Not really sure what the answer is. I guess depending on the corporate law in each nation, and depending on whether the company was privately owned or publicly traded on a stock exchange, the exact tag name would change. In the UK, you see the letter LLC a lot (limited liability company?).
Again, not really sure what the different corporate tags mean. Someone who is more of an expert in corporate law might be able to chime in here. I always find it fascinating looking at the various corporate names you will see on the rating plates of Eureka vacuums throughout its history: The Eureka Company, Eureka-Williams Company, Eureka-Williams Corporation - Division of National Union Electric Company, Eureka Company - Division of White Consolidated Industries, Eureka Division of North American Electrolux, Electrolux Floor Care of North America, Eureka Division of Onward Manufacturing in Canada, Euroclean Canada, etc.
It would be fun to start a thread of pictures of ratings plates from vacuum cleaners. We’d get to see the wide variety of corporate names branded underneath vacuum cleaners.
