As was pointed out, Agfapan APX-100 is not a product on the market now. It was the original APX-100, previously produced in Leverkusen, Germany by (the real) Agfa-Gevaert. Agfaphoto APX-100 (the same product as the last Agfapan version more or less) was briefly sold by the original division of Agfa-Gevaert, from when it was spun out in 2004 until bankruptcy in 2005. Lupus bought the rights to use Agfaphoto branding on their line of film products sometime between 2005 and 2011.
Then, briefly, Lupus imaging sold this *same* original, real stock as Agfaphoto APX-100 in 2011-2013 using stored/frozen jumbos that were confectioned for them by Ilford/Harman in England. These boxes look *identical* to the current offering, but without "New Emulsion" labels.
The last of this stock was sold off by about 2015. By this point Lupus had begun shipping Kentmere 100 in the exact same packaging, with the exact same branding, with only "New Emulsion" label showing the difference. To confuse the matter, many sites and shops continued to sell it like it was the same film. Some did not even update photos of the packaging. Remember, Harman was already confectioning the earlier stock, so switching to confectioning Kentmere 100 instead did not disrupt supply lines in any way.
Now, since about 2014-ish the stock available as Agfaphoto APX-100 is Kentmere. A good film. Not the same stock at all, though.
The nearest cousin to the original APX-100 available in the last decade was ADOX Silvermax 100, which used much original Agfa chemistry in its formulation. When those original chemicals ran out, it went out of production finally, forever. About 4-5 years ago.
