2929.90.50.20 - Dialkyl (methyl, ethyl, n-propyl or isopropyl)-N,N-dialkyl (methyl, ethyl, n-propyl or isopropyl) phosphoramidates

This HTS classification covers dialkyl phosphoramidates where both the alkyl groups attached to the phosphorus and the nitrogen atoms are selected from methyl, ethyl, n-propyl, or isopropyl. These compounds are characterized by the presence of a phosphorus atom double-bonded to an oxygen atom, single-bonded to a nitrogen atom, and single-bonded to two alkoxy (dialkyl) groups. The specific selection of methyl, ethyl, n-propyl, or isopropyl groups for both the alkoxy and amino substituents is crucial for inclusion in this category.

This category is distinguished from its siblings by its specific chemical structure. Unlike phosphoramidic dihalides or phosphonamidic fluorides, the compounds classified here contain alkoxy groups directly attached to the phosphorus atom, in addition to the dialkylamino group. Furthermore, the scope is limited to dialkyl phosphoramidates where the alkyl substituents are restricted to the specified methyl, ethyl, n-propyl, or isopropyl options.

As a leaf node, this classification does not have subcategories. Therefore, the focus for classification within this HTS code is on accurately identifying the presence of dialkyl phosphoramidate functional groups with the specified alkyl substituents. Import and export professionals should carefully examine the chemical composition and structure of the product to ensure it precisely matches the definition provided.
