MUMBAI, Oct. 14 -- Authorities have seized 20 tonnes of Chinese firecrackers, valued at Rs.6.32 crore, smuggled into the Nhava Sheva Port at Navi Mumbai, after they were declared as "leggings". The consignment was seized by the Mumbai unit of the Directorate of Revenue Intelligence (DRI) on October 5. Examination of the suspicious consignment revealed around 60,000 pieces of firecrackers concealed behind a superficial layer of leggings, DRI officials said. The import of firecrackers is restricted under the Foreign Trade Policy and requires licences from the Directorate General of Foreign Trade and the Petroleum and Explosives Safety Organisation (PESO), under the Explosive Rules, 2008. In a separate operation code-named "Operation Fire Trail" in July, the DRI seized 100 tonnes of Chinese fireworks, valued at Rs.35 crore, from the Nhava Sheva and Mundra ports, and Kandla SEZ. The fireworks were concealed in seven containers, whose contents had been declared as mini-decorative plants, artificial flowers and plastic mats....
