The Department of Commerce’s Bureau of Industry and Security (“BIS”) issued a Federal Register Notice which is due to be published on May, 19, 2020, inviting comments from interested parties on its investigation regarding the potential expansion of Section 232 tariffs to include imports of steel incorporated into electrical transformers. Comments on the investigation may be submitted on or before June 9, 2020 and rebuttal comments on or before June 19, 2020 (21 and 31 days after publication, respectively). All written comments must be addressed to “Section 232 Electrical Steel Investigation” and filed through the Federal eRulemaking Portal at http://www.regulations.gov/ under docket number BIS-2020-0015. While comments are being solicited, there is no further specificity as to the products that are being investigated and therefore affected parties should anticipate submitting comments if their products are associated with laminated or wound cores for use in transformers.
