Partial exemption from auxiliary customs duty limits payable duty to five percent ad valorem on specified exempt goods. Exemption limits auxiliary customs duty on goods already partially or wholly exempt from basic customs duty so that only the portion up to 5% ad valorem of value (as determined under section 14 of the Customs Act) is chargeable; any auxiliary duty in excess of that 5% is exempted. The exemption applies only to goods listed in the Schedule of antecedent customs notifications and remains subject to the conditions attached to those original notifications. The measure is issued under section 25 of the Customs Act read with section 111(4) of the Finance Act, 1992.
