Preventive Maintenance

Preventive Maintenance refers to scheduled inspections, servicing, and replacement of wear parts performed after the delivery of foreign trade equipment, machinery, or production lines to reduce failure rates and extend service life. This term commonly appears in equipment export contracts, after-sales service agreements, and technical annexes, especially for cross-border transactions involving large machinery, production lines, or high-value equipment. Usage scenarios include: the seller promises to provide preventive maintenance during the warranty period, or the buyer requires preventive maintenance to be included in a long-term service agreement. Notes: maintenance frequency, scope, cost-bearing party (usually paid by the buyer or included in the contract price), response time, and spare parts supply responsibility must be clearly specified. Unlike Corrective Maintenance, which is repair after a failure occurs, and Predictive Maintenance, which is triggered by condition monitoring data, Preventive Maintenance emphasizes planning and periodicity and is an important clause in foreign trade contracts for reducing after-sales disputes and ensuring stable equipment operation.
