The OU Kosher Division has released a list of items which do not require Kosher for Passover certification.
This list, which has been reviewed by the OU Poskim, is part of a larger goal to help people observe Passover to the highest standards of Halacha and Kosher while maintaining their simchas yom tov.
The list, which is not meant to be exhaustive, is designed to alleviate some of the misconceptions about what can and cannot be used on Passover without special supervision.
