As of November 7, 2025, Tuff Boy Sales, Inc. has officially been certified to the ISO 9001:2015 standard. We are delighted to serve our customers even better through the well-defined and documented processes this certification requires.

While we’ve always been committed to quality in our products and services, this certification ensures a more productive environment through faster identification and resolution of quality issues, among many other benefits. We partnered with CertFast, LLC, an accredited quality management system certification body, to achieve our certification.

Our team is proud to uphold these international standards across our manufacturing sites in Manteca and Gridley. We remain dedicated to excellence in the manufacturing of AG trailers, hoppers, and tractors.
