explanatory notes
coverage: Except where otherwise stated all the statistics
shown relate to the United Kingdom of Great Britain and
Northern Ireland.
The Channel Islands and the Isle of Man are also included
in the ‘United Kingdom’ overseas trade statistics, but are
excluded from the production statistics. The UK part of the
Continental Shelf is included in both the overseas trade and
the production statistics.
All figures for the latest year shown are provisional and
subject to revision.
rounding of figures: In tables where figures have been
rounded to the nearest final digit, there may be a slight
discrepancy between the sums of the constituent items and
the total as shown.
units: The statistics in this volume are expressed in metric
units. The following factors are given for converting from or
into non-metric units:
Troy ounce Kilogram
1 = 0.0311035

apparent consumption: BGS estimates of apparent
consumption of metals are based on the formula: production
(primary and secondary) plus imports minus exports. All
the main traded forms of the metal are taken into account,
for example, ores, concentrates, intermediate products,
unwrought metal and alloys, oxides, etc. Figures are given
in terms of metal content. No information is available for
stock changes. Such estimates of apparent consumption are
made for metals for which there are no reported consumption
statistics: in this edition data are given for chromium, cobalt,
manganese, molybdenum, titanium and zirconium.
trade: Trade figures from INTRASTAT, the new system for
measuring intra-EC trade became available from 1993. This
was introduced following the abolition of customs controls
as a result of the Single Market and trade figures are now
compiled from data provided directly from companies instead
of Customs documents. Extra-EC trade continues to be
collected from Customs declarations as before. The transition
from one system to another has produced some anomalous
figures in terms of the size of the trade in and unit value of
certain commodities. These factors should be taken into
consideration when evaluating trends. Figures given in this
edition are the combined intra and extra-EC trade data.
Values of commodities are cif for imports and fob for
exports.
The terms ‘scrap’, ‘unwrought’ and ‘wrought’ metal include
alloys unless these are separately shown.
