Overview
This HTS category, 9902.11.64, specifically covers an ion-exchange resin with a precisely defined chemical composition: a copolymer of acrylonitrile with divinylbenzene, ethylvinylbenzene, and 1,7-octadiene, which has undergone hydrolysis. The CAS number 130353-60-5 is provided as an additional identifier for this particular substance. Its placement within Chapter 99 signifies that it is subject to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, or additional import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act, as amended. This classification is a temporary designation for goods otherwise classified under subheading 3914.00.60, indicating a deviation from standard classification due to specific trade or agricultural policy measures.
Unlike the sibling categories, which are generally broad classes of live animals, this HTS code focuses on a highly specific manufactured chemical product. The distinction lies in the material itself (a synthetic polymer resin) and its intended industrial application as an ion-exchange material, rather than the nature of live organisms. While other categories within Chapter 99 might cover different temporary trade provisions for a variety of goods, this particular subheading is narrowly tailored to this specific hydrolyzed ion-exchange resin, reflecting unique policy considerations that apply to its importation.
As this is a leaf node, there are no subcategories to introduce. The classification is complete at this level, meaning that any import of the ion-exchange resin described herein will be subject to the temporary measures associated with HTS code 9902.11.64. Importers should consult relevant U.S. Customs and Border Protection (CBP) rulings and the specific text of Section 22 proclamations for detailed requirements, duties, and any quantitative limitations that may apply to this classification.
