Importers of Iodides and Iodide Oxides paid $73K in duties in May 2026 — an effective duty rate of 10% on $715K in dutiable value, based on actual customs collections rather than the published tariff schedule. Iodides and Iodide Oxides imports of $1.3M in May 2026 ran 40% below the year-to-date monthly average of $2.1M.
Last updated: May 2026 dataPotassium iodide — classified under its own dedicated line (2827602000) — is the most commercially prominent compound in this heading, serving pharmaceutical, nutritional supplement, radiation emergency preparedness, and photographic applications. Calcium and copper iodides occupy a separate line (2827601000), reflecting their distinct industrial uses in animal nutrition and catalysis. Germany leads US imports under this heading, with India and South Korea also among the top suppliers. Given the pharmaceutical relevance of several iodide compounds, importers of drug-grade material should confirm FDA registration and admissibility requirements prior to shipment.

Potassium iodide (KI) has distinct commercial significance — including its role in thyroid-blocking tablets stockpiled for nuclear emergency preparedness and its use in pharmaceutical and photographic applications — that justifies a dedicated 10-digit line (2827602000). This separation allows customs authorities and trade analysts to track KI flows independently from less commercially sensitive iodide compounds.
Pharmaceutical-grade potassium iodide is subject to FDA oversight as a drug ingredient. The foreign manufacturer must be registered with FDA, and shipments may be subject to examination or detention if the establishment is not on the approved list. Importers should work with a licensed customs broker and confirm FDA compliance before the goods ship. Classification as a drug versus an industrial chemical also affects the applicable entry procedures.
