The qualifiers for the Beyblade X World Championship are happening in June! While the official information about allowed parts doesn't state it directly, Zero from BBAN Melbourne has been in touch with Hasbro and learned that you will only be able to use parts released by Hasbro, or identical parts released by Takara Tomy.
Takara Tomy parts must be the same colour as a part released by Hasbro. For example you can use a purple, black, or green Shark Edge, but not a yellow or blue one.
This is true for launchers as well, you can use the black winder launchers and black ripcords, and the red string launcher and blue left string launcher, but not any other colours.
To make it easier for bladers to understand what is allowed I have put together this list. The parts listed here are based on this page on the official site.
Images are from Fabel's Beyblade X Available Colors spreadsheet, really awesome resource. Head there if you need help identifying any of the parts in this list.
Launchers
Launcher grips, battle passes, slip grips, and any other kind of launcher attachments are not allowed.
