Hey Heir. Jonny or Kay can speak on paying any import duties (I’m also in the U.S. and have never been charged so I’ve got no clue).
As for tracking, the tracking only starts once it actually arrives in the U.S., which can take some time. At 11 days, you should see activity on it within the next few days, I’d wager. Most of my packages take 2-3 weeks to deliver.
Lately there’s been issues with some of the customs centers of rejecting snuff parcels. If that happens, Mr. Snuff should send you an email notifying you, so make sure to keep an eye on your spam folder just in case they reach out and it gets flagged as spam (which happens to some people).
