Ministry of Industry

The Factory Act was introduced to monitor the factory construction, factory expansion, business operations and safety measures. However, the Ministry of Industry can decide the following things:

  • The factory size
  • Reject the establishment of certain factories that are too many in Thailand. They manage the quantity of every type of factory.
  • The quality, type, and ratio of raw materials that will be used in the factory.
  • The quality of the good that will be produced in the factory.
  • The kind of energy that will be used in the factory.

Types of Factory

According to the Factory Act, there are 3 kinds of factories. They are:

Category 1

The first type of factory can manufacture or operate any time. They don’t require any permission before operating. Still, they have to follow the rules and regulations under the ministerial regulations. The factory which has one of the following is considered as category 1 factory:

  • 5 to 20 horsepower or
  • 7 to 20 workers.

Category 2

  • 20 to 50 workers
  • 20 to 50 horsepower.

Category 3

The last type of the factory needs to get an approval from the officer prior to manufacturing. A factory that produces pollution is category 3 factory. It must have:

  • 50 horsepower or 5 workers.

This type of factory must apply for a license before starting its operations in Thailand.

  • Application form

The Category 2 and Category 3 factories are required to pay the annual fee. The annual fee must be paid from the first day of the operation of the factory and every year following.


The Category 1 and 2 factories are prohibited from near public places. They must be 50 meters away from schools, temples, hospitals and government offices. On the other hand, Category 3 factories must be at least 100 meters away from the public spaces. They should be situated within an appropriate area with sufficient room for its operation. The reason is that it must not cause a nuisance to people or the property nearby.
