The Central Board of Indirect Taxes and Customs (CBIC) has approved a new Special Notified Zone (SNZ) at the Surat Diamond Bourse (SDB) to facilitate rough diamond trading. This designation allows eligible buyers and sellers to trade rough diamonds under simplified customs procedures within a bonded zone framework. The move aims to position Surat as a global diamond trading hub, reducing India's dependence on Antwerp and Dubai as intermediary markets for rough diamond sourcing.

A Special Notified Zone (SNZ) is a customs-designated area where specific goods — typically high-value commodities — can be traded under deferred or simplified duty structures without immediate clearance into the domestic tariff area. The SNZ concept is governed under India's Customs Act and is operationally supervised by CBIC.

The Surat Diamond Bourse, inaugurated in December 2023 and touted as the world's largest office complex, was built precisely to consolidate India's diamond processing and trading ecosystem. However, without SNZ status, rough diamond imports still faced complex customs procedures that discouraged international traders from conducting primary rough diamond sales in India — they preferred Antwerp (Belgium) or Dubai.

By creating an SNZ within SDB, CBIC enables foreign rough diamond sellers (including mining companies from Russia, Botswana, Canada, and Australia) to display, auction, and sell rough stones to Indian buyers without the stones technically 'entering' Indian customs territory until a buyer decides to import. This is functionally similar to how bonded warehouses or Free Trade Warehousing Zones (FTWZs) operate — goods remain in a suspended customs state.

For India, this is strategically significant: India polishes over 90% of the world's diamonds by volume. Yet rough diamond price discovery and primary trading happened abroad, giving intermediaries a margin. The SNZ directly addresses this value-chain gap. From an exam perspective, this connects to topics like SEZs, FTWZs, Customs Act provisions, export promotion policy, and CBIC's regulatory authority over indirect taxation infrastructure.
