Map Ta Phut Industrial Estate
Map Ta Phut Industrial Estate is the largest deep-industrial estate in Thailand by output, located in Rayong province on the Eastern Seaboard. Managed by the Industrial Estate Authority of Thailand (IEAT) under the Ministry of Industry. Anchors PTT Group's petrochemical complex, IRPC, Thai Oil's Sriracha refinery (adjacent), and a deep-water port complex. Heavy concentration of cracker, polymer, aromatics, and specialty-chemical capacity makes it the structural reference for Thai petrochemical-export performance. Operates under EEC regulatory privileges and the Eastern Special Economic Zone framework.

Estate profile
Petrochemical hub
PTT, PTTGC, IRPC complex anchor
Map Ta Phut is the operating base for PTT's naphtha cracker complex, PTTGC olefins and aromatics, IRPC integrated refinery and petrochemical, Thai Oil's (adjacent) Sriracha refinery, and numerous downstream polymer, resin, and specialty-chemical plants. Combined petrochemical output represents the majority of Thailand's polymer production capacity.
Deep-water port
Map Ta Phut industrial port complex
Map Ta Phut's deep-water port complex handles LNG imports (PTT LNG), naphtha and feedstock imports, and polymer and chemical exports. The port is operated by a mix of PTT Group subsidiaries and private terminal operators. LNG import capacity has expanded as PTT diversifies energy sources beyond pipeline gas.
EEC privileges
Eastern Special Economic Zone incentives
Map Ta Phut operates within the Eastern Economic Corridor (EEC) framework, providing BOI investment incentives, import-duty exemptions for capital equipment, and streamlined environmental-permit processes for qualifying industrial users. EEC designation accelerated investment commitments from chemical and materials companies.
Expansion
Map Ta Phut Phase 3 (MTP3) development
Map Ta Phut Phase 3 reclamation project will add ~1,000 rai of new industrial land for petrochemical downstream, battery materials, and specialty-chemical users. IEAT and private developers are coordinating Phase 3 land sales and infrastructure development targeting EEC-priority industries including EV supply chain.

Key drivers 2025-2026
Petrochemical
Polymer export cycle and crackers utilisation
Map Ta Phut's revenue and economic output tracks global polymer and aromatics pricing. 2023-2024 petrochemical margin compression from oversupply (Chinese capacity additions) reduced utilisation rates and profitability at PTTGC and IRPC. Normalisation of Asian polymer spreads is the primary 2025-2026 recovery catalyst.
Battery materials
EV battery-material downstream investment
Map Ta Phut Phase 3 targets EV battery-material manufacturers (cathode materials, electrolytes, separators) as part of BOI's EV supply-chain strategy. Japanese, Korean, and Chinese battery-material companies are evaluating Phase 3 as a Thailand manufacturing base, aligned with EEC automotive-EV focus.
LNG infrastructure
PTT LNG import terminal expansion
Thailand's shift from Myanmar-pipeline gas to LNG spot market purchases increases PTT LNG's import-terminal throughput at Map Ta Phut. LNG terminal capacity expansion and regasification infrastructure investment are ongoing capital programs with long-term impact on Map Ta Phut's energy-infrastructure role.
