Overview

This HTS code, 9902.07.43, specifically covers Isoxadifen-ethyl (CAS No. 163520-33-0), a chemical compound identified as Ethyl 5,5-diphenyl-4H-1,2-oxazole-3-carboxylate. This classification falls under Chapter 99, which pertains to temporary legislation and special provisions, indicating that its import is subject to specific regulations beyond standard tariff classifications. The parenthetical reference to subheading 2934.99.39 highlights its underlying classification within the "Other heterocyclic compounds" category of Chapter 29, but its presence in Chapter 99 signifies a distinct, temporary control or provision.

As a leaf node within Chapter 99, there are no further subdivisions under this specific HTS code. Therefore, the primary focus for classification professionals is on accurately identifying Isoxadifen-ethyl. This involves verifying the chemical name, CAS number, and the specific nature of the material as a designated temporary or specially regulated import. Unlike other entries in Chapter 99, which might cover broad categories of goods subject to temporary modifications, this code is highly specific to a single chemical compound and its associated special import requirements.
