INSPECTION CONTROL / 01
Inspect the approved order, then preserve the decision trail.
A pre-shipment inspection is useful only when the inspector receives the same controlled product definition the buyer approved. The report must identify the inspected lot and the limits of the work, while the buyer’s record connects findings, corrective action, reinspection and release authority.
Freeze the supplier, site and approved order baseline
Give the inspector the exact legal seller, actual inspection site, purchase-order number and revision, SKU list, quantities, approved drawings, bill of materials, packaging artwork and named golden or approval sample. State which document controls if two references conflict.
Record any approved factory, material, component or specification change before booking. An inspector cannot reliably test an order reconstructed from sales messages or an unnamed sample.
Establish the named sample and approval decision before inspection →
Build the controlled purchase-order baseline first →
Preserve any earlier in-process findings and continuation decisions →
Define the lot and prove it is ready to inspect
State the lot identity, ordered quantity, completed quantity, packed quantity, storage locations and units excluded from the lot. Set a readiness threshold and require dated evidence before the inspector travels, so unfinished or selectively presented goods do not silently change the sample frame.
On arrival, the report should record what was available, where it was located and how the sample was selected. If the declared lot and visible lot differ, pause and obtain buyer instructions rather than changing the inspection basis without a record.
A result for one defined lot cannot be carried forward to another production run, replenishment, reworked lot or future shipment without a new decision.
Check the inspection body’s competence, impartiality and exact scope
ISO/IEC 17020:2026 sets requirements for the competence, impartiality and consistent operation of bodies performing inspection. Ask who will perform the work, which methods and equipment will be used, how conflicts are managed and whether the required product, process and location fall inside the offered scope.
Global ACI has assumed the former roles of IAF and ILAC since 1 January 2026. Where accredited inspection is required, identify the relevant accreditation body through the Global ACI recognised accreditation bodies directory, then use that body’s own directory to inspect the inspection body’s current accredited scope. Accreditation supports competence for a stated activity; it does not prove that every report, sample or commercial conclusion is correct.
Define the sampling plan, defect classes and decision rule before arrival
Name the lot size, inspection level or other sampling inputs, sample size, selection method, critical/major/minor defect definitions and acceptance or rejection numbers. Tie each defect class to the product specification, user risk and contract instead of accepting an inspector’s generic labels after findings are known.
ISO 2859-1:2026 provides lot-by-lot acceptance-sampling schemes indexed by acceptance quality limit (AQL). Use the applicable licensed standard and qualified input to set the plan. AQL sampling supports a decision about a defined lot under that plan; it is not a 100% inspection or a promise that every unit conforms.
Turn product requirements into observable checks
List the identity, quantity, materials, dimensions, tolerances, workmanship, colour, assembly, function and safety-related checks that can be performed at the site. Name the method, tool, sample quantity, expected result, permitted tolerance and evidence required for each check.
Separate visual or functional inspection from laboratory testing and regulatory assessment. If a material, component or claim requires a certificate or test report, match that document to the legal holder, site, product, model and tested sample rather than asking the inspector to infer compliance.
Match certificates and test reports to the ordered product →
Inspect packaging, markings, quantities and required documents
Check unit, inner and master-carton packaging against approved artwork and pack-out instructions. Record barcodes, model and batch markings, warnings, origin markings, carton dimensions, weights, assortment, sealing and visible transit protection where those items are in scope.
List the commercial invoice, packing list, inspection record, test evidence, declarations, labels and other shipment documents the buyer expects. The inspector can record whether named items were presented and matched to the brief; the destination-market regulator or qualified adviser remains the authority for the buyer’s product, import and compliance obligations.
Make every nonconformity traceable through correction or reinspection
Require each finding to show the requirement, observed condition, defect class, affected SKU, sample count and clear photo or measurement evidence. Keep disputed or untestable items visible; do not erase a finding because the supplier promises to fix it later.
For rejected or held work, record containment, proposed correction, affected quantity, root-cause or prevention action where material, responsible owner and due date. Define whether documentary review, targeted recheck or a new representative inspection is required. Supplier photos alone should not silently close an inspection hold point.
Separate the inspector’s report from the buyer’s release authority
Compare the final report with the inspection brief, approved order revision and open-exception register. Record who reviewed it, which exceptions remain, what corrective evidence was accepted and whether the permitted action is hold, correct, reinspect, release shipment or release a named payment milestone.
Do not release the final payment or shipment only because a report says “PASS”. Confirm the beneficiary and any changed payment instruction separately before money moves. Use the bank-account verification workflow →
Shipment release is not the same decision as contractual delivery or risk transfer. The ICC Incoterms® 2020 rules allocate specified costs, risks and obligations under the sale; an inspection result does not rewrite the agreed rule, named place or wider contract.
