Tariff value fixation: substituted tariff tables maintain existing values for edible oils, metals and select agricultural commodities. The Central Board of Indirect Taxes & Customs has substituted Tables 1-3 of the principal Customs notification to fix tariff values for specified imports. The substituted tables set out tariff values in US dollars per metric tonne or per unit for categories including edible oils, brass scrap, poppy seeds, areca nut, and specify valuation units and product descriptions for gold and silver, noting where values remain unchanged and identifying applicable exclusions and publication history.
