MPs have warned that new border inspections could cause delays later this year if the government does not act quickly.
The Public Accounts Committee warned of potential disruption as passenger loads normalized.
“If more isn’t done soon,” Logistics UK agreed with the committee’s findings.
So far, the administration claims minimal border interruption.
A government spokesperson said it continued to encourage firms to trade effectively with Europe and capture new opportunities.
But Public Accounts Select Committee Chair Meg Hillier said the government should undertake “far more work” to ensure the border worked successfully and to reduce the existing burden on firms trade with the EU.
Logistics UK urged the government to “act now” to enable the smooth implementation of new post-Brexit border restrictions, including inspections on agricultural and food imports, and biometric checks on EU travellers.
“We’re running out of time,” said Sarah Laouadi, a trade association policy director. Firms need to know which ports will process their products after July 1, she said.
“Of course, you need advance warning,” Ms. Laouadi added.
She warned that without it, lineups at UK ports might reach 29 miles long by summer.
