I think Russia is a special case, and perhaps one should not generalize based on shipping to and from Russia. For what it's worth, I have experienced no serious delays receiving small packages of capacitors and the like from Russia or Ukraine, purchased from eBay vendors, arriving in the US via USPS. Moreover, when I have to ship from my location to anywhere else within the USA, my first choice by far is US Priority Mail. I only use UPS or Fedex if the box is too big or too heavy for USPS. And I have had only one problem, which was probably my fault, a capacitor came loose in a preamplifier that I had modified by installing physically large capacitors that weren't properly secured.
I am not sure what you meant to say, Luis, about accepting liability, but have you ever tried to collect for loss or damage, from UPS or Fedex? I have, with zero responsiveness and no compensation for damage that was clearly due to mishandling. Both companies are adept at pointing out packing errors, real or imagined, and they alone make the final decisions about compensation. (Not referring to the incident described above which occurred at the hands of USPS, was my fault, and was easily fixed by me at no cost except a little time.)
