Summary

Convert foreign money into U.S. dollars for import duties using values the Treasury sets or the New York market rate. Coins are valued by the pure metal in the country’s standard coin. The Treasury must estimate and publish coin values on January 1, April 1, July 1, and October 1 each year. Normally you use the quarterly values the Treasury publishes for the quarter when the goods are exported. If no quarterly value exists, or the published value differs by 5 percent or more from the New York buying rate at noon on the export day, convert at either the noon buying rate that day or a rate based on the first buying rate the Federal Reserve Bank of New York certifies that quarter — but that certified rate can be used only if it is within 5 percent of the noon rate. The Federal Reserve Bank of New York decides and certifies the buying rate and may base it on recent transactions or quotations, or on actual bills-of-exchange or last known foreign transactions if no direct buying rate exists. Definitions — buying rate: the market buying rate in New York for cable transfers in that foreign currency. If banks are closed on the export day, use the noon buying rate from the last prior business day.
