Buying standard ICFs from a lesser known regional manufacturer doesn’t pose any significant risk.
Anyway, there is a dividing line that you should not forget – the one separating standard ICF manufacturers, with EPS-made products, from those offering non-EPS products (involving proprietary and alternative insulation materials).

Manufacturers offering ICFs for floors and ceiling construction.
A few manufacturers are offering ICF forms for floors and ceilings. These products are reinforced with steel beams, and are great for site-cast or precast concrete floors, roofs and decks.
BuildBlock and Nudura have one-side-only insulation products - a feature that may be advantageous for some high thermal mass strategies.
Finding local ICF dealers
Many ICF manufacturers have “find a dealer” page on their site.
The EPS Industry Alliance, the North American ICF industry association, has also a find a member tool.
