Chain-Tail's Quality Research Team offers reliable experience and creative ways of thinking. We are constantly putting forth new technology and testing new products including machines and experimental molds. All products all undergo extensive checks under the ISO 9001/2015, and are 100% guaranteed for quality, safety and zero defects before they leave the factory. In addition, Chain-Tail instituted RoHS standards for all of our products in 2005 as a part of our green policy on protection of the environment and the earth around us.
