Dear Reader,

Recent months have once again demonstrated how swiftly the global customs and trade sector can change. Regulatory updates, tariff adjustments, new trade frameworks and sanctions measures are transforming the way businesses operate internationally. These developments highlight the growing interconnection between trade policy, environmental regulation and security concerns, as well as the need for customs practitioners to be agile, informed and proactive.

In this issue, we explore how evolving policies translate into practical challenges. Our Topic spotlight section opens with an in-depth explanation of how EU regulations are made, offering readers a clear understanding of the EU's decision-making framework. With environmental policy fast becoming a central part of customs compliance and carbon-related measures set to redefine trade operations in the coming years, we recommend reading two articles on CBAM updates: one on the critical deadlines approaching in the EU in 2026 and another on the steps importers must take now to ensure readiness in the UK by 2027.

Our contributors also explore the export of fine art and cultural goods to the European Union, shedding light on an area that is often overlooked until issues arise at the border. Meanwhile, the article on post-import price adjustments and transfer pricing navigates the complex relationship between customs valuation and international tax principles, drawing comparisons between the approaches of the US, the WCO and the EU.

The review of the EU’s revised Common Position on military goods and the discussion of customs law in international trade contracts highlight the direct impact of legal and policy shifts on daily practice.

In the Case law section, the tribunal's decision in Roseline Logistics v HMRC serves as a cautionary reminder of the importance of diligence, thorough documentation and clear contractual allocation of responsibility in the role of customs agents.

As usual, the News update section compiles recent developments across the EU, UK, US and Ukraine. In today's world, staying informed is crucial for ensuring compliance and anticipating enforcement trends.

Our Perspective section is no less forward-looking, offering analysis on AI and the future of customs tariff classification. As automation becomes more prevalent and data-driven tools transform decision-making processes, artificial intelligence is emerging as a valuable asset for customs authorities and traders.

I hope this issue will help you navigate the ongoing changes in customs and trade.
