Overview

This HTS category, 9902.03.23, specifically covers 2-Methyl-4-chlorophenoxyacetic acid (MCPA), a synthetic auxin herbicide. Its inclusion under Section XXII and Chapter 99 signifies it is subject to temporary legislation, trade agreement modifications, or additional import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. This means that while MCPA is fundamentally classified as a chemical compound under its primary HTS code (indicated as subheading 2918.99.20), this particular entry in Chapter 99 dictates specific import conditions or limitations beyond its standard tariff treatment.

Distinguishing this category from its sibling entries within Chapter 99 is crucial. The sibling categories, such as those starting with 0101 or 0102, pertain to live animals and represent entirely different classes of goods subject to distinct trade regulations. Therefore, 9902.03.23 does not compete for classification with agricultural products, live animals, or other broad categories found elsewhere in the HTS. Its unique position within Chapter 99 highlights its specialized regulatory status, separate from the general tariff classifications of many other goods.

As this is a leaf node within the HTS database, there are no further subcategories to explore. The classification is specific to MCPA under the outlined temporary provisions. The primary classification criteria are the chemical identity of the substance and its recognition under specific trade-related legislation. Importers must consult the governing trade agreements and Section 22 proclamations to understand the precise duties, quotas, or other import requirements applicable to MCPA when entered under this heading.
