You just need to imagine that for every step of the way (say manufacturing, packaging and transport) there's a bribe (not necessarily to avoid a justified fine) for whatever official was supposed to take care of it. Corruption in South America is pretty much a way of life
No details. It is illegal for Canadian citizens to bribe workers of foreign governments. So, of course, I was able to do everything without ever exchanging money with a foreign official. But, if one were in a position to do so, I imagine things would have proceeded in a much more efficient way.
