GS1 Standards

GS1 Hong Kong has been dedicated to enhancing Hong Kong enterprises' competitiveness through the provision of global supply chain standards, technology and best practices underpinned by GS1 philosophy.  As GS1's local chapter, GS1 Hong Kong is the only organization who is authorized to issue and administer GS1 System of Standards in Hong Kong. 

The GS1 System of Standards is a set of global standards that enable the unique identification of all trade items, processes, services, assets, companies and locations at any point in the supply chain.  As a global language for efficient business, GS1 Standards enables companies of all size to identify, capture, and share information throughout the global value chain. No matter where a business is based or what language you use, trading partners can always understand one another using GS1 standards. 

GS1 Standards - Identify, Capture, Share

The GS1 System of Standards is built upon two elements: GS1 Automatic Identification Standards and GS1 Communication Standards.

GS1 Automatic Identification Standards

GS1 Automatic Identification Standards are themselves composed of several elements: GS1 Identification Keys and Application Identifiers, GS1 Data Carriers and the EPC identifier.

GS1 Identification Keys are specially designed to work with the GS1 Data Carriers: GS1 BarCodes or EPC/RFID tags. The EPC, which incorporates GS1 identification Keys as well as Keys from other systems, is the foundation for encoding an EPC/RFID tag.

GS1 Communication Standards

GS1 Communication Standards deal with transactional data, which is data that acknowledges the completion of a business transaction such as one supported by GS1 eCom standards; they deal with visibility data, which is data that logs the occurrence of a physical event (i.e. items loaded onto ship, arrived in port and inspected at customs) in EPCIS; and they enable master data sharing between trading partners in the supply chain using the Global Data Synchronization Network (GDSN).

The GS1 standards are applicable in an array of industries from manufacturing, retail through to healthcare and food services helping businesses improve their supply chain efficiency and visibility.
