For more than 100 years, the ISRI specifications have helped promote consistency and quality in the trade of recycled materials in the U.S. and around the world. Thanks to a grant from the U.S. Department of Commerce’s International Trade Administration this invaluable resource is accessible online to anyone at any time.

Specifications are reviewed on an ongoing basis to ensure they meet the demands of the domestic and global marketplace. Any individual, organization, or company can file a request for additions, changes, or deletions to the specifications. ISRI will continue to update the specifications as the flow of recycled materials evolves with the introduction of new products into the supply chain.
