Remanufacturing identified surplus is the use of components of a material alone or combined with others to create a new material or product (e.g., mail transportation equipment and spare parts). Except for locks, manufacturing is not a core competency of the Postal Service, so remanufacture may be a rare solution for the disposal of surplus and idle assets. Remanufacture would be appropriate when an internal Postal Service project that has decided to make a product has been identified by the purchase/SCM team, and these surplus or idle assets can be leveraged to reduce the costs associated with the new product or service. Because the decision to remanufacture will lead to the utilization of surplus to strategically make in-house another product at the Postal Service, as outlined in Conduct Make vs. Buy Decision Analysis, it does not require supplier involvement and should not be in the RFP.
