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.

Interest in data center land acquisition has increased significantly over the past year, with a notable rise in inquiries from investors seeking to establish digital infrastructure in Thailand. Although the sector is still in its early stages, this emerging wave of development represents a significant shift in Thailand’s technology infrastructure landscape, driven primarily by multinational technology companies and operators looking to expand their regional presence. Project Development The data center sector in Thailand is attracting a diverse range of international investors, though with clear geographic patterns. Most investors are from China, Singapore, and Japan, with some additional interest from countries outside Asia, including the United States and Europe. This investor base consists primarily of multinational tech companies and operators seeking to establish new facilities rather than acquire existing assets. Data center business activities are also a sector promoted by Thailand’s Board of Investment (BOI), which offers investors both tax and nontax privileges as well as exemptions to foreign investment and land-ownership restrictions. Projects currently underway are still largely in the land acquisition and construction phase. Unlike more mature markets where many facilities are operational and generating revenue, the predominant focus in Thailand remains on securing suitable land and beginning the building process. This means that while interest is high and land assembly is accelerating, the sector as a whole has not yet reached the operational phase that will ultimately drive licensing applications and full regulatory compliance. The licensing process itself remains at an early stage, as most projects must first complete their facilities before applying for the specific licenses required from the telecommunications authority. Once the facilities are built, the next critical step will be obtaining these telecommunications licenses, which are mandatory for data center operations. Legal and Regulatory Considerations The complexity of data center development in Thailand requires

The Land Department in Thailand’s Ministry of the Interior (MOI) plays a central role in ensuring the stability and legality of real estate transactions in the country. Its core responsibilities include issuing land title deeds, registering transactions (e.g., sales, mortgages, leases), conducting surveys for subdivision or consolidation of land, and providing information and guidance on land and property development laws. These administrative functions secure investor confidence and support transparency in the Thai property market, so any delay can have a significant impact. This is especially true for investors who depend on timely registration to secure or transfer property rights. Delays can create liquidity risks, postpone project timelines, and even reduce Thailand’s attractiveness as a real estate investment destination. This article explores the nature of these challenges, the legal framework governing the timelines for administrative actions, and remedies available under Thai law. Sources of Delay Procedural delays at land offices can arise for a variety of structural and operational reasons. These include approval processes that require several levels of internal review, heavy staff workloads, and occasional communication gaps within the bureaucratic chain. Many processes still rely upon manual documentation, which can prolong administrative steps and increase the likelihood of bottlenecks. Some delays stem from ongoing investigations into the legality of land titles. For example, a land title deed may have an annotation indicating that the title deed is under investigation to verify its legality. Even though this annotation does not legally prohibit the sale or transfer of the land, in practice, most prospective purchasers are reluctant to proceed with a transaction until the annotation is removed. As a result, the land can become effectively illiquid during the investigation period, leading to significant investment delays. While such investigations are essential to maintaining the integrity of Thailand’s land registration system, prolonged inquiries

Thailand and the United States signed a memorandum of understanding (MOU) titled “Cooperation to Diversify Global Critical Minerals Supply Chains and Promote Investments” on October 26, 2025, signaling a new strategic alignment aimed at developing Thailand’s mineral sector, particularly in rare earth elements (REEs). The MOU has implications for investments in technology, manufacturing, and other related sectors. This update outlines the key provisions of the MOU and the potential opportunities and legal navigating points for businesses. Objectives The primary driver of this agreement is the US initiative to diversify global supply chains for critical minerals and reduce reliance on current market leaders, particularly China. For Thailand, it represents a major opportunity to attract high-tech investment and develop its downstream processing industries. The cooperation is set to focus on five main areas: Technical knowledge: Exchange of technical expertise and international best practices to strengthen Thailand’s mining and processing sector. Joint cooperation: Establishing workshops, seminars, and scientific collaboration to boost innovation. Regulatory practice: Promoting good governance and streamlining regulatory and licensing procedures. Information sharing: Sharing data on potential projects and global market prices. Full-value chain: The MOU covers the entire mineral lifecycle, from exploration and extraction to processing, refining, and recycling. “First Opportunity to Invest” Clause The most debated provision within the MOU states that “participants expect to have the first opportunity to invest . . . in critical minerals assets that may be sold in Thailand.” Business implications: This clause is widely interpreted as granting US companies a first look or preferential access to investment opportunities in Thailand’s critical minerals sector. This could be a significant advantage for US-based or affiliated companies in mining, technology, and energy seeking to secure a foothold in a developing REE supply chain. Thai government position: Thai officials, including the prime minister, have publicly clarified
