Schedule D code 4952 and CBPโs port code list
4952 is how the Census Bureauโs trade-statistics edition of Schedule D numbers St. Thomas VI Border Patrol. CBPโs current list of valid ACE port codes (Appendix E, revised 2026-02-03) does not include 4952. Confirm the port code for your entry with your licensed customs broker before filing.

The first two digits are the customs district: 4952 belongs to San Juan, PR (district 49), and every port of entry in that district starts with the same two digits.
The code is for customs, not carriers. Carriers, forwarders and NVOCCs book and manifest against the UN/LOCODE for the place, and the bill of lading shows that five-character code, not the Schedule D code. Many Schedule D ports of entry โ airports, land border crossings, user-fee airports and inland ports โ have no UN/LOCODE seaport entry at all, and this site does not hold a UN/LOCODE page for St. Thomas VI Border Patrol; the UN/LOCODE finder searches the full code list.
