Key Highlights

  • The Supreme Court ordered customs to start issuing refunds for tariffs paid under IEEPA, but the process is still being developed and may take time.
  • Importers are advised to protest their entries to preserve eligibility for refunds and protect their financial interests during this transition period.
  • Customs is working on the CAPE system, which will facilitate claims and refunds, with a 45-day deadline for implementation.
  • Tariffs remain unpredictable, with new duties like Section 122 imposing additional costs, and more tariffs are expected to be introduced under various legal authorities.
  • The ongoing trade changes pose compliance challenges, especially in valuing steel and aluminum content and managing Section 232 tariffs on auto parts, affecting parts pricing and industry stability.

The automotive aftermarket is continuing to navigate uncertainty following a recent U.S. Supreme Court decision on tariffs imposed under the International Emergency Economic Powers Act (IEEPA), according to Mark Tallo, managing partner at Sandler, Travis & Rosenberg during an Auto Care Association webinar on Wednesday.

During the webinar—Supreme Court Ruling on IEEPA and Other Key Trade Developments—Tallo said the ruling has created questions around refunds for previously paid tariffs.

“The court ordered customs to begin issuing refunds,” Tallo said, although he noted the process is still being developed and could take time to fully implement.

U.S. Customs and Border Protection is working on a new system—the Consolidated Administration and Processing of Entries (CAPE)—that would allow importers to submit claims and receive refunds through a structured process. The agency has been given 45 days to establish the system.

In the meantime, Tallo emphasized businesses should take proactive steps to protect their financial interests.

“We recommend that all importers protest their entries where IEEPA duties were paid,” he said, noting that doing so can help preserve eligibility for potential refunds.

Despite the ruling, tariffs remain a moving target. The administration has already introduced new tariffs under different legal authorities, including Section 122, which currently imposes a 10% duty for up to 150 days.

“There are more tariffs coming,” Tallo said. “The question is how companies position themselves to respond.”

Beyond refunds, the webinar also highlighted ongoing compliance challenges, including how to properly value steel and aluminum content and navigate existing Section 232 tariffs on auto parts.

For repair shops, the shifting tariff landscape could mean continued volatility in parts pricing. While the Supreme Court ruling may eventually lead to refunds for some importers, those savings won’t be immediate—and may not be passed down right away.

In the short term, parts costs could remain elevated. New tariffs, like the current Section 122 duties, are already replacing those that were struck down, and additional tariffs may be introduced under other trade laws.
