OEM bag factory audit inspection walkthrough on a leather goods production floor

How to Audit an OEM Bag Factory: A Buyer's Checklist

A useful audit takes half a day on the floor and years of habit to read correctly — here is what to look at, in order.

A meaningful factory audit has three parts: a document review before you arrive, a structured floor walk that follows the product from goods-in to packing, and a written follow-up with scored findings and agreed corrective actions. The objective is not to pass or fail but to establish whether the facility's actual practice genuinely matches the process it describes, and whether that process can hold up at your required volume. Audits that focus on certificates and skip the floor consistently miss the defects that reach customers.

Before You Arrive: The Document Review

Roughly a third of the audit can be completed before travel. Request a document pack in advance and review it for internal consistency — mismatches between the licence, the certificates and the stated capacity are informative in themselves. A facility that cannot produce a coherent pack on request will usually struggle to produce coherent production records later.

DocumentWhat to checkWhy it matters
Business licenceExact legal entity name, registered address, scope of businessConfirms you are contracting with the entity that will build the goods

Treat the pack as a first filter rather than a conclusion. Its purpose is to let you spend the floor time on observation instead of administration, and to give you specific questions to ask when you arrive. Where a document is missing, note it as a finding rather than waiting for it to be supplied verbally on the day.

The Floor Walk: Follow the Product, Not the Host

The single most important discipline on the day is to follow the physical flow of goods rather than the suggested route. Start at goods-in, move through storage, cutting, preparation, assembly, finishing, inspection and packing, and ask at each station what happens to the unit next. Deviations in that sequence are where defects originate.

StationWhat to observeSignals of a controlled process
Goods-in and material storeSeparation of batches, labelling, environmental controlLot codes visible; hides stored flat or rolled correctly; adhesives within shelf life
CuttingDie condition, panel sorting, shade grouping, yield controlPanels grouped by hide; damaged sections marked out; consumption tracked
Skiving and splittingThickness consistency at folds and joinsGauge checks recorded; consistent feathered edges at stress points
PreparationAdhesive application, reinforcement, creasingMeasured application; open time respected; clean working surfaces
AssemblySeam allowance, stitch density, sequenceJigs and templates in use; SPI visible and consistent; operators briefed
Edge finishingCoat count, drying, inter-coat sandingDefined coat system; drying time observed; flexibility tested on offcuts
Hardware settingAlignment, fixing security, protective backingPlacement jigs; washers or backing used; pull-test samples retained
Inspection and packingSampling, defect records, carton countsDefect log current; photographs retained; carton reconciliation performed
  • Ask to see the work in progress, not only finished goods on display in the showroom.
  • Request the defect log for the current month and check whether entries have closure dates.
  • Pick a unit at random from WIP and measure it against the tech pack you supplied.
  • Check that adhesives and edge paints are within their stated shelf life and stored correctly.
  • Observe a station changeover to see how the line handles a new style or colourway.

Questions worth asking at each station

  • "What happens to this unit next?" — an operator who cannot describe the next step may not understand the sequence.
  • "How do you know this is correct?" — the answer should reference a gauge, a jig, a template or a tolerance, not habit.
  • "What do you do if this is wrong?" — the answer should name a quarantine action and a person to tell.
  • "When were you last briefed on this style?" — checks whether operator training keeps pace with changeovers.
  • "Can you show me the record for this batch?" — records that are current to the shift indicate a live system.

Capability and Capacity: Separate the Two Questions

Capability asks whether a facility can build your construction to standard. Capacity asks whether it can build your volume in your window. A partner may be strong on one and weak on the other, and conflating them is a common sourcing error that surfaces as a schedule failure rather than a quality one.

DimensionCapability indicatorsCapacity indicators
EquipmentSkiving machines, edge finishing kit, pressing and forming capabilityMachine count and hours available per line
SkillsOperators trained on the specific construction; low turnover in skilled stationsTotal headcount and shift structure
Track recordComparable constructions in current productionMonthly output history and forward booking
MaterialsAccess to the tannery or mill you specifyVendor allocation and procurement lead time
SystemsInline inspection and corrective action recordsLine scheduling discipline and changeover efficiency
ScalabilityDocumented process that transfers between operatorsSpare line capacity in your required window

Ask directly what proportion of the line is already committed for the window when your programme would run. A vague answer usually means the booking sheet is fuller than the partner would like to admit, and a firm answer with dates is itself a good signal.

Quality Systems and the Records That Matter

Every facility can describe a quality process. The evidence is in the records, and specifically in whether those records are current, complete and acted upon. A defect log with entries but no closure dates is a filing exercise; one with root causes and verification dates is a working system.

