Thailand has identified 767 factories operating unlawfully nationwide so far this year, with 53% of the violations found in the Eastern Economic Corridor (EEC), the government said on Monday 31 August 2026. Of the factories identified, 131 have been ordered to halt operations, while 636 were told to take corrective action. Legal proceedings have been launched against 391 factories, according to deputy government spokeswoman Lalida Persvivatana. The findings follow a Ministry of Industry move away from routine inspections towards a data-led system intended to spot irregularities at industrial sites. Data system flags possible violations The ministry's i-Auditor system draws on several sources of information to identify potential problems before sending cases to field inspectors. Ms Lalida said the checks include waste-management practices that do not match production data, unusual patterns in water, electricity and raw-material use, and discrepancies involving production processes or output volumes. Some information also pointed to possible trade fraud. Inspectors use i-Auditor to apply inspection standards, record their findings and prepare electronic reports, she said. No further details of the factories or alleged unlawful activities were released. The largest concentration of violations was in the EEC, the special economic development zone covering Chon Buri, Rayong and Chachoengsao, as well as surrounding provinces. More than 77,000 factories registered The Department of Industrial Works has 77,058 industrial factories registered in its system, including 5,961 in industrial estates. Among factories outside estates, 47 smaller operations are classified as Category 1, meaning they have minimal environmental or safety impact and do not need an operating licence. A further 3,361 medium-sized Category 2 plants must notify authorities before beginning operations. There are also 67,689 Category 3 factories, which are large-scale operations required to obtain an operating permit before they are established and begin operating. Ms Lalida said the government was seeking both to protect the public and ensure fair competition in industry. "Businesses that invest in wastewater treatment systems, waste management and safety standards should not be disadvantaged by operators who cut costs by failing to comply with legal requirements," she said. Public can report concerns The Ministry of Industry has also opened its Jaeng Ut, or "report the industry", platform for community reporting and tips about factory-related concerns. People are asked to provide a location, details of the issue, the date and time, and any supporting evidence that they can collect safely. Join the discussion? 1 September 2026
