While the China tariffs have at times split the industry—mold makers, for example, mounted an aggressive campaign in favor of tariffs while some plastics processors sought exclusions from mold tariffs—ACC and its large chemical and resin company members have consistently opposed the tariffs, partly because they worried U.S. resin exports could face retaliation.
In a statement, ACC said the Senate's motion to instruct, a process known as MTI, was a step forward.
"By reopening and extending the exclusions process for Section 301 tariffs, the proposed MTI would be an important first step toward alleviating the economic burden tariffs have caused to American businesses and consumers," ACC said.
ACC said the tariffs, which were put in place by the administration of President Donald Trump under what's widely referred to as Section 301 of U.S. trade laws, did not reduce U.S. chemical imports but did hurt domestic manufacturing.
"The tariffs largely disrupted the U.S. chemical industry's supply chains and business operations," ACC said. "It's time to bring an end to these burdensome tariffs."
The sponsor of the Senate exclusion amendment, Sen. Pat Toomey, R-Penn., said in a May 4 statement that the Trump administration created an exclusion process for its tariffs but said President Joe Biden's government has "thus far failed to fully reinstate this exclusion process."
"American manufacturing must be able to effectively compete with everyone, including China," Toomey said. "With a Section 301 tariff exclusion process, American manufacturers will be better positioned to obtain the materials they need for production."
The Senate voted 53-43 in favor of the exclusion process, but the House version of the domestic manufacturing bill does not contain similar exclusion language.
In a speech on the Senate floor, Sen. Sherrod Brown, D-Ohio, urged the body to reject Toomey's plan, saying it would weaken incentives to invest in U.S. manufacturing.
"These tariffs are in place because of Chinese unfair trade practices that target our industrial base and jobs in Pennsylvania and Ohio and New Jersey," Brown said. "Creating an overly broad exclusion process that ties our hands would take away leverage we need to pressure China to change its behavior."
Brown said unions, some manufacturers and U.S. Trade Representative Katherine Tai oppose Toomey's amendment.
Toomey, however, said in the Senate chamber that his plan would only seek to reestablish an exclusion process that has lapsed and would not repeal existing China tariffs or prevent new ones from being put in place.
The exclusion language also gives "considerable flexibility" to Tai's office, Toomey said. A similar plan passed the Senate last year on a 91-4 vote, he said.
"The bipartisan language simply helps ensure that American manufacturers remain competitive," Toomey said. "Nearly every one of us submitted letters of request from constituent companies asking for exclusions."
ACC is part of a broader manufacturing coalition that submitted a letter May 2 to congressional leaders, urging support for an exclusion process and saying that an alternative plan put forward by Tai's office was too limited. That letter was also signed by the Vinyl Institute and the Window and Door Manufacturers Association.
