Garment defects: critical, major and minor, with examples

Garment defects are sorted into three classes. A critical defect makes a garment unsafe or illegal to sell, and one is enough to reject a lot. A major defect would make a customer return the item or a retailer refuse it. A minor defect is a visible departure from the specification that would not stop a sale on its own. The class a defect lands in depends on the product and where on the garment it sits, so the list has to be agreed before production.

How are critical, major and minor defects defined?

The sampling standard behind inspection, ISO 2859-1, has a section on classifying nonconformities and a special reservation for critical classes, but it leaves the content of each class to the buyer and supplier. Inspection bodies fill that gap with working definitions. QIMA describes critical defects as safety or compliance failures, with an AQL typically set at zero; major defects as those that significantly affect function or appearance and would likely cause a return; and minor defects as small cosmetic issues that do not affect function.

In practice, the classes set different limits. On a typical order inspected at AQL 2.5 for majors and 4.0 for minors, minors are allowed at a higher count than majors, and criticals are not allowed at all. That is why the classification matters more than the AQL itself. Moving one common fault from minor to major can turn a passing lot into a failing one without a single garment changing. The quality control page explains the AQL limits we apply; this guide is the defect list that sits behind them.

A garment defects list by category

The table is a starting point to agree with your factory, not a standard. The column on the right is the reason the class is usually chosen, so you can move a defect up or down with your eyes open.

Fabric defects: what an inspector looks for

Fabric faults are the most expensive to find late, because they are repeated on every garment cut from the same roll. The classes above assume the fabric was already inspected before cutting, so finished-garment inspection is catching what slipped through: holes, slubs, dye streaks, shading between panels, and pilling or surface damage from washing.

Shade deserves its own rule. A garment with a front and back from different ends of a batch can look fine alone and wrong beside its neighbour on a shelf. Ask for shade to be judged against the approved lab dip or sealed sample under the same light source every time, and write whether shade variation within a garment is major, as it usually should be, and whether variation between garments in one carton is acceptable.

Sewing and construction defects

For workmanship faults, the line between major and minor is usually decided by three questions: will it fail in wear, can the customer see it when the garment is on, and can it be fixed in finishing?

• Stress seams, such as crotch, underarm, shoulder and waistband joins, get the strictest treatment. An open or broken stitch here is major.
• Stitch density below the tech pack figure is major if it weakens the seam, minor if it is cosmetic.
• Uneven hems, twisted legs and off-centre plackets are major where they show when worn.
• Loose threads and small marks are minor, because a finisher can clear them.

Decoration adds its own list: print cracking or poor adhesion after wash, embroidery puckering or wrong thread colour, and misplaced artwork measured from a fixed reference point. Put the placement tolerance in the tech pack in millimetres, or it will be argued on the day.

Measurement, labelling and packing defects

A measurement outside tolerance is only a defect if the tolerance was written down. Classify by point of measure: body width, length and sleeve decide the size and should be major when out of tolerance; details like pocket position or cuff height are usually minor. Keep the tolerances and the points of measure in the same document, such as our tech pack template, so the inspector is measuring against the version you approved.

Packing defects are easy to dismiss and expensive to receive. A carton with the wrong size ratio, a barcode that scans as another size, or a missing carton mark can see a retailer refuse or re-handle a delivery at your cost. List the packing checks the same way as garment defects: polybag size and closure, folding method, hangtag position, carton dimensions and gross weight, and the shipping marks on two sides of every carton. Then class each one, usually as major where a retailer or warehouse would reject it and minor where it is purely presentational.

Labelling is a legal matter, not a cosmetic one. In the United States, the FTC’s guidance on the Textile and Wool Acts requires most clothing to carry fibre content, country of origin and the identity of the manufacturer or another responsible business. In the EU, textile labels are mandatory for products sold to consumers, with fibre composition listed in decreasing percentage order. EU national authorities can check a textile label against the product at any stage, including customs clearance, so a wrong fibre percentage or missing label is a border problem as well as a shelf problem. That is a good reason to class it as critical. The US market page and the EU market page cover each market’s label rules.

Safety: the defects that are always critical

A small number of defects are critical wherever they appear, because they can hurt someone.

• Metal contamination. A broken needle tip left in a seam can injure the wearer. A careful buyer asks the factory for its broken-needle procedure: how needles are issued and exchanged, what happens when a fragment cannot be found, and whether finished garments pass a needle detector before packing.
• Children’s drawstrings. US federal rules deem children’s upper outerwear in sizes 2T to 16 with drawstrings that do not conform to ASTM F1816-97 to be a substantial product hazard. Treat any hood or neck drawstring on children’s outerwear as critical.
• Small parts on babywear. The US small-parts rule exempts children’s clothing and accessories such as buttons from its test. That does not make a loose button on a baby’s garment safe; it means the check is yours. Pull-test snaps and buttons on garments for under-3s and class a failure as critical.

If you make children’s clothing, the kidswear page explains the extra testing it carries.

Why the same defect can be minor on one product and major on another

A 5 mm slub on the back hem of a workwear t-shirt and the same slub on the chest of a white fashion tee are different defects to a customer. The usual way to make that judgement objective is to divide the garment into zones: the front and upper areas seen first, secondary areas such as the back and sleeves, and hidden areas such as inside a hem. The same fault can then be major in the first zone, minor in the second and ignored in the third.

Record every defect the same way: the garment’s size and colour, a photograph, its zone and position, and the class given. A report built like that lets you check the inspector’s judgement instead of taking the count on trust, and it gives the factory a map of where the line is going wrong.

Price point shifts the line too. A premium product justifies moving several minors to major, or lowering the AQL, and the factory will price that risk. What you cannot do is change the classification after production. Agree it with the sealed sample in front of both sides, and record it with the purchase order.

What to do next

Take the table above, cross out what does not apply to your product, move the rows your customers would care about more, and add anything specific to your style. Put the result in your tech pack alongside tolerances and the AQL. If you want a factory in Bangladesh to work to it from the first bulk piece, send us the style and your defect list and we will agree it with the factory before production.
