Overview
This HTS code, 9902.04.21, pertains to N-Ethenylformamide, also known as N-vinylformamide, with the CAS number 13162-05-5. This classification falls under Chapter 99, which is reserved for temporary legislation, modifications to trade agreements, and import restrictions imposed under Section 22 of the Agricultural Adjustment Act. Specifically, this entry provides for N-vinylformamide when it is subject to these special provisions, often indicating a temporary duty rate or quantitative restriction. It is important to note that the principal HTS classification for N-vinylformamide, when not subject to these temporary measures, is found under subheading 2924.19.11, which covers its general chemical classification as an amide.
Distinguishing this category from its sibling entries within Chapter 99 requires an understanding of the specific temporary legislation or trade agreement modifications in effect at any given time. While other entries in Chapter 99 might address temporary duties or restrictions on different agricultural commodities or manufactured goods, 9902.04.21 is precisely targeted at N-vinylformamide. Therefore, the primary differentiator is the controlled commodity itself and the specific legal basis for its inclusion under Chapter 99. The context of Section 22 of the Agricultural Adjustment Act often implies that such measures are related to the protection of domestic agricultural programs or preventing imports from disrupting such programs.
As this is a leaf node within the HTS database, there are no further subcategories. Classification under 9902.04.21 is final for N-vinylformamide when it is subject to the specific temporary provisions outlined in this code. Importers must verify the current status of any temporary legislation or proclamations related to this HTS number to ensure accurate duty assessment and compliance with any applicable restrictions. The reference to subheading 2924.19.11 serves as a reminder of the underlying classification of the chemical, which is superseded by the special provisions when they are invoked.
