1 Introduction
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 purpose of the GDM Attribute Implementation Guide is to provide clarity and practical business advice regarding the use of the GDM attributes and, in some cases, instruction on managing the interaction of multiple attributes.
Attribute groups in development for Attribute Implementation Guidance are as follows:
Group Complete | Attribute Groups |
| Hierarchy |
| Contact information |
| Identifiers |
| Descriptions (brand, product, marketing) |
| Weights & Dimensions |
| Marketing & Consumer Facing |
| Financial (Pricing, pre-tax, price) |
| Packaging (sustainability, returns, recycle) |
| Compliance & Regulatory |
| Import classifications (country of origin) |
| Nutrition Facts (food) |
| Product Life Cycle (dates) |
| Digital Assets (images) |
| Claims & Certifications |
| Category specific (Alcohol, pet, fish) |
Important: The Global Data Model Attribute Implementation Guide is in continuous development. The Guide will be developed and made available to the community in phases based on attribute groups
2 Trade Item Hierarchy
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.
Important: GTINs depicted in the examples in this section are represented generically (e.g. GTIN A, GTIN B, etc.). The specifics of GTIN management and options are out of scope for the Attribute Implementation Guide.
For more information on the GS1 GTIN Management Standard, please refer to www.gs1.org/gtinrules.

BMS ID | ADB Name | ADB Business Definition | Business Process Notes |
56 | Base Unit Indicator | The indicator that specifies this product does not contain another intended sellable unit. | The lowest level of the hierarchy shall be designated as the base unit. The base unit has no smaller units identified by a GTIN contained within it. In the case of assortments, each hierarchy shall have at least one base unit. |
57 | Consumer Unit Indicator | The indicator that specifies the product can be purchased or, in some trade channels (e.g., food service, healthcare), used by, the consumer. | At least one level of the hierarchy shall be designated as a consumer unit. Consumer units are the levels of the hierarchy designated for sale to the customer. |
58 | Shipping Unit Indicator | The indicator identifying that the information provider considers the trade item as a shipping unit. | It is expected that at least one level of the hierarchy be designated as a shipping unit. Exceptions include services and empty returnable assets. |
60 | Orderable Unit Indicator | The indicator that specifies the product can be ordered. | At least one level of the hierarchy shall be designated as an orderable unit. The orderable unit and the shipping unit do not need to be the same, but often are. |
66 | Packaging Level Code | The code that describes the product's packaging level. | Packaging Level Code indicates whether the unit is an each, case, pack, etc. It does not imply that a unit is a consumer, shipping or orderable unit. |
199 | Number of Different Products | The number of different products, each with a unique GTIN, within this item. | This is the number of unique GTINs at the next lower level of the hierarchy. The attribute does not have to be populated if the product is a base unit. |
200 | Total Count of All Products | The total count of all products within this item. | This is the sum all pieces in the package, regardless of GTIN. |
202 | Count of Each Specific Product | The count of each specific product within this item. | This attribute shows the total quantity of each unique GTIN on the next lower level of the hierarchy, by unique GTIN. Count of Each Specific Product and GTIN of the Contained Product shall be populated together. |
3619 | Count of This Specific Item in a Non-GTIN Logistic Unit | The count of this specific item in the non-GTIN logistic unit. | When a product is associated with a pallet to which no GTIN is assigned, this attribute is populated on the highest hierarchy level to which a GTIN is assigned. |
203 | GTIN (Global Trade Item Number) of the Contained Product | The GTIN that uniquely identifies the next lower level product within the packaging/item hierarchy. | This attribute provides the GTIN referenced in the attribute Count of Each Specific Product. Count of Each Specific Product and GTIN of the Contained Product shall be populated together. |
3614 | Number of Layers per GTIN | The number of complete layers in the logistic unit identified by a GTIN, such as a pallet. | Number of layers may also be known regionally as “HI”. |
3616 | Number of Layers per non-GTIN Pallet | The number of complete layers in the pallet not identified by a GTIN. | When a product is associated with a pallet to which no GTIN is assigned, this attribute is populated on the highest hierarchy level to which a GTIN is assigned. |
3618 | Number of Units per Layer in a GTIN | The number of units in a complete layer in a logistic unit identified by a GTIN, such as a pallet. | Number of units per layer may also be known regionally as “TI”. |
3620 | Number of Units per Layer in a non-GTIN Pallet | The number of units in a complete layer in a pallet not identified by a GTIN. | When a product is associated with a pallet to which no GTIN is assigned, this attribute is populated on the highest hierarchy level to which a GTIN is assigned. |
3908 | Variable Measure Indicator | The indicator that specifies the product content is variable. | A value of “true” indicates that the product has variable content. A value of “false” indicates that the product has fixed content. |
3909 | Loose or Pre-Packed Code | The code which informs the buyer of how the product is packed for the selling of products that vary in weight or quantity. | A value of “Loose” designates that the product is not packaged but could be bagged at point of sale. A value of “Pre-packed” designates that the product is contained in a package. |
3 Contact Information
This section deals with a group of attributes that provide detailed information used to communicate with a contact associated with a product. A contact may represent a range of entities, for example a manufacturer, brand owner, importer, customer or consumer support. Contact information may include a telephone number, email address or web site address and is commonly found on the consumer unit package. In addition, some sellers send information that could appear on business documents, such as invoices and packing slips.
The objective in this section is to understand how contact information is populated among this set of attributes.
3.1 Contact Information on a Product Label (Example)
3.2 Contact Information on an Invoice (Example)
3.3 Contact Information Options
3.4 Contact Information – Business Process Notes
Contact Type Code | Contact | Contact Address | Contact Method Code | Contact Details |
Licensee Registrar | ACME Global | 123 Acme Street, Montreal, QC H3Z 2Y7 |

WEBSITE | Website | The identification of a world wide web address. |
Multiple instances of Contact Address (123), Contact (126) and Contact Type Code (127) may exist. The Contact Type Code describes the overall business usage and the content of the associated attributes can vary with each instance. In addition, multiple sets of Contact Method Code (134) and Contact Details (135) may be associated with each repeated group.
BMS ID | ADB Name | ADB Business Definition | Business Process Notes* |
123 | Contact Address | The contact’s postal or physical address. | This information may typically be found on the product packaging or business documentation. In some areas, this could be required subject to local regulation. |
126 | Contact | The contact, such as a person, company or department. | Could be a Company Name, Brand Name, Business Unit or Department. While an individual name is not likely provided, there are instances where an individual name could be provided for specific purposes, such as accounting, licensing, etc. |
127 | Contact Type Code | The code specifying the type of contact for a product. | This information may typically be found on the product packaging or business documentation. |
134 | Contact Method Code | The code specifying the method of communication to reach the contact. | This information may typically be found on the product packaging or business documentation. |
135 | Contact Details | The detailed information used to communicate with the contact, such as the telephone number, email address or web site address. | This information may typically be found on the product packaging or business documentation. |
*Note: Business Process Notes address the primary use case for on-label contact information, however, there could be other use cases such as specific needs around accounting, licensing and regulation.
