing as the temporary export of domestically circulating or manufactured goods for manufacturing, processing, treatment, or repair abroad, followed by reimportation. Core elements include the temporary export of the goods, the continuity and identifiability of the exported and reimported items, and the assessment of duties based on the value added abroad. Upon reimportation, customs duty, commercial tax, specific goods tax, and advance income tax are applied only to the foreign value added, rather than to the full value of the goods. No advance income tax applies at the time of export. Before these procedures, Myanmar lacked a unified outward processing system. The closest existing practice was the “repair and return” mechanism, used for goods such as machinery parts that required repair abroad. The definition covers a broader range of operations than simple repair. Eligible Goods and Shipment Points Outward processing is permitted only for goods that satisfy specific eligibility criteria. The scheme expressly excludes: Goods that are prohibited from export or import Goods that can be processed domestically within Myanmar Precious stones Goods that would lose their essential characteristics after processing Export and reimport activities related to outward processing must be conducted through designated ports, airports, or dry ports located within Yangon Region. Eligible Companies Only companies that are legally registered in Myanmar and authorized as exporters or importers—specifically, businesses holding a valid export/import registration certificate—are eligible to engage in outward processing activities. The Myanmar Customs Department serves as the governing authority

On December 31, 2025, Myanmar’s Department of Trade introduced new rules for import and export license applications. The rules were issued in Announcement No. 4/2025, which took effect on January 1, 2026. Under the announcement, all applications for licenses must now be submitted and approved through the online Myanmar TradeNet 2.0 system. The announcement sets a maximum review period of 180 days for each application. If approval is not granted within this period, the application will be automatically canceled by the system. In addition, companies may submit only one application per calendar month for goods of the same type (same HS code), and only one license will be approved. Businesses involved in importing goods should review their planning and ensure compliance with the new restrictions.
