Amendments to Thailand’s Factory Act

The Factory Act (No. 2) B.E. 2562 (2019) and Factory Act (No. 3) B.E. 2562 (2019) were published in Thailand’s Government Gazette  on April 30, 2019. These will amend the Factory Act B.E. 2535 (1992). The Factory Act (No. 2) will become effective 180 days after publication—that is, on October 27, 2019—while The Factory Act (No. 3) became effective on May 1, 2019. 

The main changes introduced by Act (No. 3) are administrative, laying down the definitions, appointment procedures, and duties and responsibilities of the local government authorities tasked with enforcing the law related to factories. 

The key amendments of Act (No. 2), which has a more practical impact on business operators, are laid out below.

Definitions

Under the new legislation, the definition of “factory” is updated to mean a building, place, or vehicle using machinery of 50 horsepower or more, or having a minimum of 50 workers (increased from 5 horsepower or 7 workers under the previous legislation), with or without machinery, in its operations. In addition, “construction of buildings” will no longer fall within the definition of “factory set-up.”

Increased Exemptions

The following types of factories will now be partially exempted from complying with the Factory Act: 

  1. A factory belonging to a governmental authority;
  2. A factory for study and research;
  3. A factory for training at an education institute;
  4. A family-owned factory; and
  5. A factory necessary for or related to a non-factory business and located in the same space.

License Renewal

Prior to the amendment, a factory license was valid for a period of five years from the start of operations, subject to certain exceptions. However, under Act (No. 2) a factory license will not expire until the factory ceases doing business.

Private Inspector

Act (No. 2) authorizes machinery and factory inspection duties to be carried out by private inspectors who are qualified and licensed in accordance with requirements laid down in Act (No. 2).

These amendments mean that business operators will be able to set up factories with greater ease. The amendments will also apply to all currently valid factory licenses as well as applications now under consideration.

On September 29, 2025, Thailand’s Office of the Personal Data Protection Committee (PDPC Office) published its Regulations on the Review and Certification of Binding Corporate Rules B.E. 2568 (2025) (the Regulations). The Regulations provide clarity on the PDPC Office’s approach to reviewing and certifying binding corporate rules (BCRs) under Section 29 of the Personal Data Protection Act B.E. 2562 (2019) (PDPA), and aim to facilitate international data transfers within a group of undertakings or enterprises (a “corporate group”). In conjunction with this development, the PDPC Office also approved BCRs for two companies operating in Thailand on September 30, 2025. This milestone represents the first concrete progress since the PDPC’s Notification on Criteria for the Protection of Personal Data Sent or Transferred to a Foreign Country pursuant to Section 29 of the PDPA B.E. 2566 (2023) came into effect in March 2024. Some key features of the Regulations are set out below. Categorization of BCRs BCRs are classified into two types: (1) BCRs for Controllers (BCR-C) and (2) BCRs for Processors (BCR-P). The category must be clearly specified when submitting the BCRs to the PDPC Office. Documentation Requirement The applicant must prepare and submit the application (a standard template may be provided by the PDPC Office in the future) along with supporting documents for review and certification in the Thai language. If the supporting documents are in a foreign language, a certified Thai translation should be provided. The translation must be notarized by a notary public or qualified person. Supporting documents may include, among others, a binding instrument such as an intra-group agreement, or a list of entities subject to the BCRs. Expedited Process Requirement Organizations with existing BCR approvals under the EU or UK GDPR, or from countries announced by the PDPC under Section 28, may apply through an

Recent events at a Thai listed company, where a proposal to remove the director was not successful, amid claims that a competitor was attempting to gain control of the company, illustrate how disputes over corporate control can unfold differently at the board level and shareholder level. At the board level, removing directors of a listed company mid-term to gain corporate control is not an easy task under Thai law, as it requires a higher threshold than appointing a new director, which typically only requires a simple majority vote in a listed company. At the shareholder level, Thailand’s tender offer and competition regimes add complexity where different shareholder groups act in concert to remove opposing board representatives or otherwise influence control. In this article, we will explore why the attempted removal of a director may fail, and how the tender offer regime may apply. Key Issues at a Glance Shareholder groups may seek to convene meetings to propose changes to board composition or company authority. Such proposals can be delayed or complicated by regulatory requirements and the need for additional disclosures. Regulatory authorities and minority shareholders may raise concerns when major shareholders coordinate to influence board control, especially if such actions could trigger tender offer or merger control obligations. Companies often respond by seeking further information on shareholder relationships and potential conflicts before proceeding. Why the Director Removal Failed Under Section 76 of the Public Limited Companies Act B.E. 2535 (as amended), the early removal of a director requires two conditions to be satisfied at the same meeting of shareholders: Headcount test: At least 75% of shareholders attending and entitled to vote must vote in favor. If multiple shareholders appoint the same person as proxy, each proxy is counted as a separate head for the purpose of the headcount test,

On October 22, 2025, the Thai government posted a directive not to grant gambling licenses for gambling involving poker nationwide to crack down on illegal gambling activities. The directive was issued by Thailand’s Ministry of Interior to align with government policies to prevent the legalization of all types of gambling businesses, including poker as a sporting activity. This will result in the revocation of poker activities as sport and institute a strict ban on such activities nationwide. Businesses should note the new government’s strict approach toward gambling activities as the legal situation regarding gambling in the country continues to draw close attention.

In September 2025, Thailand’s Securities and Exchange Commission (SEC) accused a company listed on the Stock Exchange of Thailand (SET), including its current and former directors, of concealing material information in connection with its filing registration and draft prospectus. This recent enforcement action demonstrates the serious consequences of making false statements or appearing to conceal material information in IPO filings and ongoing disclosures. In addition to being subject to criminal penalties, such actions can impact the eligibility of directors and executives to serve and may cause lasting reputational damage. Key Legal Risks The Securities and Exchange Act B.E. 2535 (1992) (as amended) imposes strict liability for making false statements or concealing material information in IPO registration statements and draft prospectuses. In such cases, investors can claim for damages, and there are also criminal penalties, including imprisonment for up to five years and substantial fines, may apply to the company, its directors, and responsible officers. However, misstatements or omissions in IPO filings do not, by themselves, disqualify directors or executives from holding office, whether arising from an SEC accusation or even a final court judgment. In contrast, for ongoing disclosures after listing, such as financial statements, annual reports, and meeting notices, false or misleading statements or concealment of material information can result in not only criminal liability but also immediate disqualification of directors and executives. If the SEC accuses a listed company or its directors or executives of such misstatements or omissions, those directors or executives are immediately disqualified from their positions, even before a final court judgment. Director and Executive Qualifications Directors and executives must meet the SEC’s specified standards of trustworthiness, as set out in the relevant rules. The SEC clearly defines characteristics that are considered to demonstrate a lack of trustworthiness. For ongoing disclosures, being involved in
