Last updated: July 2026 dataPotassium sorbate and sorbic acid — both food-grade preservatives regulated by FDA — are the highest-volume commodities within this residual heading, classified at 2916191000 and 2916192000 respectively. China is the dominant supplier of sorbic acid and potassium sorbate globally, and imports from China carry Section 301 tariff exposure, a significant cost consideration for food and beverage manufacturers. The remaining lines (2916193000, 2916195000, 2916196000) capture a broad range of specialty unsaturated acid intermediates used in pharmaceuticals, agrochemicals, and polymer synthesis, with Germany and France as important European sources.

When imported for use as food additives or food-contact applications, these substances are subject to FDA admissibility review. Importers should ensure that shipments are accompanied by documentation confirming food-grade specifications and that the foreign manufacturer is registered with FDA as required under food safety regulations. Classification and admissibility are complex; consult a licensed customs broker or FDA prior to entry.
The distinction among these residual lines turns on whether the product is a free acid, an anhydride or halide, or another derivative form, and on whether it falls within specific US note provisions. Importers should review the relevant chapter notes and, where the product is a novel or multi-functional intermediate, seek a binding ruling from CBP to avoid misclassification.
