BOI Promotion & Company Setup in Chonburi (EEC)
Automotive, electronics, food technology, logistics and digital BOI applications across Amata City Chonburi, Hemaraj Chonburi and the EECd digital corridor in Si Racha.
Chonburi: the EEC's largest industrial province
Chonburi is the most populous and economically diverse province of the Eastern Economic Corridor. Its industrial footprint stretches from the Pattaya-Bang Lamung tourism cluster on the coast to the manufacturing belt around Amata City and Si Racha.
Chonburi is the default location for foreign tier-1 and tier-2 auto suppliers, electronics manufacturers and consumer-goods producers. The province also hosts the EEC's digital park (EECd) in Si Racha and a growing data-centre and cloud-infrastructure cluster.
Belaws supports Chonburi-based BOI applications across the full sector range — from auto and electronics tenants on Amata City to digital and cloud projects in the EECd corridor.
Six key BOI clusters in Chonburi
Chonburi hosts more industrial estates than any other EEC province. The right address depends on your sector and your downstream supply chain.
Amata City Chonburi
Thailand's flagship private industrial estate. Auto OEMs and tier-1 suppliers, electronics, food, packaging and general manufacturing. Service-rich operating environment.
Hemaraj Chonburi Industrial Estate
Large multi-tenant private estate near the Si Racha–Pattaya axis. Diverse sector mix from auto to consumer goods and supporting industries.
EECd — Digital Park (Si Racha)
Digital and cloud cluster on the Si Racha plateau. Data centres, IoT, cybersecurity, AI and broader digital-economy BOI activities.
Bowin / Pinthong industrial belt
Cluster of mid-sized private estates around Bowin and Pinthong supporting the auto and electronics supply chain.
Laem Chabang Port Free Zone
Free Trade Zone embedded in Thailand's main container port — port-side manufacturing, export operations and bonded logistics.

Hospitality, MICE, wellness, marine and tourism-tech BOI activities in the Pattaya City and Bang Lamung district areas.

How to qualify for BOI promotion in Chonburi
A Chonburi BOI application follows the standard six-step workflow with extra attention to estate fit and the sector mix on site.
- Activity checkIdentify the right BOI category and any EEC priority tier — Chonburi covers a wider range of sectors than any other EEC province.
- Site selectionCompare Amata City, Hemaraj, EECd and the Laem Chabang Free Zone based on sector fit, available plots and permit envelope.
- Application filingCompile and file the project, financials, capital structure and any required technology transfer plan through e-BOI.
- BOI pitchPresent the project to the BOI committee in Bangkok. Digital and data-centre projects typically include detailed power and connectivity commitments.
- Approval & companyReceive the approval letter, incorporate the promoted entity, open the corporate bank account and transfer the paid-up capital.
- FBC & operationsApply for the Foreign Business Certificate, BOI visas and work permits, then start the BOI annual reporting cycle.
BOI mistakes to avoid for Chonburi projects
Do
- Confirm BOI category fit before locking in an Amata or Hemaraj plot
- Check whether your activity belongs in EECd (digital) or a general estate
- Coordinate Laem Chabang Free Zone licensing with the BOI promoted-company timeline
- Plan power and connectivity early for data-centre projects
- Use the BOI's One-Stop Service Centre for visas and work permits
- Track BOI annual reporting deadlines from year one
Don't
- Mix unrelated activities in a single BOI application
- Assume hospitality projects in Pattaya qualify under the same incentives as manufacturing
- Skip estate-specific environmental and zoning checks
- Underestimate the foreign-to-Thai employee ratio for technology activities
- Apply before defining the registered capital strategy
- Claim land ownership before the BOI certificate is in hand
Why Chonburi has the broadest BOI footprint in the EEC
Chonburi combines auto and electronics manufacturing inland, port-side logistics at Laem Chabang and a tourism-MICE cluster on the coast — no other EEC province covers as wide a sector base.
From Bangkok, Chonburi is about 80 km on Motorway 7 — the shortest drive to any EEC core province and the most common day-trip choice for BOI site visits.

FAQ
Is Amata City Chonburi a better BOI address than Hemaraj?
There is no universal answer. Amata City has the broadest sector mix and the most mature service ecosystem; Hemaraj plots are often closer to the Si Racha and Pattaya corridors. BOI eligibility doesn't depend on the estate — only on the activity and its compatibility with the site.
Can a data centre qualify for BOI in the EECd corridor?
Yes. Data centres, cloud services and adjacent digital-economy activities are actively promoted by the BOI and the EECd designation in Si Racha adds further alignment. Power, cooling and connectivity commitments are typically reviewed during the pitch meeting.
Does a Pattaya hospitality project get BOI promotion?
Some hospitality and tourism-technology activities are listed in the BOI promotion catalogue — for example MICE venues, integrated wellness facilities and digital tourism platforms. Standard hotels are generally not promoted in mature destinations like Pattaya.
How long is the full BOI process for a Chonburi project?
Roughly 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 BOI pitch and around three weeks for promoted company registration, plus two weeks for the Foreign Business Certificate.
What is the minimum capital for a BOI in Chonburi?
From THB 1,000,000 for most promoted activities. Several EEC-priority categories require higher minimums. The exact figure is confirmed during the eligibility assessment.
Can a foreign-owned electronics maker own land in Chonburi?
BOI promotion grants the right to own land for the promoted activity, which is an exception to Thailand's foreign land ownership restrictions. The right activates once the BOI certificate is issued.
Do BOI visas cover engineers at the Amata City office?
Yes. BOI's One-Stop Service Centre handles visas and work permits under a streamlined regime for BOI-promoted companies. The foreign-to-Thai employee ratio depends on the activity.
How does the Laem Chabang Free Zone interact with BOI?
A company can be BOI-promoted and operate inside the Laem Chabang Free Trade Zone. Free Zone operations follow Customs rules; BOI privileges follow BOI rules. The two regimes coexist and are commonly combined for export-oriented manufacturers.
