International mail is subject to export controls and customs regulations. It is imperative that all individuals who send international UCI business related mail understand and abide by the following:

U.S. Export Controls

All UCI business-related international shipping export control information is maintained and updated by the UCI Office of Research Export Controls. To determine whether an export license is required, submit a shipment review form through the Office of Research's International Shipping website.

Exporting controlled materials, items, or technology to a foreign country or providing access to export controlled technology in the United States to an unauthorized foreign person, could result in severe criminal or civil penalties for the university and the university employee involved in the export. Prosecution of an export violation may result in fines of up to $1M and/or a prison sentence of up to 20 years.

Addressing Standards

  • Last line is country name only, in all capital letters
  • No abbreviations
  • Addresses written in Russian, Greek, Arabic, Hebrew, Cyrillic, Japanese, or Chinese characters must also bear the English translation of the names of the post office and country of destination.
