FBA Shipping and Routing Requirements: What Every Seller Must Follow
Covers Amazon's mandatory shipping, packaging, labeling, and routing rules for all FBA inbound shipments, plus the penalties sellers face for non-compliance including defect fees and shipment blocks.
Overview
Amazon enforces strict shipping and routing requirements for all inventory sent to its fulfillment centers through Fulfillment by Amazon (FBA). These rules apply regardless of whether you ship via small parcel delivery (SPD), less than truckload (LTL), or full truckload (FTL). Failing to comply can result in refused shipments, additional fees, and even blocks on future inbound shipments.
Key Points / What Sellers Need to Know
- All shipping methods are covered — Whether you send a single box via UPS or a full truckload, the same baseline packaging, labeling, and routing standards apply to every FBA shipment.
- Carrier and tracking info are mandatory — Amazon requires valid tracking information for all inbound shipments so inventory can be received and processed efficiently at the fulfillment center.
- Product prep compliance is non-negotiable — Every item must meet FBA product preparation requirements, safety requirements, and product restriction guidelines before shipping.
- Non-compliance triggers real consequences — Violations can lead to refused inventory, disposal or return of stock, blocking of future shipments, and inbound defect fees.
- Special rules exist for certain products — Items like large-screen TVs (2017+ model year) require specific packaging certification before being sent via FBA.
Box and Packaging Standards
Amazon requires that all boxes shipped to fulfillment centers meet specific dimensional and weight criteria. Individual boxes in a small parcel shipment must not exceed 50 pounds unless a single oversized item exceeds that weight on its own. Box dimensions generally must stay within standard limits that allow safe handling on conveyor systems and stacking on pallets. Sellers should use sturdy, six-sided corrugated boxes and avoid damaged, warped, or previously used boxes that may compromise structural integrity. Each box must be sealed securely with appropriate packing tape, and excess packing materials like loose fill or packing peanuts should be avoided since they can interfere with Amazon's automated receiving processes.
