Overview

On May 31 2023 Amazon announced that the ListPrice attribute—its suggested retail price—would become mandatory for a large set of product types. The first enforcement date was November 13 2023, when the rule expanded from 1,000 to 1,773 product types, meaning any new or existing listing in those categories must now include a ListPrice or face errors and reduced visibility.

Key Points

• Initial scope — The rule first covered 1,000 product types when it took effect on November 13 2023.
• Expanded scope — On the same day Amazon added 773 more product types, bringing the total to 1,773 mandatory ListPrice categories.
• Definition — ListPrice is the manufacturer‑suggested retail price (MSRP) that appears on the detail page as “List price.”
• Automatic enforcement — Listings missing the attribute trigger error messages in Seller Central and can be removed from the Buy Box.
• Pricing algorithms — Amazon feeds the ListPrice into its price‑match and discount calculations, which generate the “Save X%” badge shown to shoppers.
• Compliance deadline — Existing listings without ListPrice had to be updated by November 13 2023; any listing created after that date must include the field from the outset.

How the ListPrice Requirement Works

1. Add the attribute — Sellers insert the ListPrice field in a flat file feed or via the product edit UI. Example: A vendor listing a stainless‑steel kitchen knife adds “ListPrice = 49.99 USD” to the CSV row.
2. System validation — Amazon checks the submitted value against the mandatory product‑type list, confirming it is a positive number and matches the required currency format. Example: A toy classified under “Kids Outdoor Play” without a ListPrice returns an “Attribute missing” error in the upload report.
3. Detail‑page display — Once the feed passes validation, the ListPrice appears next to the current sale price, enabling Amazon to compute discount percentages automatically.
