What is the CPSIA?

What information has to be put on the label or alternatively, somewhere on the product and/or its packaging?

the name of the manufacturer or private labeler
the location of production (city, state/province, and country)
the date of production OR a mark, such as a batch number or cohort number, that you can use to look up the date [...]

CPSC’s tracking label guidance gives you some flexibility in determining your “date of production.”
