Postal services around the world are pausing deliveries to the US over confusion around new import taxes that must be paid on parcels from the end of the month, BBC reported.

US President Donald Trump signed an executive order last month ending the global import tax exemption on low-value parcels, which takes effect from 29 August.

While gifts worth less than $100 will remain duty-free, the changes mean all other packages will face the same tariff rate as other goods from their country of origin.

Postal services, including Royal Mail and Germany's DHL, said they would suspend deliveries until they had proper systems in place to deal with the new rules, according to BBC.
