International Mail: Progress Made in Using Electronic Data to Detect Illegal Opioid Shipments, but Additional Steps Remain [open pdf - 3MB]
From the Document: "According to the National Institute on Drug Abuse, more than 130 people die every day in the United States after overdosing on opioids. Since illegal opioids can arrive through international mail shipments, Congress has called upon the U.S. Postal Service (USPS), U.S. Customs and Border Protection (CBP), and U.S. Department of State (State) to collaboratively improve the nation's ability to detect and interdict such shipments. The Synthetics Trafficking and Overdose Prevention Act of 2018 (STOP Act of 2018) requires USPS to transmit to CBP certain percentages of the advance electronic data (AED) on international mail shipments it receives. USPS collects these data from foreign postal operators. [...] This report examines: (1) the extent to which USPS has transmitted required AED for international mail shipments to CBP for use in targeting mail for inspection; (2) any steps USPS and CBP have taken to assess or improve the quality of AED that USPS transmits to CBP; (3) what is known about the costs and benefits of using AED for targeting purposes; and (4) the extent to which USPS has presented targeted international mail to CBP for inspection."
