The US de minimus was abruptly removed about 1.5 months ago. After August 26, US consumers making small international orders of less than US$800 would have to pay tariffs otherwise known as an import sales taxes.
To say it has been a chaotic time for all is putting it mildly. There was no tariff collection program readily in place on the US border. So postal systems in dozens of countries around the world were forced to suspend shipments for some time. I also halted shipments to the US to avoid the initial problems at the border.
