The more important is a return shipping from your retipper :)
In my county you can’t insure a cartridge to whatever value you want, you must prove the real cost with real/valid documents. For example you can’t ship a $500 cartridge (or a piece of junk) with $5k insurance pretending you will get $5k if it’s lost :)
For international shipping (not your case) insurance must be equal to declared value, so the import tax will be charged by custom, in Europe import tax is extremely high (can be over 20%) and it’s better to declare as low as possible without any insurance.
