How do I know if a product I am using has been tested on animals?

[cupcake.]

Is there some sort of code or phrase that states so?
And do all products HAVE to state whether it's been tested on animals or not?

Products that are not tested on animals will say "Not Tested on Animals". Any lawn and garden product or household chemical is tested on animals because federal regulations require it.

If you google "not tested on animals list" you will get a few web sites that show which brands are cruelty free.
