Larry,
I guess I didn't pay attention to the country of origin, but I used the stuff in the 40 lb bags from Sam's last summer quite a bit. Large pieces and a bit of popping at the start, but overall very nice lump. I didn't find it any more overpowering than Rancher or Stubbs briqs. Plus, the price was fantastic ($14.99). This year they are carrying Best of the West Mesquite. I think I'll pass on that stuff based on other reviews I've read. I would buy the Frontier all summer if I could get it.
