Overview
This HTS subheading, 2918.30.70.00, specifically enumerates certain organic compounds that feature both carboxylic acid and ketone functionalities, without possessing any other oxygen functional groups. The covered products include Dimethyl acetyl succinate, Oxalacetic acid diethyl ester, sodium salt, and specifically defined trifluorinated oxobutanoic acid esters (ethyl and methyl). These substances are typically utilized as intermediates in organic synthesis, particularly in the pharmaceutical and agrochemical industries, due to their reactive functional groups.
This category is distinguished from its sibling, 2918.30.90.00, which covers all other carboxylic acids with an aldehyde or ketone function but without other oxygen functions, not explicitly listed under 2918.30.70.00. Therefore, 2918.30.70.00 serves as an "enumerable" provision, capturing precise chemical entities that might otherwise fall under the broader "other" category. The specific naming and structural characteristics of the chemicals listed are the primary classification criteria here.
As this subheading represents a leaf node within the HTS, there are no further subcategories. Classification within this specific code is determined by the precise chemical identity of the imported or exported substance matching one of the enumerated compounds. Importers and exporters must ensure their documentation accurately reflects the specific chemical name and, where applicable, its salt form, to correctly classify goods under 2918.30.70.00.
