Section 232 Tarrifs: Thousands of Exclusion Requests from US Firms

Under Section 232 of the Trade Expansion Act of 1962, the Commerce Department conducted investigations to determine whether steel and aluminum import tariffs pose a threat to national security. On March 8, 2018, President Trump used the recommendations from these Commerce reports to impose a 25 percent tariff on imported steel and a 10 percent tariff on imported aluminum. A tariff is a tax levied on imported goods and paid by the importer.

In response to these increased costs, US firms and individuals that use steel and aluminum may file a request to be excluded from these tariffs. The exclusion request process is conducted by the Bureau of Industry and Security (BIS) of the Commerce Department, and all requests are made publicly available on regulations.gov. US producers of steel and aluminum have the ability to object to any exclusion request within 30 days of its submission. Multiple objections can be made for a single exclusion request.

As of June 17, 2019, there have been a total of 72,771 steel and aluminum tariff exclusion requests filed by 1,060 firms. The firms filing the exclusion requests represent 288 congressional districts for steel tariff exclusions and 149 congressional districts for aluminum tariff exclusions.

There have been 62,797 exclusion requests for an exemption from the steel tariffs, and steel manufacturers have filed 22,210 objections. The BIS has reached a decision on 70 percent of the steel exclusion requests; 30,545 (49 percent) have been approved, 13,261 (21 percent) have been denied, and 18,991 (30 percent) remain pending.

There have been 9,974 exclusion requests for an exemption from the aluminum tariffs, and aluminum manufacturers have filed 2456 objections. The BIS has reached a decision on 59 percent of the aluminum exclusion requests; 4,978 (50 percent) have been approved, 862 (9 percent) have been denied, and 4134 (41 percent) remain pending.
