What does automotive off-line parts mean?

[VanJameson]

Automotive off-line parts refer to components that come off the vehicle assembly production line. These parts may include those that failed pre-installation inspections, were damaged during production or transportation, were substandard products from supporting manufacturers, or were parts used for testing or inspection purposes (mostly exterior components). Below is the classification of automotive parts: 1. OEM parts: Components bearing the manufacturer's logo, with individual packaging and codes, primarily sourced from the original equipment manufacturer; 2. Genuine parts: Qualified parts produced by certified manufacturers. While not necessarily made by the original vehicle manufacturer, these parts carry the manufacturer's name, product brand, production address, and come with quality certificates.
