A trade item hierarchy consists of multiple GTINs linked together to represent a product's packaging hierarchy levels. Each level of the hierarchy is assigned a unique GTIN, and represents that specific unit, pack, case, or pallet.

The objective in this section is to understand how to set up trade items with different hierarchies – a simple hierarchy, a complex hierarchy, a hierarchy containing a variety pack and a hierarchy containing a display unit.

The purpose of the Global Data Model (GDM) is to simplify and harmonise the exchange of master data. The GDM will identify and define—in a globally consistent way—the set of foundational attributes needed to manage a product through its life cycle, such as: listing/ordering, moving, storing and selling a product both digitally and physically. The intention of the GDM is to enable an improved Consumer experience and reduce complexity by harmonising foundational data across the industry.

The following table is a summary of all cross references Standards and Best Practices in relation to the Control Points:

A.2.1 ISO 22005-2007

The GS1 GTC Checklist has been benchmarked against ISO 22005-2007, Traceability in the feed and food chain – General principles and basic requirements for system design and implementation. The following table presents the cross reference between the GS1 GTC Checklist and the traceability requirements and clauses of ISO 22005-2007 Standard:

There are several Control Points in the GS1 GTC Checklist that relate to certain traceability requirements of other relevant standards and regulations. This Appendix cross references the Control Points in the GS1 GTC Checklist and the traceability requirements of the following (non-GS1) standards and regulations:

1. ISO 22005-2007

2. ISO 9001-2015

3. ISO 22000-2018
