As already mentioned, Made in USA version was also available but nowhere near as smooth and good as German version. Generally Castrol makes in the US Group III products that are not on par with European versions.
Current 0W30 is Made in Belgium, and it is still best and smoothest Edge available (I use it) and the reason why it lost on popularity is that 0W40 goes for $26 for 5qt in Wal Mart and 0W30 goes for $60 for 6qt box on Amazon.
Current Castrol A3/B4 0W-30 and 0W-40 have very similar PAO content -- both 25 - 50% according to the MSDSs, so perhaps PAO being roughly half the base oil.
Current 0W-30 is blended in several locations, including Italy, according to the MSDSs, where there is a manufacturing-country code somewhere.
I thought both products were fully PAO-based
until a few years ago; so, there wasn't much change from the
green formulation of fifteen years ago. (Happy St. Patrick's Day, everyone.
)
Full-SAPS A3/B4 formulations are becoming less and less popular and being replaced by mid-SAPS (C3 (3.5 - 3.6 cP) and C5 (2.6 - 2.7 cP)) formulations. This is
what Trav had said:

They are keeping the 0w40. If you were using the 0w30 just use the 0w40, your engine wont know the difference.

I don't think the OP asked about the history of Castrol A3/B4 0W-30. My post here was to explain what is currently available. Then another person and you talked about the history, which is fine.
We know that, we are using this product forever.
1. Current 0W30 is Made in Belgium and was never made in Italy. Castrol does make a lot of stuff in Italy and Austria especially.
2. Current 0W30 is not as popular bcs. of price, not A3 formulation. It is expensive and 0W40 is still really good oil, so people buy that. Castrol 0W30 A3 is still pushed in the US by Castrol. So far C3 is not being offered, who knows when or if they will offer it.
3. PAO content was changed in those oils last year. Until 2019 it was above 50%. However, both 0W30 and 0W40 are still exceptional oils and pretty much better than anything else out there when it comes to Euro cars.