Inline inspection sheetsCurrent to the day, per station, with named checker and corrective notes
Defect logEntries with classification, root cause, action, owner, closure date
Test recordsHardware pull, zip cycle, colour fastness, abrasion — dated and traceable
Calibration recordsMeasuring equipment within calibration date
Approved samplesSealed reference units per colourway, retained and dated
Non-conformance handlingDocumented quarantine and disposition of rejected material
Training recordsOperator training and briefing records per construction
  1. Ask for the inline inspection sheet from the current shift rather than a sample template.
  2. Trace one defect entry from identification through root cause to verified closure.
  3. Check that measuring and test equipment is within its calibration date.
  4. Confirm rejected material is physically segregated and recorded as disposed of.
  5. Verify that the retained approved sample matches the current production build.

Social Compliance and Working Conditions

Social compliance frameworks assess how a facility treats its people. The evidence is partly documentary and partly observational — how the floor looks, how long the shift has run, whether protective equipment is in use, whether exits are clear. Documentary review alone will not reveal much; the floor will.

AreaDocumentary evidenceObservational evidence
Working hoursTime and attendance records, production recordsWhether the line is running beyond the stated shift
Wages and benefitsPayroll, payment records, social insuranceConsistency between stated and observed staffing levels
Health and safetyInspection records, permits, training logsMachine guarding, extraction, PPE in use, clear exits
Chemical handlingInventory, safety data sheets, storage permitsSegregation, labelling, ventilation where adhesives are used
WelfareFacility records, dormitory arrangements where providedCondition of welfare areas and drinking water
Grievance channelsDocumented procedure and recordsWhether workers know a channel exists

Where a facility holds a current audit under a recognised framework, review the corrective actions rather than the grade. An audit with three open findings and a plan is more informative than a clean report with no detail.

Traceability, Security and Continuity

Two questions close most audits. If a customer complains in six months, can this facility trace the unit back to a material batch and a line? And if something disrupts the site, what happens to your programme? Both deserve specific answers rather than general assurances.

  • Lot codes applied at goods-in and carried through to the carton, not reconstructed later.
  • Batch records retained for the period your market requires, with a defined retrieval process.
  • Branded components and branded rejects accounted for, with documented destruction rather than disposal.
  • Design files distributed only to named personnel, with subcontractors bound by equivalent obligations.
  • A continuity plan covering material sourcing, alternative line allocation and record access.

Scoring the Audit and Closing It Out

An audit that ends with impressions has limited value. Convert observations into scored findings with owners and dates, then verify closure on the next run. Programmes that audit annually but never close findings tend to see the same issues recur, because nothing in the loop changes.

Finding classDefinitionRequired response
CriticalSafety, legality or a systemic control failureImmediate containment, root cause within days, verified corrective action before next shipment
MajorA control is absent or not followedCorrective action plan with owner and date; verification at next run
MinorAn isolated lapse or documentation gapCorrected in the normal review cycle; tracked in the log
ObservationNot a non-conformance but worth improvingRecorded and reviewed; no formal closure required

Where we host audits, the programme team prepares the document pack in advance so the visit can concentrate on the floor, and we would rather a buyer find a weakness during the walk than discover it in a return. Our production partners in Quanzhou, Fujian, build to your specification on an SGS-verified floor of 4,950 m² with 7 lines, 149 machines and 137 staff, and the records follow the same standard as the goods.

Red Flags and How to Read Them

Some findings are unambiguous. Others require judgement, because what looks like a lapse may be a reasonable practice in a different context, and a facility that is strong in one construction may simply be unfamiliar with yours. The table below separates findings that should stop a programme from findings that should be recorded, discussed and reviewed.

ObservationSeverityInterpretation
No batch coding on material in storageCriticalTraceability cannot function; a field complaint cannot be investigated
Adhesives or edge paints past shelf life in useCriticalBond and finish failures will appear after delivery, not before
Measuring equipment out of calibrationMajorInspection results are not reliable, including passed results
Branded rejects in general wasteCriticalGrey-market exposure and a breach of most manufacturing agreements
Excess WIP between stationsMajorProcess imbalance; units wait, get handled repeatedly, and suffer damage
Inline sheets are blank templatesMajorThe documented process is not the operating process
Certificate entity name differs from the contractCriticalThe certificate covers a different legal entity; verify before paying
High station turnover on skilled operationsMajorConsistency risk; correlate with the defect trend for those stations

One interpretation note. Excess work in progress is occasionally a deliberate buffer rather than a fault, and a short line with a long changeover may legitimately carry more inventory. The test is whether the buffer is controlled and tracked, or simply accumulating because the next station cannot keep pace.

Where findings are ambiguous, ask the supervisor to explain the reason for the practice. A controlled process has an explanation; an uncontrolled one usually has an excuse. That distinction, more than any checklist item, tells you what the floor will look like when your order is running.

Frequently Asked Questions

What should a factory audit checklist include?

Three parts: a pre-visit document review covering licence, certificates, capacity data and compliance declarations; a structured floor walk following the product from goods-in to packing; and a written close-out with scored findings, owners and dates. The checklist should test whether actual practice matches the documented process rather than merely confirming that documents exist.

