Why is sample approval so important before bulk production?

Because it turns a preview item into a production control standard and prevents the factory from making unapproved assumptions during scale-up.

What should be included in a supplier sample approval record?

The approved sample version, BOM reference, protected parts, approved photos, label files, packaging version, open conditions, and approval date should all be included.

Should packaging be approved at sample stage?

Yes. Carton dimensions, inner protection, labels, and shipping marks should be reviewed before bulk production starts, not only before shipment.

What is sample-to-bulk drift?

It is when bulk production differs from the sample in materials, finish, components, labels, accessories, or packaging because the approval standard was vague or incomplete.

Who should receive the approved sample standard after signoff?

The supplier sales contact, purchasing side, production team, and final inspector should all receive the same approved standard.
