The term "MFG date" stands for manufacturing date. It is the date when a product was produced or manufactured. The MFG date is often abbreviated as "MFG" on product labels. The MFG date is different from the expiration date, which indicates the date until which a product is safe to use. The MFG date is important because it helps ensure that the label claim levels of ingredients are met prior to being released for sale. The MFG date is also useful for tracking products and identifying potential quality issues.
