I reached out to Liland. Both the stainless and carbon steel version of these tanks are made in Taiwan (which is fine in my book) but they are also currently looking for US-based manufacturing for them.
I wasn't aware of the origin, but I coughed up the $$ for stainless out of caution because of ethanol/water in gas these days. What I can say is that it was a quality part and was an easy fit/install. Stainless seems excellent quality. I'm running it bare on my daily driver and it looks nice and shiny under there.
