Overview

This HTS classification, 9902.11.14, covers specific chemical mixtures designated for temporary importation under special provisions. The product is characterized by its composition: a blend containing diphosphoric acid (approximately 20% or less), polymers of ethoxylated reduced methyl esters of reduced polymerized oxidized tetrafluoroethylene (CAS No. 200013-65-6), and a small quantity of 2-(2-methoxypropoxy)-1-propanol (CAS No. 34590-94-8). The balance of the mixture is water, and the polymeric component is provided for under subheading 3907.20.00, indicating its origin as a polymer or copolymer.

Chapter 99 of the Harmonized Tariff Schedule, to which this subheading belongs, is reserved for temporary legislation, trade agreement modifications, and specific import restrictions, notably under Section 22 of the Agricultural Adjustment Act. Therefore, this classification is distinct from standard permanent classifications found in earlier chapters. Unlike the broad categories of raw materials, finished goods, or general chemical compounds, this code applies to specialized chemical preparations that are subject to temporary and specific trade regulations, often related to agricultural or industrial policy.

As a leaf node, HTS 9902.11.14 has no further subcategories. Its specific chemical composition and the temporary nature of its classification under Chapter 99 are the defining criteria. Importers should consult the specific proclamations and regulations associated with this code for precise details regarding eligibility, duty treatment, and any quantity limitations that may apply. This classification underscores the dynamic nature of international trade regulations, allowing for the controlled importation of specific substances under particular economic or policy circumstances.
