(a) In general. In an antidumping proceeding, the Secretary will convert foreign currencies into United States dollars using the rate of exchange on the date of sale of the subject merchandise.

If the Secretary establishes that a currency transaction on forward markets is directly linked to an export sale under consideration, the Secretary will use the exchange rate specified with respect to such foreign currency in the forward sale agreement to convert the foreign currency.

(c) Exchange rate fluctuations. The Secretary will ignore fluctuations in exchange rates.

(d) Sustained movement in foreign currency value. In an antidumping investigation, if there is a sustained movement increasing the value of the foreign currency relative to the United States dollar, the Secretary will allow exporters 60 days to adjust their prices to reflect such sustained movement.
