D2FC

Delivery-To-FC (D2FC) measures the quality and accuracy of inbound shipments sent to Amazon’s Fulfillment Centers (FCs). It reflects the portion of units that arrive with issues due to:

• Booking errors (e.g., unregistered shipments, incorrect ASN)
• Transit damages (e.g., broken packaging, mishandling)
• Labeling or documentation problems

📊 Formula:
D2FC = (Units with booking or transit defects) ÷ (Total units received)

Why it matters for sellers and vendors:

• A high D2FC rate can trigger chargebacks
• Repeated defects may affect vendor reliability scores
• Impacts in-stock rates and sell-through if goods are delayed or quarantined

💡 Example: If 500 units out of 10,000 received had booking/transit issues, D2FC = 5%.

In short:
D2FC tracks the percentage of defective units in inbound shipments to Amazon FCs - important for minimizing chargebacks and improving supply chain reliability.
