An apparel inspection plan should define the product, the lot, the checks and the acceptance rules before production begins. A general instruction to inspect at AQL 2.5 leaves unanswered which defects count, how samples are selected and who decides what happens after a failure.
Build the checklist from the approved specification and risks of the actual garment. Keep laboratory testing, on-site measurements and visual inspection distinct so each result has a clear meaning.
Write the defect list before selecting the plan
Describe defects with photographs or reference samples where possible. A critical defect concerns a serious safety or applicable legal issue; major and minor categories should reflect the agreed effect on function, fit, appearance or use. Do not classify a problem as critical merely because it could require a commercial markdown.
Define how to count units with more than one issue and whether the plan uses nonconforming units or nonconformities. This distinction matters when comparing the findings with acceptance numbers. Have the inspector and supplier confirm the same counting rules.
Measurement tolerances, shade standards and packaging requirements should be attached rather than left to the inspector’s personal preference. If an issue is ambiguous, agree its classification before the inspection where possible.
Inspection-plan worksheet
Complete the plan with the inspection provider. The table is a discussion template, not a ready-made statistical sampling scheme.
| Plan element | What to record | Responsible party |
|---|---|---|
| Lot definition | Styles, quantities, colors, sizes and completion state | Buyer and supplier |
| Reference | Approved specification, sample and revisions | Buyer technical team |
| Defect rules | Classes, examples and counting basis | Buyer with inspector |
| Sampling scheme | Standard and edition, level, AQLs and switching rules | Qualified inspection provider |
| Selection | Random selection and agreed size/color/carton coverage | Inspector |
| Measurements | Points, methods, tolerances and coverage | Technical team and inspector |
| Testing | Separate methods, sample needs and limits | Laboratory or qualified provider |
| Disposition | Hold, corrective action, reinspection and release authority | Named buyer approver |
Understand what AQL does and does not establish
ISO publishes ISO 2859-1:2026 for attribute sampling schemes indexed by acceptance quality limit. Name the edition actually agreed in the contract, along with the inspection level, lot basis and relevant acceptance parameters. Ask the provider to confirm the applicable tables and rules.
An AQL is not a guarantee that the shipment contains no more than that percentage of defects. Sampling carries decision risks, and an accepted lot can contain unobserved problems. Do not translate the plan into a promised defect percentage for customers.
Do not invent sample sizes or acceptance numbers from the AQL alone. Have the qualified provider calculate and document the plan. Separate special tests or measurement coverage from the general visual sample if their sample requirements differ.
Place checks where they can prevent repetition
Incoming-material review can identify article, shade and visible fabric issues before cutting. First-off review can catch repeated construction or placement mistakes. In-line checks can reveal drift while corrective action still affects the remaining production. Final inspection evaluates the completed lot under the agreed conditions.
Record actual measurement values rather than pass marks alone. Values close to a limit across several lots can reveal drift that a simple acceptance result hides. Keep the method and reference version visible so comparisons remain meaningful.
Factory self-checks and independent inspection serve different roles. Choose the scope based on the product risk, supplier history and buyer requirements, not a blanket assumption that repeat orders need no outside review.
Define the response to a failure
A failed inspection should trigger a documented hold and review under the agreed terms. Identify whether defects are systematic, which goods are affected and what sorting or rework is proposed. Confirm cost and timing responsibilities rather than assuming an inspector’s report settles the commercial remedy.
After corrective action, use the agreed reinspection process with an appropriately selected sample. Removing only the defects found in the first sample does not demonstrate that the rest of the lot has been corrected.
Record any lawful commercial concession as specific to the identified lot and issue. A concession cannot waive applicable safety or legal requirements. Retain the report, photographs, measurements, corrective actions and release decision together so the next order can address the cause rather than merely repeat the inspection.
