Transit time is usually stated as a range because several things beyond distance decide where in that range a load arrives.
Consolidation
A part load waits until its truck is full. On a busy corridor that can be quick; on a quieter one it adds days. A full container skips the wait entirely.
State borders
A long corridor crosses several states, each with its own checks. Documentation that travels with the truck keeps these short.
Weather and season
- Monsoon water can close stretches at short notice
- Summer heat through central India slows daytime driving
- Festival periods crowd the highways
The arrival city
Some cities limit when large vehicles may enter. A load bound for Delhi is timed to its commercial vehicle hours, while one bound for Noida can take the Yamuna Expressway and avoid the city altogether.
How we state it
The window in your bond already accounts for these. If delivery runs past it, the delay credit of ₹1,000 per day applies after the grace period.
