Sorry for the cross-posting. I hope someone can offer some guidance through experience for my situation. I have been waiting to ship back some artwork we borrowed for an exhibition to international artists for close to a year due to the Covid-19 pandemic which resulted in a force-majeure between the US Post Office and corresponding post offices in other countries. The artists are anxious to have their work returned and I am anxious to get my storage back. I was planning on using the US Post Office International shipping whose rates are substantially cheaper than UPS or FedEx, and due to the amount of work that I need to ship the UPS/FedEx route is beyond the amount budgeted for shipping/drayage. 
I have been putting off sending the work back due to the force-majeure which means neither postal office can guarantee delivery in a timely manner and I don't want artwork sitting in a processing facility longer than necessary. 
So, has anyone been shipping internationally via US Post Office services, and what has been your experience? I would like to be able to reassure the artists and my boss artwork can be returned safe and securely.
