Quality Inspection Procedures Every Garment Brand Must Know About

Why do garment brands need quality inspection procedures?

What sets successful clothing brands apart from the rest? Unique styles and creative marketing strategies are important components to success in the apparel sector — but it is high and consistent product quality that truly makes a clothing brand endure. Product quality, especially in the apparel sector, doesn’t simply happen. It is the result of continuous quality control efforts and strict quality inspection procedures. Quality inspections are carried out at the garment supplier’s facilities during and after the production process, before the garments are shipped to the brand’s stores and distribution centers. These inspections are an essential component of quality control in an apparel supply chain, helping to detect defective products and therefore shipments, before they reach your destination market thus mitigating the risk of costly product recalls and customer complaints. This article will cover quality inspection procedures that are fundamental for ensuring the quality of your garments and apparel. The list included in here is far from exhaustive, as apparel is a very broad product category, and certain types of apparel require specific tests. Nevertheless, the quality inspection procedures described here are essential for any garment brand.

What are the fundamental steps in a garment inspection?

Whether you use in-house quality control inspectors or a third-party QC service, here are five fundamental steps that a garment inspection procedure must include:

1. Measuring garment dimensions

Your consumers want clothes that fit well and are true to size, which is why measuring garment dimensions is absolutely crucial for quality control. The dimensions of your garments must be consistent and comply with their specified sizes. It’s important to remember that discrepancies in dimensions can exist even in precise manufacturing processes. Meanwhile, apparel manufacturing still involves many manual steps, which makes the margin for error much greater. To conduct this test, the quality control inspector takes measurements of the different parts of the garment being checked and compares them against your specifications. This is done for every clothing size in your order. To make sure this check is carried out properly, your garment specifications should clearly state the points of measurement (e.g., sleeve length, neck width), the standard measurements for each size, and acceptable tolerances for each point of measurement.

Specifying tolerances for garment dimensions

QC inspectors and your supplier should be well informed of the tolerances for garment dimensions, which determine an acceptable margin of error for any defects or discrepancies. Tolerances can vary for different parts of the garment, depending on their significance to the entire piece. For example, ¼ inch may be an acceptable margin of error for a shirt’s chest width measurement, but the same shirt’s sleeve being too short or too long by the same ¼ inch would be marked a fail. The tolerances for every point of measurement should be clearly specified on the QC inspectors’ checklist.

Fit test

A garment that matches its specified dimensions is likely to look as intended when worn, but a human body is a complex shape, and correct measurements don’t always guarantee the final garment’s correct fit and look. This is why a fitting test is an important part of the garment quality inspection procedure. To carry out the fitting test, a quality control inspector will place the checked garment onto a mannequin of appropriate size, and perform a visual check. The garment should sit on the mannequin properly and look as per the reference pictures provided by the brand.

2. Accessories testing

Unreliable accessories can destroy the consumer’s overall impression of your product and brand. No one wants a garment with buttons that come loose after a day, zips that break after little use, or decorations that get ruined in the first wash. This is why the quality of your garment’s accessories can become the yardstick by which your consumer judges your product’s quality. At the same time, this crucial area is often where manufacturers might choose to cut corners and costs by buying low-quality accessories. In addition, issues with buttons and buttonholes can indicate poor stitching. QC inspectors use a variety of physical tests to identify possible defects with garment accessories such as zippers, snaps, ribbons and elastic. The tests are performed on a designated number of garments in each batch. Below are some examples.

Pull test

Predominantly used to test zippers. In this test, a QC inspector uses a gauge to pull on the accessory with a predetermined amount of force for 10 seconds.

Fatigue test

This test determines whether the accessory will last as long as intended under normal use by the consumer. A typical test on snaps or buttons would be to repeatedly button and unbutton the accessory 50 times and check for any damage to the garment after testing.

Stretch test

This check is carried out to test elastic bands and straps for proper elasticity, and to check whether the elastic or stitching stands up to being pulled or stretched. Stretch tests only need to be carried out on a small selection of finished garments.

3. Garment appearance, workmanship and other checks

This category covers a number of quality inspection procedures that ensure that the tested apparel meets your specifications and functional requirements. Such garment tests may include:

4. Label verification

Correct labeling is essential for complying with the garment labeling requirements of your destination markets. The EU and United States in particular have strict regulations regarding garment labeling, and incorrect or missing labels can see your product rejected at customs, or land you with a fine. You should always check your destination market’s specific labeling requirements, but as a rule, the garment label should contain the following information:

There are specific labeling requirements for wool, leather and fur garments, as well as for footwear, where labels must specify the materials used in each part of the footwear item.

Barcode scanning test

Correct barcodes on shipping and retail packaging are essential for tracking your shipments, and for quick processing of your products at distribution centers and points of sale. However, issues with barcodes are found very frequently during QC inspections. Barcode scanning test should be performed as part of both the labeling check and the packaging check, because the barcodes on retail packaging and those attached to shipping cartons serve different purposes and contain different information. As part of the barcode scanning test, a quality control inspector uses a barcode scanner device or app to ensure that your product’s barcode is:

5. Packaging inspection

One of the final on-site inspections for garments before shipping from the factory is to ensure the packaging is suitable to protect the products in transit and in compliance with the destination market’s regulations. Lack of attention to packaging can result in your shipment being delayed, lost or turned away at customs, or the products becoming damaged.

During a packaging check, an inspector will answer such questions as:

Shipping marking check

Last but not least, the shipping marking must be carefully checked to make sure it includes all information required by the destination market. While specific regulations may vary from country to country, shipping markings will commonly need to include:
