I checked once more the invoice and this is what it says:
Just got this from Aerosense. Seems like some suppliers are going for a world record
Is all TKS fluid equally effective?
From the MM for my system:
Some fluid is incredibly pricey and I wonder how anybody is going to pay that. Adams Aviation in the UK are offering a DTD 406 fluid for £1374 plus VAT and delivery, for 200 litres.
The best offer I found is “Wittig Umweltchemie”. Have purchased 400 Liter at substantially less than 4 €/ltr., incl. packing and freight to CH, excl. VAT.
Chemically the stuff is all the same.

The offer I got from them was higher than UltraBlue. However, it doesn’t have to mean anything the prices go up and down and I ordered 100 litres in 5 l cans.
Ultrablue IS Wittig…
These are a UK company.
Do any of their products work for you? I’m sure delivery would be easier to sort if it does.

Then I mixed them with someone else 
Got this from Kilfrost
Not sure how big a “drum” is but I asked for 200 litres.
