What's Happening
Amazon's Ships in Product Packaging (SIPP) program is gaining urgency as an alternative to discontinued FBA Prep services. With FBA Prep ending on January 1, 2026, sellers can now save $0.04 to $1.32 per unit by shipping products in their original packaging instead of requiring Amazon to add an additional shipping box. Our team flags updates like this for cohort review because they bend the metrics our customers stare at every day. Our team flags updates like this for cohort review because they bend the metrics our customers stare at every day.
SIPP-certified products ship directly in their retail packaging with a shipping label applied to the product box. This eliminates the need for Amazon to repackage items, reducing fulfillment costs and environmental waste. Currently, about 12% of Amazon shipments use SIPP. Amazon expects significant growth as sellers seek cost savings and sustainability improvements.
SIPP Savings by Size Tier
| Size Tier | Dimensions | SIPP Discount |
|---|---|---|
| Small Standard | Up to 15" × 12" × 0.75" | $0.04/unit |
| Large Standard | Up to 18" × 14" × 8" | $0.13/unit |
| Large Bulky | Up to 59" (longest side) | $1.06/unit |
| Extra-Large (0-50 lb) | Over 59" or 50+ lb | $1.32/unit |
Example Savings
A seller shipping 10,000 Large Standard units per month saves $1,300/month ($15,600/year) through SIPP. For Large Bulky items at the same volume, savings jump to $10,600/month ($127,200/year).
Eligibility Requirements
Package Must Be
- → Minimum 6" × 4" × 0.375" for label compliance
- → Durable enough to survive shipping without outer box
- → Able to protect product from damage and exposure
- → Non-transparent (contents not visible)
Not Eligible
- → Fragile items without ISTA-6 certification
- → Products in bags or pouches
- → Glass containers
- → Temperature-sensitive products
ISTA-6 Certification Process
For fragile items, Amazon requires ISTA-6 (Amazon.com-SIOC) certification to prove your packaging can survive the fulfillment network without additional protection. This testing simulates the stresses products encounter during shipping.
| Certification Step | Details | Cost |
|---|---|---|
| Find ISTA Lab | Locate an ISTA-certified testing laboratory | , |
| Submit Samples | Send 10-20 packaged units for testing | Shipping costs |
| Testing | Drop tests, vibration, compression | $300-$2,000 |
| Certification | Receive pass/fail report and certificate | Included |
Pro Tip
Start with your highest-volume SKUs. If certification costs $1,500 and you save $0.50/unit, you break even at 3,000 units. High-volume products recoup certification costs quickly.
