2933.39.21.00 - Fungicides 🖩

This HTS category, 2933.39.21.00, specifically classifies fungicides that contain an unfused pyridine ring within their chemical structure. These are organic chemical compounds designed for the prevention or eradication of fungal diseases in plants, crops, or other materials. The classification is rooted in the presence of a nitrogen heteroatom within a heterocyclic ring system, with the pyridine ring being a defining characteristic.

Distinction from its sibling category, Herbicides (which would fall under a separate classification), is based on the intended biological function. While both are pesticides, this specific subcategory is dedicated to agents that target fungi, whereas herbicides are designed to control unwanted plant growth. This emphasis on the targeted pest is a crucial element in accurate classification.

As this is a leaf node within the HTS, there are no further subdivisions under this specific code. Therefore, classification into 2933.39.21.00 hinges on confirming the presence of the pyridine ring and the declared function as a fungicide. If a product primarily functions as a fungicide and meets the structural requirements of containing an unfused pyridine ring, it would be classified here. Examples might include specific systemic or contact fungicides utilized in agriculture and horticulture.
