A single error on your invoice could lead to costly penalty notices and tax filing hurdles. For those in the Indian transport and logistics sector, the SAC code (Services Accounting Code) is the vital link to ensuring your GST is handled correctly.
Using an incorrect code can block your customers’ Input Tax Credit (ITC), trigger audit scrutiny, and result in inaccurate tax payments. Whether you move goods via road, rail, air, or water, the classification rules are precise. This guide simplifies the process: we provide the exact codes you need, explain how GST rates vary based on your ITC preference, and help you maintain seamless compliance on every invoice.

What is the HSN code for transportation services?
The HSN code for transportation refers to the numerical classification system used under GST to identify and tax services related to the movement of goods and passengers across India. Although HSN (Harmonised System of Nomenclature) traditionally classifies physical goods, the same numerical structure—commonly referred to as SAC (Services Accounting Code) in professional practice—is utilised for services.
The primary heading for transport services is 9965. Accurately applying the correct 6-digit code to your tax invoices is essential for precise GST filing, determining the appropriate tax rate, and ensuring your business remains fully compliant with the latest tax regulations.
HSN/SAC codes for different modes of transport
Transportation services are classified under the HSN/SAC system, specifically within the primary heading 9965. The precise 6-digit code is determined by the mode of transport utilised. Below are the primary SAC codes for various transportation services as of 2026:
Primary SAC codes for transport services (2025-26)
| Mode of transport | Service description | HSN/SAC code | GST rate (Indicative) |
|---|---|---|---|
| Road transport | Goods transport by road (GTA, freight forwarding) | 996511 | 5% (no ITC) or 12% (with ITC) |
| Rail transport | Goods transport by rail | 996512 | 5% (with limited ITC) |
| Air transport | Domestic air cargo services | 996531 | 18% (with ITC) |
| Water transport | Goods transport by inland and coastal waters | 996521 | 5% (no ITC) or 18% (with ITC) |
| Pipeline transport | Transport of oil, gas, or water via pipeline | 996513 | 18% (with ITC) |
| Passenger transport | Road transport (e.g., AC buses, radio taxis) | 996411 | 5% (no ITC) |
Key takeaway: For the majority of goods transport via road, rail, air, or water, the primary codes are 996511, 996512, 996531, or 996521, respectively. The applicable GST rate is largely determined by whether the transporter elects to claim Input Tax Credit (ITC).
HSN code for transportation charges
When a transporter issues an invoice, it often includes various supplementary costs beyond the basic freight. Under GST regulations, these are typically treated as a composite supply, where the primary transportation service governs the classification. Consequently, most associated charges fall under the same 6-digit SAC code (e.g., 996511 for road transport).
Classification of common transportation charges
- Freight charges (Carriage inwards/outwards): This represents the core cost of moving goods. It is classified under the primary SAC code for the specific mode of transport (e.g., 996511 for road or 996512 for rail).
- Loading and unloading charges: As these activities are essential to the transport process, they are generally considered part of the primary supply. They do not require a separate code and are taxed at the same rate as the main freight service.
- Handling and forwarding charges: These are ancillary to the main transport service and are classified under the same SAC code as the principal service.
- Demurrage and detention charges: These are fees levied for delays beyond the agreed-upon timeframe. Under GST, these are treated as part of the composite supply of transport and attract the same tax rate as the primary service.
Crucial rule: If multiple charges form a single, composite supply where transportation is the principal service, the entire invoice value is classified under the SAC code for that specific transport service.
GST rates for transportation services (with and without ITC)
A unique feature of GST on transportation services in India is that the applicable tax rate is determined by the transporter’s decision regarding Input Tax Credit (ITC). The two primary frameworks for the 2025-26 financial year are:
GST rate options for transporters
- Option 1: Concessional rate (without ITC): Transporters may elect to pay GST at a reduced rate of 5%. However, under this provision, they are prohibited from claiming ITC on business overheads, such as fuel, vehicle spares, tyres, or maintenance services.
- Option 2: Standard rate (with ITC): Alternatively, transporters can opt for a 12% GST rate. This selection allows the business to claim full Input Tax Credit on all GST-compliant business expenses, including the purchase of new commercial vehicles and high-value maintenance.
Strategic selection: which framework suits your business?
- Small fleet operators: Businesses with lower overheads or those who primarily procure non-GST-compliant inputs may find the 5% (without ITC) model simpler and more cost-effective for their cash flow.
- Large-scale logistics firms: Operators managing extensive fleets with significant ITC-eligible capital expenditure (such as new truck fleets or automated warehousing) typically prefer the 12% (With ITC) model. This often results in a lower effective tax burden by offsetting outward liability against input taxes paid.
Crucial requirement: This election must be made at the commencement of the financial year and applied consistently across all services. While the SAC code remains unchanged, the applied tax rate serves as the primary differentiator.
Importance of using the correct HSN code for transportation
The precise application of the SAC code (Services Accounting Code) for transportation is far more than a mere administrative detail; it carries significant financial and legal implications. Ensuring accuracy in your invoicing is critical for the following reasons:
- Accurate GST liability: The SAC code directly dictates the applicable GST rate. An error here could lead to the incorrect calculation of tax, resulting in either the short-payment of dues or unnecessary over-payment.
- Mitigating penalties and scrutiny: Mismatched or erroneous codes on tax invoices and GSTR-1 returns are frequent triggers for GST department audits and penalty notices. Inaccurate classification can be viewed as a compliance failure by the authorities.
- Ensuring ITC for your clients: Your customers rely on the correct SAC code appearing on your invoices to claim their Input Tax Credit (ITC). A clerical error on your part could block their credit, leading to strained business relationships and potential payment delays.
- Eligibility for concessional schemes: Transporters opting for specific GST frameworks, such as the composition scheme or the 5% (No ITC) model, must utilise the correct codes to remain eligible and correctly classified.
- Precise financial reporting: Accurate classification facilitates a clearer analysis of your revenue streams and operational overheads, aiding in more robust financial planning and informed business decisions.
How to find the correct HSN code for your transportation service
If you are uncertain about the correct SAC code for your specific transportation service, here are the most reliable methods to identify and verify the appropriate classification:
- Consult the official GST portal: The GST portal and the CBIC (Central Board of Indirect Taxes and Customs) website provide official notifications and rate schedules. These resources list all HSN/SAC codes alongside their formal descriptions and current tax rates.
- Refer to GST rate notifications: Review the specific notifications for services. Transportation is primarily governed by Notification No. 11/2017 – Central Tax (Rate) and its subsequent amendments for the 2025-26 and 2026-27 financial years.
- Define your primary service: Clearly identify your core operation. Is it road haulage (GTA), passenger transport, or air cargo? This will direct you to the relevant sub-heading under Chapter 99 (Services).
- Examine inbound invoices: If you are a recipient of transport services, your provider’s tax invoice must state the HSN/SAC code. This serves as a practical reference for your own accounting.
- Seek professional advice: Consult your Chartered Accountant (CA) or a GST expert. A qualified advisor possesses the technical expertise to ensure your service classification is accurate and fully compliant with the latest tax laws.
Conclusion
Applying the correct SAC code for transportation is a cornerstone of robust financial management and GST compliance. By accurately classifying your logistics activities, your firm can streamline its operations, mitigate audit risks, and ensure seamless tax filing.
