A report issued late Thursday by US Customs and Border Protection indicates that the temporary exclusions for US steel tariffs under Section 232 will expire as of May 1. Starting that day, all countries of origin will be subject to the 25 percent tariff on US steel imports.

The tariffs are effective with respect to goods entered, or withdrawn from warehouse for consumption, on or after March 23, 2018. Countries with temporary exclusions to the tariffs include Canada, Mexico, Australia, Argentina, South Korea, Brazil and  member countries of the European Union (Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and the United Kingdom).

Customs and Border Protection noted that exclusions are based on the country of origin, not the country of export. The merchandise covered by the additional duties may also be subject to pre-existing antidumping and countervailing duties.
