Luxury Handbag QC Checklist Before Shipment: Seven Zones, Twenty-Four Checks

Three Ways to Run the Checklist, Compared

The same twenty-four checks can be run three ways, and the choice decides what the checklist is worth. A bench-led check is run by the line itself and is fast and free, but it is not independent. A brand-side check is independent and thorough, and costs travel. A third-party check is independent, documented, and costs a fee per inspector day.

Most programmes use two of the three. The bench runs the checklist at 20-30 per cent complete, where speed of correction matters more than independence, and a third party runs it at 100 per cent packed, where independence matters more than speed. The brand-side visit is reserved for a first drop or a new material, where there is still something to learn.

Zone One and Two: Exterior Panels and Seams

Start on the outside, because that is where a customer starts. Check panel match first: on a matched shell, tiles or grain should agree across the centre line within 3 mm, and the panel should sit within 2 mm of the drawn alignment mark. Then check the seam: pitch at 8-9 per inch, no more than one stitch of variance over 25.4 mm, and a topstitch 2.5 mm from the edge held to ±0.3 mm.

• Pitch: 8-9 per inch, variance of one stitch over 25.4 mm, read at three points per seam.
• Topstitch distance: 2.5 mm from the edge, held to plus or minus 0.3 mm.
• Seam deviation: under 0.5 mm over a 100 mm run, read with a steel rule.
• Slant: constant at 15-20 degrees, with no reversal along a run.
• Panel match: tiles or grain agreeing within 3 mm across the centre line.
• Thread ends: trimmed to 1.5 mm and set with wax, not left to lift.

The seam deviation check deserves a note on method. Lay the rule along the seam rather than across it and read the largest gap between rule and stitch line. It takes fifteen seconds, needs no equipment beyond a rule, and it is the single most reliable indicator of whether the panels were clicked and nested carefully or hurried.

Zone Three: Edge and Corner

Edge work is where most designer pieces are failed, and it is checked by feel before it is checked by instrument. Run a fingernail from panel to edge: a well built edge feels continuous, with no ridge at the coat boundary and no lip standing proud. Then measure: a micrometer should read a dry film between 0.10 and 0.15 mm after three coats.

Dry film

0.10-0.15 mm after three coats

Ridge at the coat boundary

None, by nail

Corner mitre gap

0.2 mm or less

External corner radius

8-10 mm

Film above which it fails

About 0.25 mm

Cure before packing

Stated in hours, not appearance

Edge after hardware setting

Re-checked for lifting

Sanding between coats

Light pass at 400 grit

The corner is the second place to look, because it is where the piece is set down, picked up and abraded. A mitre that gaps by more than 0.2 mm is not a cosmetic issue: the corner is where the edge coat fails first, and an open mitre will show it within weeks rather than seasons.

Zone Four: Hardware and Closure

Hardware is checked in four ways, and the fourth is the one usually left out. Seating: no gap larger than 0.2 mm between plate and panel, and no rock when the piece is set down. Plating: 0.15-0.3 µm on brass, verified per lot. Finish: 24 hours of salt spray on a standard specification and 48 on a high-wear one. Feel: the closure worked ten times and the resistance described in writing.

Feel belongs on the checklist because it is the one property of a closure that cannot be read off a gauge and the one a customer notices in the first ten seconds in a boutique. Described in writing at sampling and checked again at release, it stops a difference in setting from being read as a difference in quality.

Zones Five and Six: Interior, Base and Feet

The interior is checked for fit rather than finish. With the bag empty there should be no more than 1 mm of lining standing away from the base board, and the lining seam allowance should be a full 10 mm so it cannot pull through the fold. Pockets sit where the tech pack places them, and any branding application is checked for position, depth and alignment.

