I have been buying from and selling to Brazil for the last 15+ yrs ...
Buy leather from Brazil for sale in the USA and it is a process that I am constantly tweaking trying to make everything work.
Sell exotic skins to Brazil and it is a HUGE freaking headache but the profit margins are excellent.
Brazilian businessmen always have a "book of excuses" that they will reach for whenever the situation is not right -- and the situation is never right. Expect this and plan for it.
Also, being a big company means you will have help the "brazilian" no matter how big and well off they are.
