The price of Singapore kerosene-type jet fuel during the two month period of April and May 2015 averaged US$74.76 per barrel, which accounted for 8,979 yen in the average exchange rate of 120.10 JPY/USD during the same period.
As a result, with reference to the fuel surcharge benchmark list for FY2015 in Japanese yen, this corresponds to Zone C of fuel surcharges.
For sale outside of Japan, YQ will be set to zone B.
