General industrial zone and free zone
Estates have general industrial zones and free zones, which affect raw-material import duties and domestic sales. Choose by market and supply chain.
IEAT estate setup: check the zone (general or free zone), land ownership rights for foreign operators, and construction and operating permits through IEAT, separately from BOI rights.
Estates under the Industrial Estate Authority of Thailand run their own permitting, and operators may receive some rights from IEAT without BOI. This page compares routes before choosing land and does not assure approval.

| Topic | Starting information | Review question |

| Land | Purchase or lease, size and zone | Land rights via IEAT or BOI |
| Production | Factory type and emissions | IEAT permits and environmental reports |
| Other rights | Free zone, foreign experts | IEAT versus BOI privileges |

Operators, including foreigners, may be permitted to own estate land for their business under IEAT law. Permission must be obtained and the land used as approved.
Estate operators obtain land-use, operating and building permissions through IEAT procedures. Check which licences are still needed from other agencies.
Some factories need environmental reports and must meet estate wastewater and air standards. Confirm power, water and treatment capacity before committing.
IEAT and BOI rights differ in scope; some projects use both. Identify where each desired tax right comes from and whether conditions overlap.
Many estates are co-run with private developers. Review purchase or lease terms, developer common charges and transfer restrictions before signing.
General preparation guidance. Check current announcements and project facts before filing; eligibility and approval are not assured.
