commercial item determination

When I need to figure out if something counts as a business expense or personal stuff, I look at commercial item determination. It's basically deciding if an item is used for trade, like office supplies or machinery, versus personal use. This matters for taxes and budgeting, so I check how often it's used and its purpose in my work.
