What is GS1 GPC?
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. This is the standard people mean when they say "GPC" without qualification; Google's separate shopping taxonomy is the Google product taxonomy (google_product_category) and is covered in its own guide in this series.
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.

How GS1 GPC is Structured
The key rules and principles behind how this taxonomy organizes products
- 1
Classify to the Brick level and apply Brick Attributes
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.
Classify instant coffee to Brick 10000263 (Coffee - Instant), then apply Brick Attributes for Decaffeinated (Yes/No) and Organic Claim (Organic/Not Organic)Classify dandruff shampoo to Brick 10000455 (Shampoo - Dandruff), then apply Hair Type attribute (Normal, Oily, Dry) - 2
Use the core product function to determine the correct Segment
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.
Medicated anti-dandruff shampoo with active pharmaceutical ingredient goes under Healthcare (51), not Beauty/Personal Care (53)Protein bars marketed as snacks go under Food/Beverage/Tobacco (50), not Healthcare/Supplements (51) - 3
Do not use GS1 GPC for services, digital products, or non-tradeable items
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.

Apply consistent Brick Attribute values across your catalog
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.
Use the GS1-defined value "ORGANIC" for organic certification, not free-text entries like "Certified Organic" or "100% Organic"Use standardized packaging type values like "BOTTLE", "CAN", "POUCH" from the GS1 attribute codelist

GS1 GPC Use Cases by Industry
Industries and scenarios where this taxonomy standard is most commonly used
Retail and GDSN data synchronization
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.
GTIN registration and product identification
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.
Category management and planogramming
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.
Regulatory compliance and product recalls
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.
Pros and Cons of GS1 GPC
- Industry-standard for retail product data exchange through GDSN, making it essential for any manufacturer or distributor working with major retailers worldwide
- Well-maintained Brick Attribute system that captures product characteristics beyond the hierarchy, enabling detailed product differentiation within categories for data quality and comparison purposes
- Strong governance by GS1 with a structured change request process, ensuring the taxonomy evolves thoughtfully and changes are communicated well in advance to adopters
- Deep coverage of fast-moving consumer goods (FMCG) categories including food, beverages, healthcare, beauty, and household products with retail-specific granularity
- The schema itself is free, but putting it to work in retail generally means GS1 membership for GTINs and a paid GDSN data pool subscription, which adds cost particularly for small and medium-sized businesses
- The four-level hierarchy (Segment, Family, Class, Brick) is fixed and cannot be extended by individual organizations, which can be limiting for niche product categories that need additional depth
- Primarily focused on physical consumer goods traded through retail channels; limited coverage of B2B industrial products, services, and digital goods compared to broader standards like UNSPSC
How to Implement GS1 GPC
A step-by-step guide to adding this taxonomy standard to your product catalog
01
Register with your local GS1 Member Organisation
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.
02
Classify your products to Brick level
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.
03
Apply Brick Attributes to each product
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.
04
Publish classified data to GDSN and trading partners
Export your GS1 GPC-classified product data and upload it to your GDSN data pool (e.g., 1WorldSync, Salsify, Syndigo) using the pool's own publishing tools for synchronization with retail trading partners. Validate that all mandatory fields including GPC Brick code, Brick Attributes, GTIN, and product descriptions meet the target data pool's quality requirements. Resolve any validation errors before publishing.
05
Maintain classifications as products and taxonomy evolve
Review each GS1 GPC publication: GS1 publishes the schema twice a year. New Bricks and Brick Attributes are added regularly to cover emerging product categories. When launching new products, assign GS1 GPC classifications during the product setup process rather than retroactively. Conduct periodic audits of existing classifications to ensure accuracy, particularly after major taxonomy updates.
