Last updated: August 2026 dataThe broadest organo-sulfur heading in Chapter 29, this residual category spans an exceptionally diverse range of compounds — from thioglycolic acid and mercaptocarboxylic acids used in cosmetics and PVC stabilizers, to phosphorothioate pesticide intermediates, to cysteine hydrochloride used in food and pharmaceutical applications. China leads US supply, with Spain, India, France, and Japan also significant sources across different compound families. The heading's 25-plus US tariff lines reflect sharp end-use distinctions: pesticide compounds, rubber-processing agents, drug intermediates, and general industrial chemicals each carry separate classification lines with potentially different duty treatment.

Classification within 293090 depends on three layered criteria: (1) aromatic vs. non-aromatic structure, (2) principal end use (pesticide, rubber processing, pharmaceutical/drug, or other), and (3) specific chemical identity for named compounds such as thioglycolic acid (2930904910) or cysteine hydrochloride (2930909210). Importers should obtain a detailed technical data sheet and, where end use is ambiguous, consider a binding ruling request from CBP to avoid misclassification penalties.
Thioglycolic acid (classified under 2930904910 or 2930904915 depending on mixture status) is used in cosmetic formulations such as permanent wave solutions and depilatory products. When imported for cosmetic use, it falls under FDA's jurisdiction and must comply with the Federal Food, Drug, and Cosmetic Act. Industrial-grade imports for PVC stabilizer or other non-cosmetic uses do not trigger FDA review but remain subject to EPA TSCA certification requirements.
