Mr MacSwiney added that one commercial body that liaises with HMRC on customs had developed an alternative system and presented it to the Border Delivery Group in 2018.
“That system can deliver what HMRC needs but they appear to be unwilling to accept a commercial solution,” he said.
Rod McKenzie, chief executive of the Road Haulage Association, described the draft text as “incomprehensible pie-in-the-sky” thinking.
“I could’ve written it three years ago,” he said. “The Cabinet Office is cagey. We can’t get useful information out of them.
“It’s a shambles because they’re hoping there will be a free trade agreement but ‘last minute’ won’t work. There are 10,000 trucks arriving at Dover a day.
“We need to know what the customs procedure will be, that people are capable of inputting the data, that people have been recruited and trained to process the data and that the IT system is built and tested.”
A Government spokesman said it will publish a model for new border operations next month. “We are continuing our preparations for the end of the transition period and the introduction of new border controls, including by providing £84m to grow the customs intermediary sector to encompass EU trade after 2020.
“We are regularly engaging with industry as plans develop, in particular with regard to a new IT system.”
