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 category, 9902.13.08, specifically covers modacrylic staple fibers that meet precise technical specifications. These fibers are characterized by their acrylonitrile content, ranging from 35% to 85% by weight, and a specific moisture content of 2% to 3% water. They are provided in an unpigmented or "ecru" state, are crimped to impart bulk and resilience, and possess a defined average decitex of 2.2 (with a tolerance of +/- 10%) and a fiber length of 51 mm (with a tolerance of +/- 10%). This detailed description ensures these fibers are differentiated based on their exact physical and chemical properties for customs purposes.

As a category within Chapter 99, which deals with temporary legislation and special provisions, this HTS code likely indicates a temporary modification or restriction that applies to the staple fibers classified under subheading 5503.30.00 in the main HTS structure. Therefore, while the core product is modacrylic staple fiber, its presence in Chapter 99 suggests a special import treatment or a specific quantitative limitation that is distinct from the general classification of these fibers. It is crucial to consult the full text of the temporary legislation associated with this code to understand its full implications for importation.

Since this HTS category is a leaf node, there are no further subcategories within 9902.13.08. Classification at this level is definitive, relying on the exact adherence to the described characteristics. Any deviation in acrylonitrile content, moisture level, pigmentation, crimp, decitex, or fiber length outside the specified tolerances would necessitate re-evaluation and potentially classification under a different HTS code, either within Chapter 99 or the permanent tariff schedule.
