Acetic acid — the primary component of vinegar in its dilute form — is a foundational industrial chemical used in the production of vinyl acetate monomer, purified terephthalic acid (PTA), and cellulose acetate. Its salts, including sodium acetate and calcium acetate, serve as food preservatives, de-icing agents, and textile auxiliaries. Trade classification can hinge on concentration and purity grade, as glacial acetic acid (near-anhydrous) is treated differently in commercial contracts than technical-grade solutions. Importers should verify whether specific salt forms fall under this heading or migrate to separate chemical headings depending on their intended use.
