I know because it is not a liquid I am required by law to list it as "# oz", but do I need to state "net weight oz"? I list net wt. Is it recommended that I include grams or mililiters? I use oz or grams. Depends on what it is. I notice some companies will include ounces/grams as well as ounces/milliliters. I'm cornfused. Oh yeah, and does it need to be on the very front of the label?? Yes
