A Chartered Engineer (CE) Certificate for Residual Life of Used Equipment is a technical certification issued by a qualified Chartered Engineer after inspecting and evaluating used machinery or equipment. The certificate estimates the remaining useful service life (Residual Life) of the equipment based on its physical condition, maintenance history, operating parameters, inspection findings, and engineering standards.

This certificate is commonly required by customs authorities, banks, insurance companies, public sector undertakings (PSUs), and industries when importing, purchasing, selling, or using second-hand machinery.
