§ 834. Refusal of clearance to vessel refusing to accept freight
The Secretary of the Treasury is authorized to refuse a clearance to any vessel or other vehicle laden with merchandise destined for a foreign or domestic port whenever he shall have satisfactory reason to believe that the master, owner, or other officer of such vessel or other vehicle refuses or declines to accept or receive freight or cargo in good condition tendered for such port of destination or for some intermediate port of call, together with the proper freight or transportation charges therefor, by any citizen of the United States, unless the same is fully laden and has no space accommodations for the freight or cargo so tendered, due regard being had for the proper loading of such vessel or vehicle, or unless such freight or cargo consists of merchandise for which such vessel or vehicle is not adaptable.
