JST Group

What JST Group does

JST Group is a Thailand-headquartered integrated workforce and industrial services provider founded in Bangkok in 1983, listed on the HKEX main board since 21 October 2025. The company operates two interlocking divisions: HR Solutions (oil & gas manpower supply, recruitment, employer of record / payroll outsourcing across Thailand and Vietnam) and Industrial Services (corrosion control and cathodic protection, protective coatings, survey and inspection, post-weld heat treatment, marine supply). Revenue is generated primarily through professional services contracts (contract staffing, EOR per-employee-per-month subscriptions, project-based engineering) and secondary hardware sales (marine navigation, satellite communications, ATON equipment) via authorized partnerships with Dunlop Oil & Marine, SPX, Sealite, Sabik, Viasat, Inmarsat, and others.

Underlying technical capability includes full-lifecycle cathodic protection (ICCP/SACP) engineering using equipment from Cosasco, GPT, Dairyland, Borin, Metalnastri, BAC, and Deepwater; survey and inspection integration of drones, LiDAR, ROV, and AI-based data acquisition; and in-house protective coating manufacturing via subsidiary Guardian Protective Coating. A pre-qualified database of 5,000+ certified personnel (TBOSIET, BOSIET, IWCF, STCW, H2S) and 50+ AMPP-certified corrosion professionals — the highest in Thailand — supports the workforce deployment business. The company holds ISO 9001:2015 (recertified 2022 and 2024), ISO 45001, and TRACE anti-bribery certification, and operates a 44+ country footprint anchored in Southeast Asia with regional hubs in Bangkok, Sattahip, Songkhla, Ho Chi Minh City, and Cape Town.

The go-to-market is direct enterprise sales to oil & gas operators (PTT, PTTEP, Chevron, Shell, Total, Sinopec, Mubadala, Hess, ConocoPhillips), petrochemical and refining majors (Thai Oil, IRPC, SCG, Global Chemical), power generators (EGAT, RATCH, EGCO, GPSC, Eskom), and EPC contractors (Petrofac, Samsung Engineering, Worley, Technip, Saipem, CTCI). Pricing is quote-based across services; EOR is sold per-employee-per-month and recruitment operates on retained and contingency models with a 90-day replacement guarantee. Channel mix is direct enterprise field sales supplemented by SPE workshops, technical seminars, and LinkedIn-led content marketing.
