At present The Industrial Estate Authority of Thailand (IEAT) has established 34 industrial estates located in 15 provinces nationwide:

Industrial Estates are developed and managed by the Industrial Estate Authority of Thailand (IEAT). Industrial Zones are under the Ministry of Industry (MOI) and aim to support regional development and specific industrial sectors. Industrial Parks are established entirely by the private sector. Total land must be at least 500 rai, with 60-70 percent allocated to factories. All required facilities must be provided. Most Industrial Parks are promoted by the Board of Investment.

An Industrial Estate in Thailand resembles an industrial town or industrial city providing complete infrastructure necessary for industrial operations such as ample electricity, water supply, flood protection, waste water treatment, solid waste disposal, etc. It is accessible to seaports, airports and other transportation centers. Besides providing communication facilities and security systems, an industrial estate also contains commercial banks, and a post office. Some have customs offices, schools, hospitals, shopping centers and other facilities needed for investors and workers. In fact, it is a self-contained community.

The industrial property market in Thailand consists of two main segments: the sale of serviced industrial land plots (SILP) in estates, parks, and zones; and the rental of ready-built factory (RBF) buildings including warehouses.

The latter part of 2003 saw improvement in the industrial market, particularly in the rental market for Ready Built Factories (RBFs).

RBFs are popular with small to medium-sized companies whose start-up costs are lower. They can quickly mobilise operations once they get orders from a customer
