How to Choose China Quality Control Inspection Services
When importing products from China, ensuring the quality of the products is crucial. This is where quality control (QC) inspection services come into play. Here are some considerations to keep in mind when choosing QC inspection services in China.
What if on-site inspection is not possible?
In the wake of the COVID-19 pandemic, on-site inspections have become challenging. However, there are alternatives to on-site inspections that can be used to check product quality. One option is to send a small sample for review. Another option is to conduct a live video call to guide factory staff through several steps, ensuring that key requirements have been met.
Is this the first time the supplier has produced this product?
If the supplier is producing the product for the first time, there are inherent risks involved. In such cases, third-party inspection services should be dispatched as early as possible to check the quality of the product. The philosophy behind this approach is to “help factories do it well” rather than “find defects and reject batches”. For soft products like apparel, it is common practice to hold a “pre-production meeting” on the day the product begins to be sewn to provide immediate feedback. Finished products are usually inspected a few days after production, which accounts for approximately 10-30% of the total quantity completed. For hard-line products, there is no standard approach, but a first article inspection (FAI) is recommended, followed by a confirmation check 4-7 days later to ensure that everything is going well.
What if the factory has produced the product before?
If the factory has a history of producing the product with acceptable quality standards, a close follow-up may not be necessary. However, if the amounts involved are quite large, or if certain products do not meet the buyer’s requirements, a close follow-up is necessary to avoid high liabilities. If the product is an off-the-shelf consumable product, a final check may only be necessary if the first order is low in quantity.
Can’t you tolerate many flaws?
If the buyer cannot tolerate a 2% or 3% defect in a shipment, it is crucial to plan accordingly. It may be challenging to find a manufacturer willing to cut and sew an order of 500 pieces and keep the defect ratio within 1%. In such cases, an independent team should be hired to 100% inspect the product and find defects. This may be cheaper outside the factory and can save the buyer money.
In conclusion, choosing the right QC inspection services in China is essential to ensure the quality of the products being imported. By considering the factors outlined above, importers can make informed decisions and mitigate risks associated with product quality.
What’s the Difference Between Factory Audits vs Product Inspection Services
What is Examined During China Factory & Supplier Audits?
China factory audits are focused on examining the big picture and are generally conducted before establishing a relationship with a new factory. They help you make good long-term decisions and decide which suppliers to work with to get the best results over time.
The three most common types of factory audits in China are Initial Factory Evaluation, Technical Quality Audit, and Social Compliance Audit. These audits focus on specific areas such as working conditions, ethical production, and adherence to laws and regulations.
When Do you Need Factory & Supplier Audits?
It is essential to perform a factory audit before working with a new factory. Follow-up audits should also be conducted occasionally to ensure compliance and track improvements. Regular audits help improve efficiency and productivity with suppliers while minimizing risk in the supply chain. They also ensure compliance with laws and regulations and guarantee quality.
Product inspection services, on the other hand, are about examining the little picture and are generally used to help manage existing relationships. On-site QC China inspection services require inspectors to visit the producer’s factory at any stage during manufacturing to monitor the process based on the requirement of the supplier or buyer. Inspectors focus on the client’s requirements.
There are four common types of on-site quality control inspections. These include:
- Pre-Production Inspection
- During Production Inspection
- Pre-Shipment Inspection
- Container Loading Supervision
Pre-Production Inspection ensures that raw materials and components meet specifications. During Production Inspection ensures that production is on schedule and meets quality requirements. Pre-Shipment Inspection ensures that finished products meet quality standards and are ready for shipment. Container Loading Supervision ensures that products are loaded correctly and safely, and the correct quantity is shipped.
In summary, having a good mix of audits and inspections in your China quality control inspection program is important. While factory audits focus on the big picture and help make long-term decisions, product inspection services focus on the little picture and help manage existing relationships. Performing factory audits before working with a new supplier and conducting regular audits can help improve efficiency, productivity, and minimize risk in the supply chain. On-site QC China inspection services provide a range of inspections that focus on client requirements to ensure that products meet quality standards and are ready for shipment.
4 Types of China Quality Control Inspection Services
China quality control inspection services play a vital role in ensuring that products meet the required standards and specifications. These inspections help to identify defects and problems early, which saves time and money. Here are the four types of China quality control inspection services most buyers choose:
1. Pre-Production Inspection (PPI)
A Pre-Production Inspection (PPI) is conducted before the production process begins and helps to assess the quantity and quality of the raw materials and components. The inspection ensures that the materials conform to the relevant product specifications. PPI is beneficial when working with a new supplier, especially if the project is a large contract with critical delivery dates. This inspection helps to reduce or eliminate communication between the buyer and the supplier on issues regarding production timelines, shipping dates, and quality expectations.
