Overview

Amazon's Bulk Services program allows sellers to link multiple package configurations of the same product — such as individual units, case packs, and pallets — under a unified package hierarchy. This feature streamlines catalog management for sellers who offer products in more than one quantity format, making it easier for business buyers to find and purchase in their preferred configuration.

Key Points / What Sellers Need to Know

• Two or more configurations required — To use package hierarchy, you must offer at least two different package configurations of the same product, such as a single unit and a case pack, or a unit and a pallet.
• Pallet selling is optional — You do not need to offer pallet-level quantities to participate. Any combination of two or more configurations (unit, case pack, or pallet) qualifies.
• Existing ASINs can be linked — If you already sell a product as both individual units and case packs, package hierarchy lets you formally connect those listings so buyers can easily toggle between options.
• Four-step setup process — Amazon provides a straightforward four-step workflow within Seller Central to create and manage your package hierarchy.
• Designed for B2B volume selling — Package hierarchy is especially valuable for sellers active on Amazon Business, where commercial buyers frequently purchase in bulk quantities.

How Package Hierarchy Works

Package hierarchy is a catalog feature within Amazon's Bulk Services that establishes a formal relationship between different quantity configurations of the same product. For example, if you sell a box containing 10 pens as your base unit, and you also offer a case pack of 10 boxes (100 pens total), the package hierarchy links these two listings together. This relationship allows Amazon to display the different purchasing options to buyers in a connected, intuitive way. Buyers browsing one configuration can easily discover and switch to another quantity option without having to search separately, which can increase your overall order volume.

Setting Up Your Package Hierarchy

Before starting the setup process, sellers should first identify all products in their catalog that are currently offered — or could be offered — in multiple package configurations. The three configuration types available are unit (a single sellable item), case pack (multiple units bundled together), and pallet (a large-quantity shipment format). Once you have identified which products qualify, Amazon's four-step creation process within Seller Central guides you through linking these configurations together. Each configuration in the hierarchy needs its own ASIN, so sellers should ensure that all relevant listings are active and properly set up before beginning the linking process.
