If you read my above post you can see that we as ADOX cannot replace them. But we can assure the supply of our own branded chemicals and this is the purpose of this thread.
actually your initial post is weird because the chemicals you manufacture yourself are for BW but not C41 RA4 you sell on Fotoimpex. These are only in part from the factory in Norderstedt. Fuji x-press kits are produced in Belgium, i don't know about the raw chemicals used in their kit, but is it Norderstedt also? and I always wondered where Hans O. Mahn buy their Digibase/Compard set, I was thinking of Norderstedt or of Calbe but never succeeded in getting an answer.
I appreciate a lot your dedication to analog photography but on the chemical side of reagents for developers, I can make my own Rodinal ersatz at home, and I buy: from Foma, from Kodak (HC110), and mix my owns from metol, hydroquinone, phenidone, natrium and kalium sulfites and sulfates, EDTA, bromide, etc, found at different places like France, Poland, Ukraine, Russia.
Besides, with a registered one-man company just for that sake (in Norway it's a 2000kr one-time fee) , I can get most chemicals from Sigma-Aldrich and Avantor local sales,excepted maybe the trickier CD3. Unless Sigma-Aldrich is going down no problem for BW chemistry.
so I had mixed feeling when reading your thread: for C41 I am very affected by Nordersted closure only if they did provide raw chemistry to Fuji and to Hans O. Mahn. Yet my preferred is the Fuji kit. I hate the Tetenal blix stuff and want the bleach and fixer separate.
But since you don't manufacture colour kits, then no difference in this areas.
And for BW chemicals well, as I have summarized.
