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, 9902.11.04, specifically addresses a specialized polymer, Poly(acrylic acid-co-(sodium 2-(acryloylamino)-2-methyl-1-propanesulfonate) sodium salt), identified by CAS No. 136903-34-9. The critical defining characteristic for classification under this provision is its granulated form. This particular designation is established under the umbrella of Temporary Legislation and Import Restrictions, indicating that its tariff treatment is subject to specific, potentially time-limited, proclamations.

Distinguishing this category from its sibling entries at the Chapter 99 level is crucial. The broader Chapter 99 encompasses a wide array of temporary trade measures, including modifications to tariff rates and import restrictions stemming from trade agreements and Section 22 of the Agricultural Adjustment Act. While siblings in this chapter might cover other goods subject to such temporary provisions, 9902.11.04 is uniquely reserved for this specific granulated polymer, differentiating it based on its precise chemical identity and physical form.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Therefore, the classification process for goods falling under 9902.11.04 relies entirely on verifying that the imported material is indeed Poly(acrylic acid-co-(sodium 2-(acryloylamino)-2-methyl-1-propanesulfonate) sodium salt) in granulated form. The reference to its underlying classification in subheading 3906.90.50 provides the permanent classification context for this polymer, but its inclusion in Chapter 99 signifies a temporary modification to that standard tariff treatment.
