How is AQL used for packaging inspection?
AQL provides a statistical acceptance plan using lot size, inspection level and defect classes; it does not define the product specification or desired defect rate.

- Approval sample and decision owner
- Required date and Mainland China delivery point
- Change and repeat-order record
Quality control
Four elements of an auditable inspection plan
AQL and sampling
Agree lot definition, inspection level, AQL values and acceptance numbers by defect class; AQL is not a quality target.
Defect classification
Use product-specific critical, major and minor examples with photographs so different inspectors make consistent decisions.
Inspection plan
Define checkpoints, sample size, measurement tools, defect photos and release authority before production starts.
Approved reference
Seal, date and identify the approved sample with linked files and limits; keep reference ownership and storage controlled.
Execution method
Four actions from RFQ to production
Translate expectations into criteria
Use dimensions, tolerances, test methods and defect photographs.
Inspect at the right stages
Place controls at incoming material, first article, in-process and final release as risk requires.
Record traceable results
Identify lot, SKU, sample size, inspector, tools, findings and disposition.
Close corrective actions
Contain affected stock, verify root cause and confirm the fix before repeat release.
FAQ
Questions buyers often ask
How is AQL used for packaging inspection?
AQL provides a statistical acceptance plan using lot size, inspection level and defect classes; it does not define the product specification or desired defect rate.
What should be written in the specification?
At minimum, define AQL and sampling, Defect classification, Inspection plan, Approved reference, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
