International Mail
Most items can be mailed to foreign countries. However, there are certain restrictions. It is important that mailers contact Mail Services to determine the proper classification and documentation required.
If customs regulations are not followed and documentation is not exact, the item will be impounded by customs until the addressee makes arrangements for clearance and the payment of whatever duties required for the release of the item. Custom rules apply the same whether mail is sent by USPS or other couriers.
For letter size items, use the special Tyvek Red/Blue border envelopes. They will enhance service and help mail service separate them from Domestic mail.
NOTE: The last line of any foreign address should be the country name spelled out in capital letters, in English.
