This might not be what you’re thinking but maybe if you are saying you need to import it somewhere else you can copy and paste. (This is probably not what you’re thinking.)
savardo is right, import statements are only allowed in module scripts. All you have to do is specify the script type as module exactly as savardo demonstrated and your script (as well as any others you import) is treated as a module. One thing to note is that modules are automatically always in strict mode and also that scope within a module is actually (kindof) local.
