Shipping notice: truck drivers' strike in Italy
Updated 19/10/2026
Since 16 October, truck drivers protesting against high diesel prices have been blocking roads and ports in Southern Italy (Campania, Calabria, Sicily, Puglia, Basilicata), and the protest could spread to the rest of the country. The strike affects all our shipments, in Italy and abroad: Poste Italiane is currently not collecting parcels, while BRT and DHL are collecting as usual but deliveries may be delayed in some areas.
- Italy we ship with BRT and DHL · possible delivery delays
- European Union for now we ship with DHL only · possible delays
- Non-EU countries (customs) shipments temporarily suspended: they will leave as soon as Poste Italiane resumes collections
We apologise for any inconvenience and thank you for your patience.
