Country of origin is China. However, I found on my trailer that all of the components are all standard sizes, for which replacement parts should be readily available here in the U.S. When I bought this folding trailer, I was also considering the lighter version of this trailer sold by Northern Tool (the one painted red), and found that many of the components that on that trailer are the same as this trailer, and those components could be bought individually from Northern Tool too. Regardless, I don't think I, you, or anyone else buying this trailer will find it difficult to get new tires, rims, couplers, etc. for this trailer in the future. It's pretty clear that this trailer was engineered and built with U.S. standards in mind.
