Overview

One Submission,
Connected to Every Agency.

A single trade transaction may go through Customs, the FDA, quarantine, environment, and more. Single Window folds all of it into one gateway — no separate forms, no repeated entries, no agency visits. And when the rules change, officials reshape the system themselves.

Compliant with international standards (WCO, UN, WTO) and architected to extend toward future Global Single Window integration with neighboring nations. Originally launched as a core module of UNI-PASS, now also delivered as a standalone solution.
