Overview

Amazon’s fulfillment network on the West Coast has reached full capacity, creating a bottleneck that is slowing both inbound processing and outbound delivery for many sellers. The congestion is stretching the typical two‑day Prime window, prompting a surge in customer service tickets and raising concerns about inventory availability. Sellers should pay close attention because the delays could affect stock levels, performance metrics, and overall profitability, especially if Amazon rolls out a new low‑price, fast‑shipping tier that mimics the Temu model.

Key Points

• West Coast capacity strain — Fulfillment centers in California, Oregon and Washington are reported to be operating at or beyond their designed limits, causing handling times to increase by several days for both inbound and outbound shipments.
• Extended transit windows — Orders dispatched from these West Coast hubs are now regularly exceeding Amazon’s standard two‑day Prime delivery promise, with some shipments taking up to five days to reach customers.
• Team Wish rumors — Internal leaks suggest Amazon may introduce a “Team Wish” service that bundles inexpensive items with ultra‑fast shipping, a strategy that could pressure sellers who rely on higher‑margin products and Prime speed to win the Buy Box.
• Seller inventory risk — Limited dock space means replenishment pallets are queuing longer before being unloaded, raising the probability of stock‑outs for fast‑moving SKUs that depend on timely restocking.
• Performance metric impact — Late shipments are feeding higher Order Defect Rate (ODR) and Late Shipment Rate (LSR) scores, both of which are critical factors in Amazon’s account health algorithm and can jeopardize Buy Box eligibility.
• Carrier route congestion — Major carriers reporting to Amazon are also experiencing route backlogs on the West Coast, which compounds the outbound delay and further stretches delivery windows for Prime‑eligible orders.

How the Shipping Delay Situation Unfolds

1. Inbound congestion — Dock doors at West Coast fulfillment centers remain occupied for extended periods, so a vendor delivering a pallet of 1,200 seasonal accessories may wait an additional 48 hours before the pallet can be moved into the receiving area.
