Step 4: QC Inspection – How to Run the Three Checks That Protect Your Order

Quality control is the only stage of an apparel order where you can still change the outcome. Everything before it produces the goods; this is the step where you find out whether the goods are what you paid for. Yet most buyers treat inspection as a line item on an invoice rather than a process to manage, and that is how a 10,000-piece order ends up with a 15% defect rate nobody noticed until the container was sealed. This guide covers how to schedule, brief, and run the three inspection stages, and what to do when one fails.

Why Step 4 is a process, not an event

That is the core of it: inspection is not a gate you pass, it is a sequence you manage. The quality theory behind AQL levels and defect classification is covered separately in our AQL and quality control guide. This article is about the operational side: when to schedule, what to brief, what to ask for in the report, and what happens when it fails.

The three stages at a glance

Scheduling: the dates that decide everything

Most inspection failures are scheduling failures. The inspection has to happen while the goods are still fixable, and that means you need to know the production dates before production starts.

Get the production schedule in writing

At purchase order confirmation, ask for a production schedule with milestone dates:

• Fabric received and cut
• Sewing 50% complete
• Sewing 100% complete
• Decoration complete
• Final inspection report issued
• Packing complete and container sealed

Without those dates you cannot book an inspector, and without an inspector booked you are relying on the factory to call you when the goods are ready, which is too late to change anything. This is the same milestone discipline described in Step 3 bulk production.

Book ahead, always

• Book the inspector when the PO is confirmed, not when you hear production is nearly done
• Third-party inspection services in Asia are typically 5-10 days out during normal periods and longer in peak season (August to October, and February to March)
• Confirm the inspector’s name and agency in advance. A different inspector on the final stage than on the in-line stage means a different eye, which is not necessarily a problem but you should know
• Require written notice from the factory at least 5 business days before each stage, and put that clause in the PO

The lead time you should actually plan

Add your own decision time on top. If you need 2 days to review a report before approving the balance payment, the final stage occupies 5-6 days of calendar time, not 2. Budget 3-7 days for the whole of Step 4 as the reference table in the 5-step process overview shows, and 5-10 days if a failure needs remediation.

Choosing an inspection service

Questions to ask an inspection agency

1. How many garments does one man-day cover? The usual figure is 150-250 pieces for a simple knit, 80-150 for a complex woven or a garment with heavy decoration
2. Do you use AQL sampling, and which standard (ISO 2859-1 / ANSI Z1.4)?
3. Do you provide photographic evidence with the report?
4. Will you inspect to my tech pack and my approved sample, or to general factory standards? The answer must be the first one
5. What is your turnaround from inspection to written report?
6. Can you re-inspect after rework, and at what cost?

Major agencies

QIMA (which absorbed Asia Inspection), SGS, Bureau Veritas, and Intertek are the recognised names. For smaller volumes, V-Trust, TestRite, and a number of established local Chinese inspection services operate at lower cost. The name matters less than two things: whether they inspect to your spec, and whether they will stand behind the report.

Writing the inspection brief

This is the document that determines whether the inspector catches what matters to you. Most buyers send a generic brief and get a generic report. A useful brief has four sections.

1. The spec reference

• Attach the tech pack, or at minimum the measurement spec sheet with tolerance per point of measure
• Identify the approved pre-production sample, with its approval date and identifier
• Identify the approved lab dip if colour matching is critical
• State the AQL level and the defect classification you are using

2. The product-specific checks

This is where a generic inspection misses things. List the checks that matter for your garment specifically. Examples from across our product guides:

3. The tolerance table

State the acceptance criteria in numbers the inspector can apply without interpretation:

• Measurement tolerance per point of measure (typically plus or minus 0.5 cm for adult knits, 1.0 cm for adult wovens, 0.3 cm for children’s)
• Colour tolerance expressed as Delta E against the approved lab dip, with the threshold you accept
• Shrinkage tolerance for washed garments
• Critical defects that are zero tolerance regardless of sample size

4. Logistics and access

• Factory address and gate contact
• Which production lines and areas the inspector may access
• Who pays the man-day fee and when (this should be you, never the factory)
• Confirmation that the factory may not brief, guide, or influence the inspector

Running each stage

Stage 1: in-line inspection (30-50% sewing)

Your objective: find a systemic problem while the factory can still fix it. At this point, a defect rate of 8% means 20% of the remaining production needs correcting. The same 8% found at final inspection means 100% of the order is suspect.

