BOI Promotion in the Eastern Economic Corridor
Application support across Rayong, Chonburi, Chachoengsao and the adjacent industrial zones — Thailand's flagship investment region for S-curve industries.
The EEC: Thailand's flagship BOI region
The Eastern Economic Corridor groups three provinces — Rayong, Chonburi and Chachoengsao — along Thailand's eastern seaboard. The region was designated under the EEC Act to host targeted high-value activities and is served by Laem Chabang port, U-Tapao airport and a dense network of industrial estates.
For BOI applicants, an EEC location adds a layer of enhanced privileges on top of the standard BOI framework — additional tax exemptions, expanded deductions and faster One-Stop Service Centre processing for visas and work permits in many promoted activities.
Belaws prepares EEC-focused applications across all promoted industries, from EV manufacturing in Rayong to logistics in Laem Chabang and smart-city projects in Chachoengsao.
Six key EEC investment clusters
Each EEC cluster aligns with a specific industrial vocation. Picking the right zone for your activity matters because it influences both BOI category eligibility and operational costs.
Map Ta Phut Industrial Estate (Rayong)
Petrochemical and heavy industry hub managed by the IEAT. Home to Thailand's largest cluster of chemical manufacturers.
WHA Eastern Seaboard Industrial Estate
Multi-tenant estate spanning Rayong and Chonburi. Strong automotive, electronics and supporting-industry presence.
Amata City Chonburi & Rayong
Two of Thailand's most established privately-managed estates. Diverse tenancy from auto to consumer goods to logistics.
Laem Chabang Port Corridor (Chonburi)
Thailand's primary deep-sea container port. Logistics, freight forwarding and export-oriented manufacturing.
EECi — Eastern Economic Corridor of Innovation
Wang Chan Valley R&D zone in Rayong dedicated to research, biotechnology and advanced industry pilots.
EECd — Digital Park (Chonburi)
Sri Racha digital cluster targeting data centres, cloud infrastructure, IoT and digital services.
Activities prioritised in the EEC
The EEC framework gives priority to targeted high-value industries. The list below maps the BOI categories most commonly approved for EEC-based applications.
Next-generation automotive
Electric vehicles, batteries, EV charging systems, autonomous and connected mobility.
Intelligent electronics
Advanced electronics manufacturing, semiconductors, IoT devices and intelligent appliances.
Robotics & automation
Industrial robotics, automated production cells and integrated factory systems.
Aviation, logistics & digital
Aviation MRO, logistics platforms, data centres, cloud services and broader digital-economy activities.
How an EEC-located BOI application unfolds
An EEC application follows the standard BOI workflow with extra location-specific verification.
- Activity checkConfirm that the planned activity sits inside a BOI promotion category, and identify whether EEC-specific incentive tiers apply.
- Site selectionPick an industrial estate or zone that matches the activity. The estate's permit envelope influences both BOI processing and downstream operating permits.
- Application & filingCompile the file (project, capital structure, financial projections, technology transfer plan) and submit through e-BOI.
- BOI pitchPresent the project to the BOI committee. EEC projects often include a technology and skills-transfer commitment that needs to be articulated clearly.
- Approval & registrationReceive the approval letter, incorporate the promoted company, open the corporate bank account and transfer registered capital.
- BOI certificate & post-approvalApply for the Foreign Business Certificate, register for VAT, set up payroll, file the first BOI annual report and start the work-permit cycle.
BOI in the EEC — what to do and what to avoid
Do
- Map your activity to a BOI category before signing any lease
- Choose an industrial estate that already hosts your target activity
- Budget realistically — total timelines run eight to twelve weeks on a complete file
- Document technology transfer and skills-development commitments
- Plan post-approval compliance: BOI annual reports, machinery import schedule, employee ratio
- Use BOI's One-Stop Service Centre for visas and work permits
Don't
- Apply under the wrong BOI category to fit a desired incentive
- Promise unrealistic investment or employment figures in the application
- Confuse EEC enhancements with automatic approval — the BOI committee still decides
- Ignore the foreign-to-Thai employee ratio attached to your activity
- Skip the FBC step after BOI approval — you need it to invoice in many sectors
- Claim land ownership privileges before the BOI certificate is issued
Why the EEC concentrates so much BOI activity
The EEC was designed specifically to attract high-value foreign direct investment. Its enabling legislation, the EEC Act, set up a one-window framework for permitting, land use and BOI alignment.
Belaws operates a Bangkok office and routinely supports EEC investors travelling between the capital and the eastern provinces. Most pitch meetings happen at the BOI head office in Chatuchak, Bangkok.

FAQ
What makes the EEC different from a standard BOI application elsewhere in Thailand?
The EEC adds enhanced privileges on top of the standard BOI framework for projects located inside the three EEC provinces and on a list of priority activities. The everyday BOI workflow is unchanged; the incentives improve.
Which sectors are most often approved in the EEC?
Next-generation automotive (especially EVs and batteries), intelligent electronics, robotics and automation, aviation, biotech, advanced agriculture, logistics and digital infrastructure. The full list is published by the BOI.
Do I have to be physically based in the EEC?
The promoted activity must take place at the registered site, which must be inside the EEC to qualify for EEC enhancements. The company's head office can sit elsewhere.
Can a foreign-owned EV company get BOI in the EEC?
Yes. EV manufacturing is one of the most actively promoted EEC sectors, with several active sub-categories covering vehicles, batteries, components and charging infrastructure.
How long does an EEC BOI application take?
Approximately eight to twelve weeks end to end on a complete file: three days for eligibility, one to two weeks for filing, one to two weeks until the pitch, three weeks to registration, plus two for the Foreign Business Certificate.
What is the minimum capital for an EEC BOI?
Most promoted activities start from a paid-up capital of THB 1,000,000, but several EEC-priority activities require more. The exact figure depends on the activity category and is confirmed during the eligibility assessment.
Does the EEC have its own visa scheme?
BOI's One-Stop Service Centre handles visa and work-permit processing for BOI-promoted companies under streamlined criteria. For long-term residence in Thailand for skilled investors, the LTR visa is a separate route.
Can Belaws attend the BOI pitch meeting with us?
Yes. The pitch happens at the BOI head office in Bangkok and Belaws lawyers prepare your team and attend the meeting. We brief you on the typical questions the committee asks for projects in your sector.
