9902.03.74 - 2,4-Xylidine (CAS No. 95-68-1) (provided for in subheading 2921.49.10)

This HTS category, 9902.03.74, specifically covers 2,4-Xylidine, identified by its CAS Number 95-68-1. It is crucial to note that while classified under Chapter 99, its primary substance is provided for in subheading 2921.49.10. This means that 2,4-Xylidine, an organic compound, falls under the broader classification of aromatic amines when considering its fundamental chemical properties. The inclusion within Chapter 99 signifies special provisions, likely temporary, that may alter the standard duty or import requirements for this specific chemical.

Distinguishing this category from its sibling entries within Chapter 99 is essential. Chapter 99 encompasses a wide array of temporary legislation, trade agreement modifications, and agricultural adjustments. While other 99xx codes might relate to specific temporary import restrictions or duty suspensions on various goods, 9902.03.74 is uniquely tied to the chemical compound 2,4-Xylidine. Its presence here does not denote a general class of goods but a specific chemical subject to special tariff treatment.

As a leaf node, HTS code 9902.03.74 does not have further subcategories. Therefore, the focus for classification purposes lies entirely on accurately identifying the substance as 2,4-Xylidine. Importers and customs brokers must confirm that the imported material precisely matches the chemical description and CAS number. Any deviations in chemical composition or purity could necessitate reclassification under a different, potentially standard, HTS code if not explicitly covered by the scope of this temporary provision.
