Reliable "Country of Origin" Search in Web Shop?

Recently I was quite delighted to find out that galaxus.de has a "country of origin" filter. The delight quickly faded when I realized that it was quite unreliable, e.g. one size of a USB stick was made supposedly made in Germany while another was supposedly made in China (which I found quite unbelievable). To be fair, they do write "Specifications may include unverified machine translations."

Does anybody know of a (tech or other) online shop where this works? Or tipps how to quicker navigate real and fake/mistaken "country of origin" labels?
