The short version
- Dyna Automation asked for the GST classification of a steering unit.
- The authority classified the steering unit as a valve under Heading 8481.
- This classification excludes the item from being treated as a vehicle part.
In short
The company asked the Gujarat Authority for Advance Ruling (GAAR) to clarify the correct GST classification for a hydraulic orbital valve used in agricultural machinery. The core issue was whether this part should be taxed as a general valve or as a specific part of a vehicle or machine.
What has changed
How it worked before
Businesses were often uncertain whether to classify hydraulic steering units as general valves or as specific parts of the machinery they are installed in, leading to inconsistent tax treatment.
What has changed
The authority ruled that these valves fall under Tariff Heading 8481. In practice, this means the GST rate for that specific heading applies, regardless of the machine the valve is eventually used in.
Who this affects
Manufacturers and importers of hydraulic steering units and similar valve components.
An example
A company imports hydraulic valves for use in construction equipment and has been paying tax as if they were vehicle parts. After reading this ruling, they realize their product functions as a valve under Heading 8481. They should consult their tax advisor to see if this classification applies to their specific product before changing their tax filings.
What you should do
If you sell similar valves, review your current classification against Heading 8481. Remember that an advance ruling only binds the company that asked for it and their specific tax office; it is not a universal law for your business.
If you do nothing
If you apply this ruling to your business without confirming your specific product details, you risk misclassifying your goods. A tax officer may disagree with your interpretation during an audit, leading to demands for unpaid tax, interest, and potential penalties.

Facts
The applicant imported a product described as a Steering Unit (Hydraulic Orbital Valve) for use in agricultural harvesting machinery. They initially paid 28% IGST but sought a ruling on the correct classification, suggesting it should fall under Tariff Heading 8481. The applicant also requested a ruling on several other items but later restricted their application to the Steering Unit only.
Ruling
| Question | What the authority ruled |
|---|---|
| Steering Unit (Hydraulic Orbital Valve) | Tariff Heading 8481 Excluded from Section XVII and thus not classifiable as a vehicle part under 8708 |
The Authority ruled that the Steering Unit (Hydraulic Orbital Valve) is correctly classifiable under Tariff Heading 8481. Consequently, the GST rate applicable to Tariff Heading 8481 applies to the product. The Authority did not provide rulings on the other five questions as the applicant withdrew them.
Reasoning
The Authority determined that the product is a valve and falls under Heading 8481. It relied on Note 2(a) of Section XVI of the Customs Tariff Act, 1975, which prioritizes classification in the respective heading for goods included in Chapter 84. Furthermore, it noted that Note 2(e) of Section XVII excludes articles of heading 8481 from being considered parts of vehicles, thereby rejecting classification under 8708. The ruling also referenced HSN Explanatory Notes as a dependable guide for tariff interpretation.
Provisions relied on
- Section 97(2) of CGST/GGST Act, 2017
- Notification No. 1/2017-Central Tax (Rate) dated 28.06.2017
- Customs Tariff Act, 1975 (Section XVI Note 2, Section XVII Note 2(e))
- Tariff Heading 8481
- Tariff Heading 8431
- Tariff Heading 8708
For the practitioner
This ruling confirms that **Hydraulic Orbital Valves** are classifiable under **Tariff Heading 8481** rather than as vehicle parts under 8708 or machinery parts under 8431. It is useful for practitioners dealing with the classification of hydraulic components that function as valves. It does not decide the classification of the other items listed in the original application as those were withdrawn.
