LOT code

Label literacy

LOT, BATCH, EXP and PAO markings answer different questions. Cosmetic LOT focuses on the encoded production batch, then applies brand-specific rules to recover the manufacturing date when the rule is known.

LOTA short production-batch identifier printed, stamped, embossed, or ink-jetted on the product or box.
EXPA visible expiry or best-before marking when the manufacturer prints one directly on the label.
PAOThe open-jar period-after-opening symbol, such as 12M or 24M. It is not the same as the manufacturing date.
