From risk to resilience: the transition to SAP GTS E4H 2023 and Passar

In today’s dynamic and data-driven international trade landscape, Global Trade Management solutions (GTMs) are indispensable for businesses navigating challenges such as geopolitical uncertainty, protectionism, evolving regulations (e.g. ESG), supply chain disruptions and emerging technologies. These GTMs cover various regulatory areas, including electronic customs declarations, Free Trade Agreements (FTAs), sanctions and export controls, and offer a multitude of benefits such as trade compliance, automation, collaboration, data visibility and governance.

Nevertheless, the task of identifying the right GTM solution(s), devising an implementation roadmap and budgeting for the necessary efforts can be challenging.

SAP’s premier trade solution, SAP Global Trade Services (SAP GTS), stands out as one of the market’s leading GTM products, offering extensive functionality and global coverage. Existing SAP GTS users need to switch to SAP GTS Edition for HANA (SAP GTS E4H 2023), ideally before the end of 2025 (coinciding with the end of maintenance for SAP GTS 11). Additionally, they must decide whether to opt for an on-premise or cloud-based implementation of SAP GTS E4H 2023.

Furthermore, the Swiss customs authorities are set to retire their current e-dec customs declaration system by mid-2025, replacing it with Passar. Passar is designed to interface with NCTS Phase 5/6 and will include the referencing of transport information with customs declarations. This transition makes it necessary for customers to upgrade to Seeburger BIS 6.7, available in both on-premise and cloud-based versions. The shift to Passar 1.0  (NCTS 5 and export) is already under way, with Passar 2.0 (import) slated to launch at the start of 2025. It is also important to note that some EU national customs systems are also either undergoing or are scheduled for changes. For SAP’s planning related to GTS solutions in this context, you can find information at Notification of Legal Changes.

In this evolving trade environment, staying informed and prepared is crucial for businesses engaged in international trade operations.


The numerous constraints and tight deadlines present a challenge for companies and their imperative to maintain the seamless flow of goods across international borders. Based on our interactions with SAP and Swiss customs, it appears unlikely that these deadlines will be extended. It is also important to acknowledge that making critical system migration decisions based solely on speculative extensions involves a significant degree of risk.

With this in mind, PwC and SAP offer the following recommendations to Swiss-based SAP GTS customers:
