You do realize that this name format extends far beyondproduct listings? And you do realize whatever Takara Tomy releases the name they use, in any format, is the official name across all franchises. You disregarding it for only product listing is nonsensical. There's not other naming source. Just because you string the parts names together doesn't mean that that's the true official name.
Takara Tomy makes sure that their name format is used every where! It's used in Japanese Beyblade Burst video games; it's used in the Japanese manga in the character profiles; It's used in the character pages on the official Japanese Beyblade anime site for the character's Bey(s) (Like Hyuga's page). Even the hosts in Takara Tomy product promotion videos announce the Bey's names using this format! This is his background: Takara Tomy made sure to that all franchises utilize this Beyblade name format (katakana and all) in everything from paperback advertising to commercials and product promotions (even the instruction sheets and beycode cards included in product packaging). And they make a clear distinction between the pronunciations of the part's full name and their abbreviation.
