Seven Bridgestone Corp. plants, including the company's facility in Des Moines, Iowa, have received platinum level certification from Caterpillar Inc.
Platinum is "the highest rating in the Caterpillar's supplier quality excellence process (SQEP).
"SQEP is a program through which Caterpillar promotes ongoing improvements in suppliers' process management," according to Bridgestone officials.
"Among the tens of thousands of suppliers that serve Caterpillar from around the globe, platinum level certification is only awarded to suppliers that are able to consistently deliver world-class products and services of impeccable quality. The recognition demonstrates Bridgestone's commitment to pursue improvement in productivity and efficiency, subject to strict quality control across the entire supply chain."
