Specify the part around function, not around a generic plastic label
A reliable plastic component brief combines geometry, mating parts, operating environment, target quantity and the dimensions that matter to assembly. That information determines whether injection molding, machining or a mixed route is appropriate.
Use the catalogue for established product families or the custom engineering path when the part is drawing-specific.
