Replacement of copper scrap with enameled copper winding wire constitutes supply of goods not services under HSN 8544

AAR Tamil Nadu ruled that replacement of copper scrap with enameled copper winding wire constitutes supply of goods, not services. The transaction involves two independent supplies - inward supply of copper scrap and outward supply of enameled copper wire. Enameled copper winding wire classified under HSN 8544 11 10 attracts 18% GST. The arrangement does not qualify as composite supply since only one outward supply occurs. Applicant not liable for RCM on copper scrap purchases from unregistered motor mechanics, as current notifications only cover promoters/builders for RCM obligations on unregistered supplier transactions.

ISSUES PRESENTED AND CONSIDERED

1. Whether the applicant's activity of receiving copper scrap and supplying pre-processed enameled winding wire in exchange constitutes a supply of goods or a supply of services under the GST law.

2. If treated as supply of goods, the appropriate tax classification and rate (HSN/SAC and IGST/CGST+SGST applicable).

3. Whether the transaction constitutes a composite supply.

4. Whether reverse charge mechanism (RCM) applies to purchases of old copper scraps from unregistered motor mechanics, and if so, the applicable rate and availability of input tax credit (ITC) on tax paid under RCM.

5. Whether queries about procedures and documents for movement of goods between hub and factory fall within the scope of matters on which an advance ruling may be sought.

ISSUE-WISE DETAILED ANALYSIS

Issue 1: Characterisation - Goods or Service

Legal framework: GST definition of "supply" and Schedule II entries treating "treatment or process" on another person's goods as supply of services; definition of "job work" (treatment on goods belonging to another registered person).

Precedent treatment: No contemporaneous judicial or administrative precedent cited or relied upon in the text.

Interpretation and reasoning: The Authority examined the contractual and factual matrix: (a) the applicant takes title/possession of scrap (inward supply) and does not process and return the same specific goods to the same customer; (b) manufacturing and enameling are carried out by the applicant on goods that become its own inputs for future sales; (c) treatment/process under Schedule II is confined to processes applied to another person's goods (i.e., where title remains with the principal and work is undertaken at the principal's behest); (d) job-work requires the goods to belong to another registered person and to be processed on their behalf. Here, none of those conditions are met - the activity is self-driven manufacturing and subsequent sale of finished enameled wire, and the inward and outward legs are independent.

Ratio vs. Obiter: Ratio - The transaction is an outward supply of goods because the applicant manufactures and supplies finished enameled winding wire and the scrap receipt is an independent inward supply; the activity is not a service nor job work. Obiter - Observations on analogy with battery recharge and app-based intermediaries are ancillary.

Conclusion: The activity constitutes sale of goods, not supply of services.

Issue 2: Classification and Tax Rate (HSN/SAC and Rate)

Legal framework: GST Tariff chapter headings and sub-headings; classification principles distinguishing plain copper wire from enameled/insulated variants.

Precedent treatment: None cited.

Interpretation and reasoning: The Authority noted that enameled winding wire has an enamel coating providing electrical insulation and specific thermal/chemical resistance and thus is functionally and technically distinct from plain copper wire. Consequently, it fits the tariff description for insulated electric conductors rather than plain copper wire classifications.

Ratio vs. Obiter: Ratio - Enameled copper winding wire classifies under the tariff sub-heading for insulated electric conductors. Obiter - Technical notes on insulation function and purpose support but are illustrative.

Conclusion: Enameled copper winding wire is classifiable under HSN 8544 11 10 and attracts IGST at 18% (or CGST 9% + SGST 9%).

Issue 3: Composite Supply

Legal framework: Definition of "composite supply" - a supply consisting of two or more taxable supplies naturally bundled and one being a principal supply, supplied in conjunction in the ordinary course of business.

Precedent treatment: None cited.

Interpretation and reasoning: The Authority found only one outward supply (manufactured enameled wire) is made to customers; the receipt of scrap is an inward supply to the applicant and not an outward supply bundled with sale of wire. The internal processes (manufacture/enameling) are carried out by the applicant for its own inventory, not at the customer's direction, so there are not multiple taxable supplies made to the same recipient that are naturally bundled.

Ratio vs. Obiter: Ratio - The transaction does not constitute a composite supply because there is a single outward supply of goods and internal processing/inward receipt are not components of a bundle supplied to the same recipient. Obiter - Comparison with the illustrative example in the definition clarifies the application.

Conclusion: The transaction does not come under "composite supply".

Issue 4: Applicability of Reverse Charge Mechanism (RCM) on Purchases from Unregistered Motor Mechanics; Rate; ITC on RCM Paid

Legal framework: Section providing for RCM as originally enacted; notifications granting exemptions from RCM for supplies from unregistered persons; statutory amendment rewording RCM to permit notifications specifying classes of registered persons liable to RCM.

Precedent treatment: None cited; Authority traced legislative and notification history.

Interpretation and reasoning: The Authority reviewed the temporal evolution: initial RCM on purchases from unregistered persons with a threshold; subsequent notifications granting blanket exemption from suppliers who are unregistered; amendment to Section which confined RCM liability to classes of registered persons specified by notification. Only a limited class (promoters/builders) has since been notified as liable under RCM for certain supplies. Absent a notification bringing the applicant within a notified class, RCM on purchases from unregistered motor mechanics does not apply.

Ratio vs. Obiter: Ratio - RCM is not applicable to the applicant's purchases of old copper scrap from unregistered suppliers because the statutory scheme now limits RCM to notified classes and the applicant is not a notified class. Obiter - Historical explanation of notifications and thresholds is explanatory.

Conclusion: RCM does not apply on purchases of old copper scrap from motor mechanics; consequently questions of RCM rate and ITC on RCM are not applicable.

Issue 5: Scope of Advance Ruling - Query on Movement Documents between Hub and Factory

Legal framework: Scope of matters admissible for advance ruling under list of clauses in the statute (matters such as classification, time/value of supply, liability, whether particular thing amounts to supply).

Precedent treatment: None cited.

Interpretation and reasoning: The Authority observed that the applicant's query on procedures/documents for movement of goods between hub and factory does not fall within any enumerated clause permitting an advance ruling under the statute and therefore is outside the jurisdictional scope for advance ruling.

Ratio vs. Obiter: Ratio - Questions outside the statutory list (procedural/documentary formalities for movement between places of business) are not answerable by advance ruling. Obiter - None.

Conclusion: The query on movement-related procedures/documents is not covered under the advance ruling provisions and is not answered.
