I believe that SI
juice - like almost all ejuice - is made in China.
I know that almost 100% of nicotine is produced in China or India [maybe a couple of other places outside the US] so even the
juice you buy that is made in the USA has Chinese produced nicotine, basically.
I actually have plenty of confidence in Chinese ejuice from well known companies. I know there are people that have their panties in a wad about Chinese products but ejuice is vaped all over the world that is made in China and I think that any of the well known juice producers care very much about their products.
