The topic of my dissertation is The Asian Port Doctrine with Respect to South African Port Pricing

I am making contact with freight forwarders who are involved in the facilitation of some trade with economies like China, Taiwan, Korea, Japan, Singapore and other Asian archipelago. The object of this exercise is to get an idea of the type of costs incurred by container ships that call into the various ports of these economies.

I cordially ask you refer me to sources that may lead me to acquire the tariff strategy and methodology used in the Far Eastern ports and, quite possibly, the policies underpinning those strategies.
