Well, fill your boots, then. If it has worked for you, then fine. If not, you can certainly take this advice for what it's worth to you. But in terms of rules and regulations and how to deal with places such as Australia or Portugal, I'd be shocked if they can't give you some advice.
I can't tell you what percentage of stuff goes into your product, and I'm not sure that any of these organizations can. It's your product, and that is proprietary, when it comes to the requirement for you to share it.
Anyway, that's the advice, for what it is worth.
