What he says:

Our mission is to provide customers with excellent procurement services and help them win the market and build a strong reputation through high-quality products.

Black Wang has been engaged in quality management since 2004. Before founding Comsourcing, he accumulated 18 years of experience in quality management. In his last role, he worked as a Quality Manager at TUV Rheinland China for 14 years.

He is highly familiar with factory quality control and believes that product quality stems from total quality management, starting with incoming material inspection, first sample confirmation, process inspection, functional inspection, 100% finished product inspection, random inspection, and product functional reliability testing. He understands the control methods and techniques for each critical point.

For trade order quality management, he also possesses extensive experience and unique insights. He believes that the best quality control prevents potential issues at the start. Detecting problems only during production or final inspection is often too late. Therefore, he advocates quality control for trade orders beginning with the first sample.

Choosing a good factory is essential, but it does not guarantee a flawless production process. Even the best factories can make mistakes, which is why real-time order monitoring is necessary. IPI and DUPRO inspection service effectively supervises unexpected situations during production. If a quality issue arises, the factory can promptly rework and improve, minimizing losses for both the customer and the factory.

Black’s achievements in quality management have established him as a well-known expert at TUV Rheinland. While at TUV, he conducted extensive quality management training for QC teams of major clients such as LIDL Asia and Delta Sport. During negotiations with OBI, he showcased TUV’s quality control expertise, earning customer trust. The cooperation between TUV and OBI continues to this day.

Excellent quality engineers require a strong technical background. Black is also an expert in electrical appliances, power tools, and electronics. He is highly familiar with safety standards such as EN 60335, EN 62841, and EN 60950, and has developed inspection procedures, specifications, and test methods for numerous products.

 

Now, Black brings all his technical expertise and quality management experience to serve Comsourcing customers.

Business operation

What she says:

“Creating value for customers is our job.”

“Purchasing is a very detailed job. Calculate the cost of materials, compare quotations, bargain with the factory, and go to the site to negotiate for better price. This job is full of challenges, but when we get a better price for our customers, and customers benefit from it, we have immense pride.”

Once you get to know our team, you will see our strengths.

This is a comprehensive quality management system made up of several critical components. The more attention is paid to front-end quality control steps, the lower the likelihood of problems at later stages.

 

By executing every step diligently, high product quality is naturally achieved.

Manufacturer Survey

Choosing a reliable supplier is the foundation of any business cooperation, and a good supplier can help you achieve great success, while a poor one may cause significant problems.

Whether it is a long-term partner or a new potential manufacturer, we provide a background survey report to give you a comprehensive understanding of the supplier.

 

We focus on the most critical aspects, including factory qualifications, credit, quality, testing capabilities, production capacity, and delivery capabilities. Only by assessing these factors can we determine whether a manufacturer is capable of becoming your reliable supplier.

Sample evaluation

Whether you are familiar with the product or not, our quality engineer will conduct a sample inspection of your target product, issue a report, and highlight key points for quality control.

Quality plan customization

We will create a customized quality plan for each of your products. The plan includes sampling schemes for different inspection stages, AQL acceptance levels, inspection points, test points, improvement suggestions, and more.

We listen to your product quality requirements and incorporate them into the plan, ensuring comprehensive control over every quality point.

The quality plan is updated based on issues identified at different inspection stages, allowing subsequent inspections to focus on previously found defects.

 

Inspections are conducted according to the quality plan, and the inspection report provides a clear overview of your products’ quality status.

First sample inspection

The most effective quality control is to address potential issues from the start, making the inspection of the first product crucial.

 

While the first sample cannot represent the quality of the entire batch, it can reveal potential problems.

 

The issues and suggested improvements are documented in reports, and we work with suppliers to implement corrections. By identifying problems at the very beginning of production, there is sufficient time to resolve many issues.

Packing inspection

Errors in packing material content can cause significant losses, mislead customers, and even damage your brand reputation. Therefore, inspecting packaging materials is essential.

