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 classification, 9902.11.73, pertains to a specific type of chemical compound: Chloromethylated, trimethylamine-quaternized poly(divinylbenzene-co-styrene-co-ethylstyrene) (CAS No. 69011-19-4). This material is a synthetic polymer with specialized chemical modifications, designed for particular applications. Its presence within Chapter 99 indicates it is subject to temporary legislation or specific import restrictions, often due to trade agreements or agricultural policy adjustments, and is provided for under subheading 3914.00.60, which generally covers specific synthetic polymers.

Distinguishing this category from its sibling HTS codes, which primarily deal with live animals, is straightforward. While sibling categories focus on biological commodities, 9902.11.73 covers a precisely defined manufactured chemical substance. The classification is based on the specific chemical structure and intended use of this modified polymer, rather than on living organisms.

As this is a leaf node within the HTS, there are no further subcategories. The classification for Chloromethylated, trimethylamine-quaternized poly(divinylbenzene-co-styrene-co-ethylstyrene) is definitive at this level. Importers and customs officials should rely on the detailed chemical description and CAS number for accurate identification, noting its classification within Chapter 99 signifies its unique regulatory status beyond standard polymer classifications.
