9902.05.92 - 4-Amino-3,6-dichloro-2-pyridinecarboxylic acid (Aminopyralid) (CAS No. 150114-71-9) (provided for in subheading 2933.39.25)

This HTS category, 9902.05.92, specifically covers 4-Amino-3,6-dichloro-2-pyridinecarboxylic acid, also known as Aminopyralid. This chemical compound is an herbicide, a substance used to kill or inhibit the growth of unwanted plants. Its classification within Chapter 99 indicates that it is subject to specific temporary legislation or modifications, likely related to trade agreements or agricultural adjustment provisions. The provision "provided for in subheading 2933.39.25" signifies its underlying classification within the general chemical schedules, highlighting that its presence here is due to an additional import restriction or special treatment.

Unlike its sibling categories, which span a vast array of agricultural and manufactured goods from live animals to machinery, this specific subheading addresses a single, precisely defined chemical substance. The defining characteristic is its chemical identity and its designated purpose as an herbicide. Therefore, any product not precisely meeting the chemical description of 4-Amino-3,6-dichloro-2-pyridinecarboxylic acid, or not falling under the specific regulatory context of Chapter 99, would not be classified here.

As a leaf node, this category does not have further subcategories. Its precise nature means that further subdivision is unnecessary for classification purposes. The relevant classification criteria are the chemical identity (Aminopyralid, CAS No. 150114-71-9) and the specific temporary legislative provisions indicated by its presence in Chapter 99. Understanding these dual aspects is crucial for accurate customs declarations.
