2933.39.61.20 - 1-[N,N-Dialkyl (≤C10)-N-(n-(hydroxyl, cyano, acetoxy)alkyl (≤C10)) ammonio]-n-n-[N-(3- dimethylcarbamoxy-α-picolinyl)-N,N-dialkyl (≤C10) ammonio]decane dibromide (n=1-8) 🖩

This HTS classification, 2933.39.61.20, covers specific quaternary ammonium compounds, characterized by a decane backbone with two such ammonio groups. These compounds feature complex substituents including N,N-dialkyl groups (with alkyl chains up to C10) and n-alkyl chains (with hydroxyl, cyano, or acetoxy functionalities, also up to C10). The presence of the "ammonio" functionality and the dibromide counterions are critical identifiers for goods falling under this subheading.

This subheading is distinguished from its siblings by the specific structure of the quaternary ammonium compounds it covers. Unlike 2933.39.61.10, which pertains to 3-Quinuclidinyl benzilate, or 2933.39.61.30, which describes bis-quaternary ammonium compounds with dione functionalities, this subheading is precisely defined by the decane dibromide structure with specific hydroxyl, cyano, or acetoxy-substituted alkyl groups. Category 2933.39.61.91 encompasses all other unclassified items at this level.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification into 2933.39.61.20 requires that the imported or exported goods precisely match the detailed chemical description provided, including the length of the alkyl chains and the specific functional groups attached. The primary classification criteria are the unique molecular structure and the presence of the specified quaternary ammonium salts.
