This competitive solicitation seeks a contractor to produce two types of braille mailing containers (standard and large sizes) for the National Library Service, with approximately 80% standard-size and 20% large-size units. The contractor must provide preproduction control samples for approval before full production, and all units must conform to approved samples and contract specifications. The award will be based on best value tradeoff, evaluating product samples, technical approach, quality assurance plan, past performance, and price. Performance of services is not explicitly stated, but the containers are for mailing to patrons via the U.S. Postal Service. No budget amount or non-bid timelines are specified in the description.
