The short version
- Company asked if surgical microscopes qualify as medical equipment under CTH 9018.
- Gujarat AAR confirmed classification under CTH 9018 attracting 5% GST rate.
- Specialized surgical microscopes are excluded from general optical equipment under CTH 9011.
In short
The company sold specialized eye surgical microscopes equipped with motorized zoom and red reflex illumination for eye operations. They asked whether these machines are general optical microscopes or specialized medical instruments for Goods and Services Tax (GST) purposes. Tax rates differ significantly between standard laboratory equipment and medical devices.
What has changed
How it worked before
Suppliers were often uncertain whether surgical microscopes fell under general optical equipment or medical instruments. Some tax officers argued that all microscopes belong under general optical equipment, risking higher tax demands.
What has changed
The Gujarat Authority for Advance Ruling (AAR) decided under ruling GUJ/GAAR/R/2026/27 that specialized eye surgical microscopes fall under tariff heading 9018 as medical instruments. This allows the product to qualify for a lower 5% GST rate (2.5% CGST and 2.5% SGST) under Notification No. 09/2025-Central Tax (Rate). General optical microscopes used in labs or schools do not get this lower rate.
Who this affects
Medical device manufacturers, importers, and distributors selling specialized surgical equipment to hospitals.
An example
A medical equipment dealer in Surat imports binocular microscopes specifically designed for cataract surgeries. The dealer wants to charge 5% GST rather than the higher rates meant for general laboratory microscopes. Following the logic of this ruling, because the equipment is designed exclusively for surgical procedures, it qualifies as a medical instrument under heading 9018. However, the dealer must present clear technical product catalogues to their tax officer or apply for their own ruling to ensure certainty.
What you should do
If you sell specialized surgical microscopes, review how you classify them on your tax invoices. Remember that an advance ruling binds only the company that applied and its local tax authority. To get guaranteed legal protection for your own business, you should apply for an advance ruling yourself.
If you do nothing
If you charge 5% GST assuming this ruling covers your business automatically, a tax officer may disagree during an audit. They could classify your equipment under general optical devices and demand the tax difference along with interest and penalties. Relying on someone else's advance ruling without formal confirmation offers no legal protection.

Questions before the authority
- Whether the product, in question, Ophthalmic Binocular Surgical Microscope shall merit classification under the CTH 9018 of the Custom Tariff Act, 1975 or otherwise?
- Whether the goods Ophthalmic Binocular Surgical Microscope fall within the Sr.No.483 of Schedule-I of Notification No. 9/2025-CT (Rate) dated 17.09.2025 or otherwise?
Facts
The applicant is engaged in the supply of Ophthalmic Binocular Surgical Microscopes used by eye surgeons for examining and operating on the anterior and posterior segments of the human eye. The equipment provides a magnified, three-dimensional stereoscopic view and incorporates advanced surgical features such as motorized zoom, red reflex illumination, and electromagnetic locking systems. The applicant sought an advance ruling regarding the HSN classification and applicable GST rate for this specialized surgical product.
Ruling
| Question | What the authority ruled |
|---|---|
| Classification of Ophthalmic Binocular Surgical Microscope | Classifiable under CTH 9018 of the First Schedule to the Customs Tariff Act, 1975 Excludes CTH 9011 and 9012 as per HSN Explanatory Notes |
| Applicability of Sr. No. 483 of Schedule-I of Notification No. 09/2025-CT (Rate) | Falls under Sr. No. 483 of Schedule-I, taxable at 5% GST (2.5% CGST + 2.5% SGST) None |
The Authority held that the Ophthalmic Binocular Surgical Microscope is classifiable under **CTH 9018** of the First Schedule to the Customs Tariff Act, 1975. Consequently, the product is covered under **Sr. No. 483 of Schedule-I** of Notification No. 09/2025-Central Tax (Rate), attracting GST at the concessional rate of **5% (2.5% CGST + 2.5% SGST)**.
Reasoning
The Authority analyzed the Chapter Notes and HSN Explanatory Notes for Chapter 90, observing that HSN Explanatory Notes to heading 9011 explicitly exclude 'Ophthalmic binocular-type microscopes (heading 90.18)'. While headings 9011 and 9012 cover generic optical and non-optical microscopes used for general, educational, or industrial research, heading 9018 covers specialized instruments used in professional medical and surgical practice. Applying Rule 3 of the General Rules for Interpretation, heading 9018 provides the most specific description for an instrument solely intended for eye surgeries. Therefore, the product is properly classifiable under CTH 9018 and eligible for the 5% GST rate under Sr. No. 483 of Schedule-I.
Provisions relied on
- Heading 9018 of the First Schedule to the Customs Tariff Act, 1975
- Heading 9011 of the First Schedule to the Customs Tariff Act, 1975
- Heading 9012 of the First Schedule to the Customs Tariff Act, 1975
- Rule 3 of General Rules for Interpretation
- Notification No. 09/2025-Central Tax (Rate) dated 17.09.2025 (Sr. No. 483 of Schedule-I)
For the practitioner
This ruling confirms that **specialized surgical microscopes** designed exclusively for medical and surgical procedures qualify as medical instruments under **CTH 9018** rather than general optical equipment under CTH 9011/9012. Practitioners can rely on the explicit exclusions in HSN notes to defend the lower 5% GST rate for specialized ophthalmic surgical equipment. It does not decide the classification of standard optical microscopes used in non-surgical or laboratory environments.
