2933.39.23.00 - o-Paraquat dichloride

This HTS classification, specifically for o-Paraquat dichloride, falls under the broader category of pesticides, and more narrowly, herbicides, within the group of heterocyclic compounds containing an unfused pyridine ring. It encompasses the chemical compound identified as o-Paraquat dichloride, which is primarily known for its potent herbicidal properties. This designation is critical for identifying and accurately reporting this specific substance for customs purposes.

Distinguishing this code from its sibling, 2933.39.25.00, which covers "Other" herbicides, is straightforward. While both are herbicides, this particular code is reserved exclusively for o-Paraquat dichloride, a distinct chemical entity with specific properties and uses. The "Other" category would encompass any other herbicides that do not fit into the more specific classifications within this section.

As this classification represents a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification purposes remains on the precise identification of o-Paraquat dichloride. Importers and exporters should ensure that the product being declared precisely matches the chemical identity and intended use of o-Paraquat dichloride to avoid misclassification.
