Engineering, procurement, and construction contractors, plant installers, and technical testing agencies frequently transport high-value equipment between workshops and customer sites. Highway patrol officers routinely inspect flatbed trailers carrying heavy machinery and scrutinize the absence of a tax invoice. If your documentation misses statutory delivery challan disclosures or portal sub-types, state mobile squads issue physical detention orders under Section 129 of the Central Goods and Services Tax Act.
Operating safely requires strict adherence to the transportation framework under Rule 138 of the CGST Rules and the documentation mandate prescribed in Rule 55(1)(c) of the CGST Rules. Understanding how the e-way bill system records non-supply capital asset transfers protects your project from operational disruption and severe statutory penalties.
Why non-supply asset movements require an e-way bill
In practice, a common operational misconception among field engineers is that e-way bills apply only to sold merchandise. Section 68 of the CGST Act mandates that the person in charge of a conveyance carrying goods exceeding prescribed thresholds must carry statutory documents. Rule 138(1) explicitly states that an e-way bill must be generated before commencement of movement of goods of consignment value exceeding Rs 50,000, whether such movement is in relation to a supply, for reasons other than supply, or due to inward supply from an unregistered person.
When you send an excavator, a tower crane component, or testing instrumentation to a client premises, title in those goods remains with you. No consideration passes for the transfer of the assets themselves. Under statutory definitions, this relocation represents a movement for reasons other than supply. An e-way bill remains mandatory, supported by a formal delivery challan rather than a tax invoice.
Common mistake: Moving heavy machinery with a simple internal gate pass or lorry receipt without generating an e-way bill. If intercepted, field tax officers treat the consignment as undocumented transit, levying a 200 percent penalty under Section 129 of the CGST Act based on the estimated market value of the equipment.
Statutory rules for delivery challans under Rule 55(1)(c)
Rule 55 of the CGST Rules provides the legal mechanism for moving goods without an immediate tax invoice. Specifically, Rule 55(1)(c) authorizes the removal of goods for reasons other than supply, provided the sender issues a serially numbered delivery challan. To maintain validity during physical verification by mobile squads, your delivery challan must satisfy Rule 55(2) by containing the following particulars:
- Date and unique serial number of the delivery challan, consecutive across the financial year.
- Name, registered address, and GSTIN of the consignor originating the asset transfer.
- Name, address, and GSTIN (or Unique Identity Number) of the recipient or project site client.
- Harmonized System of Nomenclature code and technical description of each machine or tool.
- Exact quantity, unit of measurement, and identifiable chassis, engine, or serial numbers.
- Taxable value of the machinery, reflecting standard book value or fair market assessment.
- Applicable rate of tax and breakdown of CGST, SGST, or IGST for calculation of transit value.
- Place of supply and explicit declaration that goods are moving temporarily for site execution.
Step-by-step portal generation on ewaybillgst.gov.in
Logging into the national e-way bill system at ewaybillgst.gov.in requires specific field entries to avoid generating a commercial sale document. Follow this portal workflow:
- Navigate to e-way bill entry: From the main dashboard, select e-Waybill and click Generate New.
- Select transaction types: Under Transaction Type, check Outward. Under Sub Type, select radio button Others or Line Sales. In the adjacent text box for Others, type Equipment for Site Work.
- Select document type: In Document Type dropdown, choose Delivery Challan. Enter your challan number and date.
- Fill dispatch details: Verify your base warehouse or factory GSTIN, state, and physical dispatch address in the Bill From and Dispatch From sections.
- Fill delivery details: In the Bill To section, enter the client or contractor GSTIN. In the Ship To section, enter the actual project site address and exact destination pin code. If the site is unregistered, use client GSTIN with site pin code.
- Enter item details: Enter asset HSN, description with serial numbers, quantity, and book value. Enter the standard GST rate (e.g. 18 percent) to calculate transit valuation correctly.
- Complete Part B: Enter transporter name, transporter ID, or vehicle registration number. Verify route distance and click Submit.
Inter-state movement and registration requirements
When an engineering firm moves equipment across state boundaries, jurisdictional officers frequently examine whether the contractor requires local GST registration in the destination state. If you are executing a pure works contract service or technical installation, the machinery serves as capital goods used for rendering services. Under gst.gov.in statutory guidelines, temporary movement of tools and plant to an execution site does not mandate separate GST registration in the destination state, provided the site does not form a fixed establishment with independent permanent human and technical resources.
Contractors operating across state lines must reference related procedures such as inter-unit stock transfer delivery challan rules when moving goods between company-owned branches, or sale on approval basis delivery challan procedures when sending demonstration equipment. For project execution, the e-way bill shows your home state GSTIN as the consignor and the client site as the delivery location.
