All these buyback offers are now being closely examined by officials (see box). On an average, a TV company charges about Rs 10,000 for its product, provided the customer brings his old set in working condition. Since the old TV has a price, the manufacturer, says a Finance Ministry official, ends up making Rs 10,000, in addition to the amount he sells the old set for. And since since the new TV is being sold for Rs 10,000 (against the normal price of around Rs 20,000), the value of the goods may have been underdeclared to excise authorities. Delhi Customs authorities have already served a showcause notice of Rs 43 crore on Sony. The allegation: Sony was importing not components, but completely knocked down (CKD) kits which were later assembled for sale. A company can import CKD kits for assembly and sale, but it has to pay a higher rate of duty, the same as it would pay for a product if it were imported as a whole. Delhi Customs claims Sony imported CKD kits and paid duty for components.
