The U.S. Chamber of Commerce urged the Trump administration to implement a "tax exclusion process" immediately to prevent the U.S. economy from falling into a recession and causing "irreparable harm" to small businesses.

In a letter first obtained by CNBC, a large-scale business lobbying team asked Trump’s main trade officials to automatically raise tariffs on all small business importers and all “products that cannot be produced in the United States” or products that cannot be available at home.

The letter from the conference hall CEO Suzanne Clark also asked the Trump administration to establish a process for businesses to quickly obtain tariff exclusions if they can prove that import taxes “are significant risks to U.S. employment.”

"We are deeply concerned that even if it only takes weeks or months to reach an agreement, many small businesses will suffer irreparable harm," Clark wrote in a letter to Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick and U.S. Trade Representative Jamieson Greer later Wednesday.

“The Chamber of Commerce asked the government to take immediate action to save small businesses in the United States and avoid recession,” she wrote.

Clark said in an interview on CNBC’s “Scream on the Street” Thursday morning that she wrote about the White House because “we were just overwhelmed by the information requested by small businesses for relief.”

She said the business owners were “feared that their business survived.”

Clark also explained why the chamber chose not to challenge Trump's tariffs in court, as others have done – even though her panel has sued the Biden administration more than 20 times.

"We do worry about over-management of the government" and "micromanagement". "But in this case, the court takes a long time. What small businesses need, what all businesses need, and that's more direct relief."

When the Trump administration was considering the Chamber of Commerce’s requirement for exemptions in a press conference, White House Vice President Stephen Miller suggested not.

“Remedies for small businesses will be generated in the form of the largest tax cut in U.S. history,” he said.

Miller also said President Donald Trump “clearly” that companies investing in the U.S. will not be liable for tariffs.

Miller said he rejected his idea of ​​rejecting short-term tariff cuts, and Miller said: "This is a tax cut for small businesses. Again, you only pay tariffs for products made outside the United States."
