There are thousands of different sizes of filters used in the world. For the most part I see them coming from part of the world where that car or equipment is generally sold. The major filter makers have plants to serve that market and them import and export to balance their needs. 40% of what I'm getting from Donaldson is made in Mexico, another percentage is USA made, another percentage is European, etc. My truckload shipments all come from one distribution center (although the paperwork is 100 pages).
