Overview

Amazon will broaden the list of required product attributes for sellers, starting on August 16 2024 with 25 mandatory fields for 52 product categories. The rollout will culminate in September 2024, when 274 attributes will be enforced across roughly 200 product types. Sellers who do not update their listings to include the new data risk having their offers hidden, losing Buy Box eligibility, or facing account‑health warnings.

Key Points

• Kick‑off date — On August 16, sellers must supply 25 defined attributes for 52 categories, covering basics such as dimensions, material, and country of origin.
• Full scope — By September, the mandate expands to 274 attributes for 200 product types, adding specifics like battery capacity, care instructions, and regulatory certifications.
• Buy Box impact — Listings missing any of the newly required fields after the September deadline will be excluded from the Buy Box and may disappear from search results.
• Tooling changes — Bulk‑upload spreadsheets, flat‑file templates, and API feeds will need extra columns to accommodate the added attributes, affecting sellers who rely on automation.
• Guidance available — Amazon has released updated attribute dictionaries, sample CSV files, and a dedicated help‑center article to assist sellers in the transition.
• Compliance risk — Non‑compliance can trigger health‑metric alerts, higher return rates due to incomplete product information, and possible suspension of the affected ASINs.

How the Mandatory Attribute Expansion Works

1. Publish revised attribute matrix — Amazon releases a detailed matrix that lists every required field for each impacted product type.

   • Example: For “Wireless earbuds,” the matrix now demands entries for “Battery Life (hours),” “Bluetooth Version,” and “Noise‑Cancellation Technology.”

2. Gather required data — Sellers must obtain the new details from manufacturers, invoices, testing labs, or certification bodies.