2. During Production Inspection (DPI)
During Production Inspection (DPI), also known as DUPRO, is a quality control inspection conducted while production is underway. This step is particularly useful for products that are in continuous production and have strict requirements. DPI inspections take place when only 10-15% of units are completed so that any deviations can be identified, have feedback given, and any defects can be re-checked to confirm they have been corrected. DPI enables the buyer to confirm that quality, as well as compliance to specifications, is being maintained throughout the production process. It also provides early detection of any issues requiring correction, thereby reducing delays and rework.
3. Pre-Shipment Inspection (PSI)
Pre-Shipment Inspection (PSI) is an important step in the quality control process. It is the method for checking the quality of goods before they are shipped. PSI ensures that production complies with the specifications of the buyer. This inspection process is conducted on finished products when at least 80% of the order has been packed for shipping. Random samples are selected and inspected for defects against the relevant standards and procedures.
4. Container Loading/Loading Supervision (LS)
Container loading and unloading inspections ensure that products are loaded and unloaded correctly. Inspectors supervise throughout the whole process and ensure that products are handled professionally to guarantee their safe arrival at their destination. This inspection usually takes place at the factory while the cargo is being loaded into the shipping container and at the destination once the products have arrived and are being unloaded. The process includes evaluating the condition of the shipping container, verifying all the product information, quantities, and packaging compliance.
In summary, China quality control inspection services help to identify defects and problems early, which saves time and money. The four types of inspection services most buyers choose are Pre-Production Inspection (PPI), During Production Inspection (DPI), Pre-Shipment Inspection (PSI), and Container Loading/Loading Supervision (LS). These inspections ensure that products meet the required standards and specifications and are handled professionally throughout the production and shipping process.
How to Start a QC Inspection Service in China?
What Preparations Are Needed to Launch Quality Control Inspection Services in China?
Launching quality control inspection services in China requires careful preparations to ensure successful outcomes. Here are some essential steps that need to be taken:
Product Specifications Sheet
It is highly recommended to provide inspection agents with a product specifications sheet. This sheet can be used as a quality checklist to ensure that all product requirements are followed. The sheet should include the following information:
-
Product requirements. To avoid confusion, product requirements should specify materials to be used, and specifications like weight and dimensions. It is essential to include a sample with the color for comparison. For electronics, labeling and markings like CE mark should be included.
-
Packaging requirements. An effective quality control checklist clarifies how the products should be packaged, including weight, dimensions, and labeling requirements like size, contents, and markings. Labeling is particularly important if the cartons convey your brand.
-
On-site quality checks and tests. To avoid non-compliance and quality issues, it is crucial to list the tests and inspections, outline tolerances, and specify pass/fail criteria.
-
Defect classification. It is used to determine whether the product passes or fails the inspections. Defects under the AQL standard are classified into three types – minor defects, major defects, and critical defects that should not be tolerated.
-
Constructive collaboration between all parties in a quality control chain is vital for success. You must outline how all parties will collaborate during the inspection and start by consulting your supplier and QC staff as you develop your QC checklist.
China Quality Check Service
To start a QC inspection service in China, you need to tell your inspection agents when to go to the factory and what China quality check service you want. The process works like this:
First, you will have an agreement with the supplier about the highest defective product rates, which means the percentage of the number of defective products cannot exceed these criteria.
Next, after the production is done, you hire the inspection company, and they will go to the factory to do the product inspection there.
Once they are done with the inspection, they will provide you a detailed inspection report.
To summarize, launching a QC inspection service in China requires careful preparation, including providing inspection agents with a product specifications sheet and outlining how all parties will collaborate during the inspection. By following these steps, you can ensure successful outcomes and avoid quality issues.
In Conclusion
What is the minimum you need to do?
To ensure product quality control, there are different steps to take depending on the situation. If purchasing a standard product made in China or another Asian country, it is recommended to determine finished product requirements, approve pre-production samples, and hire a China QC inspection company. For those developing a new product, additional measures are necessary, such as conducting supplier audits and quality control inspection services in China.
It is important to have a good mix of both supplier audits and quality control inspection services to ensure project success. By taking these steps, businesses can have confidence in the quality of their products and avoid potential issues down the line. Overall, investing in quality control measures is a wise decision for any business looking to maintain high standards and customer satisfaction.
