Not kosher for Passover matzah

What’s the Halacha regarding matzah marked “not for Passover “
I don’t understand why they don’t indicate more clearly that they are not kosher for Passover, same thing with matzah meals , etc… they look identical

Should not be eaten on pesach. It’s chametz.

Why brands don’t differentiate the design more is something you’ll need to ask the companies themselves. It’s a good question.

Just to clarify, I have not kosher for passover matza meal. This is considered Chametz that I have to sell or dispose? Or can it be kept over Yom Tov.

It’s considered Chametz. Sell or dispose.
