Amazon FBA can be incredibly profitable, but only if you master the preparation requirements. Poor FBA prep leads to rejected shipments, additional fees, and frustrated customers. Here are the essential best practices that separate successful FBA sellers from the rest.
1. Perfect Your Product Labeling
Proper labeling is non-negotiable in FBA prep. Amazon's requirements are strict, and violations can result in your entire shipment being rejected.
Critical: Every unit must have an FNSKU label unless it's stickerless, commingled eligible. Never use manufacturer barcodes for FBA shipments.
Label Requirements Checklist:
- Use thermal transfer printers for durability
- Ensure labels are scannable and not wrinkled
- Place labels on flat surfaces, avoid curves
- Never place labels over existing barcodes
- Use white background with black text/bars only
2. Master Case-Packed vs Individual Items
Understanding when to send case-packed items versus individual units can significantly impact your prep efficiency and Amazon's receiving speed.
Case-Packed Guidelines:
- Use for: Identical products in quantities of 6+ units
- Benefits: Faster receiving, reduced prep work
- Requirements: All units identical, proper case labeling
- Avoid for: Mixed products, expiration dates, prep requirements
3. Packaging That Protects and Complies
Amazon's packaging requirements exist to protect your products during the fulfillment process. Proper packaging reduces damage and returns.
Packaging Best Practices:
- Use poly bags for items over 5" on any side
- Include suffocation warnings on all poly bags
- Bubble wrap fragile items individually
- Use original manufacturer packaging when possible
- Avoid overpacking—it increases costs and disposal fees
4. Optimize Your Shipment Planning
Strategic shipment planning can save significant time and money in your FBA operations.
Small Parcel Delivery
Best for: Test quantities, urgent restocks, lightweight items under 50 lbs
LTL Freight
Best for: Large volumes, heavy items, palletized shipments over 150 lbs
5. Handle Expiration Dates Properly
Products with expiration dates require special attention in FBA prep:
- Must have 50+ days remaining when received by Amazon
- Group by expiration date—never mix dates in shipments
- Use YYYY-MM-DD format for date labels
- Apply expiration date labels to each individual unit
6. Streamline Your Prep Workflow
Efficiency in prep translates directly to profitability. Develop standardized workflows:
Recommended Prep Sequence:
- Receive and inspect inventory
- Apply FNSKU labels to each unit
- Package items according to requirements
- Create shipment in Seller Central
- Print and apply shipment labels
- Arrange pickup or delivery
7. Avoid Common Prep Mistakes
These mistakes can result in rejected shipments and additional fees:
- Mixed SKUs in boxes: Each box should contain only one SKU
- Incorrect shipment contents: What you ship must match your plan
- Missing required prep: Polybag, labeling, or packaging requirements
- Poor box selection: Oversized boxes increase costs and damage risk
8. Leverage Technology
The right tools can dramatically improve your FBA prep efficiency:
- Label printers: Thermal transfer for durability
- Inventory management: Track prep requirements by SKU
- Batch processing: Group similar prep requirements
- Quality control: Checklists and inspection processes
9. Monitor Performance Metrics
Track these KPIs to optimize your FBA prep:
Operational Metrics
- • Prep time per unit
- • Shipping cost per unit
- • Receiving time at Amazon
- • Problem rate percentage
Quality Metrics
- • Shipment acceptance rate
- • Units received vs sent
- • Damage/defect rates
- • Customer complaint rates
10. Consider Professional Prep Services
As your business scales, professional FBA prep services can offer significant advantages:
When to Consider Professional Prep: If you're spending more than 10 hours per week on prep, or if prep mistakes are costing you more than outsourcing would.
