About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 9902.06.39, is a specific provision within Chapter 99 of the Harmonized Tariff Schedule, which covers temporary legislation and special classification provisions. This particular code designates the compound 3-[(1S,2S)-2-Hydroxycyclohexyl]-6-[(6-methyl-3-pyridinyl)methyl]benzo[h]quinazolin-4(3H)-one, identified by CAS No. 1227923-29-6. Its inclusion in Chapter 99 signifies that its tariff treatment is subject to temporary modifications, trade agreements, or specific import restrictions, and it is provided for under the more general subheading 2933.59.53.

Given that this is a leaf node within the HTS database, it does not have further subcategories. Its classification is highly specific, referring to a single, precisely defined chemical compound. Unlike sibling categories in Chapter 99 which might cover broad classes of goods subject to temporary measures (e.g., temporary duty reductions on certain raw materials), this node is dedicated to a particular pharmaceutical intermediate or active ingredient. The distinction lies in its molecular structure and its potential use, which is governed by the specific temporary legislation or trade agreement provisions that led to its inclusion under this 9902 subheading.

The primary classification criteria for this node are the precise chemical identity and structure of the substance. Importers must ensure they are dealing with the exact compound 3-[(1S,2S)-2-Hydroxycyclohexyl]-6-[(6-methyl-3-pyridinyl)methyl]benzo[h]quinazolin-4(3H)-one, as minor variations in molecular structure would necessitate classification under a different HTS code. The presence of the CAS number is crucial for definitive identification, and the reference to subheading 2933.59.53 indicates its origin within a broader category of heterocyclic compounds containing a pyrimidine ring, before being subjected to the special provisions of Chapter 99.
