Poland has become one of the manufacturing floors of Europe, and a great deal of what is built there is engineered or sold in the United States. Automotive components, appliances, electronics assembly and machinery all run to schedules set somewhere else, and when a line stops the missing item is small and the cost is counted in production hours.
The second driver is services rather than goods. A very large number of American companies run shared service, engineering and software operations from Kraków, Wrocław and Warsaw, and that produces a constant flow of executed originals, corporate documents and prototype hardware between the two countries.
The third is that Poland is a customs entry point for a wider region. Goods cleared into Poland are in free circulation across the Union, and for consignments continuing into central and eastern Europe the road leg from Warsaw or Katowice is frequently shorter than the alternative flight.
