I have never seen or heard of tear tags for anything other than shirts. No one makes them most likely as it doesn't really seem needed. Tags in pants, sweatpants, etc usually are not visible, especially when merchandised in a store. They're usually just folded up on a table or shelf. With shirts, the tags are visible and can be a way to do some simple detail to make your brand stick out. So its possible no one makes them. Good luck.
