Short answer

The Tanzania Electronic Single Window System (TeSWS) is the platform Tanzania reports to the WTO under its single window commitment. Tanzania first notified that phase one was complete and running at pilot level ¹. A later WTO record says phase two is complete, phase three is in its final stage, 40 regulatory authorities are onboarded and 877 of 1,268 clearing agents are registered ². The agreed date for full implementation is 30 December 2028 ².

How TeSWS relates to other systems

TANCIS remains the customs declaration system. TRA said in January 2025 that the enhanced TANCIS links with 36 institutional systems ⁴. Port charges are billed through the TPA Electronic Payment Portal (TePP) ⁵. The TRA home page links a portal labelled TANESW ⁶.

Zanzibar is building its own single window. TRA reported on 2 June 2026 that the Korea Customs Service supports the project ³. That system is at the announced stage in the source.

The CAG information systems report for FY 2024/25 found that the Tanzania Bureau of Standards application system is not integrated with TANCIS ⁷.