We check all information on export cartons, color boxes, rating labels, instruction manuals, logos, and markings to ensure compliance with your documents. Any deviations are identified at the start of production.

 

We also inspect packing material quality, including carton strength, color box printing, instruction manual layout, barcode readability, desiccant quality, and more.

Initial Production inspection

Although the first sample inspection is completed, it only covers a specific sample, and some issues that may arise during production cannot be detected.

The IPI inspection is essential, especially for high-value orders or high-risk products, as it identifies problems during production, enabling the manufacturer to rework and improve in time to prevent further losses.

 

This important inspection process covers packaging, product safety, functionality, appearance, internal structure, and compliance testing. The inspection report provides a clear overview of your product’s quality status.

DUPRO inspection

In the following three situations, we increase the number of process inspections, which may occur at any stage between 20% and 60% of production, with one or more inspections possible:

  1. The products are high-risk, such as electrical appliances, gasoline tools, or baby toys.
  2. The order value is relatively high, requiring additional risk control.
  3. Many issues were found in previous inspections, necessitating closer monitoring of factory improvements.

Please note that we determine the necessity, number of inspections, and inspection items based on the actual situation.

If conducted, you will receive an inspection report. 

100% FRI inspection

The 100% FRI inspection is the most important of all inspections, as it is the final check before the product is delivered to you.

Normally, it is conducted when the product is fully finished and packed. Under normal operation, it can be performed when at least 80% of the goods are packed, provided the products are 100% finished and packing will be completed soon.

Similar to the DUPRO inspection, the 100% FRI covers the entire product inspection range, with additional checks based on issues found during the DUPRO inspection and the updated quality plan.

We use the scientific AQL method to classify defects by severity and determine whether the product meets your quality requirements by counting defects in each category against the acceptable limits.

 

The focus of this inspection is to test the product according to the quality plan. Safety is prioritized—for example, high-voltage and ground resistance tests for electrical products are conducted at 100% standards. Functional durability and reliability are also tested by simulating real use conditions, such as running a lawn mower continuously or testing the writing length of a ballpoint pen. In short, our inspection goes beyond appearance and basic functionality, covering nearly all risk areas of your product.

Loading supervision

Have you ever experienced short-loading, damp goods due to damaged containers, or wasted space from improper loading? Without monitoring, many accidents can occur during the loading process.

 

We send engineers on-site to inspect container quality, supervise the entire loading process, and provide detailed photos. Our loading supervision service ensures your goods are in good condition before shipment.

This service is performed when on-site loading supervision is required.

Verification of certificates and test reports

For orders requiring test reports or certificates for electrical products, toys, and similar items, our experts review factory certificates, such as CE and GS, to ensure products meet required standards.

Typically, when you make an inquiry, we already select products and manufacturers with valid certificates, as certificates often reflect product and factory reliability.

 

If your market requires you to be the license holder, we can discuss whether to issue a secondary certificate based on the factory’s certificate. Compared with obtaining a separate certificate, a secondary certificate can save significant costs.

Coordination with laboratories for testing and certification

If a test report or certificate is required for your order, we will coordinate with the factory to prepare and submit the necessary samples.

At the same time, our experts will liaise directly with accredited third-party laboratories, addressing technical issues such as test standards and testing methods to ensure the smooth issuance of reports and certificates.

 

Thanks to our strong relationships with reputable laboratories and our deep knowledge of testing procedures and certification processes, we can help you obtain certificates more efficiently and with greater reliability.

Factory Audit coordination

In today’s market, many major brand clients require suppliers to hold quality system and social responsibility certifications. For example, LIDL requires factories to have BSCI and ISO 14001, while the U.S. market has anti-terrorism qualification requirements.

Most of our partner factories already hold strong certifications, and we will select the most suitable suppliers for you.

 

If your client requests a new audit or requires a third-party certification company to conduct one, we will coordinate the entire process on your behalf until the corresponding certificate is successfully obtained.
