What are Third-Party Inspections, and What Benefits do They Offer?

by | Sep 9, 2021 | Product Inspections, Quality Control

When you import goods from overseas or outsource manufacturing to a domestic partner, you must ensure that your products meet all specifications, legal requirements, and customer expectations.

Unfortunately, it becomes more challenging to accomplish this if you do not have your own presence at the factory. And if your supplier is halfway around the world, it becomes even more difficult.

To remedy this, many importers conduct third-party inspections before, during, or after production.

What exactly is a third-party inspection?

A third-party inspection is the evaluation or assessment of your goods for quality control purposes. As the name suggests, it is neither carried out by the factory nor by you, the buyer. Instead, you hire an independent third-party inspection company (like Insight) to conduct it.

If you have a presence near the factory, you could consider conducting your own product inspections. But it is essential to evaluate the pros and cons of doing so versus hiring a third party. Here we discuss the benefits of third-party inspections to help you make the best decision possible.

Who Should Conduct Product Inspections?

Product quality inspections can be carried out by either the manufacturer, the buyer, or a third-party inspection service.

Reputable factories should have their own quality control measures in place, and although they may have professionally-trained staff, their QC staff is always accountable to factory management. As such, the QC department’s interests may not fully align with yours.

To hold your supplier accountable, you could choose to conduct periodic inspections yourself at the factory. But this requires you to have a presence near the facility and travel there regularly. If you are importing from overseas, this becomes incredibly complicated and may not be worth the cost.

This is where third-party quality control service providers come in. Since you are the one hiring them, they are not accountable to factory management. They will also have professionally-trained inspectors proficient in sampling methodologies like AQL (Acceptable Quality Limit).

What are the Benefits of Conducting a Third-Party Inspection?

Some of the benefits of conducting a third-party inspection are:

Impartial Inspectors

Since a third-party inspector is not affiliated with the factory or your company, they will give an impartial, independent report. As such, you are more likely to get an accurate picture of your goods on the ground.

Qualified Inspectors

Third-party inspection agencies have the right qualifications, training, and experience when it comes to product inspections. You will find that some agencies specialize in a particular industry which means that they understand what to look for during the inspection process. They also may work faster and more efficiently, finishing the required inspection within a set period.


Unless your order volumes are high enough to justify a permanent presence near the factory, hiring an inspection company can help lower your costs. Inspectors can travel to the supplier’s facility at any point in the production process, and you will only pay based on the “man-days” spent.

Increased Sales & Customer Satisfaction

Having your order inspected while it is still at the factory helps ensure that you receive quality goods. If you supply consistently high-quality goods, consumers are more likely to become loyal to your brand. As such, they may refer your products to friends and family and write about your brand on social media, leading to improved business outcomes.

    Hi. Thanks for this article. The question is that “When” the inspection is being done? Suppose the inspection done prior to the days of shipment, boxes are labelled, checked. But what if exporter do not load that particular cargos, of change the inside material?

    The benefit will only be there, if the inspection do the inspection on the day of the loading of the cargo, & mention the Container Number in the inspection report.

    Otherwise, who knows goods checked on monday are being exported on thursday or not!

    Please reply.

      Pre-Shipment Inspections should take place when production is 100% complete and at least 80% packed.

      We generally recommend that pre-shipment inspections take place 2-3 days prior to the ship date from the factory as this allows time to remediate any observations from the inspection that require attention or reworking.

      However, if there is a concern that the goods might not be loaded correctly or if there is a customized container loading schematic, you can conduct a Container Loading Inspection to reduce the risk of products being swapped at loading.
