Overview

This HTS classification, 9902.10.33, covers a specific chemical substance identified as 1,3-Propanediamine, N,N”-1,2-ethanediylbis-, polymer with 2,4,6-trichloro-1,3,5-triazine, reaction products with N-butyl-2,2,6,6-tetramethyl-4-piperidinamine, and its associated CAS number 136504-96-6. Importantly, this classification is not a permanent HTS designation but rather a temporary modification or restriction proclaimed under specific trade agreements legislation or Section 22 of the Agricultural Adjustment Act. Its inclusion in Chapter 99 indicates that its tariff treatment is subject to special, often temporary, provisions distinct from the general commodity chapters.

Given that this is a leaf node within Chapter 99, there are no further subcategories to explore. The primary purpose of this classification is to identify and control the import of this particular chemical substance, likely due to specific policy objectives, trade negotiations, or agricultural protection measures. When classifying goods, it is crucial to recognize that items falling under Chapter 99 supersede their potential classifications in other chapters by imposing specific conditions or duty rates. Therefore, any importer dealing with this chemical must carefully review the specific details and duration of the temporary legislation associated with HTS code 9902.10.33.
