There is no technical threshold for tape cutting, just buy a cutting machine. Generally, tape factories will have their own cutting workshops.

Some people who simply cut tapes buy semi-finished tapes from tape factories, then cut them and sell them under their own trademarks. Generally, this kind should have its own sales channels, and it is ok not to worry about not selling it. But if you don't have your own stable sales channels, it will be difficult to make money.
