Wharfage refers to the charges that are applied when we use the wharf to load or unload the cargo.
Wharfage charges are collected by the port authorities to use their facilities and services in the ports.

The port authority enjoys some flow of revenue through these charges.
There are three important considerations which are important in wharfage pricing policies: the flow of costs, the flow of benefits, and the flow of revenue.
The revenue that is generated by the user’s benefits finance the operation of the port
The port authority cannot charge more than acceptable market value.

If they try to charge cargo owners unreasonable amounts compared to the benefits that are offered by them, then the flow of cargo will dry up either by the ceasing of the trade or traders will switch to using other means of transportations.
If port operators try to charge too much to the ships then they may not call.
Wharfage can be calculated in terms of revenue tonnes loaded or unloaded.
Here are some of the sample wharfage rates for carriers.

Port of Boston:- It will cost around 50 USD;
Port of Houston:- It will cost around 70 USD;
Port of New Orleans:- It will cost around 75 USD.


Wharfage charges are paid by customers who are interested to import or want to get goods by the means of sea transportation,

the agent settles the terminal charges before the departure of the goods from its side so that there is no problem after the goods arrive.
Technically speaking, these are different from terminal charges and container handling charges for.
Wharfage charges only covers the fees levied on the vessel operator for allowing the passage of cargo through it.
Hence, it does not include other port operations costs like loading, unloading, demurrage, detention, sorting,labelling or storing.
After the goods reached their destination, they can usually be kept at the port for 5 to 6 days without any additional cost. This can be different when different agencies are interested in the goods.
When the deadline for removing the cargo exceeds, an additional charge may be applied before goods can be released.
