About The Organization

On June 9, 1915, at a meeting of the Trustees of the West Coast Lumber Manufacturers Association, it was agreed to establish a branch of the association to serve those members who manufactured shingles. Our influence grew, and as we survived both the Great Depression and World War II, manufacturers continued their quality commitment. In 1963 the organization merged with the Handsplit Shake Bureau to become the Red Cedar Shingle & Handsplit Shake Bureau.

Manufacturers’ product lines continued to broaden and, in 1988, the members changed the organization’s name to the CSSB. In the late 1980s, mill quality control inspections were subcontracted to independent, third party quality control agencies.

Each year the CSSB’s staff answer thousands of technical questions and product selection queries. Offering informed Certi-Wood® advice and the responsibility for educating the public and building code officials falls on the CSSB. Owing to knowledgeable staff, the CSSB has earned the distinction as the recognized industry authority.

Our proud history, quality reputation and dedicated CSSB members, Directors, District Managers and staff form the Certi-Wood® team that showcases trusted Certi-label® products to the world.
