STOP Act 2.0

STOP Act 2.0 would strengthen federal control over illicit activity in international mail and tighten how countries are included in the 100 percent advance information requirement. Key changes include a new criminal penalty for misrepresenting the country of origin of international mail shipments, a sunset provision that terminates the ability to exclude countries from the 100 percent information rule five years after enactment (eventually moving toward universal coverage), expanded annual reporting to Congress on compliance and data quality, and new authorities to pursue public-private partnerships and international information sharing focused on detecting fentanyl and other illegal substances. The bill also requires training for customs officers and a formal evaluation by the Comptroller General of the STOP Act of 2018 within a year of enactment. Overall, the bill aims to deter mail-based drug trafficking, increase transparency, and accelerate adoption of technology to trace parcel origins.
