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 code, 9902.13.35, covers specific types of acrylic staple fibers that have undergone processing for spinning, such as carding or combing. It is crucial to note that this classification is a temporary measure and applies only to acrylic staple fibers that meet a very precise set of criteria. These criteria exclude fibers containing 92% or more of polyacrylonitrile, and further restrict the zinc content to not more than 0.01%. Additionally, the water content must be between 2% and 8%. The classification also differentiates based on the decitex (a measure of fiber fineness), specifically covering those with an average decitex of 2.75 to 3.30, or 11 (with a 10% tolerance), or dyed fibers with an average decitex of 5.0 to 5.6.

This specific temporary provision is distinct from the general classifications for acrylic staple fibers found elsewhere in the HTS, such as under Chapter 55. The inclusion in Chapter 99 signifies that these fibers are subject to temporary modifications or restrictions, often related to trade agreements or specific import control measures. Unlike the broad categories of raw materials or processed fibers found in other chapters, this code targets a niche product with exacting specifications that are not covered by standard headings.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification process for goods falling under 9902.13.35 relies entirely on a thorough examination of the physical and chemical properties of the acrylic staple fiber to ensure it precisely matches all stipulated parameters. Importers must verify that the fiber's composition, water content, decitex, and dyeing status align with the detailed requirements outlined in the description to correctly apply this temporary provision.
