New product alert!

Hey everyone, I’m not sure if this has come up before, but here’s what’s on my mind...

Let's say I wanted to introduce a few new products that aren't really available here in the States. What would that actually look like from a procedural standpoint? Like, what does it take to get a product onto shelves? I don't mean I'd be out there hawking them myself from a roadside stand—more like setting up some kind of arrangement where I get a percentage or a commission or something. How does that whole thing work? If anyone here has actually pulled something like this off, I'd love it if you could walk me through the process and let me know if it's even realistic...

Just wave a magic wand and everything changes...😉

Look, you’ve got to actually specify what product we’re talking about here—is it food, clothing, some kind of consumer good...
Give me some actual, concrete details first.

So, there's this snack from the States that’s everywhere else—except here. I guess we're talking about some kind of chocolate bar, maybe something like a Twix or a Mars bar... how would you even put it?
