Soprema U.S.A, Inc’s Quality Control Department is dedicated to the absolute compliance with quality standards set by a number of agencies. Our company is ISO 9001:2008 registered and submits to audits performed by our registrar and intercompany auditors. A number of our products are approved by agencies such as Underwriters Laboratories, Factory Mutual and Miami-Dade. All of these agencies perform unannounced quality and compliance audits. Soprema's QC Department supports our production department on a daily basis and provides testing of finished products and raw materials. Soprema has a world of experience in the production of modified bitumen and the Quality Departments of each Soprema production facility throughout the world support one another with quality standards and testing methodologies. The US and North American QC Departments perform inter-laboratory exchanges of products and test reports with one another as well as a number of raw material suppliers. We are proud of the products that we manufacture in the USA and know, beyond a doubt, that we are a world-class manufacturer of modified bitumen products.
