2918.23.30.00 - Products described in additional U.S. note 3 to section VI

This HTS classification, 2918.23.30.00, specifically encompasses products described within additional U.S. note 3 to section VI, which fall under the broader category of "Other esters of salicylic acid and their salts." While this code denotes a specific subset of these esters and salts, its precise definition is contingent upon the detailed provisions of the aforementioned additional U.S. note. These products are derived from salicylic acid, featuring an ester linkage and potentially existing as salts, and are distinguished from other salicylic acid derivatives by the specific criteria outlined in that note.

The key differentiator for this classification lies in the specific criteria outlined in additional U.S. note 3. Without reference to this note, classifying a particular ester or salt of salicylic acid can be complex. This code serves to isolate a distinct group of these compounds that meet specific criteria beyond just being an ester or salt of salicylic acid, potentially related to their purity, intended use, or specific chemical modifications not covered by other subheadings.

As a leaf node within the HTS, 2918.23.30.00 does not have further subcategories. This means that any product falling under this specific classification is the most granular level of detail for this particular tariff line. Consequently, the focus for classification under this code is on accurately verifying if a product meets the requirements set forth in additional U.S. note 3, thereby confirming its precise placement within this specific sub-branch of salicylic acid esters and their salts.
