Ruling on Mud Engineering Services: Classification, GST Rates, and Concessions

The supply of mud engineering services along with imported mud chemicals and additives provided on a consumption basis was ruled not to qualify as a composite supply. As a result, the supplies should be classified independently under their respective HSNs for goods/services, with applicable GST rates levied accordingly. The supply of mud chemicals and additives on a consumption basis qualifies for a concessional GST rate of 5% under a specific Customs Notification, subject to meeting specified conditions and approval by the Proper Officer.

Issues Involved:
1. Whether the supply of mud engineering services along with supply of imported mud chemicals and additives provided on a consumption basis qualifies as a composite supply.
2. If the answer to the first issue is yes, whether the supplies made under the contract merit classification under Entry 9986(ii) - Service of exploration, mining, or drilling of petroleum crude or natural gas or both, and are subject to GST at the rate of 12%/18%.
3. If the answer to the first issue is no, whether the supply of mud chemicals and additives on a consumption basis at OIL India's location in India qualifies for a concessional GST rate of 5% against an Essentiality Certificate under Notification No. 50/2017-Customs dated 30 June 2017.

Issue-wise Detailed Analysis:

Issue 1: Composite Supply Qualification
The applicant, Halliburton Offshore Services Inc., sought a ruling on whether their contract for providing mud engineering services along with the supply of imported mud chemicals and additives qualifies as a composite supply under Section 2(30) of the CGST Act, 2017. The term "composite supply" is defined as a supply made by a taxable person to a recipient consisting of two or more taxable supplies of goods or services or both, which are naturally bundled and supplied in conjunction with each other in the ordinary course of business, one of which is a principal supply.

The authority examined the contract between the applicant and OIL India Limited, which included the provision of mud engineering services, supply of mud chemicals, and additives. The contract's scope indicated that these supplies are essential for performing the services but can be procured independently. The authority concluded that the supplies of mud chemicals and additives are not necessarily provided in conjunction with the services, as they can be delivered, replaced, and demobilized independently. Therefore, the supply of mud engineering services along with the supply of imported mud chemicals and additives does not qualify as a composite supply.

Issue 2: Classification Under Entry 9986(ii)
Since the answer to the first issue was no, the necessity of classifying the supplies under Entry 9986(ii) does not arise. The authority stated that the supplies should be classified independently under their respective HSNs of services/goods, and the applicable GST rates should be levied accordingly.

Issue 3: Concessional GST Rate of 5%
The applicant also sought a ruling on whether the supply of mud chemicals and additives on a consumption basis at OIL India's location qualifies for a concessional GST rate of 5% against an Essentiality Certificate under Notification No. 50/2017-Customs. The authority referred to its earlier finding that the supply of mud chemicals and additives should be classified as the supply of goods. Therefore, the benefits under the referred Customs Notification are available to the supply of such goods at the time of their importation, subject to the fulfillment of the description, tariff item, lists, and conditions specified therein and to the satisfaction of the Proper Officer.

Ruling:
1. The supply of mud engineering services along with the supply of imported mud chemicals and additives provided on a consumption basis by the applicant does not qualify as a composite supply.
2. Since the answer to the first question is no, the classification under Entry 9986(ii) does not apply.
3. The supply of mud chemicals and additives on a consumption basis qualifies for a concessional GST rate of 5% against an Essentiality Certificate under Notification No. 50/2017-Customs, subject to the fulfillment of specified conditions and the satisfaction of the Proper Officer.
