The short answer
Create a defect guide that distinguishes safety or function concerns from agreed cosmetic variation. Use clear descriptions, photographs and representative samples to support consistent decisions.
Words such as minor mark or acceptable bubble can be interpreted differently. The buyer and supplier should establish the inspection basis before production rather than debating appearance only after delivery.
Describe the inspection conditions
Identify the relevant surfaces, lighting, viewing distance and whether inspection is on empty or decorated bottles. Separate critical sealing and product-contact concerns from presentation-only observations.
Agree escalation and disposition
Record how uncertain findings will be reviewed, who authorizes a deviation and how affected goods will be identified. A photograph helps explain an observation but may not establish its depth, location or functional effect.
Procurement checklist
- Define defect categories with relevant specialists.
- Use controlled photographs and reference samples.
- Specify viewing and inspection conditions.
- Record limits for critical presentation areas.
- Agree the process for disputed findings.
Common question
Can an image alone establish whether a bottle defect is acceptable?
Not always. Location, dimensions and functional effect may require physical inspection or testing. Use images alongside the agreed specification and inspection method.
