Expiration dating of nacconal 90 f
This information is entirely at the discretion of the manufacturer.Most expiration dates are used as guidelines based on normal and expected handling and exposure to temperature.This is often indicated by a graphic of an open tub, with the number of months written inside (e.g., "12M" means use the product within 12 months of opening).Similarly, some food products say "eat within X days of opening".It is also important to follow storage instructions carefully for these foods (for example, if they specify that the product must be refrigerated).
Further, beyond the expiration date the manufacturer will no longer be monitoring the safety of the seat through testing.
This contrasts with a best before date which is an indication of how long properly stored prepackaged food is expected to retain its "freshness, taste, nutritional value, or any other qualities claimed by the manufacturer." Passing a best before date is not necessarily a reason to discard the food.
"Sell by" and "manufactured on" dates are related concepts that may guide the consumer. For example, in Canada, all children are required to be secured in an infant car seat while in a motor vehicle that is in motion.
These practices reduce the risk of customers unknowingly buying food without looking at the date, only to find out the next day that they cannot use it.
Tampering with the posted date is illegal in many countries.
Arbitrary expiration dates are also commonly applied by companies to product coupons, promotional offers and credit cards.
