3808.93.50.10 - Mixtures of 2-amino-4-[hydroxy(methyl)phosphonoyl] butanoic acid (glufosinate) or its salts or esters and application adjuvants

This HTS subheading classifies specific mixtures designed for agricultural use, primarily as herbicides. It encompasses formulations containing 2-amino-4-[hydroxy(methyl)phosphonoyl] butanoic acid, commonly known as glufosinate, along with its salts or esters. Crucially, these mixtures also include application adjuvants, which are substances added to enhance the effectiveness or application of the herbicide, such as surfactants, wetting agents, or drift retardants. The inclusion of these adjuvants is a defining characteristic of this category.

This category is distinct from its sibling, 3808.93.50.20, which specifically covers mixtures of glyphosate and application adjuvants. While both are herbicide formulations with adjuvants, the active herbicidal ingredient is the key differentiator: glufosinate for this subheading versus glyphosate for the other. The sibling category 3808.93.50.40, labeled "Other," would apply to mixtures containing different active herbicidal ingredients or those lacking the defined combination of a specific active ingredient and application adjuvants.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Therefore, classification under 3808.93.50.10 relies on the precise identification of glufosinate (or its salts/esters) and the presence of application adjuvants within the mixture. This ensures accurate tariff application for these specialized agricultural chemical products.
