This has me a little worried since I exclusively vape HS tobacco flavors. A couple things come to mind. Did HS sell concentrated flavoring in the US prior to the grandfather date? I assume the answer is no but they are certainly a pioneer in this industry so maybe there is a hole there.
If HS tobacco flavors aren't grandfathered, would HS have the means (or desire) to go through the approval process for their concentrates? They are a huge player globally and I'm sure it will effect HS if they can't sell their stuff here anymore.
Lastly, does anybody really think there will be a shipping barrier or anything from China? Will stuff get seized? Sure. Will stuff get through? Lots of it. At least in my opinion. fasttech isn't going anywhere. They sell all over the world. They don't have the best track record for caring about anything other than selling stuff fast and cheap.
I'm ok with unflavored though. I vape it from time to time and like it quite a bit. I suppose I could do my own NET's but would much prefer to stick with what I already love and the ease of mixing it.
These are all thoughts that I also have and as you most of my hardware comes from fastTech and most of the flavoring I use other then my own extracts is HS. I wonder will the FDA flag these importers. Will FastTech do business under a different name if this happens. Will HS submit to FDA testing or market the products as food or fragrance ingredients. All valid questions. We have time before this is all phased in and I think through public pressure the FDA will need to lighten up on some aspects of this regulation after all the FDA has backed down or changed regulation guidelines in the past because of strong opposition. As I said this is all to new and only time will tell. I think the best recourse right now is to raise our voices and turn up the pressure on these federal and government regulatory agencies as well as our government officals.
