Thailand’s Free Trade Agreements: Minimizing Costs for Businesses

Tilleke & Gibbins

Free trade agreements (FTAs) provide a range of benefits to businesses. FTAs, which are agreed upon between two or more countries, allow companies in those countries to trade in certain goods with reduced or eliminated tariff rates. They can greatly reduce costs for businesses, and in turn, this allows companies to allocate more resources to other business functions such as research and development, marketing, and so on.

This article provides an overview of Thailand’s FTAs and the types of goods they apply to. In particular, the article discusses how businesses should operate in countries with FTAs.

Thailand’s FTAs

Under the laws and regulations of the World Trade Organization, Thailand has six separate FTAs with Australia, Chile, China, Japan, New Zealand, and Peru. As an ASEAN member country, Thailand also belongs to various regional FTAs, including an FTA among ASEAN member countries, and separate FTAs between ASEAN member countries and Australia, China, India, Japan, Korea, New Zealand.

ASEAN member countries are currently negotiating several FTAs and Regional Comprehensive Economic Partnerships to further reduce trading costs and encourage trade within ASEAN and between ASEAN and other countries.

FTAs between individual countries and FTAs that affect whole regions can overlap. If a company is operating in a country where multiple FTAs apply, and it is trading in certain goods designated in the FTAs, the company can select the most favorable tariff rate.

Requirements for the Application of FTA Tariff Rates

FTA tariff rates are applicable if goods which are traded between countries that belong to an FTA satisfy the following requirements:

The goods are covered by the FTA. FTA tariff rates can apply to any types of goods, as long as the goods are specifically included in an FTA. The goods are specified by a Harmonized System code—a widely recognized code to classify goods. Countries have discretion in classifying goods under Harmonized System codes, and therefore, it is common for the same good to have different classifications.

To determine whether an FTA applies to certain goods, a request for information can be made to Customs in the importing country or at the National Trade Repository of an ASEAN member country. The National Trade Repository has an informative database containing valuable regulatory information ranging from Harmonized System codes for goods to documents required when importing a product. Every ASEAN member country contributes to this database, which has increased transparency and improved the time it takes to search for laws and regulations. It can be accessed at the ASEAN Trade Repository website.

The goods originate from the exporting country. FTAs focus on the trade of goods that originate, or largely originate, from the exporting country. The specific goods mentioned in the FTA must be “Originating Goods,” a requirement which can be fulfilled in a number of ways.

To qualify as Originating Goods, a good can either be wholly obtained or produced from the exporting country, or produced exclusively from materials from the exporting country. In addition, a good can qualify if it is wholly or partially made of foreign materials, and it adheres to product-specific rules that are found in most FTAs, per any of the following:

  • The end product has a different Harmonized System code than the foreign materials it is made of. The agreement specifies what part of the code must be different.
  • The good has value added in the exporting country. FTAs normally have provisions on how to calculate this and what thresholds need to be met.
  • The good has gone through a specific process stipulated in the FTA.

These definitions can be quite technical, and they can vary depending on the FTA. If a company is operating in a country with multiple FTAs, it is important to examine these definitions closely to see how trading costs may be reduced.

FTAs in Practice

Using an FTA for a company’s benefit can be illustrated with a practical example. Take a car factory in Thailand. The factory assembles a number of parts to form a final product, a car. In considering where to obtain the individual parts, FTAs are factored into the equation. Cherry picking the most advantageous FTA for each individual part can almost completely eliminate tariff costs.

The company could import exhaust pipes from Cambodia, which are covered by a regional ASEAN FTA that completely eliminates import tariffs to Thailand. Wheels are not covered by any FTAs, and so the company could purchase these locally to avoid importing costs. Any car electronics could be imported from Peru, as there is a Thailand-Peru FTA that greatly reduces tariffs for electronics imported from Peru.

Once all of these parts are assembled into a car, they constitute a new product and consequently the Harmonization Code changes. The car would qualify as an Originating Good from Thailand, under the requirements mentioned above. An FTA applicable to cars can now be used to export the car with limited or eliminated tariff costs from Thailand.

Reducing Costs Through FTAs

Companies should strive to operate their business in the most cost-effective way. Deciding on which countries parts and final products will be manufactured in, how to procure parts and materials, and how to distribute final products can have a lot of influence on the costs incurred by businesses. FTAs can go a long way toward reducing costs and maintaining a competitive edge.

