More than 83,000 items were confiscated by the Border Force at airports in one operation over six days in December.
The haul of counterfeits included Harry Potter wands, "Louis Vuitton" handbags and "Nike Air Max" trainers.
In recent weeks, Â£1m worth of goods had been stopped at the border of UK ports and hubs.
The government published the figures to warn consumers on the hunt for last-minute Christmas presents to check they were buying legitimate gifts.

Immigration Minister Robert Goodwill said: "The international trade in counterfeit goods undercuts honest traders, and is linked to serious and organised crime, sweatshop working practices, child labour, and even the funding of terrorism.
"Unsuspecting customers are also left out of pocket with inferior and potentially dangerous goods.
"We are determined to crack down on this criminality and Border Force officers help protect consumers by working around the clock at ports, airports and mail sorting centres identifying and seizing counterfeit goods."
Once seized, the force's specialist international trade team contacts the brands to discover if the goods are fake or genuine, and if they are the former, the items are destroyed.
It is then up to each brand to decide if they want to prosecute those trying to import them.
Matthew Cope, from the Intellectual Property Office, said its operations had intensified in the build up to Christmas.
"We have detained goods destined for shops and markets, proving the worth of the co-ordinated approach," he added. "It is important that we have a united response and that people are protected from this type of crime.
"Anyone looking for a bargain this Christmas should be wary of prices which look too good to be true, from cut price alcohol to heavily discounted electronics, and report anything suspicious."

Revenues for the year to the end of March rose to $46.3bn, with the firm's mobile phone business contributing some $9.14bn of the total.
Its revenues have been helped by the purchase of Motorola in 2014, which has made it the world's third-largest smartphone maker.
However, net profits grew by just 1% to $829m, missing expectations.
Lenovo bought Motorola and IBM's low-end server unit last year in an attempt to diversify beyond the PC business.
The firm said it had been "another record year for Lenovo with a more diversified business", but put its poor net profit result down to increased operating expenses.
Lenovo said its mobile business, including Motorola, had "delivered record shipments and built a more globally balanced business".
The Beijing-based giant also said its market share in the global personal computer sector had grown to a record high of 20.9%.
