The UK government has repeatedly changed and  deferred its plans for the introduction of full import controls following the  UK's exit from the European Union (EU). Brexit caused significant changes to  how goods and services are traded between the two territories.
However, it is almost three and a half years since  the transition period ended and the UK's government has still not specified  when it intends to have a full regime in place. Here we take a look at the  changes and what they mean for UK businesses.
Voiced concerns
The government is currently operating a partial import  control regime after delaying the implementation of full controls five times. It  also estimates that it will have spent at least £4.7 billion to implement new  arrangements and improve the management of the border but this does not take  into account the costs and disruption to business.
The British Chambers of Commerce (BCC) has repeatedly voiced  its concerns over the customs checks  and charges that come into force at the end of April. 
The second phase of  the UK's Border Target Operating Model introduced charges of up to £145 for  imports of plant and animal products. It was the first time for decades  that firms needed to pay such fees for EU imports of goods arriving in Great  Britain.
Government figures  show the UK imports just under 30% of all the food it consumes from the  EU. 
Costs and clarity
William Bain, Head  of Trade Policy at the BCC, says: 'Firms face mounting confusion and  uncertainty about exactly how and when the borders checks and costs will be  fully implemented. It is crucial for business and trade that the government  gives clarity on what is happening.  
'While the government  did consult on the new charges being introduced it chose not to listen. The  size of these costs shows scant regard to the interests of either businesses or  consumers.'
SME  exporters in the doldrums
Brexit, combined with the pandemic, have left most SME exporters struggling to boost sales  in the first quarter of 2024, according to research conducted by the  BCC.
Almost a quarter of  SME exporters saw sales decrease during this period while over half saw no  change, the BCC's data shows.
More than half of  all SME exporters (53%) saw no change in overseas sales, and 23% reported a  decrease.?? 
The BCC says the  proportion of businesses reporting decreased overseas sales began to rise in  the run up to Brexit and has remained stubbornly higher ever since.???? 
Fix the barriers
Bain adds: 'Business  needs to work with government to put in place a framework that makes use of all  the advantages the UK has, to keep us at the top table, and to access  incentives for our exports overseas.?? 
'We must also look  again at fixing some of the growing trade barriers with the EU. It is still our  biggest trading partner, but firms continue to express huge frustration with  the complexity and costs involved.'
Repeated delays
The costs and  inconveniences to businesses of the government's repeated delays were laid bare  in a recent National Audit Office report.
It said that late announcements  about policy and uncertainty about the implementation of controls have also  reduced the ability of businesses and ports to prepare for changes.
According to the  NAO, although post EU exit border processes have operated relatively smoothly,  businesses trading goods between the UK and the EU have faced additional costs  and administrative burdens.
New controls are  set to be introduced this year relating to sanitary and phytosanitary (SPS)  goods and safety and security declarations. When fully implemented, these  controls will cost traders an estimated £469 million a year, according to the  NAO.
The report also  warned that loss of access to EU surveillance and alert systems reduces the  UK's awareness of impending dangers like African Swine Fever.
Realistic  approach
Gareth Davies, Head  of the NAO, says: 'The UK leaving the EU created a large-scale change in  arrangements for the movement of goods across the border. However, more than  three years after the end of the transition period, it is still not clear when  full controls will be in place.
'The border  strategy has ambitious plans to use technology and data to facilitate trade  while managing risks. To achieve its objectives, government requires strong  delivery and accountability – including a more realistic approach to digital  transformation – together with effective monitoring to enable future  improvements.'
