As far as I am aware, Duty is paid at the point of purchase, should regulation require. So... Duty for an item made in country C, is paid for by the company, in country D, which makes the contract and receives the goods.

The contract between the company in country C and the company in Country D, is complete in payment and excise, any further ongoing is no business of country C..