Thailand’s Board of Investment (BOI) now requires data center projects to demonstrate measurable benefits for local workforce development, R&D, SME capability, and domestic supply chains to qualify for corporate income tax (CIT) exemptions. BOI Notification No. Por. 3/2569, issued on February 6, 2026, updates the requirements for projects seeking promotion under BOI category 8.2.1 (data centers). All data center projects must now submit and implement plans covering development of Thai human resources and domestic supply chain support before benefiting from any CIT exemption. Human Resources Development Plan The BOI seeks to promote local talent development beyond basic training. Plans must include the following elements: Training for data center design, construction, and operations targeting vocational students, engineering and ICT undergraduates and postgraduates, and energy and building personnel in Thailand. Joint curricula with Thai universities and technical institutes. Collaborative R&D with Thai nationals or institutions in areas including AI, resource allocation, high-performance computing, and data center hardware and systems. Thai SME upskilling in electrical and energy systems and IT services. Domestic Supply Chain Support Plan Plans must demonstrate knowledge transfer in design, construction, cooling, security, and power and water management. Projects must also include usage or installation of domestically manufactured equipment or engage specialist domestic entities. Criteria for BOI Evaluation The BOI will assess data center operators’ eligibility for CIT incentives based on two criteria: Scale requirement: Training and joint-curriculum initiatives must reach a total participants equal to at least 10 times the project headcount and run for the duration of the CIT incentive. If this threshold is not met, the applicant must also implement continuous R&D or SME skills-development plans throughout the incentive period. Substantiality test: Supply-chain plans must be substantive, meet industry standards, and show measurable development of the domestic digital and data center supply base. To ensure compliance,

Thailand’s Securities and Exchange Commission (SEC) has overhauled its approach to related-party transactions (RPTs) by issuing new rules that simplify approval processes while expanding oversight. Capital Market Supervisory Board Notification No. TorJor. 46/2568 will replace the longstanding Notification No. TorJor. 21/2551, which has governed RPT compliance for over a decade. The new regulation takes effect on July 1, 2026. Any RPT matters approved by a company’s board of directors or approved for shareholders’ approval before that date remain subject to Notification No. TorJor. 21/2551. The new RPT rules will introduce significant changes that market participants should carefully consider. Consolidated Definitions Under the previous framework, key definitions relevant to RPT compliance were dispersed across multiple sources, including SEC notifications, Stock Exchange of Thailand (SET) regulations, and provisions of the Securities and Exchange Act (before amendments). The new regulation consolidates these definitions into a single notification. Concepts such as “related party” and “connected person,” as well as relevant transaction categories, are now more systematically organized and written in greater detail. The SET has yet to issue corresponding regulations, which should include more detailed related disclosure requirements. Unified Threshold and Mandatory Board Approval The most significant change under the new regulation is the elimination of the multitiered approval framework based on transaction type. Instead of various categories, transactions are now classified as either (1) financial assistance provided to related persons, or (2) other RPTs in order to determine the level of corporate approvals and disclosures for each transaction size in these categories, but the concept remains the same. Under the previous regulation, RPTs were divided into small, medium, and large transactions, with differing approval requirements. The new regulation effectively merges the small and medium categories. As a result, all RPTs must now be approved by the board of directors as a baseline

Thailand’s Securities and Exchange Commission (SEC) has issued a new regulation on material transactions (MTs) to govern asset acquisitions and disposals by listed companies and their subsidiaries. The new notification on MT criteria (No. TorJor. 45/2568) from the Capital Market Supervisory Board replaces the long-standing notification (No. TorJor. 20/2551) that has governed such matters. The SEC has also introduced parallel amendments to the country’s related-party transaction rules. The new regulation will take effect on July 1, 2026. Any MT matters approved by a company’s board of directors for shareholders’ approval before that date remain subject to Notification No. TorJor. 20/2551. Following that date, the new MT rules will introduce several significant changes that market participants should carefully consider. Expanded Scope of Material Transactions One of the key changes under the new regulation is the expansion of the definition of MTs, which now expressly covers financial assistance and certain lease and business lease arrangements that are not in the ordinary course of business of the listed company or its subsidiaries. For financial assistance, this includes lending, granting credit, providing guarantees, or entering into any arrangement that increases the company’s financial obligations, particularly where the recipient is facing liquidity issues or unable to repay debts. Other forms of financial support also fall within scope. However, whether the provision of collateral for others qualifies as an MT remains somewhat unclear, since no disposal of assets occurs for the provider of collateral. This issue remains to be carefully considered. For lease-related transactions, the MT rules now specifically include the lease or hire-purchase of all or part of a business or assets operated by or belonging to a listed company or its subsidiaries. New Exemptions The new regulation introduces clearer exemptions for transactions between a listed company and its subsidiaries or among subsidiaries, which
