We rely to an extent on outside vendors to supply us with key consumables such as graphite electrodes, alloys and other raw materials, including both scrap and scrap substitutes (e.g., prime scrap, pig iron and DRI) that are critical to the manufacture of our steel products. The raw material required to produce DRI is pelletized iron ore. Although we have vertically integrated our business by constructing our DRI facilities in Trinidad and Louisiana and also by acquiring our scrap processing and brokerage operations, DJJ, in 2008, we still must purchase most of our primary raw material, steel scrap, from numerous other sources located throughout the United States and internationally. Although we believe that the supply of scrap and scrap substitutes will remain adequate to operate our facilities, prices of these critical raw materials are volatile and are influenced by changes in scrap exports in response to changes in the scrap, scrap substitutes and iron ore demands of our global competitors, as well as volatility in currency rates and political conditions.
At any given time, we may be unable to obtain an adequate supply of these critical raw materials with price and other terms acceptable to us. The availability and prices of raw materials may also be negatively affected by new laws and regulations, allocation by suppliers, interruptions in production, accidents or natural disasters, war and other forms of armed conflict or political instability, changes in exchange rates, worldwide price fluctuations, including due to global political and economic factors, changes in governmental, business and consumer spending, inflation, increases in interest rates, labor shortages, and the availability and cost of transportation. Many countries that export steel into our markets restrict the export of scrap, protecting the supply chain of some foreign competitors. This trade practice creates an artificial competitive advantage for foreign producers that could limit our ability to compete in the U.S. market.
If our suppliers increase the prices of our critical raw materials, we may not have alternative sources of supply. In addition, to the extent that we have quoted prices to our customers and accepted customer orders for our products prior to purchasing necessary raw materials, we may be unable to raise the price of our products to cover all or part of the increased cost of the raw materials or pass along increased transportation costs. Also, if we are unable to obtain adequate, cost-effective and timely deliveries of our required raw materials, we may be unable to timely manufacture sufficient quantities of our products. This could cause us to lose sales, incur additional costs, experience margin compressions or suffer harm to our reputation and customer relationships, any of which may negatively affect our business, results of operations, financial condition and cash flows.
