All SUNLIFE products are manufactured by IS9001:2000 and HACCP:2002 internationally certified factories. In order to guarantee the quality and safety of each batch of products, we test not only for the quantities of the various elements contained in each batch, but also for pesticide and heavy metal residues. We also regularly make sample tests for residues for 180 types of Western medicines. Finally, our products come with product liability insurance (max. NTD30 million) to ensure consumer safety.
