Anti-Dumping Measures: Easing the Transition to Free Trade

Bangkok Post, Corporate Counsellor Column

Many businesses in ASEAN countries continue to adjust to the changes brought about by the elimination of import duties, in the context of both the ASEAN Economic Community and other bilateral and multilateral free trade agreements. While reductions in barriers to trade—tariff or non-tariff—can open foreign markets to domestic producers, they also bring additional competition for domestic producers in their home markets.

In a world without barriers to trade, the idea is that each country would produce those goods in which it has a comparative advantage. While the economic efficiency this brings benefits everyone in the long term, the transitions are not always smooth. To address problems caused by dumping, countries can assess anti-dumping duties, subject to certain regulations.

Though there are some regional and country-specific differences, anti-dumping regimes are quite standardized across borders. This is largely because the Anti-Dumping Agreement of the World Trade Organization governs application of anti-dumping measures by WTO member countries. In Thailand, the relevant law is the Anti-Dumping and Subsidized Imports Act B.E. 2542 (1999), which replaced what had previously been contained in regulatory notifications issued by the Ministry of Commerce, dating as early as 1991.

Simply put, a product is “dumped” when it is exported to another country for sale at a price below the normal value of that product, or a like product, in the exporting country. However, for dumping to be actionable, it is also necessary to prove that there was injury to domestic industry in the country to which the dumped goods were exported, and that such injury was caused by the dumping. It can be challenging to prove all three elements.

Dumping, Injury, and Causation

For a country’s regulator to determine whether dumping is occurring, the export price of the allegedly dumped goods must be compared to their normal value. The WTO agreement provides three options, the most preferred one being to determine normal value on the basis of the exporter’s price in the exporter’s home market. There is also some allowance to use similar goods if the exact good is not sold in the home market.

However, in some cases, the product of interest might not be sold in sufficient quantities in the exporter’s domestic market, making this method unviable. In this case, pricing in a third country’s market can be used. If that is not viable, the third option is to determine normal value by the constructed value method, which can be used for investigations of exports from countries that are not market economies.

In making the comparison between export price and normal value, there are many prescribed adjustments to make the comparison more indicative of real differences; these include, for example, those to account for product differences and level of trade.

The next element is injury to domestic industry. This can consist of present injury, threat of injury, or retardation in the establishment of domestic industry.

Finally, the last element is causation. The purpose here is to determine whether the dumping actually caused the injury, or whether it was caused by some other factor.

Investigations

To initiate an anti-dumping investigation, a request would be made by domestic industry to the relevant domestic regulator (in Thailand, the Department of Foreign Trade at the Ministry of Commerce). For the request to be valid, at least 25% of the domestic industry must be represented, and opposition must be less than 25% of the domestic market. Often, a single producer has sufficient production to have standing to request the investigation independently. Otherwise, multiple producers within an industry would jointly request the investigation.

In applying for an investigation, domestic producers seek to build a prima facie case of dumping, injury, and causation, to make it more likely that the action will proceed. Assuming the investigation proceeds, accused foreign producers are asked to complete questionnaires about their pricing, costs, and related matters.

On the basis of these questionnaires, a preliminary determination is made (to which responses can also be filed), and eventually a public hearing is held, at which testimony can be given. Investigations are to be completed within one year, but this deadline can be extended by six months. There are mechanisms for provisional measures when warranted, and also to impose measures retrospectively.

If, at any point during an investigation, the authorities determine that dumping is zero or negligible, the investigation must immediately cease. Assuming the investigation reveals that dumping is occurring, that domestic industry is injured, and that the dumping has caused the injury, the authorities issue an order setting anti-dumping rates, which can be in effect for up to five years. After this period they must expire, unless an interim review indicates that ending the measures would injure domestic industry.

While foreign producers are not compelled to respond to an anti-dumping investigation, a failure to respond can allow the authorities to determine the exporter’s dumping margin on the basis of the best information available. As such, a failure to participate can ultimately result in a higher anti-dumping rate.

In petitioning for an anti-dumping investigation, it is necessary to use strategy to make the best case. Likewise, when responding to an investigation, it is important to use strategy to present the best case that one is not dumping, or to minimize the apparent margins. Whether one is a petitioner or a respondent, anti-dumping investigations are considerable work, but the results can make a big difference in profits, and even business survival.

