Can you explain the flow of goods? What incoterm applies on your supply? Who arranges the import?
Whatever, there is no reverse charge possibility to any non EU private person possible. If the goods are imported in the name of C, the latter must account for any import VAT and or duties if any. Shipments under a certain level are VAT/duties exempt.
Where is the EU company located. In which Member states are the goods imported.
To be able to give you some clues I need a lot more information.
