The decree also gives the state pre-emption rights for the materials that have been reported at a price "in line with their current market value".

Failure to comply with the reporting obligation may result in seizure of the construction materials and fines up to HUF 5 million.

The decree enters force on Friday.

Prime Minister Viktor Orbán revealed the steps to manage rising construction material prices a week earlier. He said curbs on exports of some building materials would be introduced from the fall after the measure is cleared in Brussels.
