Improper packaging is one of the top reasons Amazon FBA shipments get rejected, delayed, or assessed additional fees. Every Amazon seller shipping from China must understand Amazon's packaging requirements before sending products to fulfillment centers.
This guide covers everything you need to know about Amazon FBA packaging requirements, from general rules to product-specific guidelines.
Why Packaging Matters for Amazon FBA
Amazon's fulfillment centers process millions of units daily. Your packaging must withstand:
- Long-distance shipping from China to the USA (potentially 30+ days in transit)
- Multiple handling points — port loading, unloading, trucking, FBA warehouse processing
- Automated sorting systems at Amazon facilities
- Customer delivery — Amazon ships your product in its original packaging or an Amazon box
Poor packaging leads to: - FBA shipment rejection (Amazon sends it back at your expense) - Additional prep fees ($0.50–$2.00 per unit) - Customer returns due to damaged products - Negative reviews and lower seller metrics
General Packaging Requirements
Amazon has strict packaging rules that apply to all FBA products:
1. Product Must Be Properly Sealed
- Poly bags: Must be sealed with a suffocation warning (for bags 5" × 5" or larger). Warning text must be in at least 10-point font.
- Shrink wrap: Must be tight and secure with no loose edges.
- Boxes: Must remain closed when dropped from 2 feet. Use strong packing tape — not masking or cellophane tape.
2. No Exposed Barcodes
- Only one scannable barcode should be visible on the product — either the manufacturer's UPC/EAN or your FNSKU label.
- Cover all other barcodes with opaque tape or remove them entirely.
3. No Marketing Materials Inside
- Amazon prohibits marketing materials, coupons, price tags, or promotional inserts inside product packaging.
- This includes competitor marketplace logos (e.g., Walmart, eBay stickers).
4. Expiration Dates Must Be Visible
- Products with expiration dates must have the date printed on the outside of the packaging in 36-point font or larger.
- Expiration date must be in MM-DD-YYYY format.
5. Suffocation Warning for Poly Bags
All poly bags with an opening larger than 5 inches must have a printed suffocation warning:
"WARNING: Keep away from children. This bag is not a toy. To avoid danger of suffocation, keep this bag away from babies and children. Do not use in cribs, beds, carriages, or playpens."

Use Amazon's FBA Prep Service (convenient but most expensive)

Packaging Cost Optimization Tips
- Prep at the factory: Train your Chinese supplier to apply FNSKU labels and use correct packaging — saves $0.50–$2.00 per unit.
- Buy poly bags in bulk: Purchase pre-printed poly bags with suffocation warnings in bulk from Alibaba (cost: $0.02–$0.05 per bag).
- Optimize product dimensions: Even a 1cm reduction in packaging size can move your product to a cheaper FBA size tier, saving $0.50–$2.00 per unit.
- Standardize box sizes: Use standard box sizes to reduce freight volumetric costs and simplify FBA shipment planning.
- Combine prep with freight: Use a freight forwarder that also offers FBA prep (like Skyler Logistics) to avoid shipping to a separate prep center.
