Introduction

We were established in Thailand in February 1999 as a general trading company belonging to the Mitsubishi Materials Trading Group.
Since our founding, we have developed our business through transactions based on trust with many customers and suppliers.
In 2013, we were reborn as an International Trading Company (ITC) with approval from the BOI.
By combining products and materials from group companies with our unique supply chain built from extensive experience and trusted suppliers, we propose solutions to meet diverse needs and contribute broadly to the industrial development and economic expansion of Thailand.
Guided by the Mitsubishi Materials Group's vision of “Designing the Circular Economy,”
we will continue to create new markets and new value, remaining a company loved by society.
