Will there be any? If it's a syrup and it's supposedly DEA-based, it's not going to oxidize very readily anyway, since aerial oxidation won't play much of a role in the context of the syrup itself. When it comes to the working-strength developer, I still suspect that a DEA-based adduct may be present even though the SDS doesn't explicitly mention it, and that this acts as a sulfite donor in the working strength developer.
The return of the Syrup: HC-110 in the water-free version manufactured again

That would be Ilfotec HC.

For comparison, the sulfur dioxide adduct aka diethanolamine bisulfite was present in Ilfotec HC in 2015:
However it was absent in Ilfotec HC in 2022:
Maybe it was quietly dropped and unnoticed (possible) or the listing rules were changed.
So the Adox HC-110 pro syrup may not have any sulfite either.

I'd have thought the SDS would have to mention either what's present above some tiny percentage in the final product, or what goes into the mixer above some tiny percentage -- so if an adduct, it would have to say something like "Diethanolamine/SO2 adduct -- X% to Y%" or it would have to include "SO2 Z% to A%". Then again, my knowledge of SDS-speak is limited to the annual safety training from my employer...
That's one of the things I don't know for certain about SDS. I'd think it does -- after all, there are safety considerations to using it, safe ways to handle it, etc. At least in food, sulfites are considered potential carcinogens -- or at least used to be.
Are you sure you're not confusing them with nitrites? Sulfites are common preservatives in food. E220 through E228 are the EU identifiers for sulfites in food. It wouldn't surprise me in the least if the inclusion of sulfites, especially in single-digit percentage amounts, does not need to be declared in an SDS. IDK for sure though.
Not completely, no. And if sulfites need not be declared below some figure that would be reasonable for the diethanolamine adduct, there we have it.
I was under the impression that the ingredients do react when mixed and the MSDS may have to list what is ADDED to the mix, and not what it in the bottle when it turns up at the Photoshop.
that mans that if I were to try and optain it, it would require a Canadian Distributor as if only availabel from a US based distributor, they would likly not be in a position to ship it again to Canada. I would perfer to have the syrup formula as the watery US made formula (both under the Kodak name and the Legacy Pro Name) seems to throw off hard white/clear crystals. which can't be good for consistancy.
is their any thought to providing this in Canada?
Nope, it shows up in the 2000s HC110 MSDS.
I think the listing rules changed. One MSDS for Rodinal was very detailed, no < or > rather precise percentages to a decimal place, this was Compard or another company not Agfa. There was also a spell a few years ago where Australian MSDS sheets gave far more information than others
Sulphites (inc Metabisulphite) are only shown above a certain level. I don't know what that is now. Ilford's current MSDS don't list all the chemicals that are at low levels any longer.
You often see "This product may contain Sulphites" on wine bottles and food packaging, the levels are typically minimal, but enough to trigger an asthmatic attack in high risk people.
Surprisingly Microphen Part A contains 30-40% Sodium Metabisulphite, however in the final mixed stock developer it and the Sodium Sulphite of Part B aren't listed in the Mixed stock MSDS.
It maybe there are different criteria for powders and liquids.

If/when it becomes available in the USA, and with the tariff situation who knows if it can happen, I'll buy a bottle, the water based stuff never enticed me for a trial. We'll have to see.
I will buy a bottle just to compare with some vintage HC-110 I have in my "cellar". 
True, and so is DD-X.
It contains N-Methyl-Ethanolamine-Sulfite with about 50g/l.
That is certainly enough sulfite.
I am not a fan of HC-110, because I have always got better results with other developers.
But I highly appreciate ADOX activities and enthusiasm to react to specific demand from customer groups. And making these customers happy.
That is excellent, customer friendly behaviour!

Thanks, the changes in rules for listing in msds did not get much publicity and I was mistakenly expecting something like the msds for a version of the early Kodak syrup.
It would be interesting if you are in a position to disclose a source for your above info, but maybe not.
If I may be incredibly pedantic, I keep seeing references in this thread to the "MSDS" for the 2019 version of HC-110, the new Adox version, and a few other products.
Again, being incredibly pedantic about this, but can someone reference where they are finding an "MSDS" for these products? I have not seen any such document, nor frankly should one exist.
The SDS is readily found, but no manufacturer in 2025 should be publishing an "MSDS."

As I said, there is no MSDS for this product...
