Why Can We Always Ensure Excellent Quality

Quality Control

Riel Chemical Co., Ltd. is committed to providing customers with high quality chemical products that meet international standards. We adopt a strict quality control process to ensure that each batch of products from raw material procurement to finished products are strictly tested and monitored to meet the high standards of customers.

1. Inspection of raw materials
When purchasing raw materials, the quality inspection department will strictly screen suppliers and select raw material suppliers that meet international standards. After each batch of raw materials arrives at the factory, it will undergo strict physical and chemical properties testing to ensure that its purity, composition and quality meet the production requirements.

2. Production process monitoring
In the production process, we use advanced automation equipment and precision control systems to ensure that every step is operated within standard parameters. Technicians monitor key parameters such as temperature, pressure and time during the production process in real time to ensure that products meet established quality standards.

3. Random inspection of intermediate products
Intermediate products are sampled at different stages of production, including purity, composition and physical properties. The intermediate test results will be used to adjust the production parameters to ensure stable quality of the final product.

4. Finished product inspection
After production is completed, each batch of finished products is thoroughly tested, including purity, composition, pH, solubility and many other indicators. We work with third-party testing organizations to independently test our products to ensure they meet customer specifications and international standards.

5. Package and label check
After the finished product passes the inspection, it enters the packaging process. The packaging department ensures that the packaging of the products is complete, well sealed, and accompanied by accurate labeling information, including product name, specifications, lot number, etc., so that customers can trace the source and quality information of the products in subsequent use.

6. Quality review before delivery
Before shipment, the quality inspection team conducts a final review of each batch of products to confirm that all quality documents and inspection reports are complete. Qualified products can be shipped from the factory to ensure that every product delivered to customers meets the highest quality standards.

7. Customer feedback and improvement
We attach importance to customer experience and feedback, and regularly visit customers to understand the performance of products in the use process and collect suggestions for improvement. Customer feedback will be used to improve quality management processes and production processes to continuously improve product quality.
