The shelf life shall be marked on the visible surface of the product's sales package with corresponding guide words.
Specific forms and examples for labeling compliance are as follows:
1. Production date and shelf life. The production date shall be marked with Chinese characters or Arabic numerals in the order of a four-digit year, two-digit month, and two-digit date; XX month(s) or X year(s) is recommended to use since the labeling form of shelf date is not specifically stipulated.

The labeling form of the shelf life after opening is not specifically stipulated. EnterCo recommends using Arabic numerals.
