Overview

Amazon sellers are now facing longer inbound transit times and tighter carrier capacity as the logistics environment evolves. In a recent Serious Sellers Podcast, Bradley Sutton, Helium 10’s Director of Training and Chief Evangelist, explained the drivers behind these shifts and outlined what sellers should expect in the coming months. Understanding the new dynamics is critical for maintaining inventory flow and protecting fulfillment performance.

Key Points

• Carrier capacity crunch — Major carriers are running near‑full loads, adding an extra 3‑5 days to the time it takes for inbound shipments to reach Amazon fulfillment centers.
• Greater reliance on Amazon‑partnered carriers — Amazon is nudging sellers toward its own network of partnered carriers, which offer lower rates but enforce tighter pickup windows.
• Move toward regional fulfillment — Sellers are consolidating stock in fewer, strategically placed warehouses to cut last‑mile costs and avoid cross‑country delays.
• Rising freight costs for LTL and parcel — Spot rates for less‑than‑truck‑load (LTL) freight have climbed 15‑20 % year‑over‑year, prompting many sellers to test rail or intermodal options.
• Extended inventory planning cycles — Forecasting horizons have stretched from roughly 30 days to 45 days, forcing earlier reorder points to keep shelves stocked.
• Technology‑driven visibility — New dashboards and predictive analytics tools are becoming standard, giving sellers early warnings of potential delays.

How the New Shipping Landscape Works

1. Carrier Booking & Slot Allocation — Sellers place freight requests through Amazon’s Transportation Management System (TMS) or a third‑party logistics (3PL) platform. The system assigns a carrier slot based on current capacity, often pushing the pickup date back. Example: A Texas‑based seller books an LTL pickup for June 1, but the carrier confirms a June 4 departure because of limited space.
2. Transit & Consolidation — After loading, shipments travel to regional Amazon hubs where they may be merged with pallets from other sellers before proceeding to the final fulfillment center.
