Supply of Ship Stores [Section 89]:

Section 89 of the Customs Act covers the case of indigenous goods, which are supplied to a vessel as ship stores. It states that goods produced or manufactured in India and required as stores on any foreign going vessel or aircraft may be exported free of duty in such quantities as the proper officer may determine having regard to the size of the vessel or aircraft, the number of passengers and the crew and the length of the voyage or journey on which the vessel or aircraft is about to depart. In a nutshell, the duty free supply of shipstores, should be reasonable and not in commercial quantities.
