When importing products manufactured in China, it is important you integrate quality control processes in the factory you choose to work with. Most factories, including the best ones, are unlikely to produce perfect batches, so an effective quality control process will ensure that they meet product specifications and quality expectations.

So, before you sign any long-term agreement with a manufacturer, you have to hire a reliable China inspection company. This guide offers a list of the best China product inspection services providers to make your selection easy. We considered the pricing, capability, and customer focus when choosing them. So, this guide will help you choose the best.

What is Quality Inspection?

Quality inspection focuses on the product manufacturing process and product specifications for all types of goods and it is important for any importer sourcing from China.

The goal of quality product inspection is to detect problems, non-conformities, and defects in products that do not follow the specifications of the supplier, buyer, or general international standards. The problems can be solved if caught early to fix the first batch and prevent future problems. China quality inspection companies will help you do that.

Why Do We Need to Inspect for Quality in China?

A quality inspection helps you ensure that the quality of products you receive is not different from what your supplier had promised. That is important in ensuring that all your products fulfill the set legal requirements, match your specifications, and are fit for use. You would not want your products to cause harm to your target customers. Harm can manifest in various ways, including physical injury because of faulty products.

If you are planning to start an Amazon FBA business, you should expect many challenges. After all, you will be entering uncharted territory and you will deal with unfamiliar manufacturers who are already thousands of miles away. That means verifying the quality of products before shipping can be hard. Low-quality products come with many problems and they can lead to many returns, bad reviews, and reduced sales, which could affect your Amazon standing and even lead to the suspension of your account. And of course, you will not make any money in the end.

Amazon has an Order Defect Rate (ODR) policy which they determine by considering the rate of A-to-z claims, negative feedback, and service chargeback. They add the three rates and divide them by the number of orders you receive in any given period. They recommend a 1 percent ODR and they will suspend your account if the ODR exceeds 1 percent slightly. A rate that is higher than 1 percent can lead to the termination of your account. Furthermore, if any defective items get to your Amazon FBA warehouse, you will have to pull out your whole inventory to pick out all the defects.

Then, you will have to ship the products back to Amazon after the inspection is complete and dispose of the defective items if you cannot store them somewhere else or donate them. That will lead to delays in your current orders or even force you to make your product listings inactive. Lastly, your manufacturers will do a good job after you hire a third-party inspector because no one will slack off when they know that something is monitoring their performance. Besides, the inspector will hold them accountable for any defects and prevent them from cutting corners.

What are the stages of quality inspection?

The quality inspection identifies ways to reduce manufacturing costs, mitigate the causes of defective products, and reduce scrap losses. There are several stages of quality inspection, which include pre-production inspection, during production inspection, initial production inspection, pre-shipment inspection, and container loading inspection. The purpose of every inspection stage is to ensure quality and efficacy. Here is what each quality inspection stage entails.

Pre-Production Inspection
Pre-production inspection takes place before the production process starts. Some inspection companies will also do it after the assembly of the production facility. The inspectors check the raw materials and components, the golden sample or prototype, and the mass production processes. As the buyer, you would want to ensure that the manufacturer will produce goods according to your requirements.

Unfortunately, traveling to China and visiting a factory is expensive and takes time. So, hiring an inspector is the best thing to do.

During Production Inspection
During production quality inspection, known as DUPRO, entails inspecting and examining products in large quantities to detect possible faults. The inspection takes place after 50-70 percent of the products are complete and checks for discrepancies. After that, the inspectors submit a full inspection record to their clients in the form of photos or reports. This type of inspection is important for:

Shipments with various types of goods in large quantity
Branded products that require an undisturbed production process
Important shipments with departure time restrictions.
Reexamination when the pre-production inspection results are unacceptable.
Initial Production Inspection
Initial production inspection involves checking the quality of raw materials used in the production process. The purpose of this inspection is to ascertain that the manufacturer can offer the needed quality. Here is what the inspection entails.

