Every logistics manager has lived this moment: a truck breaks down on the highway, the delivery deadline is looming, and the e-way bill in the driver’s cab suddenly feels like a ticking clock. This is transshipment in e way bill — one of the most routine yet most mismanaged events in India’s GST logistics chain. Nearly every consignment travelling transshipment of goods under e-way bill … any real distance will, at some point, change diver, vehicles, or modes of transport. Get the paperwork wrong at that moment, and a minor breakdown can turn into a Section 129 detention notice.
This guide covers the rule as it has stood since 2021, and layers in what has materially changed on the GSTN portal through 2026.
What is Transshipment of Goods Under E-Way Bill?
Transshipment refers to a change in the vehicle or the mode of conveyance while goods are still in transit, before delivery is complete.. Transshipment of goods under e way bill typically arises in the following situations:
- A shift from one mode of transport to another (for example, rail to road)
- A shift from a larger vehicle to a smaller vehicle for last-mile delivery
- An unplanned vehicle breakdown requiring an e way bill vehicle change before transportation resumes
What is NOT Transshipment in E-Way Bill?
Not every movement of goods or operational change qualifies as transshipment in e way bill. The following situations do not qualify as transshipment under the GST e-way bill provisions. Therefore, you do not need to update the vehicle details in the e-way bill.
- Goods have already reached the final place of delivery.
- Only the driver changes while the same vehicle continues transporting the goods.
- Temporarily halting or parking the vehicle during transit without changing the conveyance does not count as transshipment.
- Transporter handles or stores the goods within the same warehouse without transporting them further.
- Administrative corrections that do not involve a change in the vehicle or mode of transport.
Legal Requirements for E Way Bill Vehicle Change Under GST
Rule 138 of the CGST Rules governs every e-way bill vehicle change. Businesses must understand when to update Part B of e way bill instead of generating a fresh EWB. Any consignment valued above Rs. 50,000 requires an e-way bill before movement begins, and the document must travel with the goods until delivery. Where transshipment occurs, the law does not require a fresh e-way bill. It requires the taxpayer or transporter to update Part-B of the existing e-way bill with the new vehicle number, the reason for the change, and the relevant transporter details, either on the portal or via the SMS facility.
When an Update Is Not Required
Two narrow exceptions exist. First, you do not need to update the e-way bill when goods move by a non-motorised conveyance, such as a bullock cart, during any leg of the journey. Second, where the distance between the place of the supplier and the place of the recipient is less than 50 kilometres and the movement is within the same state. Outside these two carve-outs, Part-B must be updated every time the vehicle or mode changes.
Common Scenarios Requiring Part B Updates in the E-Way Bill
| Situation | Update Required? | Reason |
|---|---|---|
| Vehicle breakdown | Yes | Update the vehicle number in the e-way bill before resuming transit. |
| Last-mile delivery using another vehicle | Yes | The vehicle has changed during transportation. |
| Goods shifted to another truck | Yes | Update the vehicle details in the e-way bill. |
| Rail to truck / Road to rail movement | Yes | The mode of transport has changed. |
| Driver changed only | No | The vehicle remains the same, so no update is required. |
| Goods unloaded temporarily without changing the conveyance | No | There is no change in the vehicle or mode of transport. |
| Goods split into multiple vehicles | Yes | Update the e-way bill to reflect multi-vehicle movement as applicable. |
Step-by-Step Process for Transshipment Under E-Way Bill
Step 1: Access the E-Way Bill
Log in to the e-way bill portal and retrieve the relevant EWB number.
Step 2: Select the Movement Type
If you split the consignment across multiple vehicles, select the Multi-Vehicle Movement option.
Step 3: Verify Movement Details
Confirm the origin, destination, and quantity of goods transported in each vehicle.
Step 4: Update Part-B
For a one-to-one vehicle replacement, update Part-B with:
- The new vehicle number
- A valid reason code (Breakdown, Transshipment, or Route Change)
Step 5: Complete the Vehicle Update
You can update Part B of the e-way bill multiple times before it expires. The portal records every update and creates a complete movement trail for tax authorities if they intercept the consignment.
Step 6: Transporter Access
When the e-way bill includes the Transporter ID, the transporter—not just the original taxpayer—can update Part B directly.

2026 Update: What Has Changed for Transshipment Compliance
The GST portal has followed the same core transshipment process since 2021. What has changed is the compliance environment surrounding every Part-B update, From 1 August 2026, GSTN mandates the Ship-To GSTIN wherever Bill-To/Ship-To transactions exist. Businesses handling transshipment should ensure consistency between invoice data and Ship-To GSTIN throughout the movement lifecycle. requested more time for ERP readiness.
Dual Portal Synchronisation, the e-way bill system now runs on a dual-portal architecture, referred to informally as E-Way Bill 2.0, where the original portal and the newer system sync data automatically. This matters directly for transshipment of goods under e-way bill because a Part-B update made on either portal now reflects on both, reducing the downtime risk that used to strand transporters when one portal was slow.
Mandatory Ship-To GSTIN, From 1 August 2026, taxpayers must enter the Ship-To GSTIN wherever Bill-To/Ship-To details are available. If the consignee is unregistered, enter “URP” in the Ship-To GSTIN field. For consignments that pass through a warehouse or hub before reaching a delivery location different from the one mentioned on the invoice, keep the Ship-To GSTIN consistent in every Part B update. Any mismatch between the Ship-To GSTIN and the recipient GSTIN on the invoice can trigger scrutiny under Section 129.
Voluntary E-Way Bill Closure, GSTN has introduced a voluntary E-Way Bill Closure facility. Once goods are actually delivered, the supplier, recipient, transporter, or the driver linked to the registered mobile number can formally close the e-way bill, on the day of delivery or the day after. For multi-leg transshipped consignments, this creates, for the first time, a system-verified end point to the movement trail, rather than relying on the e-way bill simply expiring.
Multi-Factor Authentication, access itself has tightened. Since April 2025, the portal has required multi-factor authentication (MFA) for login, and this requirement remains in effect in 2026. The portal also automatically blocks e-way bill generation for GSTINs with pending returns or cancelled registrations. As a result, a taxpayer transporting goods may be unable to update Part B during transshipment if they fail to file a return on time.

Compliance Risks and Penalties During E-Way Bill Movement
Non-compliance — an expired e-way bill, an un-updated Part-B, or a missing Ship-To GSTIN after August 2026 — exposes the consignment to detention under Section 129, with a penalty equal to the tax evaded or Rs. 10,000, whichever is higher, in addition to potential seizure of the vehicle. Transporters should note that an expired e-way bill’s vehicle details cannot be updated at all; Businesses should also monitor e way bill validity after vehicle change and extension has to happen within the window running from eight hours before to eight hours after expiry.
How GSTrobo’s E-Way Bill Software Helps
Consider a business moving ten consignments from Delhi into Karnataka, destined for Bangalore, Mysore, and Udupi. After the truck reaches the Karnataka godown, each consignment is reassigned to a smaller vehicle, and Part-B needs updating ten times over. GSTrobo’s automated e way bill software auto-extend feature was built for exactly this scenario, renewing validity automatically before expiry.
In 2026, GSTrobo’s auto-extend capability now works alongside dual-portal synchronisation and can be configured to flag Ship-To GSTIN fields before submission and to trigger closure once delivery is confirmed — turning a manual, error-prone chore into a monitored, audit-ready e way bill software workflow.
