Amazon FBA can significantly boost sales—but only if your inventory meets Amazon’s strict preparation and compliance requirements. Even small mistakes in FBA prep can lead to rejected shipments, delayed listings, extra fees, or account health issues. Understanding these common errors can help sellers avoid costly setbacks.
1. Incorrect or Missing FNSKU Labels
One of the most frequent Amazon prep mistakes is improper labeling. Missing, incorrect, or poorly placed FNSKU labels can cause Amazon to misidentify inventory, leading to delays or penalties. Overlapping barcodes or uncovered manufacturer labels are also common issues.
How to avoid it:
Ensure every unit has a clear, scannable FNSKU label placed correctly and that all other barcodes are removed or covered.
2. Non-Compliant Packaging
Amazon has specific packaging rules depending on product type. Sellers often make mistakes such as:
- Using incorrect poly bags
- Missing suffocation warning labels
- Improper sealing or loose packaging
- Exceeding size or weight limits
These errors can result in shipment refusal at Amazon Fulfillment Centers.
3. Poor Protection for Fragile Items
Fragile products require adequate protection. Insufficient bubble wrap, missing box protection, or weak sealing can lead to product damage during transit or storage.
Tip: Follow Amazon’s drop-test requirements and ensure all fragile items are securely packed.
4. Incorrect Bundling or Kitting
Many sellers fail to label bundles correctly. If items are not marked as “Sold as Set,” Amazon may separate them, causing inventory discrepancies and listing issues.
5. Inaccurate Carton Labeling
Carton labels must match the shipment plan exactly. Incorrect box content details, wrong labels, or missing shipment IDs can delay inventory check-in or lead to misrouted shipments.
6. Overlooking Expiration Dates & Product Restrictions
For consumables, supplements, or cosmetics, missing expiration date labels or non-compliant formats can result in rejected inventory. Additionally, some sellers send restricted or gated products without proper approvals.
7. Ignoring Amazon’s Frequent Policy Updates
Amazon regularly updates its FBA prep requirements. Sellers who rely on outdated guidelines often face compliance issues, unexpected fees, or rejected shipments.
8. Attempting In-House Prep Without Expertise
While in-house prep may seem cost-effective, it often leads to errors due to lack of experience, tools, and updated compliance knowledge—especially for high-volume sellers.
