• In USA :

As agreed in the  Trade Facilitation and Trade Enforcement Act of 2015, signed by President Barack Obama Feb. 24, U.S. Customs and Border Protection (CBP) announced that March 10, it raised the value of a shipment of merchandise imported by one person on one day that generally may be imported free of duties and taxes from $200 to $800. This raising of the de minimis exemption is due to an amendment of the Tariff Act of 1930 included in the Trade Facilitation and Trade Enforcement Act of 2015. 

Shipments with a value of $ 800 or less for the de minimis exemption will be eligible under the same processes and the same restrictions that currently apply to shipments of de minimis $ 200 or less.

Shipments valued at $800 or less for the de minimis exemption will be eligible under the same processes and with the same restrictions that currently apply to de minimis shipments of $200 or less.

In other words, there are no specific customs procedures or duties or taxes to pay if the value of the shipment is less than or equal to 800 USD (Package value = value of goods + shipping costs + insurance costs).