Worked example: moving heavy piling rig to project site
Consider Maharashtra-based foundation contractor Western Piling Solutions moving a hydraulic piling rig and casing tools from their Navi Mumbai depot to a bridge construction site in Bharuch, Gujarat. The assets have a depreciated book value of ₹1,80,00,000 and move on two heavy multi-axle trailers.
| Consignment item | HSN code | Book value | Notional IGST (18%) | E-way bill document | Sub-type selected |
|---|---|---|---|---|---|
| Hydraulic Piling Rig Base Unit | 8430 10 00 | ₹1,25,00,000 | ₹22,50,000 | Delivery Challan DC-081 | Outward - Others |
| Rotary Drilling Drive & Kelly Bar | 8431 49 90 | ₹35,00,000 | ₹6,30,000 | Delivery Challan DC-082 | Outward - Others |
| Steel Casings & Boring Buckets | 7326 90 99 | ₹20,00,000 | ₹3,60,000 | Delivery Challan DC-083 | Outward - Others |
Total asset book value across the convoy amounts to ₹1,80,00,000 with a notional IGST calculation of ₹32,40,000. No tax invoice is issued because ownership does not change. Each trailer carries its specific delivery challan and matched e-way bill referencing the exact trailer registration number in Part B.
Return transit and breakdown replacement
Once foundation piling work finishes, the machinery must return to the home depot or move to a subsequent project site. Return movement requires identical procedural rigor:
Return to base depot: The site supervisor or the originating office issues a fresh delivery challan under Rule 55(1)(c) for inward movement. A new e-way bill is generated with the project site as Dispatch From and the workshop depot as Ship To. The transaction sub-type remains Outward - Others or Inward - Others, referencing the return of owned tools.
Breakdown during site execution: If a machine engine fails and requires depot overhaul, do not transport the replacement unit using the original e-way bill. Generate a fresh delivery challan and e-way bill for the replacement asset dispatched to site. Simultaneously, issue a separate delivery challan for the damaged asset returning to the repair shop. Combining multi-vehicle transshipment requires following multi-hop transshipment hub rules to update Part B vehicle numbers prior to vehicle transfers.
Preventing detention under Section 129
Under Section 129 of the CGST Act, transporting goods in contravention of GST rules exposes the owner to vehicle detention and a penalty equal to 200 percent of the applicable tax. For machinery valued at ₹1,80,00,000 with 18 percent tax (₹32,40,000), a 200 percent penalty demands a cash deposit of ₹64,80,000 before vehicle release.
Detention risk: Discrepancies between physical serial numbers on the machine plate and delivery challan text allow mobile squads to allege that high-value equipment is being moved for unrecorded sale. Ensure every serial number matches the challan exactly before departure. Review e-way bill detention Section 129 penalty payment procedures if intercepted.
CBIC Circular 64/38/2018-GST provides relief for minor clerical errors, limiting penalties to Rs 500 under Section 125 for minor typographical slips in vehicle numbers. However, total absence of an e-way bill or failure to produce a Rule 55 delivery challan does not qualify as a minor slip and triggers full Section 129 proceedings.
Reconciliation and accounting treatment in GST returns
Asset transfers under delivery challans do not appear in Table 4 of GSTR-1 because they do not constitute outward taxable supplies. However, serial numbers of all delivery challans issued during the tax period must be reported in Table 12 of Form GSTR-1 under the document summary section.
When sub-contractors hire machinery, rental invoices issued for machine usage represent taxable service supplies under HSN 9973. Rental charges are billed under separate tax invoices and appear in GSTR-1, feeding the customer GSTR-2B. Reconciling site billing with physical machine availability ensures audit-ready enterprise records.
Reconcile vendor invoices and site billing
Verify that transport freight bills, sub-contractor plant hire charges, and equipment repair invoices match your purchase ledger and GSTR-2B. In-browser matching checks every record locally without server uploads.

Frequently asked questions
Is an e-way bill mandatory when moving own machinery to a client site without sale?
Yes. Under Rule 138(1) of the CGST Rules, an e-way bill is required for any transportation of goods where consignment value exceeds Rs 50,000, even when the movement is for reasons other than supply. You must issue a delivery challan under Rule 55(1)(c) instead of a tax invoice.
Which transaction sub-type should be selected on the e-way bill portal?
Select Outward as the supply type. For the sub-type, select Others or Line Sales, enter 'Movement of equipment for site execution' in the remarks field, and choose Delivery Challan as the document type.
What document brings the machinery back to base after site work finishes?
The return journey requires a fresh return delivery challan under Rule 55 and a newly generated e-way bill. If the contractor maintains an additional place of business at the site, that site issues the delivery challan; otherwise, the contractor issues an Inward delivery challan from base.
Can mobile machinery move across state borders without registering a site GSTIN?
Yes, provided the contractor operates as an integrated service provider and the site does not constitute a fixed establishment. Machinery moves under Rule 55(1)(c) with base GSTIN in dispatch details and client site address in delivery details, without charging IGST on capital equipment.
How to avoid transit detention under Section 129 during equipment breakdown replacement?
Ensure the replacement unit moves under its own fresh delivery challan and e-way bill. The defective machine returning to base must also carry a separate return delivery challan with exact serial numbers to prevent interception under Section 129.
