SITCSection 5
U.S. imports of unsaturated acyclic monocarboxylic acids (nes) and cyclic monocarboxylic acids, anhydrides, and derivatives (SITC 51379) totaled $48.1M in July 2026, traded with 43 countries.
Importers of Unsaturated Acyclic Monocarboxylic Acids (NES) and Cyclic Monocarboxylic Acids, Anhydrides, and Derivatives paid $6.2M in duties in July 2026 — an effective duty rate of 17% on $36.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.

Benzoic acid and its derivatives — including sodium benzoate, one of the most widely used food preservatives globally — are among the most commercially significant compounds in this broad residual heading, alongside acrylic acid, sorbic acid, and cyclic acids such as cyclohexanecarboxylic acid. Acrylic acid in particular is a high-volume petrochemical monomer used in superabsorbent polymers, coatings, and adhesives, and its trade has been subject to antidumping scrutiny in several markets. The heading's NES and cyclic scope makes it a classification catch-all, so precise chemical identification — including whether a compound is acyclic or cyclic — is essential for correct entry.

Acrylic acid (propenoic acid) falls under this heading as an unsaturated acyclic monocarboxylic acid NES, while methacrylic acid (2-methylpropenoic acid) has its own dedicated SITC heading (51373). The two are structurally similar but commercially distinct monomers with different polymer applications; importers must specify the correct compound name and CAS number to ensure proper classification.
Sodium benzoate is generally recognized as safe (GRAS) for food use in the US within specified concentration limits, but imported product intended for food applications should be accompanied by a certificate of analysis confirming purity and absence of prohibited contaminants. FDA may review labeling and intended-use declarations at entry, and importers should ensure their supplier is registered under FDA's food facility registration requirements.
