We have several machine tools shipping to Brazil from a bonded warehouse in Antwerp within the next month. We should be sending some retrofit kits along with them, which are already on the invoice, however these will need to follow along separately directly from Japan to Brazil. Could you advise how to avoid paying the duty on the kits twice? Do Brazil allow supplementary declarations to be made to reclaim over payments? Or is there a mechanism to pay in advance, and refer to the original invoice on the follow up movement?
