US customs: recent legal developments and practical updates

Legal requirements form the foundation of our customs and trade compliance work. Understanding how laws are made, how they are structured in terms of hierarchy, how they interact, how their provisions are interpreted, and how they evolve over time is indispensable knowledge for every customs and trade compliance practitioner.
In our previous sessions, we covered how EU laws and UK laws are made. This session invites you to focus on US customs law. We will cover the following topics:
- How US customs laws are made and how to navigate them, including practical tips
- The latest customs developments
- Current challenges for EU and UK exporters and importers

About customs roundtables
Customs is a complex area and it’s difficult to stay up to date with all the latest developments.
Customs roundtables are designed for the customs community to come together and exchange views regarding various areas of customs. This can be either specific cases and questions or wider industry trends. The discussions will go into technical details and will allow participants to learn from peers and exchange views and experiences. It’s an excellent opportunity to have an open discussion on some of the most pressing customs issues. We aim to create an open and supportive live forum that also offers the facility to continue discussions online.
We welcome customs experts and experts-to-be in all areas of customs (origin, valuation, special procedures etc) and from all backgrounds (legal, in-house, academic, consulting etc).