• The inspector samples from the line, not from a bundle the sewing floor has set aside
• Check the fabric first, before anything is sewn into it. A fabric problem found at 40% is cheap; the same fabric woven into 5,000 garments is not
• Measure against the tech pack, and check the tolerances you specified
• Compare colour to the approved lab dip, not to a swatch the factory kept on the floor
• Ask what the factory intends to do about any finding, and record the answer in the report

Your decision after the in-line report is one of three: continue production as is, continue with a correction (for example switch to a different fabric lot), or stop and rework the affected portion. If you approve an in-line report with an open defect without recording a remediation plan, you have accepted the defect, and the final report will simply confirm what you already knew.

Stage 2: final random inspection (100% complete, before packing)

Your objective: a pass/fail decision on the lot against your AQL threshold, before anything is packed into cartons. This is the stage that triggers your balance payment.

• The inspector takes a random sample from the whole lot, following the standard sampling procedure. A factory that hands over a pre-selected bundle is not running a random inspection
• Defects are classified as critical, major, or minor and counted
• Measurements are taken against the spec, and the results are tabulated per point of measure
• Decoration is assessed for position, colour, registration, and durability
• Trims and labels are checked against your spec, including fibre content and size

Three possible outcomes and what each one means for you:

Stage 3: pre-shipment inspection (after packing, before loading)

Your objective: confirm what is actually going in the container. This stage catches the problems that only appear once goods are in boxes.

• 100% carton count: the number of cartons and the number of units inside them. This is the check that catches a short shipment, which no amount of garment sampling will find
• Carton marks: purchase order number, style, colour, size breakdown, carton sequence, gross and net weight, dimensions, country of origin, all present and legible
• Carton integrity: no crushed or water-damaged cartons, pallets in good condition, ISPM 15 stamps present on all wood
• Random product check: open cartons from across the shipment, not just the top layer, and verify the contents match the carton marks
• Container condition and seal: dry, clean, no holes or prior cargo residue, and the seal number recorded

The carton count is the single most valuable part of this stage. It is also the one most often skipped, because it is tedious rather than technical. A 4% quantity shortfall on a 5,000-piece order is 200 pieces you paid for and will not receive, and it is entirely preventable with a count.

What to do when an inspection fails

You decide this before it happens, not in the moment. Put the remediation paths in the purchase order or the framework agreement.

The four remediation paths

The failure protocol

1. Do not release the balance payment. This is the entire point of tying payment to a passing report
2. Get the evidence in writing: the inspection report, photographs, and your own measurement data. Attach them to the claim
3. Reference your clause: the specific AQL threshold, tolerance, or remediation path in the PO
4. State your preferred path and a deadline: not a complaint, a request with a date and a consequence
5. Re-inspect the rework: an unverified rework is not a rework. Budget a re-inspection man-day
6. If it repeats, escalate: a second failed inspection on the same style is a relationship problem, not a quality problem, and it belongs in a framework agreement discussion

The realistic outcome for a first order is that the factory accepts the finding and reworks without argument, because the evidence is objective and the relationship is new and worth keeping. Save the escalation for where it is warranted.

8 mistakes that cost buyers money at Step 4

1. Booking the inspector after production is finished — by then the only remaining option is rework, and a rework at 100% completion is expensive. Book at PO confirmation.
2. Sending a generic brief — the inspector inspects what you told them to inspect. Without your product-specific checks, you get a generic report and generic defects.
3. Accepting the factory’s own inspection report — a factory that ships passes its own goods. The inspector must be independent and must be paid by you.
4. Not stating the tolerance in numbers — “acceptable quality” is not a criterion. The inspector cannot pass or fail a garment against an adjective.
5. Skipping the carton count at pre-shipment — a quantity shortfall is invisible to garment sampling and is entirely preventable.
6. Releasing the balance payment on a conditional pass without a written remediation plan — you have accepted the defects. A conditional pass needs a dated plan and a re-inspection.
7. Not keeping a copy of the approved pre-production sample — without it, the inspector has nothing authoritative to compare bulk against, and a dispute becomes an argument about memory.
8. Letting the report arrive after the container has sailed — the balance payment trigger and the shipment date are usually close together. Put the report date in the shipping plan, not after it.

