Knowing what types of quality control inspection types you need will help you pick the best one. Before your product can reach amazon or any other place you sell, you need to carry out a quality inspection. Quality inspection is the process of examining characteristics of a product to establish whether they conform to specified requirements and meet your approval. You can carry out the quality inspection in 3 stages of the production process giving you three quality inspection processes.

The types of quality inspection are

1. Pre Production/ Factory Audit,

2. During-Production Inspection, and

3. Final Random Inspection/ Reshipment Inspection.

It is vital to have an early assessment to enable the supplier to make the necessary corrections before shipment. One of the main reasons these three types of inspection exist; the end game is to ensure that you, the importer, receive the correct products in the right quantity and quality.

3 Different Types of Quality Inspection

1. Pre-Production Inspection

Pre-production inspection is known as ‘Initial Production Inspection’ or ‘Factory Audit.’ Pre-production inspection is the type of review under which many factors get checked before production can begin. Some of these factors include assessing raw material used in the production process, factory documents, staff competency, and machinery conditions.

Pre-production inspection is essential because the quality of final products depends mainly on the accuracy of the raw material’s quality, the staff’s competence, and the type of machinery used during the production process. A fault in one of these key players is likely to result in faulty final products. For example, having defective raw materials is expected to result in defective final products.

For this reason, pre-production inspection occurs to ensure that all the raw materials conform to the specified requirements of the materials needed in production and, more importantly, to assess the factory’s competence to produce your goods.

2. During Production Inspection

More often than not, pre-production inspection will not suffice as conclusive for the entire production process. During the production process, other errors may occur that may affect the product’s initial quality. It is for this reason that During Production Inspection is essential.

During Production Inspection, or ‘In-Line Inspection,’ enables you to ensure uniformity in all products before production is complete. An in-line inspection allows the factory to take immediate corrective action against defective products or the production process itself.

Quick detection of in-line production errors

For instance, spelling errors on a product’s labels, once detected during in-line inspection, can be corrected by checking the machine in charge of labeling. The review saves you time and reduces losses incurred at the end of the labeling process if the inspection is done at the end of the production process.

Allows you to ensure production is on schedule

Furthermore, in-line inspection enables you to estimate how long it will take before the products can be ready for shipment.

Gives you confidence

Your quality control inspectors’ in-line inspection enables you to be confident of where production is taking place. The check prevents the manufacturer from subcontracting without your approval or knowledge. Once your inspection company conducts an in-line inspection, you will have confidence and trust that you are dealing with the manufacturer you had initially contracted.

Remember, in-line inspection requires highly specialized inspectors as it is tough to detect defects in the unfinished product. Having technical inspectors is for your benefit.

3. Pre-shipment Inspection

‘Pre-shipment Inspection is the most common type of inspection in the production and shipment industry. It occurs at the end of production, right before shipment can be made.

It is important because you, as the importer, need to be sure that all products are within the required specifications before the shipping company can take on the products.

Other benefits of conducting pre-shipment inspection include:

Allows you to decide on whether or not to substitute products

Carrying out a pre-shipment assessment gives you time to decide whether to replace defective products for other products that meet your criteria.

Ability to take immediate corrective action

It also allows the manufacturer to correct errors that might affect the production, such as packaging and measurements. Let’s say, as an example, you specified that the products are in groups of 10, but some of the packages are in groups of 12; the manufacturer can easily take corrective action against this error.


From the types of inspection outlined, which kind of quality inspection will you choose? Weigh your budget, finalize what you want and give your criteria to your inspection company, and they will do the rest. Good luck!
