Overview

Amazon announced on May 15, 2024 that the ListPrice attribute will become mandatory for any listing submitted through the Listings API or the JSON Listings Feed, while the MSRPWithTax field will be required for XSD/XML feed uploads of certain product categories. The original enforcement date was set for May 27, 2024, but Amazon has now delayed the rollout, giving sellers an additional window—roughly two weeks—to modify their data pipelines before the new rules become active. Sellers who rely on automated feeds or API integrations need to understand the updated timeline and adjust their systems to avoid listing rejections.

Key Points

• Original deadline — ListPrice and MSRPWithTax were slated to be required beginning May 27, 2024.
• Postponement announced — Amazon has pushed back the enforcement, though a specific new compliance date has not yet been disclosed.
• Affected submission methods — The requirement applies to Listings API calls, JSON Listings Feed files, and legacy XSD/XML feed uploads.
• Targeted product types — Only categories that traditionally use manufacturer‑suggested pricing, such as appliances, electronics, and certain toys, must include the new attributes.
• Seller preparation window — The delay adds roughly a two‑week period for developers and catalog teams to update integration code, feed generation scripts, and validation processes.

How the ListPrice & MSRPWithTax Requirements Work

1. Identify qualifying product types — Determine whether a SKU belongs to a category that now mandates a price‑suggestion attribute.

   • Example: A seller adding a new stainless‑steel blender must first verify that the “Kitchen Appliances” category is flagged for ListPrice enforcement before proceeding.

2. Add ListPrice to Listings API payloads — Include a listPrice object in every POST or PUT request that creates or updates a listing.
