Symbols used on packages and labels

Many types of symbols for package labeling are nationally and internationally standardized. For consumer packaging, symbols exist for product certifications such as the FCC and TUV marks trademarks, proof of purchase, etc. Some requirements and symbols exist to communicate aspects of consumer rights and safety, for example the CE marking or the estimated sign that notes conformance to EU weights and measures accuracy regulations. Examples of environmental and recycling symbols include the recycling symbol, the recycling code  and the “Green Dot”. Food packaging may show food contact material symbols.

Bar codes, Universal Product Codes, and RFID labels are common to allow automated information management in logistics and retailing. Country of Origin Labeling is often used. Some products might use QR codes or similar matrix barcodes. Packaging may have visible registration marks and other printing calibration and troubleshooting cues.

Technologies related to shipping containers are identification codes, bar codes, and electronic data interchange. These three core technologies serve to enable the business functions in the process of shipping containers throughout the distribution channel. Each has an essential function: identification codes either relate product information or serve as keys to other data, bar codes allow for the automated input of identification codes and other data, and EDI moves data between trading partners within the distribution channel.Small parcel carriers often have their own formats. For example, United Parcel Service has a MaxiCode 2-D code for parcel tracking.RFID labels for shipping containers are also increasingly used. A Wal-Mart division, Sam’s Club, has also moved in this direction and is putting pressure on its suppliers to comply.Shipments of hazardous materials or dangerous goods have special information and symbols as required by UN, country, and specific carrier requirements. On transport packages, standardized symbols are also used to communicate handling needs. Some are defined in the ASTM D5445 “Standard Practice for Pictorial Markings for Handling of Goods” and ISO 780 “Pictorial marking for handling of goods”.
