About Amarit

>> Company Background

THE AMARIT GROUP OF COMPANIES was founded in 1970 by Captain Amarit Visuddhidham and since that time has had a part in almost every well drilled in Thailand.The company is named after Captain Amarit Visuddhidham and his business partner, Khun Pravat Sangsuphan, who began providing services to foreign oil and gas companies when they first came to Thailand to participate in the 1st petroleum concession.We were among the first few agencies established when the oil and gas sector started in Thailand.The services provided to clients at that time were feasibility studies to support the setting up and operation of companies and the services they would require, such as customs clearance and immigration, labour contracting and serving as the oil concessionaires' representative to government offices and ministries.

To date, we have expanded our services to yard, office rental and warehouse rental, transportation (trucking/haulage), as well as heavy equipment and vehicle rentals. To support these, we maintain offices in Bangkok, Songkhla and Sattahip.
