Overview

Amazon flags listings with error 98888 when hazardous‑material details are missing or incomplete. The error appears for products that contain chemicals, batteries, flammable liquids, aerosols, or any other regulated substance. Sellers must correct the missing dangerous‑goods attributes quickly to avoid listing suspension and revenue loss.

Key Points

• Root cause — The system detects a potential dangerous‑goods item but finds no UN number, hazard class, shipping name, or packing group on the record.
• Typical offenders — Lithium‑ion batteries, aerosol cans, cleaning agents, cosmetics with regulated chemicals, and any item that mentions “flammable,” “toxic,” or “hazardous” in its description.
• Mandatory fields — Amazon requires a UN identification number, the correct hazard class, the official shipping name, and, when applicable, a packing group designation.
• Documentation requirement — A current Safety Data Sheet (SDS) or Material Safety Data Sheet (MSDS) must be uploaded and linked to the exact ASIN.
• Listing consequence — Until the error is cleared, the ASIN is either suppressed from search results or blocked from purchase, directly cutting sales.

How to Resolve Error 98888

1. Locate the dangerous‑goods section — Open the affected ASIN in Seller Central, click Edit and scroll to the “Dangerous Goods” tab. For a lithium‑battery power bank, you will see empty fields for UN 3480, Class 9, and Packing Group II.
2. Enter complete classification data — Fill in every required attribute:
   • UN number – e.g., UN 3480 for lithium‑ion batteries.
   • Hazard class – e.g., Class 9 (Miscellaneous dangerous goods).
   • Proper shipping name – e.g., “Lithium‑ion batteries, packed in accordance with Section II of the IMDG Code.”
   • Packing group – e.g., II for medium danger.
     Missing any of these values will keep the error active.
