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 code, 9902.13.03, specifically covers acrylic filament tow. These are bundles of synthetic fibers made from polyacrylonitrile, characterized by precise specifications. Key defining features include a high percentage of polyacrylonitrile (92% or more), minimal zinc content (not exceeding 0.01%), and controlled water content (between 2% and 8%). The tow is dyed and presented in crimped bundles, each containing a specific number of filaments (214,000 ± 10%) with a defined average decitex (3.3 ± 10%) and a length exceeding 2 meters. Its inclusion under Section XXII signifies it falls under temporary legislation or special provisions, likely related to trade agreements or agricultural adjustments, and is further categorized within Chapter 99, which deals with temporary measures.

Distinguishing this category from its siblings is crucial. While the provided sibling examples (e.g., live animals) represent entirely different product groups with distinct biological and agricultural classifications, 9902.13.03 addresses a specific type of manufactured textile intermediate. Unlike standard textile fibers or yarns which would be classified under Chapter 55, this particular acrylic filament tow is designated under Chapter 99 due to its specialized nature and the temporary or modified import status it holds under this specific HTS provision. Its strict technical parameters differentiate it from other acrylic tows that might not meet these precise weight, filament count, decitex, or length requirements, or those not subject to the specific temporary legislation applicable here.

As this HTS code is a leaf node, it does not have further subdivisions. Therefore, the focus remains on the precise definition and criteria outlined in the description. Importers and customs officials should carefully verify that the imported acrylic filament tow precisely matches all the stated characteristics, including the material composition, the presence and limits of zinc and water, the filament count and decitex, and the length, as well as confirming its eligibility under the temporary provisions of Chapter 99. Any deviation from these specifications may result in a different HTS classification.
