Overview

This HTS category, 9902.04.24, specifically covers 1,1,3,3-Tetrabutylurea (CAS No. 4559-86-8). While its primary classification lies within Chapter 29, covering organic chemicals, this particular entry is placed under Section XXII. This section pertains to temporary legislation, trade agreement modifications, and specific import restrictions enacted under Section 22 of the Agricultural Adjustment Act, as amended. Therefore, this classification indicates that 1,1,3,3-Tetrabutylurea is subject to unique import provisions beyond its standard chemical tariff treatment.

Distinguishing this category from its siblings at the root level is straightforward, as Chapter 99, where this node resides, is entirely distinct from the main Chapters of the HTS (like Chapters 1-97) that classify goods based on their inherent nature and composition. The siblings listed (e.g., live animals) fall under completely different sections and chapters, covering a vast range of unrelated products. The purpose of Chapter 99 entries is to implement specific, often temporary, trade policies or restrictions, rather than to classify goods based on their fundamental characteristics.

As this is a leaf node, there are no further subcategories within 9902.04.24. Classification under this code signifies that 1,1,3,3-Tetrabutylurea is subject to the specific temporary measures or restrictions stipulated by the legislation referenced in Section XXII, and no further breakdown of this particular provision exists. Importers must consult the accompanying notes and legal texts for Section XXII to understand the precise requirements and limitations associated with this classification.
