The Statistics and Registration Service Act 2007 gives the UKSA a statutory power to assess sets of statistics against the Code of Practice for Official Statistics.
Assessment determines whether it is appropriate for the statistics to be designated as National Statistics. Designation as National Statistics means that the statistics comply with the Code of Practice.
The latest assessment report confirmed the designation of Trade Statistics & Customs Analysis National Statistics products. National Statistics products are regularly assessed, for which the UKSA publishes a Programme of Assessment for scheduled reviews.
