FDA's proposed hub-and-spoke registration rule treats geographically separate manufacturing units as one establishment. The registration paperwork is new; proving that blend uniformity, granulation endpoints, and moisture behavior actually match between sites is the older, harder problem.
AIR7359 explains why AMS-AM metal powder feedstock specifications leave certain properties uncontrolled, citing limited applicability and immature standardized inspection methods, and what that gap means for aerospace AM qualification programs.
Talc's expected EU restriction is forcing cosmetic formulators toward mica, kaolin, silica, and starch. None of them reproduce talc's platelet slip, oil absorption, and low dustiness at the same time, and each substitution changes flow and compaction behavior in pressed powder products differently.
Kst quantifies explosion rate-of-pressure-rise under standardized lab conditions. It does not directly describe how an explosion behaves in your vessel, at your turbulence level, or with your ignition scenario. This insight explains what the number means, where the cubic law holds, and when a competent person must go further than the test certificate.
