Yulong Biotech strengthens quality control over the source of matcha raw materials through close cooperation with high-altitude tea plantations in the Three Gorges and Shennongjia regions. By implementing certification systems for raw material production at the base, certification for processing procedures, and rigorous testing conducted in our own testing facilities, we ensure effective control over each batch of products to guarantee product quality. We consistently strive to preserve the natural flavor and quality of the raw materials to the highest degree.
