Learn the complete code structure, hierarchy rules, and attribute requirements of the GS1 Global Product Classification taxonomy standard.
GS1 Global Product Classification (GS1 GPC) is the product classification standard developed by GS1, the international organization behind barcodes, GTINs, and the Global Data Synchronisation Network (GDSN). GS1 GPC provides a standardized language for categorizing products traded through the retail supply chain, from food and beverages to healthcare, beauty, and consumer electronics. With approximately 40,000 categories organized into four hierarchical levels, it is the most widely used classification standard for consumer goods data exchange between retailers and manufacturers worldwide.
The taxonomy follows a strict four-level hierarchy: Segment (broadest grouping, e.g., Food/Beverage/Tobacco), Family (category group, e.g., Beverages), Class (product type, e.g., Coffee), and Brick (most specific level, e.g., Coffee - Instant). Each Brick can have optional Brick Attributes that capture additional characteristics like flavor, packaging type, or organic certification. This Segment-Family-Class-Brick structure with Brick Attributes provides a balance between a manageable hierarchy and the detailed product differentiation needed for retail data exchange.
GS1 GPC is a mandatory component of the GDSN data synchronization process. Any manufacturer or retailer exchanging product data through GDSN must classify their products using GS1 GPC codes. Beyond GDSN, the standard is used by major retailers for product onboarding, category management, and shelf planning. Regulatory agencies in food safety, healthcare, and consumer protection also reference GS1 GPC for product identification and recall management. For e-commerce businesses, GS1 GPC provides a well-maintained, retail-focused taxonomy that maps cleanly to other standards like Google Product Category and marketplace-specific category systems.

Key rules and principles that define how this taxonomy organizes products
Every product must be classified to the most specific Brick level in the GS1 GPC hierarchy. The Brick level represents the most granular product type, such as "Coffee - Instant" or "Shampoo - Dandruff." After assigning the Brick code, apply relevant Brick Attributes to further differentiate products within the same Brick. Brick Attributes capture characteristics like packaging type, flavor, target gender, and organic certification that are essential for retail data exchange.
The Segment level in GS1 GPC groups products by their primary industry or function. Products must be assigned to the Segment that reflects their core purpose, not a secondary use case or marketing positioning. A vitamin gummy that is marketed as a candy-like treat still belongs in the Healthcare segment, not Food/Beverage. A medicated shampoo designed for scalp conditions belongs in Healthcare, not Beauty/Personal Care.
GS1 GPC is designed exclusively for physical, tradeable products that move through the retail supply chain. Services, digital downloads, subscriptions, gift cards, and warranty plans should not be classified using GS1 GPC codes. If your catalog includes a mix of physical products and services, use GS1 GPC for products and a separate classification system (such as UNSPSC) for services.
Brick Attributes use controlled vocabularies defined by GS1. Always use the exact GS1-defined attribute values rather than free-text alternatives. Consistent attribute values enable meaningful data exchange with trading partners and allow retailers to accurately compare products from different suppliers. Mismatched attribute values cause data quality issues in GDSN and can result in product listing rejections.
Mandatory and recommended attributes for key categories in this standard
Industries and scenarios where this taxonomy standard is most commonly applied
GS1 GPC is the mandatory classification standard for the Global Data Synchronisation Network (GDSN). Manufacturers and retailers exchanging product master data through GDSN must classify every product with a GS1 GPC Brick code. This ensures consistent product identification across the entire supply chain, from manufacturer to distributor to retailer shelf.
When registering a new GTIN (barcode) with a GS1 Member Organisation, companies are required to assign a GS1 GPC classification to the product. This classification becomes part of the product's permanent identification record and is used by downstream systems to validate product data quality and apply category-specific business rules.
Retailers use GS1 GPC to organize products into logical category structures for shelf planning, assortment optimization, and category reviews. The standardized classification enables retailers to compare product assortments across suppliers and benchmark category performance against industry standards, regardless of how individual suppliers describe their products.
Food safety authorities, pharmaceutical regulators, and consumer protection agencies reference GS1 GPC classifications in product recall notices and compliance reporting. The standardized classification enables rapid identification of affected product categories and ensures recall notices reach all relevant supply chain participants through GDSN alert messages.
Step-by-step guide to implementing this taxonomy standard in your product catalog
Contact your national GS1 office (e.g., GS1 Netherlands, GS1 UK, GS1 US) to obtain access to the GS1 GPC taxonomy. As a GS1 member, you receive access to the full classification including Brick codes, Brick Attributes, and code definitions. Download the taxonomy in your preferred format and review the current version release notes.
For each product in your catalog, navigate the GS1 GPC hierarchy from Segment down to Brick to find the most specific classification. Use the official GS1 GPC Browser tool to search by keyword or browse the tree structure. Focus on what the product fundamentally is rather than how it is marketed. WISEPIM can automate this classification using AI that understands GS1 GPC structure and naming conventions.
After assigning Brick codes, review the available Brick Attributes for each Brick and populate them with the correct GS1-defined values. Brick Attributes capture critical product characteristics such as whether a food product is organic, what flavor it comes in, or whether a medicine is prescription or over-the-counter. Use only the standardized attribute values from the GS1 codelist to ensure data quality.
