How to Categorize Products for Walmart Marketplace

Understanding Walmart Product Categorization

Walmart Marketplace has grown to become the second-largest e-commerce platform in the United States, with over 100,000 sellers and millions of products. As a Walmart seller, proper product categorization is critical for success. Walmart's taxonomy determines product placement in search results, browse navigation, and even affects whether your listing is approved at all.

Walmart enforces strict category requirements—incorrect categorization can lead to listing rejections, suppressed products, or even account suspension. Unlike some marketplaces that allow broad category placement, Walmart requires sellers to place products in specific "leaf" categories that precisely match the product type. This precision helps Walmart maintain its curated marketplace experience.

Our AI-powered categorization tool is specifically trained on Walmart's product taxonomy. It analyzes your product descriptions and attributes to identify the exact Walmart category, complete with the Category Path and Category ID needed for API integration. The system understands Walmart's unique categorization rules, including restricted categories, gated products, and compliance requirements.

Walmart Product Taxonomy Structure

Walmart organizes products into a hierarchical taxonomy with Departments at the top level, followed by Categories, Subcategories, and Product Types. Each product must be assigned to the most specific applicable Product Type (leaf category) for the listing to be approved.

The Walmart taxonomy is distinct from Amazon, Google, or other marketplace taxonomies. A product that fits "Electronics > Computers" on Amazon might need to go into "Electronics > Computers > Laptops > Gaming Laptops" on Walmart. Our AI understands these differences and maps products to the correct Walmart-specific categories.
