2917.37.00.00 - Dimethyl terephthalate

This HTS category, 2917.37.00.00, specifically covers Dimethyl terephthalate. Dimethyl terephthalate is an organic chemical compound derived from terephthalic acid, characterized by its structure as the dimethyl ester of terephthalic acid. It serves as a crucial intermediate in the production of polyester fibers and films, most notably polyethylene terephthalate (PET). Its classification under aromatic polycarboxylic acids reflects its chemical composition and functional groups.

Distinguishing this entry from its siblings is vital for accurate classification. For instance, while 2917.32.00.00 and 2917.33.00 refer to different orthophthalate esters (dioctyl, nonyl, or decyl), 2917.37.00.00 is specifically for the *dimethyl* ester of *terephthalic* acid. Other sibling entries like 2917.35.00.00 (Phthalic anhydride) and 2917.36.00.00 (Terephthalic acid and its salts) represent different chemical forms or related but distinct compounds within the aromatic polycarboxylic acid family.

As this is a leaf node, there are no further subcategories within 2917.37.00.00. Classification under this code is final for Dimethyl terephthalate. When classifying, focus on confirming the chemical identity and purity of the substance to ensure it aligns with the definition of Dimethyl terephthalate and is not a derivative or impurity that might fall under a different HTS heading.
