# CBP Extends Entry Type 13 Deadline

U.S. Customs and Border Protection (CBP) extended the mandatory implementation date for Entry Type 13 electronic informal entries for specified international postal shipments from October 22, 2026, to January 20, 2027. During the transition, importers, customs brokers, and logistics providers can use the process voluntarily while updating their filing workflows and systems. CBP has also proposed broader requirements for most international mail packages; those requirements are proposed, not yet mandatory.

- Importers, brokers, and logistics providers now have until **January 20, 2027** to implement the mandatory Entry Type 13 process for the specified shipments.
- Organizations can use the transition period to test electronic filing procedures and adjust operational processes; CBP encourages voluntary use before the new implementation date.
- Providers serving international postal shipments should distinguish the current Entry Type 13 mandate from CBP’s proposed broader requirements, which are not described as final in the signal.
