Overview

Error 6021 is a listing error that Amazon sellers may encounter when attempting to add an offer or product data to an item designated as "business-only" on the Amazon marketplace. This error indicates that the seller's account lacks the necessary authorization to sell on products reserved for Amazon Business (B2B) participants. Understanding this error is essential for sellers looking to expand into the business-to-business channel or those who unexpectedly encounter it during routine listing activities.

Key Points / What Sellers Need to Know

• What Error 6021 Means — This error fires when a seller tries to create a listing or add an offer to a product that Amazon has classified as a business-only item, and the seller's account is not enrolled in the Amazon Business program.
• Business-Only Items Are Restricted — Certain ASINs on Amazon are flagged exclusively for Amazon Business buyers. Only sellers who are authorized through the Amazon Business Seller program can list offers on these products.
• Cannot Add Product Data Either — The restriction applies not just to offers but also to uploading product data, meaning sellers cannot modify or contribute catalog information for these items without proper authorization.
• Resolution Requires Program Enrollment — To resolve this error, sellers must enroll in the Amazon Business Seller program, which enables them to list business-only products and access B2B features such as business pricing and quantity discounts.

Understanding Amazon Business and Business-Only Items

Amazon Business is a dedicated B2B marketplace that allows registered business buyers to purchase products with features tailored to organizational procurement, such as multi-user accounts, approval workflows, and tax-exempt purchasing. Some products on Amazon are designated as "business-only," meaning they are available exclusively to verified business buyers and can only be listed by sellers who participate in the Amazon Business Seller program. These items often include industrial supplies, bulk products, and specialized equipment that are primarily relevant to business customers rather than individual consumers. When a standard seller account attempts to create a listing on one of these restricted ASINs, Amazon's system returns Error 6021 to block the action.
