Postal services across Europe have suspended most parcel shipments to the US, citing widespread uncertainty about the impact of new import tariffs announced by Donald Trump.

France’s La Poste on Monday joined other operators, including Germany’s Deutsche Post, Spain’s Correos, Poste Italiane and the Belgian, Swedish and Danish postal services, which all halted a majority of US-bound shipments over the weekend.

Austria’s Österreichische Post and the UK’s Royal Mail said they would stop accepting packages on Tuesday, to allow enough time for packages posted before then to arrive in the US before the tariffs, scheduled to come into force at the end of August, kick in.