How long does a bag factory audit take?

Allow half a day on site for a single-style programme, and a full day where multiple lines, complex constructions or a social compliance review are involved. The document review beforehand often takes as long as the visit itself. Remote audits by live video are workable for a follow-up review but less reliable for a first assessment.

Can I audit a factory remotely?

Yes, and it is increasingly common for interim reviews. A live video walk with a prepared shot list verifies many process controls, particularly record-keeping and material handling. For a first assessment, however, an in-person visit remains the stronger option, since much of what matters is observed rather than shown.

What are the red flags on a factory floor?

Excess work in progress between stations, unlabelled or unsegregated material batches, adhesives or edge paints past shelf life, measuring equipment out of calibration, and an inline inspection log that is a blank template rather than a filled sheet. Branded rejects sitting loosely in a general waste area is another.

Should I announce the audit in advance?

For a first assessment, yes. An announced visit lets the partner prepare records and gives you a meaningful conversation. Unannounced audits have a place in ongoing monitoring, particularly on social compliance, but a first visit works better as a joint review than as an inspection.

How do I verify the entity I am contracting with?

Check the business licence and confirm the exact registered legal name and address. Compare it against the name on the certificates, the bank details for the deposit, and the contract. Mismatches between these are common and are worth resolving before any payment is made.

What is the difference between a social audit and a quality audit?

A social audit assesses labour practice: working hours, wages, health and safety, and the absence of child or forced labour. A quality audit assesses process control: specifications, inspection records, corrective action and traceability. Both are relevant to a bag programme and neither substitutes for the other.

How often should I re-audit a production partner?

Most frameworks require re-audit on a defined cycle, commonly one to two years for social compliance. Beyond the formal cycle, a short annual review of defect trends, test report currency and traceability records is worthwhile, and a full re-audit is advisable after any significant change in ownership or capability.

What records prove traceability in bag production?

Lot codes applied at goods-in and carried through production to the carton, batch records linking hides and hardware to a production run, inspection sheets with dates and checkers, and a defined retrieval process. Test this by tracing one finished unit backwards rather than accepting that the system exists.

Can I bring my own auditor?

Yes, and it is common for brands above a certain volume. Agree the scope and timing in advance, and confirm what the auditor needs access to. A good partner will accommodate this readily; reluctance to allow an independent floor walk is itself a significant finding.

What should happen after the audit?

A written report with scored findings, each carrying a root cause, an owner and a date. Critical items need containment before the next shipment. Closure is verified on the following run, not assumed. The log should show the full loop from identification to confirmed effectiveness.

Does facility size indicate capability?

Not reliably. Floor area, line count and machine inventory indicate capacity, not capability. A large facility may lack experience with your construction, while a smaller specialist line may build it better. Assess capability against comparable work currently in production, and capacity against forward bookings.

What should I ask about material sourcing?

Which tannery or mill supplies each component, whether the specified grade is stocked or made to order, what the procurement lead time is, and whether declarations and test reports are available per batch. Confirm in writing before quoting, since material availability often drives the schedule more than build time.

How do I assess whether a partner can scale with me?

Ask for the volume pricing curve at 500, 1,000 and 3,000 pieces, the current forward booking position, and how a repeat order compresses in practice. A partner who can scale will answer specifically. Also confirm what happens to tooling and patterns if the programme pauses.

Should I audit before or after sampling?

Before, if the programme is substantial. Sampling is faster and cheaper once the partner relationship is established, and an audit that identifies a control gap early prevents rework later. For small pilots, a document review and reference check may be proportionate, with a full audit before the first volume run.

What is the most overlooked part of a factory audit?

The material store. Buyers concentrate on assembly and finishing, but many defects originate upstream: hides stored badly, adhesives past shelf life, batches unlabelled, or hardware mixed between clients. Walking goods-in and storage carefully often predicts quality performance better than watching the assembly line.

How should audit findings be shared?

Share it in writing, with each finding classified and carrying an owner and a date. Circulate the full report rather than a summary, including photographs. Agreement on classification matters, since the class determines the urgency of the response. Keep the log on both sides so closure can be verified independently.

What is the difference between a corrective action and a containment action?

Containment stops the immediate problem — segregating suspect stock, re-sorting a lot, or quarantining a material batch. Corrective action removes the cause so it does not recur: changing the method, the tooling, the material or the specification. Reworking a defective lot without changing the process is containment, and the defect will return.

Should I share my audit report with the partner?

Yes. An audit is only useful if the findings are discussed and agreed, and classification in particular needs joint acceptance because it sets the urgency of the response. Share the full report with photographs, agree owners and dates, then verify closure on the next run rather than assuming it happened.

How do I audit a partner I have worked with for years?

Change the emphasis rather than repeating the same checklist. Focus on trend data: defect rates by station over time, test report currency, corrective action closure rates, and whether the specification on file still matches what is being built. Long relationships drift, and drift is invisible without a documented baseline.
