Bulk Sample

Bulk Sample refers to a sample made and drawn before mass production, using the same materials, processes, and production line as the actual bulk goods, to confirm whether product quality, specifications, packaging, etc. meet customer requirements. It usually appears after order confirmation and before mass production, and is a key node in foreign trade quality control. Usage scenarios include: customer requests for pre-production sample confirmation, factory self-inspection, third-party inspection reference, etc. Notes: The bulk sample must represent the true level of the bulk goods and cannot be specially made or hand-picked; after confirmation, it should be sealed and kept as the acceptance basis for subsequent deliveries; if the customer has not confirmed the bulk sample, do not rush into production. It differs from a 'Sales Sample,' which is used for marketing and does not guarantee consistency with bulk goods; it is sometimes used interchangeably with 'Pre-Production Sample,' but bulk sample emphasizes random drawing from mass production. The difference lies in: bulk sample emphasizes 'representativeness,' pre-production sample emphasizes 'first article confirmation,' and sales sample emphasizes 'display effect.'
