About Us

With over 10 years of development in industrial ethernet switches and agricultural machines, teams from Yunjushang (Shenzhen) Industrial Co., Ltd. (YJS) set up their base in Shenzhen with two business divisions.

For agricultural machines, the professional team is based in Chongqing and works on general machines such as gasoline engines, generator sets, water pumps, micro tillage machines, plus garden machinery. Rice harvester and construction machinery are named on the source About page; they are not listed as catalog SKUs on this site.

For industrial ethernet switches, YJS teams own four brands in China. The YUN series switch is for the international market. The About page states CE, CCC, RoHS and FC certificates for that switch business. Those marks are not attached to individual agricultural SKUs unless a product page shows them.

The same page says the company has exported to America, Africa, Europe and Southeast Asia, above 10 countries. The spirit written there is “quality-oriented, excellence” and “power-driven life”.

Gas-pump product pages also say the company was established in 2005 and the gas-pump line has been developed since 2008. Both statements are kept as published; they are not merged into a single founding year.
