Application of Reciprocal Tariffs under EO 14257 The non-aluminum content of an article reported on a separate line per the instructions above is subject to Reciprocal tariffs under HTS 9903.01.25. The aluminum content subject to Section 232 duties per the instruction above is not subject to Reciprocal tariffs under HTS 9903.01.33. Duties for Aluminum from Russia The 200 percent duty on any aluminum products and derivative aluminum products subject to Section 232 that are products of Russia, or where any amount of primary aluminum used in the manufacture of the aluminum articles is smelted in Russia, or where the aluminum articles are cast in Russia, is still in effect. These duties are to be applied to the entire value of the imported good. Importers should continue to report HTSUS heading 9903.85.67 for aluminum products; and heading 9903.85.68 for aluminum derivative products; subject to the 200 percent Russia aluminum duties. 9903.85.68 and 9903.85.70: Derivative aluminum articles that are products of Russia, or where any amount of primary aluminum used in the manufacture of the aluminum articles is smelted in Russia, or where the aluminum articles are cast in Russia, when such derivative articles are provided for in the headings or subheadings enumerated in note 19(a)(iii) or notes 19(i), 19(j) or 19(k) as applicable per the date of entry for consumption or withdrawal from warehouse for consumption. Smelt and Cast Reporting Requirements To report the primary country of smelt, secondary country of smelt, or country of most recent cast. Importers must report the International Organization for Standardization (ISO) code on aluminum articles and derivative aluminum articles on all countries subject to section 232. Filers must report “Y” for primary country of smelt; and/or secondary country of smelt. Filers may not report “N” for both primary country of smelt and secondary country of smelt. For the Importer's Additional Declaration Record Type '07' if either the derivative aluminum primary and/or secondary country of smelt or country of cast is unknown, report ‘UN’ (unknown) for the ISO country code. When reporting ‘UN’, the 200 percent Section 232 duties for Russia aluminum will be assessed on the entry summary line. If the imported aluminum is manufactured only from recycled aluminum, then filers should report “Y” for the secondary country of smelt, and report the country reported as the country of origin of the imported article as the secondary country of smelt code. Take note that aluminum manufactured only from recycled aluminum is not common. Importers must be able to provide manufacturing documents, upon request, to substantiate the manufacturing process for the recycled aluminum product. Country of Origin: If the imported product was smelted and cast in the United States, then the importer will report “US” for the country of smelt and “US” for the country of cast.
