SC on Classification

The Hon'ble Supreme Court of India has consistently held that parts integral or essential to an article or machinery should generally be classified according to the classification of the main article or machinery. This principle is crucial for customs and excise duties, ensuring consistency and preventing components from being classified independently under broader categories.

Key Legal Principles Established by the Supreme Court:

1. Principal Use Test: If a part is specifically designed for and solely or principally usable with a particular article or machinery, it should be classified with that article or machinery. This test can override general exclusionary notes.

2. Commercial Identity Test: Classification should be based on how goods are commercially identified and understood in the market, rather than solely on their functional attributes.

3. Essential Character Test (GRI Rule 2(a)): Parts that, even if incomplete or unassembled, possess the essential character of the complete article, are classified as the complete article.

4. Functional Integration Test: Parts functionally integrated and essential for the operation of the main machinery are classified under the same heading as the main machinery.

5. Timing of Import Irrelevant: Parts meant for the same complete equipment are treated together for classification, regardless of when they are imported.

6. Consideration of Technical Specifications: Courts consider industry standards and technical specifications to determine essential parts.

Landmark Case Laws Illustrating These Principles:

• G.S. Auto International Ltd. v. Collector Of Central Excise, Chandigarh (2003): Emphasized the "commercial identity test," holding that specialized automobile components (e.g., specific bolts, nuts) are classified as motor vehicle parts, not general fasteners. This case highlighted that parts specifically designed for and solely or principally usable with a particular article should be classified with that article.

• Westinghouse Saxby Farmer Ltd. v. CCE, Calcutta (2022): Reinforced the "principal use test," ruling that relays designed solely for railway signalling systems are classified with railway equipment (Chapter 86), even if they could generally fall under electrical apparatus (Chapter 85). This case clarified that the principal use test can override general exclusionary notes.

• Boskalis Dredging India Pvt. Ltd. v. Commissioner of Customs, Bhubaneswar (2002) & Dharti Dredging and Infrastructure Ltd. v. Commissioner of Customs and Central Excise, Guntur (2023): Both cases affirmed that integral and indispensable components of a dredger (e.g., pipelines, pontoons, pumping units) are classified with the dredger, even if imported separately or having potential independent uses. The test is whether these parts are essential for the purpose of the main equipment.

• Hindustan Motors Limited case (2005): Held that unassembled engine component sets, possessing the essential character of complete engines, are classified as complete engines under GRI Rule 2(a).

• Sharp Business Machines Pvt. Ltd. v. Collector of Customs, Bangalore (1990): Established principles for classifying components imported in SKD/CKD (Semi-Knocked Down/Completely Knocked Down) condition as complete machines.

• Commissioner Of Central Excise, Delhi v. Insulation Electrical Private Limited: Distinguished between "essential parts" and "accessories," holding that components merely enhancing functionality or comfort (like certain seat mechanisms) are accessories, not essential parts.

• Uni Products India ltd: Classified 'car mattings' as "carpets" (a more specific description) rather than parts of cars, demonstrating that a specific description in another chapter can prevail even if designed to fit a particular machine.

• Plasmac Machine Manufacturing Co. Pvt. Ltd. v. Collector Of Central Excise, Bombay (1990): Classified specialized "Tie Bar Nuts" for injection moulding machines as general fasteners, emphasizing commercial understanding and functionality over exclusive design. This case shows a nuanced tension with later rulings that prioritize "sole/principal use."
