The mineral industry of the British Empire and foreign countries : statistical summary (production, imports and exports) 1933-1935

Throughout the trade statistics in this document, materials imported or exported on government account have been included as far as possible. Trade statistics for the United Kingdom include the trade of Great Britain and Northern Ireland with the Irish Free State, and exclude the direct foreign trade of the Irish Free State, which is given separately. The trade of the Saar territory prior to February 18, 1935 is recorded with the trade of France, on and after that date it is recorded with the trade of Germany. Trade statistics for Japan do not include trade between that country and the rest of the Japanese Empire. Trade figures for Korea and Formosa include the trade with all other parts of the Japanese Empire. Except where otherwise stated the trade figures are intended to represent imports for home consumption and exports of domestic produce. In the case of foreign countries, however, many countries include a certain amount of "nationalised" goods, i.e. goods originally imported, but which, if dutiable, have been charged with duty and subsequently reexported. Goods imported for "improvement" and re-exported after "improvement" are also generally included. Import statistics for the United States refer to imports entering the country for immediate consumption plus withdrawals from bonded warehouse (some of which may afterwards be re-exported). The units of quantity adopted are the cwt." of 112 lb. (avdp.} ; ton of 2,240 lb. (avdp.}; imperial gallon and metric carat. For precious metals the troy ounce of 480 grains is used. Further particulars relating to the various minerals and metals referred to in this summary will be found in the brochures published by the Mineral Resources Department of the Imperial Institute (see lists on cover). These brochures contain much information which has a bearing on the statistical data recorded in this volume.
