The objective of the Moving Texas Exports series of papers is to describe the supply chains for six of Texas’ major export commodities and identify the role of transportation in the supply chain. In Texas, the raw materials for plastic resin are found in natural gas. Therefore, plastic resin manufacturers are very sensitive to the supply and price of natural gas. The increased mining of shale formations in the United States and Texas has resulted in an increase in natural gas production. This has allowed the petrochemical industry, specifically the plastic resins subsector, to increase its competitiveness in global markets. This is the third paper in the series and documents the role of transportation in the plastic resin export supply chain and key transportation issues and concerns.
