Over-dimensional cargo is a load bigger than the legal size limits for the vehicle (for example a machine that overhangs the body). Validity is counted from the moment the vehicle details are first entered, not from when Part A was filled.

Based on Rule 138 of the CGST Rules, 2017 and the e-way bill portal's FAQ, checked 2026-11-10. Not legal advice; check the official source. Nothing you type leaves this page.

What it does

An e-way bill lets goods move by road under India’s GST. It is valid for a set number of days that depends on the distance: one day for every 200 km or part of 200 km, and for over-dimensional cargo one day for every 20 km or part. Type the distance and the date the vehicle details (Part B) were first entered, and you see the number of days, the exact moment it expires and the window in which the transporter can extend it.

It also tells you whether a consignment of that value needs a bill at all. To plan the stops on a long run use vehicle routing, and to record the trip’s freight, diesel and driver money use trip sheet.

How to use it

  1. Type the distance from the e-way bill (the portal works it out from the PIN codes, and you can add up to 10% more).
  2. Pick normal or over-dimensional cargo.
  3. Pick the date Part B was first entered.
  4. Type the consignment value and whether the goods cross a state border.

What each setting does

  • Distance: the approximate road distance. Every 200 km, or the part of 200 km left over, adds a day.
  • Cargo: over-dimensional cargo moves slowly, so it gets one day per 20 km.
  • Part B date: the first day ends at midnight of the next day, so the hours left on the day you start are a bonus.
  • Consignment value and movement: over 50,000 rupees needs a bill. Many states set a higher limit for goods that stay inside the state.

Worked example

A 450 km run of normal cargo needs 3 days (200 + 200 + 50). If Part B is entered at 3 pm on 10 November, day 1 ends at midnight at the end of 11 November and the bill is valid until midnight at the end of 13 November. The transporter can extend it from 4 pm on 13 November to 8 am on 14 November. A 45 km move of over-dimensional cargo is also 3 days (20 + 20 + 5).

FAQs

What if the truck breaks down? Extend the bill on the portal within the window, giving the reason and the place, or update the vehicle number if the goods move to another truck.

Does a holiday add a day? No. The days run back to back.
