Definition of Quality Control and Its Role in Supply Chain Management
Quality control (QC) is a process that ensures that products and services meet certain predetermined standards or specifications. Inspection services are crucial in import and export trade. They involve inspecting and accepting the quality of supplied goods, as well as other relevant aspects of the order and sales contract based on the client requirements. The aim is to ensure that the supplied goods meet the requirements of the order contract and any special requests of the buyer.
Those who perform inspection work are commonly referred to as QC (short for Quality Controller). QC inspection activities are known as inspection. There are three types of inspection services based on the QC client: first-party inspection, second-party inspection, and third-party inspection. First-party inspection is arranged by the manufacturer themselves, second-party inspection is dispatched by the customer company, while third-party inspection is conducted by external inspection agencies commissioned by the customer.
In supply chain management (SCM), QC plays a crucial role in ensuring that the products and services delivered to customers meet their quality expectations. By implementing a QC system, companies can identify and correct quality issues before shipping, thereby reducing the risk of customer complaints and returns.
Effective QC requires a systematic approach that includes setting quality standards, developing quality control plans, implementing quality control procedures, and monitoring the results. This requires collaboration and communication among all the parties involved in the supply chain, including suppliers, manufacturers, and buyers.

Quality Control Classification
1. Pre-Production Inspection:
Inspection personnel conduct random sampling inspections of raw materials, initial processed products, and components produced during the production process.
2. In-Line Inspection
Inspection personnel conduct inspections of semi-finished products on the production line, checking for discrepancies and deviations, reporting to the factory, and providing effective methods for correcting errors and deviations.
3. Final Inspection
Inspection personnel check the quantity, process, function, color, size specifications, packaging, and other details of the goods before delivery (generally 80% of the products are packaged after 100% of the production is completed). The sample drawn method is carried out in accordance with international standards such as ISO2859/NF X06-022/ANSI/ASQC Z1.4/BS 6001/DIN 40080 and follows the buyer's AQL sampling level.
4. Factory Evaluation- Assessing Manufacturing Facilities
During a factory evaluation, an auditor assigns inspectors to inspect the working conditions, production status, facilities, manufacturing equipment, manufacturing methods, quality assurance management, and personnel of the production enterprise. This evaluation is conducted according to customer requirements, and the resulting explanations and opinions are shared with the customer. The factory evaluation not only helps customers investigate potential quality accidents but also provides valuable improvement suggestions for the factory.
5. Sample Size and Acceptable Quality Level (AQL)
Inspecting 100% of the goods is the safest way to ensure quality, but it can be time-consuming and expensive for large batches. That's why finding a balance between product quality risks and QC costs is important. This balance point is called the "sample size." During the sampling inspection process, QC needs to determine how many defects can be found and what level of defects can be accepted or rejected. This is known as the "acceptable quality level" (AQL).
6. Defect Classification Made Simple
During the inspection process, defects are classified into three levels based on their severity: critical, major, and minor. Critical defects are those that can potentially harm the human body or violate laws and regulations, such as sharp edges, corners, and electrical leakage. Major defects are significant functional or appearance defects, such as poorly printed logos or insulation cups that do not insulate. Minor defects are minor appearance defects like slight scratches or minor printing defects on the surface. Experienced QC personnel can usually classify defects based on these principles. However, some customers prefer to create a Defective Classification List (DCL) to ensure that all participating QC personnel understand the defect classification. This list includes all defects related to the product and indicates the assigned defect level for each one.
Why Quality Control is Important in Supply Chain Management
1. Ensuring Compliance
Quality control helps businesses verify that the goods supplied by the supplier meet the quality requirements specified by national laws, regulations, or relevant standards. This is essential to ensure that the products meet the required safety, health, and environmental standards.
2. Preventing Delays and Defects
Timely detection and prevention of delivery delays and product defects can save businesses from potential losses and reputation damage. In case of any issues, emergency and remedial measures can be taken immediately to minimize the impact.
3. Reducing Consumer Complaints
Poor quality products can lead to customer complaints, returns, and loss of commercial reputation. By ensuring quality control, businesses can reduce the risk of such incidents and maintain a positive brand image.
4. Avoiding Compensation and Penalties
Selling inferior products can lead to legal consequences, such as compensation claims and administrative penalties. By implementing quality control, businesses can reduce the risk of such outcomes and protect themselves from financial losses.
