Pre-production Sample

A pre-production sample is a sample made by the seller before mass production, using the same materials, processes, and equipment as the final bulk production, based on the buyer's final approved sample or modification requests. Its core purpose is to verify whether the product's quality, specifications, packaging, etc. meet requirements under mass production conditions, and it serves as the acceptance benchmark for subsequent bulk production. Usage scenarios include: the buyer requests a pre-production sample after approving the sample to lock down production standards; the factory submits a pre-production sample for final customer approval before cutting or production begins. Precautions: the pre-production sample must be completely consistent with the final bulk goods; any change in material, color, or size requires re-confirmation; the buyer usually signs or issues written approval on the pre-production sample, and mass production may not proceed without approval; pre-production samples are generally provided free of charge, but courier fees may be borne by the buyer. Difference from an approval sample: an approval sample is a sample from the design stage, while a pre-production sample is the final sample before mass production, with greater emphasis on production feasibility. Difference from a sales sample: a sales sample is used for exhibitions or customer development, while a pre-production sample is used for order execution.
