Are those constants hardcoded item options? If yes on which items are those applicable?

[Goldenheaven]

These are part of the item id mask of ep8+, for example before premium pc theres grade/item level.

ItemID:
Part 1 of ID: 12 bits
Level: 5 bits
Premium PC: 1 bit
Bind item in equip: 1 bit
Nothing: 3 bits
Special Inventory item: 1 bit
Item id part 2 (for items with id bigger than 33554432 on cabal_msg): 1 bit

Basically these are (1 << n) and its a mask like character style.

Max ItemID of Item without options in bits:
0000 0000 0010 0000
0000 1111 1111 1111
