Product marking refers to the process of labeling or tagging products to provide essential information about them. This can include details such as the product's name, manufacturer, expiration date, and safety instructions. Marking helps consumers make informed choices and ensures compliance with regulations. In many industries, product marking is crucial for traceability and quality control. For example, in the food industry, products are often marked with barcodes or QR codes that allow for easy tracking throughout the supply chain. This practice enhances transparency and helps in managing recalls if necessary.
