Global Readiness Backed by U.S. Strength

As the largest U.S. only full-service law firm we have built our international capabilities around two foundational principles.

First, due to our cross-border experience and our deep knowledge of the entire U.S. legal market grounded in 25 offices across every region of the country, we are a go-to choice for clients with in-bound investment and for international law firms needing a U.S. partner.

Secondly, when our clients need counsel outside the U.S., our global relationships with many of the finest firms in the world ensure that our clients can form relationships with the right lawyers in the right places rather than having to pick between a limited number of lawyers employed across a smattering of countries.

Polsinelli’s Foreign Desk Leaders are responsible for maintaining relationships with partner firms in foreign jurisdictions. Our relationships are derived from our curated list of global alliances, as well as our membership in the Multilaw network.

This isn’t the standard Am Law 100 model. However, when you put clients first, sometimes you have to create your own model. We believe that’s what a law firm should be.

Several recent proposals contemplate duties that would apply in addition to other applicable duties unless an exemption applies. In this report, we review 10 key tariff and trade developments shaping tariff exposure, supply-chain planning and customs compliance, and offer practical steps importers should consider now to assess cumulative duty exposure and prepare for potential changes.

U.S. Court of International Trade Invalidates Trump Section 122 Global Tariffs, the Administration Appeals, and Tariffs Likely Will Remain in Effect for Most Importers
Key Takeaways The U.S. Court of International Trade (CIT) invalidated President Trump’s Section 122 10% tariffs, holding that the Administration exceeded the authority delegated by Congress under Section 122 of the Trade Act of 1974. The Administration has appealed the decision to the U.S. Court of Appeals for the Federal Circuit. The CIT’s injunction is limited. The court granted relief only to the plaintiffs – the State of Washington, Burlap & Barrel and Basic Fun! – and declined to issue nationwide relief.
