SITCSection 5
U.S. exports of acetic acid and its salts (SITC 51371) totaled $27.0M in July 2026.
Importers of Acetic Acid and Its Salts paid $845K in duties in July 2026 — an effective duty rate of 17% on $4.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAcetic 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.

Glacial acetic acid (typically 99%+ purity) and lower-concentration technical or food-grade solutions are all captured under this heading, but commercial contracts and safety documentation must reflect the correct concentration. Customs brokers should confirm that dilute acetic acid preparations are not reclassified as vinegar or food preparations under a different schedule.
Vinyl acetate monomer (VAM) production, purified terephthalic acid (PTA) for polyester fibers, and cellulose acetate for film and textiles are the dominant end-use sectors. Demand from these industries makes acetic acid a closely watched petrochemical feedstock in supply-chain planning.
