This document discusses product labelling and its functions. Labelling can range from simple tags to complex graphics and may identify the product, grade it, describe contents and usage instructions, or promote the brand. For many companies, labels are an important part of marketing. Common labels required on various products include the manufacturer, country of origin, materials, and instructions for clothes, and ingredients, nutrition information, and barcodes for foods. While important for information, labelling must be truthful and not mislead customers to avoid legal issues. Regulations for labelling vary by country.
