Thailand's industrial landscape is dominated by the Map Ta Phut Industrial Estate in Rayong Province — recognised as the world's fifth-largest petrochemical complex. Home to over 150 industrial plants including PTTGC, IRPC, Thai Oil, Indorama Ventures, and dozens of downstream chemical producers, Map Ta Phut is the engine of Thailand's petrochemical industry. Vajra Industrial Solutions supplies API 6D ball valves, ASME B16.34 gate valves, and PED-compliant butterfly valves to Thai procurement agents, EPC contractors, and plant turnaround teams.
Key End-Users: Thailand's Petrochemical & Energy Sector
PTT — Thailand's National Energy Company
PTT Public Company Limited (formerly Petroleum Authority of Thailand) is Thailand's state-owned national oil and gas company and one of the Fortune Global 500. PTT operates natural gas transmission pipelines across Thailand (over 3,000 km), LNG import terminals, and gas separation plants. PTT's Map Ta Phut LNG Terminal (capacity 11.5 MTPA and expanding) is Thailand's primary LNG import facility, requiring cryogenic-rated API 6D ball valves (A352 LCC body, extended-bonnet gate valves) for the LNG receiving and regasification systems.
PTT Global Chemical (PTTGC)
PTTGC is the largest petrochemical company in Southeast Asia and one of the top 20 globally by revenue. Operating from Map Ta Phut, PTTGC produces olefins (ethylene, propylene), aromatics (paraxylene, benzene, toluene), and a vast range of downstream polymers and specialty chemicals. PTTGC's complex requires every category of industrial valve: API 6D trunnion ball valves for ethylene pipelines, SS 316 butterfly valves for corrosive chemical service, diaphragm valves for polymer plant slurry lines, and API 526 safety relief valves for pressure vessels across the complex.
IRPC — Rayong Integrated Complex
IRPC (a PTT subsidiary) operates an integrated refinery and petrochemical complex at Rayong with refining capacity of 215,000 bpd and petrochemical production covering UHV (ultra-high viscosity) specialty chemicals, ABS resin, and propylene. The IRPC complex is a major valve buyer for turnarounds and expansion projects — requiring API 6D gate valves, globe valves, NACE MR0175-compliant ball valves for gas oil and vacuum distillate service, and API 607 fire-safe butterfly valves.
Thai Oil — Sriracha Refinery
Thai Oil (also a PTT subsidiary) operates the Sriracha Refinery in Chonburi Province — one of the largest refineries in Southeast Asia at 275,000 bpd of crude oil processing capacity. Thai Oil's Clean Fuel Project (CFP) — a major refinery upgrade adding 45,000 bpd of new capacity and adding hydrotreating and hydrocracking units — was commissioned in phases between 2022 and 2024 and required extensive valve procurement during construction, including high-pressure Class 600–1500 gate and globe valves in chrome-moly for hydrocracking service.
Map Ta Phut Industrial Estate: 150+ Plants
Beyond the major PTT group companies, Map Ta Phut hosts global chemical majors including BASF (Thai) Limited, Dow Chemical Thailand, Indorama Ventures (world's largest PET resin producer, headquartered in Bangkok), HMC Polymers, Vinythai (AGC Chemicals), Siam Polyethylene, and Siam Cement Group's chemical division. Each of these plants operates independently managed maintenance and procurement programmes that purchase valves on a regular basis for turnarounds, debottlenecking, and capital projects.
Thai Industrial Standards (TIS) & Import Regulations
TIS and International Standards for Valves
The Thai Industrial Standards Institute (TISI) is responsible for setting Thai Industrial Standards (TIS). For industrial valves in oil, gas, and petrochemical service, Thai buyers generally specify international standards — API 6D, API 609, ASME B16.34 — rather than unique TIS standards. Thai end-users and EPCs operating to international standards (ISO 9001, API Q1) accept valves certified by third-party inspection bodies such as Bureau Veritas, SGS, or TÜV SÜD, which Vajra Industrial Solutions can arrange.
Thai Import Documentation
Valve imports into Thailand are cleared through Thai Customs (กรมศุลกากร). Key documents: commercial invoice in USD or THB, packing list, bill of lading, certificate of origin (Form D under ASEAN FTA for preferential duty, or Form AI under ASEAN-India FTA), technical datasheets, and hydrostatic test certificates. The HS code for most industrial valves (ball, gate, globe, butterfly) under Thai customs is 8481.80. For valves subject to technical product standards, import permits from relevant Thai agencies may be required — Vajra provides full documentation to support customs clearance.
Shipping to Thailand from India
Port of Entry: Laem Chabang
The vast majority of industrial equipment imports for Map Ta Phut and the Eastern Economic Corridor (EEC) area enter Thailand through Laem Chabang International Terminal (LCB) in Chonburi Province — Thailand's largest seaport and one of the top 20 busiest container ports in the world. Shipping from Nhava Sheva (Mumbai JNPT) or Mundra to Laem Chabang takes approximately 8–12 days by sea. Urgent valve shipments can be airfreighted to Suvarnabhumi Airport (BKK) in Bangkok.
