What is the new Infrastructure Impact Development Tax?

Question

I have sent some paving to a client in Ngelrumud and have been asked to pay Infrastructure Impact Development Tax. Would anyone know whether this would need to be paid in the local currency or in Pound Sterling?

It seems that customs in Ngelrumud have taken the paving into customs until this is paid.

How does one go about paying this and at what percentage does one have to add on for this particular tax?
