Thailand's Eastern Seaboard by the Numbers
Thailand's Eastern Seaboard — Chon Buri and Rayong provinces — is the manufacturing heart of ASEAN. International buyers sourcing from Thailand land here for a reason. Five numbers that tell the story:
1. ~70% of Thai manufacturing exports
The two provinces account for roughly seven-tenths of Thailand's manufactured-goods exports. Automotive plants (Toyota, Honda, Mitsubishi, Isuzu, Mazda, Nissan) cluster here, and the entire Tier 1 / Tier 2 supplier ecosystem follows the OEM plants.
2. ~$25 billion annual auto exports
Thailand is the world's 10th-largest automotive producer. Most of the export volume — completed vehicles plus parts — ships out from this manufacturing belt to ASEAN, Australia, the Middle East, and beyond.
3. 4 major industrial estate operators
Pinthong, Amata, WHA (post-Hemaraj merger), and Rojana. They differ on location-vs-port access, infrastructure model, tenant mix, and lease economics. We mapped them all in our buyer guide.
4. ~30 minutes to Laem Chabang port
The closest cluster — Pinthong / Bowin — sits within a half-hour truck ride of Laem Chabang container port. Logistics economics are unbeatable.
5. ~3,000 active manufacturers in the directory
Our directory currently surfaces ~3,000 verified Thai manufacturers, the bulk concentrated in this belt. Filter by auto parts, industrial estate, or warehouse to drill down.
