Carrier's form of shipping receipt can be obtained free of charge on application. Shipper not using Carrier's form must furnish, in writing, and tender with the goods, name of vessel for which shipment is intended, date of sailing, port of discharge, correct description of cargo, marks, numbers, gross weight of each package and for whose account cargo is delivered. Attention is especially directed to Section 10(a), Shipping Act, of 1984, which provided in part: "That it shall be unlawful for any person (which includes individuals, Corporations, Partnerships, and Associations existing under or authorized by the laws of the United States or a foreign country), to knowingly and willfully, directly or indirectly, by means of false billing, false classification, false weighing, false report of weight, false measurement, or by any other unjust or unfair device or means obtain or attempt to obtain ocean transportation for property at less than the rate or charges that would otherwise be applicable.
