duralast ball joints vs moog

Regarding the Made in USA versus the Made in China Moog parts, do the parts have USA or China on the part itself or just on the box?

After following this post I went and looked at some Moog balljoints I bought recently, it says made in USA on the box but not on the part.

I also recently bought some Moog/Precision u-joints that say USA on the part and made in USA on the part.

Just wondering how you're identifying the source of the parts.
