Customs tariff amendment: Camphor reclassified with maximum protective duty under the revised schedule to the Customs Tariff Act. The Customs Tariff Act First Schedule is amended by omitting the existing Camphor entry at sub heading (10) of Heading 29.01/45 and inserting a new sub heading after (20) that lists Camphor with a 100% rate of duty under the protective tariff column, with preferential area and standard fields left blank.
