3817.00.20.00 - Mixed alkylnaphthalenes

This HTS category, 3817.00.20.00, specifically encompasses mixed alkylnaphthalenes. These are chemical products characterized by the alkylation of naphthalene rings, resulting in a mixture of compounds where different alkyl groups are attached to one or more positions on the naphthalene structure. The primary distinction for this classification lies in the absence of these specific mixed alkylnaphthalenes from heading 2707 (products obtained from the distillation of coal tar or similar heavy oils) or heading 2902 (cyclic hydrocarbons). Therefore, this classification is reserved for alkylnaphthalenes that do not meet the criteria for those other specific headings, particularly concerning their origin or degree of processing.

While the sibling category "Mixed alkylbenzenes" covers similar alkylated cyclic hydrocarbons, the distinction is fundamental: this category is exclusively for naphthalene-based compounds, whereas the sibling pertains to benzene-based compounds. Naphthalene and benzene are distinct aromatic hydrocarbons with different molecular structures, leading to different chemical properties and applications for their respective alkylated derivatives. Therefore, proper classification hinges on correctly identifying the base aromatic ring system being alkylated.

As this is a leaf node, there are no further subdivisions within this HTS code. Classification under 3817.00.20.00 is final for goods meeting the description of mixed alkylnaphthalenes that are not specifically classified elsewhere. When faced with an import or export, careful analysis of the chemical composition, manufacturing process, and origin of the product is crucial to ensure it aligns with the definition of mixed alkylnaphthalenes and is not inadvertently placed under a heading for mixed alkylbenzenes or other specific chemical categories.
