R K Jain's Classification of Goods and Services under GST/Customs & other Indirect Tax Laws by Kishore Harjani

Classification of Goods & Services under GST, Customs & Other Indirect Tax Laws is a definitive, litigation-grade reference work devoted to one of the most technically complex and dispute-intensive areas of Indian indirect taxation—classification. Far from being a mere tariff or rate-selection exercise, classification lies at the heart of indirect tax compliance and controversy. It determines not only the applicable GST rate or customs duty, but also eligibility for exemptions, valuation linkages, input tax credit availability, import and export treatment, applicability of trade policy restrictions, preferential tariff benefits under FTAs, and ultimately, litigation outcomes. This book approaches classification as a structured legal discipline, governed by statutory rules, interpretative principles, administrative guidance, and judicial precedent. It integrates doctrinal clarity with practical applicability. This Edition reflects the maturity of post-GST classification jurisprudence while preserving continuity with principles developed under the erstwhile Central Excise, Service Tax, and Sales Tax regimes. What distinguishes this publication is its dual character. It functions simultaneously as:

• A conceptual rulebook, explaining how classification must be undertaken under GST and Customs, and
• A judicial classification compendium, showing how goods and services have been classified by courts, tribunals, and authorities over time, supported by circulars and notifications.

The result is a single, authoritative volume that supports decision-making, compliance, and defensible litigation strategy.

This book is designed for professionals and institutions for whom classification accuracy is critical and consequential, including:

• GST and Customs Practitioners handling advisory, audits, and disputes
• Chartered Accountants, Cost Accountants, and Indirect Tax Consultants
• Legal Professionals appearing before adjudicating authorities, tribunals, and courts
• Corporate Tax, Finance, and Supply-chain Teams dealing with rate disputes and classification risk
• Importers, Exporters, Manufacturers, and Service Providers
• Departmental Officers, Audit Teams, and Revenue Authorities
• Advanced Students and Researchers specialising in indirect tax law
