Error 90011 — Quantity exceeds maximum allowed

The quantity submitted (typically over 10,000) exceeds Amazon's per-SKU per-warehouse cap. Amazon caps inventory submissions to prevent demand modeling errors.

Amazon's max quantity per SKU per fulfillment center is generally 10,000 — higher caps require special approval. Submitting beyond this triggers 90011.

1. Cap each SKU's quantity at 10,000 in your feed.
2. If you need higher caps for high-volume SKUs, contact Seller Support.
3. For FBA, send inventory in shipments — Amazon receives, doesn't pre-declare.

• Bulk feed with 50,000+ values — split into multiple shipments
• Negative quantities — invalid, leave SKU out instead
