9902.03.75 - Mixed xylidines (CAS No. 1300-73-8) (provided for in subheading 2921.49.45)

This HTS category, 9902.03.75, specifically covers mixed xylidines, identified by CAS Number 1300-73-8. These chemical compounds are a group of aromatic amines derived from xylene. While their fundamental chemical identity places them within the broader scope of organic chemicals, their inclusion in Chapter 99 signifies specific temporary legislation or import restrictions. It's crucial to note that while the substance itself might otherwise be classified under Chapter 29 (Organic Chemicals), this 9900 series code indicates a distinct regulatory treatment applied to it.

As this is a leaf node within the HTS database, there are no further subcategories that subdivide this specific classification. Therefore, classification under 9902.03.75 is definitive for shipments of mixed xylidines meeting the stipulated conditions. Its parent context within Section XXII and Chapter 99 highlights that this entry is not a standard product classification but rather a provision related to temporary trade policies, agreements, or specific import controls. When encountering this code, importers and exporters must pay close attention to any associated notes or proclamations linked to this HTS number to ensure full compliance.