• Lining slack at the base: 1 mm or less with the bag empty.
• Lining seam allowance: a full 10 mm, not skimped at the fold.
• Handle drop: the two sides agreeing within 2 mm under a 250 g load.
• Base: five feet at 5 mm, set after edge work, standing level when empty.
• Pocket placement and branding position: as the tech pack places them.
• Interior seams: pitch consistent with the exterior, even where unseen.

Handle drop is measured under load rather than empty, because an empty measurement hides the difference. With the bag empty and 250 g applied, the two sides should agree within 2 mm; a visible difference beyond about 4 mm is what a customer reads as the piece hanging crooked.

Zone Seven: Packing, Cartons and Documents

The last zone is the one that decides whether what passed the bench arrives in the same condition. Cartons at 5-ply and 32 ECT, each piece bagged, tissue between hardware and any adjacent panel, no void left to shift in, and a carton weight held under about 15 kg. Documents are checked alongside: the inspection report, the material test reports and, where a listed shell is used, the CITES documentation.

Barcode and labelling are part of the same zone and are checked against the retailer specification rather than against the tech pack, because a piece that cannot be scanned at goods-in is a return that has nothing to do with how it was made. Transit testing to an ISTA drop and vibration sequence is run once per packaging specification.

Classifying What You Find: Critical, Major, Minor

A finding is classified before it is counted, and the classification does more work than the count. Critical means unsafe or non-compliant, with zero acceptance: a needle fragment, a restricted substance above limit, a closure that fails under load, or a missing document on a listed shell. Major means a customer would return the piece. Minor means a customer would keep it and a critical eye would notice it.

The last row is the one that prevents the most arguments. A natural hide is not a uniform substrate, and a checklist that treats every mark as a defect produces a run in which nothing passes. The agreement to make at sampling is which panel positions are visible enough to reject marks on and how large a mark has to be before it counts.

What to Photograph and What to Record

Photograph every finding before re-work begins, with the piece identifiable and a scale in frame where size matters. Record the figure rather than the verdict: an edge film of 0.14 mm tells you something next season, while a note that the edge was acceptable tells you nothing. Keep both against the order and the colourway.

1. Photograph each finding before re-work, with the piece identified and a scale in frame.
2. Record readings on the full drawn sample, not on a convenient subset.
3. Take at least five pieces on bench-level checks such as handle drop and lining slack.
4. Keep the record against the order number and colourway for the season.
5. Issue the report before re-work begins, so the two are not confused.

The fifth item sounds obvious and is routinely missed. A report issued after re-work describes what the pieces became rather than what they were, and it is the difference between evidence and a claim when a question is raised a season later.

The Release Decision and the Reserve

Release follows the count. At 50 drawn pieces the lot is accepted on 3 major defects or fewer and rejected on 4 or more, with critical defects at zero regardless of count. Where a lot is rejected, the re-work reserve, typically 2-3 per cent above the run quantity, is what allows the finding to be corrected without waiting for another cutting.

The programme runs through our validated partner factory Quanzhou Yingming Bags, an SGS-validated site with 7 production lines and about 200,000 pcs per month of capacity, holding export experience since 2014. Sampling takes 6-10 working days, or 12-15 on a complex build; bulk occupies 35-50 days; minimums sit at 500 pcs per style and colourway; and shipments leave FOB Xiamen with FOB, CIF and DDP terms available. Running the full checklist with a reserve adds roughly USD 4.80 per unit.

What Sits Outside the Checklist

Four things cannot be checked on a table. Restricted substances under REACH Annex XVII and California Prop 65 require a laboratory. Colour fastness to rubbing is tested to ISO 105-X12 and read on a grey scale, typically held at 4-5 dry and 4 wet. Tensile strength is tested to ISO 3376 and finish adhesion to ISO 11644. And traceability, evidenced through Leather Working Group tannery audits, is a document rather than a measurement.

None of these belong on a pre-shipment checklist, and all of them belong in the order. The discipline is to keep the two apart: the checklist decides whether this lot leaves, and the laboratory and the documents decide whether the material behind it was ever right in the first place.
