Issues Involved:
1. Classification of the product "Dialyzer" under GST law.
2. Determination of the applicable tariff heading for "Dialyzer" under GST law.

Issue-Wise Detailed Analysis:

1. Classification of the product "Dialyzer" under GST law:

The applicant, M/s. Nipro India Corporation Private Limited, sought an advance ruling to determine whether the product "Dialyzer" should be treated as a 'Disposable sterilized dialyzer or micro barrier of artificial kidney' under Entry No. 255 of Schedule I to Notification Number 1/2017-Central Tax (Rate) and Notification Number 1/2017-Integrated Tax (Rate).

The applicant argued that the "Dialyzer" is a medical equipment used in dialysis machines for blood purification, separating blood impurities like urea and creatinine through a semi-permeable membrane. They contended that the product qualifies as a 'Disposable sterilized dialyzer or micro barrier of artificial kidney' under the specified entry.

The Authority examined the product's function and usage, noting that "Dialyzers" are used exclusively in dialysis machines for blood purification and not for filtration or purification of other liquids or gases. The Authority concluded that the product is indeed a disposable, sterilized medical apparatus used in dialysis machines and thus falls under the description provided in Entry No. 255 of Schedule I to the Rate Notifications.

2. Determination of the applicable tariff heading for "Dialyzer" under GST law:

The second issue was whether the "Dialyzer" should be classified under Chapter 90 (Tariff item 9018 90 31) or Chapter 84 (Tariff item 8421 29 00). The applicant argued that the product should be classified under Chapter 90, specifically under Tariff item 9018 90 31, which covers renal dialysis equipment, including artificial kidneys and dialyzers.

The Authority considered the competing tariff headings:
- Heading 9018 covers instruments and appliances used in medical, surgical, dental, or veterinary sciences, including renal dialysis equipment.
- Heading 8421 covers filtering or purifying machinery and apparatus for liquids or gases.

The Authority noted that the "Dialyzer" is specifically mentioned under Heading 9018 as renal dialysis equipment. They also referred to the Customs Tariff Act, 1975, which lists "Dialyzers" under Tariff item 9018 90 31. Given the specific mention in Chapter 90 and the principle that a specific heading should be preferred over a generic one, the Authority concluded that the "Dialyzer" should be classified under Tariff item 9018 90 31.

The Authority also addressed the ambiguity arising from Board’s Circular No. 19/2013, which suggested classification under Heading 8421. They clarified that in case of conflict between a circular and an Act of Parliament, the Act prevails. Thus, the product should be classified under the specific heading provided in the Customs Tariff Act.

Order:

1. The product "Dialyzer" is treated as a 'Disposable sterilized dialyzer or micro barrier of artificial kidney' under Entry No. 255 of Schedule I to the Rate Notifications.
2. The product "Dialyzer" is classifiable under Chapter 90, specifically under Tariff item 9018 90 31.
