I talked to the peroxide division of FMC a few years ago. I guess they sold
it and it is now called PeroxyChem. At the time they didn't regularly
operate their HTP plant so you had to pay to restart the production line.
Not sure if that is still the case now.
I know some people who have purchased small quantities from XL-Space
somewhat recently. I don't what his production ability is.
The real kicker with HTP is the shipping. FMC had a special conex container
and a special truck to transport it. Since it isn't a chemical that is
commonly transported (In that Concentration) there aren't really many off
the shelf solutions for shipping it. So shipping tends to cost about as
much as the peroxide if you are buying a large amount, probably more than
the peroxide if it's a small amount. You could do it yourself of course so
long as you have a hazmat shipping endorsement for whatever method of
transportation you are using.
You could always buy your own 150 lb/day plant from XL-space for $29,600 it
looks like. Though I think you might also have to get permits or other
regulatory things to operate the plant.
Also I cant really think of anyone other than the British, that have done a
Kero/HTP rocket of that size.

Never heard of anybody buying from Michael. He has a big sparger mini
plant in the desert but I wonder if XL-Space is a reliable manufacturer.
Bengtsson 's HTP plant in Sweden OTOH, supplying jetpack enthusiasts in
Europe for many years never recovered after the 2010 fire.
Lastly, I know of no amateur team ever succeeding in launching a British
style kerosine/HTP bipropellant rocket. I said rocket and in the West.
Takes so many years and so much money to build all gave up. Correct me if
I'm wrong.

Just curious. I remember former Armadillo gave up on 80-90 % peroxide
as a propellant because they reported that unexpectedly, they found no
more supplier. As considerable batches were required for their tests
and launches, they had wisely decided to avoid the hassle to distill
it themselves. Realizing such a mini plant of their own for it takes
years to design from scratch and build.
Big companies "responsible care" policy prohibits selling HTP to
rocket amateurs. So where do you buy or intend to buy your HTP at
Monroe?getting a good clean run.

One thing your going to have to be prepared for, at least with using
silver as the catalyst, in my experience no two runs are exactly the
same. There is a little bit of an art in getting a clean run and with
silver, temperature, RH and even barometric pressure can play a role in