Quality checks that are worth writing into every brief

Whatever your product, these belong in every inspection brief. They are cheap to check and they account for most real defects:

• Measurement: at least 10 pieces from random cartons, measured at every point of measure against the spec, with tolerance stated
• Seams: no skipped stitches, no puckering, no loose threads, correct stitch type and density at stress points
• Trims: labels present, correct size, correct fibre content, correct position, sewn not glued
• Decoration: position, colour accuracy, registration between colours, no cracking at fold lines, no bleed-through
• Colour: consistent across the batch, and matching the approved lab dip within your stated Delta E
• Construction: no holes, no stains, no fabric damage, hem and cuff finishes even and clean
• Quantity: carton count plus a unit count from opened cartons
• Packaging: poly bag type and perforation, size sticker present and correct, folding method as specified

FAQ

How long does Step 4 take in total?

3-7 days for all three stages if everything passes, which matches the reference in the 5-step process overview. In practice budget 5-10 days: you need time to review each report and decide, and the final stage sits right next to your balance payment. If a stage fails and rework is needed, add 3-15 days depending on the extent.

Do I need all three inspection stages?

For the first two or three orders with a new factory, yes. The in-line stage is the one that protects you, because it is the only one where a systemic problem is still cheap to fix. After the relationship is established, in-line plus pre-shipment is usually sufficient, with the final stage covered by the factory’s own QC plus your spot checks. For orders under 500 pieces, a single final inspection is often the practical compromise.

What if the factory refuses third-party inspection?

Walk away, or do not place the order. Any reputable factory accepts third-party inspection, it is industry standard, and it should be in your purchase order from day one. A factory that objects to independent inspection is telling you something about how it would handle a quality dispute later. Our factory vetting guide covers how to screen for this before you commit.

Can the factory suggest the inspection agency?

They can, and it is sometimes convenient, but you must not let the factory choose the inspector without your approval. A factory that pre-arranges an inspector it is comfortable with has weakened the check. Use a service the factory has no relationship with, or one that you book and pay for directly. If you use a factory-recommended agency, ask for the inspector’s name and confirm they are not a factory employee.

Who pays for the inspection?

You do, directly. Never let the factory pay, because then the factory is the client’s customer and the incentive is wrong. The cost is 150-400 USD per man-day, which is a trivial fraction of a failed order. Write it into your cost model as a line item, not as an exception. See our pricing guide for where it sits in the landed cost.

What is the difference between a final inspection and a pre-shipment inspection?

The final inspection inspects the garments before packing and gives you the pass/fail decision that triggers your balance payment. The pre-shipment inspection inspects the packed shipment and confirms quantity, packaging, and marks before the container is sealed. A shipment can pass final inspection and still have the wrong quantity in the wrong cartons, which is exactly what pre-shipment catches. They are not substitutes.

What does “rework” actually mean and is it worth accepting?

Rework means the factory corrects or reproduces the defective pieces: re-stitching a seam, re-pressing a hem, re-embroidering a logo, or re-making whole garments from the same fabric. It is worth accepting when the defect rate is low, the defects are concentrated and clearly fixable, and the fabric is sound. It is not worth accepting when defects are systemic (wrong fabric, wrong construction method, wrong sizing), because the re-made pieces will have the same problem. In that case, reject and reproduce.

How do I use the inspection report to protect myself in a dispute?

Treat the report as a contractual document. It should carry: the date, the inspector’s identity, the sampling standard and AQL level used, the sample size, the defect counts by category, the measurement results, photographic evidence, and the pass/fail conclusion. Reference it by date and inspector in any claim you raise. Our contracts guide covers the clauses that give the report contractual weight, and why you want them in the purchase order rather than negotiated after a failure.

Can I inspect the goods myself instead of hiring an agency?

For the first order it is worth doing, both for the control and because you learn the product. It works if someone on your side knows how to measure a garment and read a spec sheet. Beyond the first order, third-party inspection is more cost-effective: your time is worth more than 150-300 USD a day, and an independent report carries more weight in a dispute than your own photographs.

How we work at Kemondo

At Kemondo Apparel, inspection is built into the order rather than bolted on afterwards, and three things follow from that. First, we provide a written production schedule with milestone dates at purchase order confirmation, so an inspector can be booked before production starts rather than after it finishes. Second, our pre-shipment inspection includes the product-specific checks listed in each of our category guides, because a generic inspection misses the rib recovery on a jogger, the stitch density on a workwear shirt, and the drawstring compliance on a children’s hoodie, and those are exactly the defects that generate returns. Third, we run in-house QC at every stage and third-party inspection at 100% production, included free on orders above 5,000 pieces, so a buyer does not have to contract with an inspection agency to get a report they can put in front of their own customers. And we will say plainly which findings we think are within acceptable tolerance and which we think should stop a shipment, because an inspector who never fails anything is not inspecting.
