Hello Gregory! Thank you for sharing your feedback. Dishwasher detergent pacs do not carry expiration dates; the code printed on the packaging is a manufacturer batch/lot code used for quality control and traceability, not an expiration indicator. Dishwasher detergents are classified as non-perishable household cleaning products and are not subject to expiration dating requirements. When stored according to manufacturer guidelines, they remain safe and usable. All items we ship are new, authentic products and are stored in appropriate conditions. If a package arrives with damage or leakage, customers are encouraged to contact Walmart Customer Care for assistance.
