Feedstock Procurement The main feedstock for IRPC’s production process is crude oil. The company procures most of the crude oil from the Middle East through PTT and purchases some crude on the open market. In addition, the company also procure crude from domestic sources, which offer lower prices and transport costs. Crude oil from abroad is transported by large crude oil tankers to the deep sea port located in the same area as IRPC’s refineries and production complex and fed into the company’s production process, making feedstock management more efficient.
