9902.09.39 - Mixtures of methyl (1E)-N-[(methylcarbamoyl)oxy]ethanimidothioate (Methomyl) (CAS No. 16752-77-5) and application adjuvants (provided for in subheading 3808.91.50)

This HTS classification covers specific mixtures containing Methomyl, a known insecticide, combined with application adjuvants. The CAS number 16752-77-5 specifically identifies Methomyl. The inclusion of application adjuvants signifies that these are formulated products designed for enhanced efficacy or ease of use in agricultural or pest control applications, and these adjuvants themselves are generally classified under subheading 3808.91.50.

Given that this is a leaf node within Chapter 99, it represents a very specific, temporary, or special import provision rather than a broad product category. Therefore, direct sibling comparisons within Chapter 99 are not applicable in the same way as comparing physical goods. This code is distinct from broader product categories found in other chapters of the HTS. Its presence in Chapter 99 signifies a specific, likely time-limited, duty or restriction status that overrides standard classifications found elsewhere in the HTS for these particular chemical mixtures.

The purpose of this classification is to manage the import of these specific Methomyl-based mixtures under special circumstances, such as temporary trade agreements or Section 22 of the Agricultural Adjustment Act. It highlights that while the core chemical (Methomyl) and its typical application context would otherwise fall under different sections of the HTS, this specific classification is established for regulatory or policy reasons to control or monitor their importation.
