DHL Express is suspending deliveries to the US worth more than $800 (£603) because of a "significant increase" in red tape at customs following the introduction of Donald Trump's new tariff regime.
The delivery giant said it will temporarily stop shipments from companies in all countries to American consumers on Monday "until further notice".
It added that business-to-business shipments will still go ahead, "though they may also face delays".
DHL's actions may not effect too many sellers, the reported increase in customs red tape may have a wider effect and probably impact on delivery times in the US.
