CBP extends mandatory Entry Type 13 date for international mail to Jan. 20, 2027
CBP extended the compliance date for the new informal entry procedures for international mail from Oct. 22, 2026, to Jan. 20, 2027, a 90-day extension. Beginning Jan. 20, 2027, international postal shipments subject to Section 201, 232 or 301 duties, or within the jurisdiction of a Partner Government Agency, must be filed electronically in the Automated Commercial Environment through the new Entry Type 13 process for informal entry; otherwise formal entry is required. There are no changes to international mail entry procedures before that date, and CBP encourages filers to use the optional Entry Type 13 process during the transition.