Checking the factory capacity in regards to the components and production so that they can estimate the product ready date.
Checking the factory’s quality control unit to ensure that it meets the client’s expectations and quality standards.
Scrutiny of the production processes to ensure that the quality control measures meet the client’s requirements and expectations.
Verification of the quality and quantity of the raw materials the manufacturer plans to use.
Pre Shipment Inspection
Pre-shipment inspection takes place before the manufacturer ships goods to the buyer. So, this type of inspection is as important as DUPRO inspection. The purpose of this inspection is to:

Check the quality and quantity of products.
Identify the last-minute product irregularities and defects.
Ensure that the products meet safety standards and requirements applicable to your target market.
Container Loading Inspection
The purpose of container loading inspection is to ensure that the products are loaded onto the containers safely. Sometimes, the loading staff may just throw the products into the container, therefore, damaging them. To avoid that, quality inspectors monitor the entire loading process. Here are the things container loading inspectors do.

Record the arrival time of the container and the container properties, such as the color, plate number, type, and any other important details.
Examine the container to ensure that it meets the safety and security requirements for the safety of your goods.
Approve the condition and quality of the entire shipment by checking the products randomly.
Monitor the shipment loading to make sure that or breakages or damages occur during the loading.
Note down the container’s seal number.

How Much Does an Inspection Cost in China?

The cost of the quality inspection in China is not uniform. However, most professional quality control agencies base their price calculation on a man-day basis. In China, the fee for every man-day inspection is USD 100-300. A man-day refers to one inspector working for one day. Still, several factors affect the cost of the inspection in the country. Here are the factors.

Professional Level of the Inspector
The professional level of an inspector is among the factors that affect the cost of the quality inspection in China.

The Distance to the Factory or Inspection Site
China is a very large country and most quality inspection companies have offices in major cities such as Shanghai, Beijing, Shenzhen, and Guangzhou. So, if the inspection has to take place in a small town, the inspectors will have to travel from their city of residence to the factory.

As a result, they will spend money and time. At the end of the day, the companies will include the transportation costs in the invoice they send to you. Some quality inspection service providers will be cheaper than the others are because they have inspectors in many places and they do not have to cover long distances.

The Checklist
The quality checklists consist of what the inspectors have to check. Inspection companies in China use different checklists. Actually, some companies will only do the basic checks while others will do more comprehensive ones. Furthermore, some companies will go-ahead to prepare an inspection checklist for every client. They may provide a video of the inspection site too. So, the checklist dictates the amount of work an inspector has to do and affects the price.

Every quality inspector has to pass through extensive training. When choosing an inspection company in China, you have to ensure that their members of staff have the following abilities.

Ability to Speak English
Quality inspectors must have excellent English language skills in writing and reading. That is for the reason that importers have to provide inspection materials, such as artwork, item specifications, inspection criteria, inspection standards, and QC checklists, in English. You will possibly do the same. Even more, an inspector who is proficient in English will find the documentation of findings easy.

Attention to Detail
A quality control inspector must be detail-oriented and observant. Minor product defects are hard to detect but they might ruin your good relationship with your customers and lead to losses. So, you need someone who can easily detect them. Attention to detail also allows the inspectors to identify the cause of the defects.

Effective Communication Skills
A quality control inspector should have good communication skills. Inspectors are left to work alone in a factory for hours or even days. So, if something goes wrong or a question arises, they have to communicate with the factory manager or staff. An inspector that is reluctant to voice concerns or questions will end up making judgment calls or relying on their instincts, which is bad. Good inspectors are objective and they should direct problems to the factory or their supervisors.

Honesty is important in quality inspection. The quality inspection industry is prone to corruption problems than the other industries in Southeast Asia. Some suppliers substitute inferior materials for the ones specified for production. They may even lie about the safety and certification of their products. Even more, they may pressurize the quality inspectors indirectly or directly to provide an inaccurate report. Inspectors who visit the same factory many times are likely to know the factory staff at a personal level. So, when possible, hire different inspectors for every inspection.

Technical Ability
A quality inspector should have a technical background in your product class. Still, most inspectors can inspect if your products are not complicated or unique. When hiring third-party inspection services in China, ensure that they can work with MS Office, digital cameras and are familiar with measuring devices.
