Amazon Chargeback Code PREP: Prep requirement chargeback
Extracted from source — pending expert reviewLast verified: 2026-07-09
What this deduction means
Amazon's Prep chargeback applies when products that require special preparation — such as polybagging, bubble-wrap, or barcode labeling — arrive without the required prep, so Amazon performs it and charges the vendor.
Typical penalty: A per-unit prep fee depending on the prep type
Common causes
- Units needing polybag, bubble-wrap, or a label shipped without prep
- Barcode not applied or not scannable
- Fragile or liquid items not prepped to Amazon's requirements
How to prevent Amazon code PREP
- Apply required prep (polybag, labeling, protection) before shipping
- Confirm each ASIN's prep requirements in Vendor Central
- Ensure barcodes are present and scannable
