Customs exemption updated to add Metaphenoxy Benzaldehyde to the notified schedule, changing tariff classification scope. The Central Government, invoking its power under the Customs Act and being satisfied of public interest, amends Notification No. 464/86-Customs by inserting a new Sl. No. 18 in the Schedule: Metaphenoxy Benzaldehyde, thereby adding that chemical to the notification's exemption list.
