9902.03.51 - N,N'-Bis(3-aminopropyl)ethylenediamine (CAS No. 10563-26-5) (provided for in subheading 2921.29.00)

This HTS classification, 9902.03.51, specifically pertains to N,N'-Bis(3-aminopropyl)ethylenediamine, identified by its CAS number 10563-26-5. This chemical compound falls under Chapter 99, which is dedicated to temporary legislation and modifications, including those related to trade agreements and Section 22 of the Agricultural Adjustment Act. While its primary chemical classification is found under subheading 2921.29.00, this 9900 series code designates a specific temporary measure or restriction impacting its importation.

The defining characteristic of this category is the application of a special provision to N,N'-Bis(3-aminopropyl)ethylenediamine, rather than its intrinsic chemical properties. Unlike the broad categories found in the initial chapters of the HTS (such as live animals in Chapter 01), this node exists within a section designed for dynamic trade policy adjustments. Therefore, its distinction from other sibling categories within Chapter 99 is not based on material or form, but on the specific temporary legislation or trade agreement modification it represents.

As a leaf node, HTS code 9902.03.51 does not have further subcategories. Classification under this specific code signifies that the importation of N,N'-Bis(3-aminopropyl)ethylenediamine is subject to the particular requirements or limitations stipulated by the temporary legislation or proclamation under which it is established. Users should consult the detailed notes and directives associated with this 9900 series code to understand the precise import procedures, duty rates, or quantitative restrictions that may apply.
