Overview

This HTS category, 9903.81.99, pertains to specific derivative products of iron or steel originating from the United Kingdom. The key differentiator for classification under this code lies in the goods being admitted to a U.S. foreign trade zone under "privileged foreign status" as defined by 19 CFR 146.41, and critically, prior to 12:01 a.m. eastern daylight time on June 4, 2025. This provision is an exception to other potential classifications within the 9903 series, specifically referencing subdivisions (s) and (t) of note 16 to this subchapter, and implies that these goods, while of UK origin and of iron or steel derivatives, benefit from a specific temporary modification or exception when handled under these stringent conditions.

Unlike the primary headings found in Chapters 1 through 98, which classify goods based on their inherent nature, material composition, and function, Chapter 99 addresses temporary legislation and modifications. Therefore, 9903.81.99 does not classify based on the physical characteristics of the iron or steel derivatives themselves, but rather on the specific trade policy treatment applied to them and their origin. This contrasts with sibling categories within Chapter 99, which would likely cover different temporary restrictions, trade agreement modifications, or specific additional import restrictions enacted under Section 22 of the Agricultural Adjustment Act, each with its own distinct set of criteria for application.

As this is a leaf node, there are no further subcategories or subdivisions within HTS 9903.81.99. Classification here is definitive based on meeting all the outlined conditions: the goods being derivative products of iron or steel from the United Kingdom, having been admitted to a U.S. foreign trade zone with privileged foreign status, and importantly, that admission occurring before the specified date and time. Any deviation from these exact requirements would necessitate re-evaluation under different HTS provisions.
