Cost structure / standard tiers
Chassis shortages translate into direct cost through extended per diem and indirect cost through missed appointment windows.
| Impact | Normal Conditions | During Chassis Shortage |
|---|---|---|
| Chassis split fee (separate pickup trip) | N/A | $50-150 |
| Chassis per diem rate | $25-35/day | Unchanged, but accrues over more days |
| Average chassis turn time | 1.5-2 days | 4-6 days |
| Driver wait time for chassis swap | 0.5-1 hour | 2-4 hours |
| Effective drayage cost increase | Baseline | 10-20% above baseline during peaks |
These figures reflect typical conditions observed during West Coast import surges, which tend to intensify from late August through early November ahead of the holiday retail season.
Risk mitigation / operational guidance
Return empty containers and their chassis as a paired unit immediately after unloading rather than staging them separately, since uncoupled chassis sitting at a warehouse directly extend pool turn time. Book drayage with carriers who maintain owned chassis pools rather than relying solely on pooled/gray chassis providers, and schedule pickups for early morning slots when chassis availability is typically highest. Build a 1-day buffer into appointment scheduling during known peak-season pool tightness. Where the trucking provider supports it, use street turns to keep a chassis in active use between an import delivery and an export pickup, avoiding a pool return-and-reissue cycle entirely.
