Safe harbour definitions for raw diamond sales clarify eligible assessee, eligible business, gross receipts, and raw diamond criteria. Definitions are prescribed for the safe harbour regime relating to income from sale of raw diamonds taxable as profits and gains of business or profession. The rule defines the eligible assessee, eligible business, gross receipts, relevant previous year, and raw diamonds for the purposes of the safe harbour option. Raw diamonds must be uncut, unpolished, unassorted, unworked or simply sawn, cleaved or bruted, not conflict diamonds, accompanied by a Kimberley Process Certificate, and covered by Tariff Heading 7102.
