Not exactly Charlie, about a year ago, many Chinese have been using other ship from facilities, so that when it’s entered into Customs, it can be Singapore, Philippines, Taiwan, Israel, EU, or even within the multitude of US drop ship facilities. On the surface your correct with regards to the UPU
You need to realize that China has inroads to all of Africa, Canada, Mexico, all of South America, India and here in the US, the majority of sellers are also purchasing from China one way or another.
Just yesterday Chinese Guns (Assault Weapons) were discovered to be imported in Los Angeles, you need to factor that they have been imported many times over, gaining confidence that truck loads of guns would safely arrive to it’s destination. All the major shipping containers, vessels are owned by China, and those that previously were owned by the British, were sold to them. You tell me which Shipping Vessels are owned by the US?
So yes, let me live in my dreams and swallow the news as it suits me.
