Where the data comes from
Every figure is shown with its source and date. The RMB central parity rate is published by the China Foreign Exchange Trade System, authorised by the People’s Bank of China, and one of us enters it by hand each business day; export tax refund rates come from the State Taxation Administration’s refund-rate library.
This site is not an official channel. Results are for reference only; the official publication prevails. Disclaimer
