Tariffs range between 10% to 50% on the declared value, or $80 to $200 per parcel. Goods above $2,500 are subject to a Merchandise Processing Fee and additional formal customs checks. Processing delays and increased costs were incurred immediately, but now, a growing number of nations have decided to simply discontinue parcel service.

In Europe, the United Kingdom, France, Germany, Italy, Belgium, Austria, Switzerland, Denmark, Sweden, Norway, Finland, Czechia, the Netherlands, Spain, Poland, Portugal, and Ireland suspended services. In the Asia-Pacific, Australia, New Zealand, India, Japan, South Korea, Taiwan, Singapore, Thailand have halted services as well. Canada has also curbed its mail exports. All of this has been implemented at the federal level, whereas previously, individual postal carriers determined whether or not they would service the US.
