How it works
Step 1: Gather information from the user message — product, platform, current situation, and goals.
Step 2: Ask all follow-up questions at once in multiple-choice format. Allow shorthand answers (e.g., "1b 2c 3a").
Step 3: Use the frameworks and methodologies below for research and analysis.
FNSKU Labeling System
- FNSKU definition: A unique identifier assigned by Amazon to each seller SKU, used for inventory tracking at fulfillment centers.
- Labeling requirements: Must cover the original product barcode. Apply to a flat surface, not on curved or wrinkled areas.
- Specifications: 1"x2" size, 300+ DPI print quality to ensure successful scanning. Sufficient blank space is needed around the barcode.
- Barcode covering: If the product already has a UPC/EAN, the FNSKU can be applied directly over it. If there is no barcode, an FNSKU label must be attached.
Packaging Compliance Framework
Amazon packaging requirements are based on two core principles: product protection (preventing damage during shipping) and worker safety.
- General requirements: All items must have a scannable outer packaging barcode.
- Bare products (e.g., hardware): Must use a transparent poly bag with a suffocation warning label and barcode.
- Fragile items: Require bubble wrap or foam packaging, clearly marked "Fragile."
- Sharp-edged products: Protective caps must be added.
- Liquid products: Require leak-proof sealed packaging.
- Multi-packs: Must use manufacturer tape or specific labels to prevent separation.
- Weight limit: Standard cartons maximum 50 lb/23 kg. Exceeding = extra fees or rejection.
Shipment Plans and Carton Optimization
- Shipment plan: Amazon assigns fulfillment centers based on inventory capacity and demand. The system may split shipments across multiple centers.
- Carton packing optimization: Maximize carton utilization within weight/size limits to reduce per-unit shipping costs.
- Fee structure: Standard-size and oversize items have different rates. Large items require precise calculation.
Prep Fee Avoidance Strategies
- Prep service fees: $0.30-1.50 per unit depending on prep type (labeling, bagging, bubble wrapping).
- Self-prep vs Outsourcing: Compare labor costs, equipment investment, time efficiency, and quality consistency.
- Rejection risk: If prep is too complex or product condition is poor, Amazon may reject the entire shipment or dispose of inventory.
Common Root Cause Analysis of Rejections
- FNSKU unscannable: Poor print quality, damaged label, incorrect placement.
- Packaging damaged/missing: Packaging damaged or missing during handling.
- Oversized/overweight cartons: Exceeds standard limits.
- Missing safety labels: Choking warning, sharp edge warning not attached.
- Multi-pack separation: Not properly sealed, causing items to separate.
- Mismatch: Product does not match the shipment plan declaration (incorrect size classification).
- Missing carton labels: Unable to identify shipment destination.
Data Sources
- Amazon Seller Central FBA prep requirements page for product-specific specifications.
- User-provided: product type, size classification, target market, barcode status.
Limitations
- FBA requirements vary by product type and change frequently — always check the latest guidelines.
- Special categories (hazardous materials, lithium batteries, liquids, food) have additional compliance requirements.
- Prep fees add significant cost for complex prep items.
- Rejection may lead to inventory disposal — significant financial loss.
- Shipping costs vary by carton utilization efficiency.
