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, 9902.09.21, specifically covers product mixtures containing two defined active insecticidal ingredients: Imidacloprid (CAS No 138261-41-3) and β-Cyfluthrin (CAS No. 68359-37-5). These mixtures are designated for use as insecticides, and their classification under Chapter 99 signifies they are subject to specific temporary legislation, trade agreement modifications, or additional import restrictions proclaimed pursuant to Section 22 of the Agricultural Adjustment Act, as amended. The parent context within Section XXII highlights that this category falls under special provisions, distinct from the standard commodity classifications found in earlier chapters of the HTS.

Distinguishing this category from its sibling HTS codes is crucial. While other Chapter 99 headings might address temporary import restrictions on various goods, 9902.09.21 is uniquely tied to these specific insecticidal product mixtures. Its siblings, such as those covering live animals (e.g., 0101 for horses, 0102 for bovine animals), are entirely unrelated in terms of the product type and the regulatory framework they fall under. The defining characteristic here is not the commodity itself, but the specific combination of active ingredients and the overlay of special import regulations.

As this is a leaf node within the HTS database, there are no subcategories to introduce. Therefore, classification under 9902.09.21 relies directly on the precise identification of the Imidacloprid and β-Cyfluthrin components within the imported product mixture, and confirmation that the mixture is indeed subject to the temporary legislation or restrictions referenced by its Chapter 99 designation. The description provided, including the CAS numbers, serves as the primary practical classification criteria, ensuring that only these specific formulated insecticides are captured by this tariff code.
