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, 9902.02.71, specifically covers (3E)-4-Ethoxy-1,1,1-trifluorobut-3-en-2-one, identified by CAS No. 59938-06-6. This chemical compound is a specialized intermediate, primarily used in the synthesis of other chemical products. Its inclusion within Chapter 99 signifies its treatment under temporary legislation or special provisions, distinct from standard commodity classifications.

Unlike the primary chapters of the Harmonized Tariff Schedule that classify goods by their inherent nature (e.g., live animals, machinery, textiles), Chapter 99 categories are dynamic and subject to policy changes. This particular subheading's reference to subheading 2914.79.90 indicates that the base classification for this chemical would typically fall under the broader category of other ketones and aldehyde-alcohols, aldehydes, ketone-alcohols, and their cyclic acetals and hemiacetals, and derivatives, not elsewhere specified or included. However, its placement here under 9902.02.71 suggests specific import conditions or duties apply.

As this is a leaf node, there are no further subcategories. Classification at this level is definitive, meaning the specific chemical identity and its designated tariff provision are the sole determining factors. Understanding the underlying classification in 2914.79.90 provides context for the chemical family, but the 9902.02.71 code highlights a special trade or regulatory treatment for this particular fluorinated ketone derivative.
