From our profile, you may see us as a seller not manufacturer because we use business license of our trading company for ALIBABA service. In fact, we are a real manufacturer.

We started business as a trading company with SEP brand which is influential in Zhejiang,China. As our market share grow, we established our own filter factory. We welcome new and old customers to visit our factory which are close to Shanghai.

We choose this factory address because it's not far away from shanghai and also can cut our costs. But we didn't combine our trading company to factory because of our boss and his family in zhejiang.

We mainly produce air filters and some parts of Agricultural, Industrial, Forest and Grasscare equipment, Powersports and Automobiles. And we also source other small engine parts for customers. What we want to do: Make the Best Parts.
