Excise exemption for pigments and synthetic organic dyes allows nil-duty first clearances subject to annual aggregate value and eligibility conditions. Exemption grants nil excise duty on first clearances for home consumption of pigments and synthetic organic dyes within specified tariff sub-headings, subject to an annual aggregate value ceiling and exclusion where a manufacturer's or factory's aggregate clearances of all excisable goods in the preceding year exceeded that ceiling. Manufacturers or factories that did not clear the goods in the preceding year, or began clearing after the specified date, may claim the exemption upon filing a declaration and provided actual annual clearances remain within the ceiling; valuation follows the statutory formula and certain other whole-duty exemptions are excluded from the aggregate calculation.
