An application for relief from the payment of duties imposed is to be filed with the District Director of Customs as defined in 19 CFR 1.1(d) if the following circumstances prevail:
(a) When an item covered by the entry is not within the class of items liable to duty (i.e., that the item does not constitute equipment, repair parts or materials within the meaning of section 466 of the Tariff Act of 1930);
(b) When the purchase of the equipment, repair parts or materials or the making of the repairs was necessitated by stress of weather and/or other casualty encountered during the regular course of the particular voyage and was necessary to secure the safety and seaworthiness of the vessel; or
(c) When the equipment, repair parts or materials were manufactured or produced in the United States and the labor involved was performed by residents of the United States or by members of the regular crew of the vessel.
To insure consideration in the liquidation (i.e., the assessment of duty) of the entry, the application for relief must be filed within 90 days from the date of the entry, except in meritorious cases, the District Director may grant an extension of 90 more days upon written request therefor.
