Why not Rech Chemical exports zinc sulphate via Shenzhen?

Rech Chemical Co. Ltd once exports zinc sulfate mainly via SHENZHEN to all over the world. It is well known that Chinese's coastline stretches widely across north and south, which is good for coastal cities to form natural shipping harbors. 

There have been some international ports as Shanghai port, Shenzhen, Qingdao, Guangzhou port, Tianjin port. Those ports all are undertaking thousands of loading and shipping businesses. As a factory Hunan located in the middle territory of China, why choose an inland port for loading instead of such international ports, and choose?

There are three reasons as bellow:
Firstly, because of its special product feature, zinc sulfate is regarded as Dangerous Goods Nine, by the European Union, and also listed as dangerous goods by Shenzhen Maritime Safety Administration. Zinc sulfate could be exported only as dangerous goods in Shenzhen but as general cargo in Huangpu. So, the shipping cost as dangerous goods surely be high than the latter.

Secondly, it’s bad for controlling the shipping cost because handling fee of Shenzhen port is much higher than those of Huangpu.

Thirdly, our factory locates closely to Huangpu than Shenzhen and cargo’s transportation cost is much lower.

This is why we mainly choose Huangpu to export zinc sulphate.
