Legal Landscapes of Tariffs and International Commerce
This panel is our foundation and introduction to tariffs through the voices of academics who specialize in the field. We will explore the legal frameworks that govern international commerce at the intersection of trade and the executive, judicial, and legislative branches. Panelists will analyze the interplay between World Trade Organization (WTO) rules, bilateral and multilateral treaties and commitments, recent court rulings, executive orders and proclamations, and the increasingly frequent use of unilateral tariffs.

Panel 2 (2:00 – 3:00 PM)
How Diverse Industries and Carriers Navigate the Global Market
From fashion to food, automobiles to electronics, tariffs are reshaping global supply chains, pricing strategies, and consumer access. Tariffs now directly affect everyday products from luxury handbags and shoes to imported foods, steel and aluminum, even pharmaceuticals and electronics.
This panel will bring together commodities importers and carriers to explore the commercial, legal, and consumer-facing consequences of the recent tariffs. Speakers will discuss how tariffs alter sourcing and manufacturing decisions, create compliance and enforcement challenges in-house and shift marketing and pricing strategies across different industries. By highlighting sectors affected in varying degrees, the conversation will underscore how tariffs ripple across the economy, shaping the decisions of carriers, commercial importers, and ultimately consumers.
