Is it "customs" or "customer" ?

And what is "Ä°stabul HaydarpaÅŸa "?
Can't that be translated?

HaydarpaÅŸa Terminal is a terminus main station of the Turkish State Railways.

Ä°atanbul HaydarpaÅŸa is a proper noun so it cannot be translated. It's a terminal name.

Customer means "client" but here they mention about custom/customs.

delivery is missing teslim= delivery

should be:
customs delivery price

price of the product :$100
delivery place :Istanbul HaydarpaÅŸa customs

sayın yetkili is not translated.
