Quality inspection process

Component inspection is the top priority of our quality inspection process.

In order to ensure that our customers are provided with high quality products, our quality inspectors conduct a 2-stage inspection of 100% incoming parts. We can also provide a higher level of testing to provide a reference for our customers.

Packaging transportation standard

inventory management

HJC provides a third-party warehousing and professional IT inventory management software for customers to achieve seamless docking. The ownership of parts can only be transferred when the customer uses parts.

HJC's incoming parts have undergone rigorous inspection, and the products are stored in standard anti-static, anti-humidity, anti-high temperature, and the stock are regularly tested to make the parts safe.

Packaging out

The parts are tested for performance during shipment, and the packaging must be waterproof, moisture-proof and shock-proof. At the same time, HJC cooperates with a number of international first-class freight companies to ensure that the parts of first- and second-tier cities can be delivered at that day, and arrive the next day. The goods of third-tier cities and remote areas can be delivered at that day and arrive within two days to ensure that customers can receive our products in time.
