9902.06.04 - 2-{[1-(4-Phenoxyphenoxy)-2-propanyl]oxy}pyridine (Pyriproxyfen) (CAS No. 95737-68-1)(provided for in subheading 2933.39.27)

This HTS category, 9902.06.04, specifically covers the insecticide Pyriproxyfen, identified by the chemical name 2-{[1-(4-Phenoxyphenoxy)-2-propanyl]oxy}pyridine and CAS Number 95737-68-1. Its inclusion within Chapter 99 signifies that it is subject to temporary legislation, trade agreement proclamations, or additional import restrictions under Section 22 of the Agricultural Adjustment Act. This specialized classification ensures that specific regulatory measures are applied to this particular chemical compound.

Distinguishing this category from its sibling entries within the broader HTS framework is crucial. While other HTS codes might classify general chemicals, pesticides, or organic compounds, 9902.06.04 isolates Pyriproxyfen due to its unique regulatory status. Unlike broader chemical categories that might encompass a wide range of substances with varied applications and import requirements, this node is precisely defined by the chemical identity and the temporary legislative provisions governing its entry.

As a leaf node, 9902.06.04 does not have further subcategories. This indicates that once a product is identified as Pyriproxyfen under its chemical nomenclature and CAS number, and meets the criteria for classification under Chapter 99, it is definitively placed within this specific code. Classification relies on verifying the chemical composition and ensuring compliance with any stipulated temporary import restrictions, rather than further subdivision based on product form or end-use.
