A federal appeals court has temporarily reinstated president Donald Trump’s controversial tariffs, pausing a lower court’s ruling that deemed them unlawful.
The move restores, for now, Trump’s ability to impose sweeping import duties under emergency economic powers, throwing a fresh wrench into already volatile supply chains for B2B ecommerce firms.
The ruling by the U.S. Court of Appeals for the Federal Circuit effectively reverses a May 28 decision from the Court of International Trade. That decision found that Trump overstepped his authority under the International Emergency Economic Powers Act (IEEPA). The appeals court has now ordered both sides to submit formal arguments by early next month, leaving the legal status of the tariffs — and their business impact — in limbo.
For B2B ecommerce leaders like Grainger, Fastenal, and MSC Industrial, the court’s reversal means continued instability. The initial ruling had promised cost relief and greater predictability in sourcing and procurement. Now, those gains are on hold.
“This is a legal ping-pong match,” said Kathleen Brooks, research director at XTB UK. “Just as businesses start to plan for tariff rollbacks, they’re forced to pivot again. It’s exhausting and inefficient for procurement teams.”
Analyst insights about the court ruling on tariffs
The Court of International Trade had concluded that Trump’s use of emergency powers to impose baseline 10% duties on all foreign goods — and even steeper rates on strategic imports — was an overreach. The decision would have reshaped pricing models and improved margin visibility across the B2B ecommerce space.
But the immediate appeal underscores the Trump campaign’s determination to keep tariffs central to its economic platform. Trump has repeatedly argued that the measures are essential to revitalize American manufacturing — despite warnings that they raise input costs for distributors, wholesalers, and industrial suppliers.
“Small and midsize B2B players are the real collateral damage here,” said Carl Weinberg, chief economist at High Frequency Economics. “They lack the pricing power to pass on these costs and the legal resources to hedge against regulatory swings.”
With the appellate court’s pause in place, B2B ecommerce firms are bracing for continued disruption. The Trump administration has so far remained silent on the ruling but may soon face pressure to clarify its trade posture amid growing industry unease.
“Legal outcomes aside, what companies need most is predictability,” said Ulrike Hoffmann-Burchardi of UBS Global Wealth Management. “Without it, capital planning, supplier contracts, and even basic inventory decisions become high-risk bets.”
Analysts now urge B2B operators to stay agile — monitor court developments closely, diversify sourcing partners, and lock in pricing where possible. The next major development will hinge on the written arguments due in early June. Those arguments could determine whether the U.S. curtails, restructures, or permanently reinstates these tariffs.
In the meantime, the pause leaves B2B ecommerce in a familiar spot caught between politics and policy and forced to navigate a regulatory landscape that shifts as quickly as a shipping schedule.
