PACCAR annually recognizes suppliers who exceed PACCAR's 10 ppm quality standard, or the equivalent of 10 defective parts for every million components shipped to PACCAR. To qualify, suppliers must also meet demanding criteria for customer support and continuous improvement. For 2025, PACCAR recognizes 359 suppliers in 28 countries on five continents for achieving this high level of quality performance.

"PACCAR's 10 ppm suppliers achieved and sustained exceptional quality in 2025, supporting our commitment to deliver the highest quality trucks and transportation solutions to our customers. This is a remarkable accomplishment given the dynamic market conditions," said Stephan Olsen, PACCAR vice president of quality.

Laura Bloch, PACCAR senior vice president, said, "PACCAR's top suppliers continued to improve quality while working on cost management in our competitive landscape. PACCAR develops strong supplier partnerships and is proud to recognize and congratulate these suppliers for achieving 10 ppm quality."
