With so many vehicle variations, you need a lot of filter variations. It does not make economical sense to make all possible filters (certainly in excess of 10,000) in every country.
We have a lot of Asian made cars and European Volvo trucks here, so from Donaldson I get a lot of British made filters for the Volvos and a lot of Indonesian filters for the Asian cars. Since Italy is the king of air compressors, a lot of the compressor filters are made there. Out of 16 countries, I get more than 50% from the USA. It really depends on where the car is made and how many of them are in any given country.
There is one filter I that I need 800 per month. but it still isn't enough volume for them to make in a second country. Still makes sense for them to send it from Indonesia to Mexico for a final destination of Bolivia. So I imagine in the US you would also get the Indonesian filter for that application. BTW, it is a very nicely built filter.
I think quality depends more on the Brand and their controls than the country.
