Our Operations

We operate two manufacturing plants in China.

  • Dongguan, Guangdong - 3 km from Port of Huangpu, China, 100 km from Hong Kong
  • Zhuzhou, Hunan - Largest railway junction in South China

The plants are strategically located close to major transportation hubs. This allows our products to be transported to locations worldwide regularly and frequently. The two plants operate three independent production lines, providing maximum supply stability and reliability.

All two plants and all three lines standardize on the same efficient sodium formate for sodium hydrosulfite. Whatever we learn from one production line can be adopted everywhere else. The economy of scale allows us to be the lowest cost producer in the world.
