Overview

Sellers encounter error 30030 when a date field in a product feed contains an invalid value, causing the feed to be rejected and preventing listings from updating or launching. The issue typically surfaces during bulk uploads or when previously valid dates become outdated. Fixing the error quickly is essential to keep inventory and promotions on schedule.

Key Points

• Past dates cause rejection — A discontinue, launch, or promotion date that lies before the current day triggers error 30030, blocking the entire feed.
• Strict date format required — Amazon only accepts dates in YYYY‑MM‑DD or the full ISO 8601 pattern YYYY‑MM‑DDTHH:MM:SS±hh:mm; any deviation leads to a failure.
• Future dates need a 24‑hour buffer — Scheduling a date less than a day ahead is insufficient; the system expects at least a 24‑hour gap before submission.
• All date‑related attributes are checked — The validation applies not just to discontinue dates but also to promotion start/end, launch, and any custom date‑based fields.
• Impossible calendar values are rejected — Dates such as “2024‑02‑30” or “2023‑13‑01” are flagged even if they follow the correct pattern.
• Mixed formats within one file are disallowed — Combining YYYY‑MM‑DD and full ISO timestamps in the same feed causes the error.

How to Resolve Error 30030

1. Identify the affected SKUs — Open the error report, locate the SKU(s) listed under error 30030, and note every date column referenced (e.g., discontinue_date, promotion_start_date). Example: SKU B07XYZ shows the error for both promotion_start_date and launch_date.
2. Audit each date value — Verify that every date is later than today’s date and that it respects the required format. Replace any past dates with a future date that aligns with your marketing plan. Example: Change (past) to .
