Source: International Convention on Tonnage Measurement of Ships. Section (U.S. Code) 46 App. U.S.C. 81.
Section 14306(a) requires that the Secretary accept the measurement and certificate of a vessel of a foreign country as evidence of compliance with this chapter when the Secretary finds that the laws and regulations of that foreign country that are related to measurement are similar to those of this chapter, or that that country is a party to the Convention.
Section 14306(b) provides that the Secretary does not have to accept the measurement and certificate of a vessel of a country that does not recognize United States measurements. It also authorizes the Secretary to apply appropriate measurement standards to such foreign vessels, subject to international agreements to which the United States is a party.
