Tender Lead Times Hit 6-Year High: What Shippers Need to Know

Tender lead times in the U.S. trucking market have drifted upward for six consecutive years, with the current SONAR Tender Lead Time Index (STLT) sitting at 3.74 days versus a historical average of 3.37 days. This metric, which measures the gap between when shippers tender a load and their desired pickup date, has become increasingly important as a window into shipper confidence and capacity anxiety. What's notable is that these longer lead times persist even during periods of loose capacity, breaking the traditional pattern where abundant trucks enable just-in-time tendering. The sustained increase reflects multiple converging factors beyond simple capacity constraints.

Improved forecasting tools and supply chain optimization processes enable shippers to plan volumes further in advance. Trade policy volatility, particularly the ongoing threat of tariffs and geopolitical disruptions, has forced shippers to maintain higher inventory buffers, extending their shipping windows. The rise of domestic intermodal as a viable alternative has also shifted shipper behavior, longer lead times provide flexibility to route freight via rail, undercutting trucking demand even when capacity appears available. For supply chain professionals, this trend carries both operational and strategic implications.

While carriers benefit from better equipment positioning and fewer service failures, shippers must recognize that rising lead times represent structural changes in market dynamics rather than temporary anomalies. Understanding the drivers behind these longer windows, whether driven by deliberate buffering or market softening, is critical for optimizing procurement strategies and maintaining competitive positioning in an increasingly complex transportation landscape.