On December 10, 2025, the National Assembly of Vietnam adopted Law on Vocational Education No. 124/2025/QH15, which took effect on January 1, 2026, replacing Law on Vocational Education No. 74/2014/QH13 of 2014. The new law broadens the categories of institutions eligible to deliver vocational training, introduces vocational upper secondary schools, and shifts governance structures for private institutions from ownership-representative boards of management to stakeholder-based school councils. These reforms aim to diversify training providers, align programs with labor market needs, and create a more flexible, open vocational education ecosystem, offering expanded opportunities for foreign and domestic investors, universities, and enterprises. Some highlights of the new Law on Vocational Education are presented below. Expansion of Vocational Training Levels and Programs In addition to elementary, intermediate, and college—the three levels of vocational training program set out under the 2014 Law on Vocational Education—the new law expands the structure by introducing two new levels: Vocational high school training programs are placed between elementary and intermediate levels, and are aimed at combining upper secondary education with vocational training, expanding options for learners after graduating from the lower secondary level. Other vocational training programs are not specified in detail under the new law, but aim to equip learners with the capability to perform and handle one or several simple tasks of an occupation. Expansion of Vocational Education Providers The new law reclassifies and extends vocational education providers by classifying them into two distinct categories: Vocational education institutions, which include colleges, intermediate schools, and vocational high schools. Establishments participating in vocational education activities, which include vocational education centers, vocational-continuing education centers, continuing education centers, other centers with vocational education functions, enterprises, cooperatives, and higher education institutions. Vocational education providers may provide one vocational training level only, or several/all levels, depending on the type of provider. The

Thailand’s Office of the Consumer Protection Board has opened a public hearing period on draft regulations governing the transfer of direct sales and direct marketing businesses. The draft Notification of the Direct Sales and Direct Marketing Committee: Criteria and Procedures for Business Transfer and Amendment of Registration for Direct Sales or Direct Marketing Businesses establishes a compliance-focused process with strict documentation requirements and timelines for transferring direct sales and direct marketing businesses. The proposed framework also defines the roles of transferors and transferees and establishes application procedures with the Office of the Consumer Protection Board. Applications may be submitted in person or electronically and will be examined to confirm they are complete, authentic, and compliant with legal requirements. This includes verification that: The transferee meets all required qualifications; No disqualifying factors apply; and The applicant is not subject to legal restrictions. The public hearing period is open until April 29, 2026. Direct sales and direct marketing business operators should prepare for these proposed requirements to ensure compliant implementation once the regulations are finalized.

Thailand’s National Broadcasting and Telecommunications Commission (NBTC) has publicly indicated that it is preparing a new regulatory framework for data center operators that may introduce foreign-ownership restrictions. In particular, the NBTC is considering reclassifying data center operations from a type 1 telecommunications business license to a type 3 license. If implemented, this change would subject data center operators to a significantly more stringent regulatory regime, especially in relation to foreign ownership and control. The NBTC has indicated that it intends to propose a draft framework to the NBTC board. This would be followed by a public hearing process, with a view to implementing the new rules within 2026. Under the Telecommunications Business Act B.E. 2544 (2001), as amended, telecommunications businesses operating under type 3 licenses are subject to foreign ownership restrictions, including a requirement that less than 50% of the total issued shares be held by foreign shareholders. In addition, type 3 licensees are subject to foreign dominance restrictions, which prohibit arrangements that allow foreigners to dominate the business. These foreign dominance restrictions are broad in scope and may capture various forms of direct and indirect control or influence. This includes circumstances in which a foreign national is able to influence or control the formulation of policy, management, or business operations, or the appointment of directors or senior executives. At this stage, the exact scope of the proposed rules remains unclear. Businesses with existing or planned data center operations in Thailand should therefore monitor upcoming NBTC developments in this regard and prepare for the expected public hearing process.

In March 2026, the Myanmar Investment Commission (MIC) introduced two regulatory updates affecting investors planning new investments or implementing MIC-approved projects. Minimum Investment Conditions for Tax Incentives MIC Notification No. 1/202 clarifies the minimum conditions for investments in promoted sectors to qualify for tax exemptions or relief under the Myanmar Investment Law. The notification establishes the following requirements: Investors must contribute at least 35% of the total investment amount in cash, as reflected in the relevant proposal or endorsement application. Where an investment involves a foreign loan, the investor must obtain approval from the Central Bank of Myanmar, together with a loan repayment schedule, and provide evidence that both the foreign loan proceeds and the capital contribution have been remitted in cash through an authorized dealer bank. Chinese Yuan Accepted for Investment Capital The MIC also issued Investment News Bulletin No. 1/2026, confirming that Chinese yuan (CNY) is now accepted as foreign investment capital for applications for MIC permits and endorsements, in addition to US dollars (USD). Investment funds contributed in CNY may be remitted through banks authorized to deal in foreign currency in CNY, following the same process currently applied to investments made in USD. These developments may affect how foreign investment capital is structured and remitted, as well as the availability of tax incentives for investments under the MIC framework.
