Dear Lord Weir of Ballyholme,

As National Statistician and Chief Executive of the UK Statistics Authority, I am responding to your Parliamentary Question asking what assessment has been made of the financial quantity of trade for businesses dealing with chemical products between Northern Ireland and Great Britain (HL4282).

The Office for National Statistics (ONS) has published interregional trade in goods and services between UK regions at the International Territorial Level 1 (ITL1) geography, by grouped industry for the years 2019 and 2020[1]. The ONS do not currently publish interregional trade estimates for the chemical manufacturing industry, however this industry is estimated as part of the manufacturing industry interregional trade estimates. The manufacturing industry may not capture all businesses dealing with chemical products as industry allocation is based on the main activity of the business and so there will be businesses not in the manufacturing industry that purchase or sell chemical products.

The Northern Ireland Statistics and Research Agency (NISRA) also publish exports and imports between Northern Ireland and Great Britain between businesses in the manufacturing industry[2]. Variations between the ONS’s and NISRA’s estimates are due to methodological differences.

The ONS data on interregional trade within the manufacturing industry between Northern Ireland and Great Britain can be found in Table 1. NISRA data on trade within the manufacturing industry between Northern Ireland and Great Britain can be found in Table 2.

Yours sincerely,

Professor Sir Ian Diamond
