The Secretary of the Treasury shall deliver to the Commission, upon its request, samples of hazardous substances which are being imported or offered for import into the United States, giving notice thereof to the owner or consignee, who may appear before the Commission and have the right to introduce testimony. If it appears from the examination of such samples or otherwise that such hazardous substance is a misbranded hazardous substance or banned hazardous substance or in violation of section 1263(f) of this title, then such hazardous substance shall be refused admission, except as provided in subsection (b) of this section. The Secretary of the Treasury shall cause the destruction of any such hazardous substance refused admission unless such hazardous substance is exported, under regulations prescribed by the Secretary of the Treasury, within ninety days of the date of notice of such refusal or within such additional time as may be permitted pursuant to such regulations.
Pending decision as to the admission of a hazardous substance being imported or offered for import, the Secretary of the Treasury may authorize delivery of such hazardous substance to the owner or consignee upon the execution by him of a good and sufficient bond providing for the payment of such liquidated damages in the event of default as may be required pursuant to regulations of the Secretary of the Treasury. If it appears to the Commission that the hazardous substance can, by relabeling or other action, be brought into compliance with this chapter, final determination as to admission of such hazardous substance may be deferred and, upon filing of timely written application by the owner or consignee and the execution by him of a bond as provided in the preceding provisions of this subsection, the Commission may, in accordance with regulations, authorize the applicant to perform such relabeling or other action specified in such authorization (including destruction or export of rejected hazardous substances or portions thereof, as may be specified in the Commission's authorization). All such relabeling or other action pursuant to such authorization shall, in accordance with regulations, be under the supervision of an officer or employee of the Commission designated by the Commission, or an officer or employee of the Department of the Treasury designated by the Secretary of the Treasury.
All expenses (including travel, per diem, or subsistence, and salaries of officers or employees of the United States) in connection with the destruction provided for in subsection (a) of this section and the supervision of the relabeling or other action authorized under the provisions of subsection (b) of this section, the amount of such expenses to be determined in accordance with regulations, and all expenses in connection with the storage, cartage, or labor with respect to any hazardous substance refused admission under subsection (a) of this section, shall be paid by the owner or consignee and, in default of such payment, shall constitute a lien against any future importations made by such owner or consignee.
