9903.80.03 - Derivative iron or steel products enumerated in U.S. note 16(a)(ii) to this subchapter, except products of Argentina, of Australia, of Brazil, of Canada, of Mexico (as specified in subdivision (h)(ii) of such U.S. note 16), of South Korea, of member countries of the European Union enumerated in note 16(f) to this subchapter or of Japan, or of the United Kingdom, or of Ukraine entered under the terms of such U.S. note 16,or any exclusions that may be determined and announced by the Department of Commerce

HTS Code 9903.80.03 specifically designates derivative iron or steel products subject to particular trade restrictions, as outlined in U.S. Note 16(a)(ii) to this subchapter. This classification pertains to goods that have undergone processing beyond basic forms of iron or steel and are subject to these specific import limitations. It is crucial to note that this category includes extensive exclusions for products originating from a list of specified countries, including Argentina, Australia, Brazil, Canada, Mexico (under specific conditions detailed in the note), South Korea, certain member countries of the European Union, Japan, the United Kingdom, and Ukraine. Furthermore, any product that has been granted an exclusion by the Department of Commerce is also outside the scope of this particular HTS code.

This category operates within the broader framework of Temporary Legislation and Additional Import Restrictions outlined in Section XXII and Chapter 99 of the HTSUS. While sibling categories in Chapter 01, for instance, deal with live animals, HTS 9903.80.03 addresses a very specific subset of manufactured goods, namely derivative iron or steel products, that are subject to targeted import controls rather than standard commodity classifications. Its purpose is to implement specific trade policy measures that supersede the general tariff treatment for these particular goods.

As a leaf node, HTS Code 9903.80.03 does not have further subdivisions. Therefore, the classification hinges entirely on meeting the criteria of being a derivative iron or steel product as defined by the referenced U.S. note and not falling under any of the numerous country-specific exclusions or individual product exclusions granted by the Department of Commerce. Importers must carefully review U.S. Note 16 in its entirety to determine if their goods fall within the scope of this provision or are exempt due to origin or exclusion.
