As online and mail order sales rose by more than 1,000 billion forints last year, so did the number of breaches of rules, Keszthelyi said.

As a result, 750 webshops were scrutinised in addition to the 600-800 that are routinely checked, she added.

The number of physical product safety checks of imported goods at customs points rose to 27 million last year from 22,000 in 2017.

Heightened scrutiny has reduced the rate for violations from half to 15-20%, Keszthelyi said.

She added that over the past five years, the range of fines for violations has risen from 15,000-500,000 to 200,000-2,000,000 forints.
