Freeze the reference before inspection
Keep the approved sample or dated product photos, model and color code, measurements, packaging specification, quantities and any agreed tolerances together. An inspector cannot judge an unspecified substitution reliably.
Separate product, quantity and packaging checks
Record product condition, model/color accuracy, quantity and packaging as separate results. A scratched lens, shortage and crushed shipping carton require different evidence and resolution paths.
Photograph the method and exceptions
Show carton labels, the sample selection, representative accepted units and each exception. Do not claim a statistical sampling level or laboratory test unless it was actually agreed and performed.
Agree release and claim rules
State who can release the shipment, whether rework or replacement is allowed, the evidence required for unresolved defects and the after-sales claim window before payment.
Quick answers
What should be ready before a sunglasses inspection?
The approved model/color reference, quantities, packaging specification, inspection scope, acceptance criteria and reporting method.
Is a visual inspection a laboratory test?
No. Visual handling can identify visible condition and assembly issues, but it does not prove UV, polarization, material or regulatory performance.
What evidence should an inspection report contain?
Dated order references, carton and product photos, the checked quantity or sampling method, findings by category and clear exception records.