The WTO’s pre-shipment inspection material addresses inspection activities contracted or mandated by governments, including checks of quality, quantity and price. A buyer-arranged commercial inspection is a separate contract-control process: define its authority, scope and release effect in the buyer–seller and inspection arrangements rather than importing government-program rules into a private order.
Keep the release inside the wider supplier decision record →
INSPECTION BRIEF / 02
Minimum fields to lock before the inspection is booked
| Control area | Lock before booking | Report should preserve | Hold when |
|---|---|---|---|
| Order baseline | Seller, factory, PO/specification revision, SKUs and approved sample | Exact references used and any conflict or missing document | The inspected goods cannot be tied to the approved revision |
| Lot readiness | Lot identity, quantity, completion threshold, locations and exclusions | Available quantity, location and sample-selection trail | The visible lot differs from the declared sample frame |
| Inspector scope | Body, personnel, methods, equipment, impartiality and accredited scope if required | Who attended, when, where and which methods were performed | Required competence, access or equipment is unavailable |
| Sampling | Plan, lot size, sample size, selection method and defect thresholds | Units selected, defects by class and decision calculation | The plan changes after results are visible without buyer approval |
| Product checks | Observable requirements, method, tolerance and evidence format | Measured or observed results against each requirement | A release-critical requirement was skipped or could not be tested |
| Pack and documents | Artwork, pack-out, labels, markings and named deliverables | Results, photos and documents presented at inspection time | A required marking, pack rule or document remains unresolved |
| Corrections | Nonconformity, containment, correction and reinspection rules | Open findings, supplier response and verification evidence | A promise or selective photo replaces the agreed close-out method |
| Release authority | Named buyer reviewer, permitted states and payment/shipment boundaries | Dated decision, exceptions, authorised action and evidence version | The report is being treated as automatic release authority |
RELEASE RECORD / 03
Close the inspection with an explicit buyer-owned state
| State | Minimum record | Permitted next action |
|---|---|---|
| Not ready | Lot or inspection prerequisites are incomplete or materially different | Do not inspect on a changed basis; reschedule or obtain written buyer direction |
| Inspected — review open | Report received, scope checked and findings entered in the exception register | Buyer reviews evidence; no automatic payment or shipment release |
| Hold for correction | Release-critical findings, affected quantity and correction owner recorded | Contain and correct the affected goods |
| Reinspection required | Close-out method, sample basis and corrected-lot identity approved | Perform the named reinspection before release review resumes |
| Released with record | Authorised reviewer, date, report version, closed exceptions and exact action captured | Release only the named lot, shipment or payment milestone |

How this checklist was prepared
Currawong Web’s China-side verification desk reviewed the official sources below on 31 July 2026. ISO 2859-1 supports the lot-by-lot AQL sampling boundary; ISO/IEC 17020 supports inspection-body competence, impartiality and consistency; Global ACI supports identifying recognised accreditation bodies after assuming the former IAF and ILAC roles; ICC supports separating inspection release from the agreed allocation of delivery obligations and risk; WTO material clarifies the separate government-mandated pre-shipment-inspection context.
The eight-check workflow, inspection-brief table and buyer release states are our evidence-control synthesis. We did not inspect any reader’s supplier, factory, product, lot, sampling plan, report, contract or shipment. This is general evidence-organising guidance, not an inspection service, inspection instruction for a specific product, product-compliance assessment, contract interpretation, quality guarantee or shipment approval.

COMMON QUESTIONS / 06
Keep the result inside the inspected scope
- Does an inspection “PASS” mean every unit is conforming?
- No. A report records the work performed and findings under a stated scope and sample plan. Review the lot, sampling basis, skipped checks and open exceptions before making a release decision.
- Is AQL the same as an acceptable percentage of defective goods?
- Do not use it as a simple promised defect percentage. Use the applicable acceptance-sampling standard and qualified input to define a plan and decision rule for a stated lot.
- Does an accredited inspection body prove my product is compliant?
- No. Accreditation relates to a stated inspection scope and competence framework. Product and destination-market compliance still require the applicable evidence and responsible decision-maker.
- Can supplier photos close a failed inspection?
- Only if the buyer’s pre-agreed close-out rule allows that evidence for the specific finding. Release-critical or representative-lot issues may require a targeted or full reinspection.
- Who should release the final payment?
- The buyer’s authorised reviewer should match the report, corrections, beneficiary and payment milestone, then record the exact authorised action. The inspector’s report is an input, not the payment authority.
