MATERIAL PROCUREMENT Caterpillar responsibly sources the raw materials used to build our products. As the world’s leading manufacturer of construction and mining equipment, off-highway diesel and natural gas engines, industrial gas turbines and diesel-electric locomotives, Caterpillar responsibly sources the raw materials used to build our products. Our supply base includes approximately 27,000 suppliers around the world providing raw materials and manufactured components across broad categories and technologies for aftermarket and production parts. These purchases include a variety of unformed steel products, cut or formed to shape and machined in our facilities; steel and iron castings and forgings, machined to final specification; and finished components, made to Caterpillar or supplier-developed specifications. We also help keep those materials in circulation for as long as possible. We maintain global strategic sourcing models to meet our global facilities’ production needs while building long-term supplier relationships. We look for suppliers and business allies who demonstrate strong values and commit to the ethical principles outlined in the Caterpillar Supplier Code of Conduct. We also expect suppliers to comply with the sound business practices we embrace, follow the law and conduct activities in a manner that respects human rights.
