After much hassle caused by Brexit-related changes in procedures for importing goods from the UK to the EU, we finally managed to ship some of the equipment from my previous lab to Warsaw. The equipment was kindly donated by the University of Edinburgh.
The procedure was quite complicated. Big thanks to Ania Jasczak and the company Gosselin Moving who have been instrumental in arranging the shipment.
We now feel experts in international shipment. If anyone faces a similar problem, we will be happy to provide advice.
