Why Thailand
An established industrial economy, not a frontier market
Thailand is ASEAN's second-largest economy and one of the region's most developed manufacturing bases, with decades of established automotive, electronics, machinery, food processing and petrochemical supply chains.
For an incoming manufacturer this matters more than any single incentive: components, tooling, maintenance, certification and skilled labour already exist locally. Production can start without importing an entire supply chain.
- Deep, existing supplier base across automotive, electronics and machinery
- Central ASEAN position with road, rail, sea and air links to regional markets
- Experienced industrial workforce with established technical training pipelines
- Stable industrial utilities and a mature contracting and engineering sector
- Free trade agreement coverage across ASEAN and major partner economies
Why the EEC
Thailand's designated corridor for advanced industry
The Eastern Economic Corridor covers Chonburi, Rayong and Chachoengsao and is the government's priority zone for advanced manufacturing, logistics and technology investment.
It concentrates the infrastructure a factory actually depends on — deep-sea port, international airport, motorway and rail — inside a single planning area, with additional investment incentives for targeted industries.
U-Tapao International Airport
The corridor's aviation and air-cargo hub, with Suvarnabhumi within road distance.
Motorway & rail
Direct motorway links to Bangkok and the port, plus rail freight connections.
Targeted incentives
Enhanced promotion for priority industries investing inside the corridor.
Why Chonburi
Inside the industrial belt, close to the port
Chonburi sits between Bangkok and the deep-sea port, which is why so much of Thailand's export manufacturing is concentrated there. Suppliers, contractors, freight forwarders and skilled labour are all within short travel distance.
It also offers the practical conditions a foreign management team needs — international schools, hospitals, hotels and residential options along the eastern seaboard.
Why Huichuang Industrial Zone
Land plus the ecosystem that makes it usable
A plot of land alone does not start production. Huichuang Industrial Zone pairs industrial land and infrastructure with the services an investor needs around it — construction, legal and BOI, workforce, utilities, facility management and logistics.
Because those services are coordinated by D Marg rather than contracted separately, the investor deals with one plan, one schedule and one accountable team.
- Plots for single factories through to multi-building programmes
- Ready-built and build-to-suit factory options
- Shared industrial utilities and facility services
- On-site workforce, security, canteen and welfare support
- Direct corridor access to port, airport and motorway
