What is our quality control process?

Through strict quality control process, we ensure that every product received by customers is guaranteed.

1. Supplier Screening and Evaluation

We implement a comprehensive supplier evaluation system to ensure quality from the source.

Qualification Review

We will review the supplier's business license, production license, industry certification (such as ISO 9001) and other basic qualifications. We will also evaluate the supplier's production capacity, equipment level, technical process, etc. through field visits.

Quality Technical Requirements

We will work with suppliers to formulate the "Product Specifications", clarify key parameters, inspection standards and acceptance procedures, and provide drawings or technical agreements for special materials as contract attachments.

Contract Risk Management

In the contract, we will stipulate quality breach of contract liability (such as return, compensation), dispute resolution mechanism and after-sales service requirements. For high-risk procurement, add third-party quality inspection or insurance clauses to share risks.

2. Procurement Execution Monitoring

We maintain strict oversight throughout the entire production and delivery process.

Production Quality Tracking

Carry out surprise inspections or on-site supervision of key nodes (such as raw material storage and semi-finished product processing). Require suppliers to provide production records (such as process parameters and quality inspection reports.

Logistics & Delivery Control

Supervise packaging and transportation conditions (such as moisture-proof and shock-proof) to avoid quality loss during transportation. Check the arrival quantity, batch number and contract consistency, and record abnormal situations.

3. Acceptance and Quality Traceability

We employ systematic inspection procedures and maintain comprehensive quality records.

Graded Inspection System

Category A materials: full inspection or commissioned third-party laboratory inspection. Category B/C materials: sampling inspection in proportion, retaining samples for reference.

Quality Issue Resolution

In case of unqualified acceptance, the return and exchange procedure will be initiated, and the supplier's responsibility will be traced simultaneously and rectification will be made within a time limit.

4. Supplier Performance Management

We continuously evaluate and improve our supplier relationships through data-driven insights.

Dynamic Evaluation System

Regularly score suppliers from the dimensions of quality qualification rate, response speed, after-sales cooperation, etc., and classify suppliers. Eliminate suppliers with continuous unqualified scores and optimize the cooperation list.

Digital Management Tools

Use ERP or procurement management system to achieve online traceability of the entire process from demand planning to acceptance data. Analyze high-frequency quality problems through big data and reversely promote supplier process improvement.
