HS Code for Potassium iodide

Potassium iodide is classified under HS code 2827.60, which is the specific subheading for iodides and iodide oxides within the Harmonized System. This classification is governed by the rules of Chapter 28, which covers inorganic chemicals and precious metals. According to Note 1 to Chapter 28, the headings of this chapter apply only to separate chemically defined compounds, whether or not containing impurities. Potassium iodide, being a binary compound of iodine and potassium, fits this definition perfectly. It is categorized under the broader heading 2827, which encompasses chlorides, chloride oxides, chloride hydroxides, bromides, bromide oxides, iodides, and iodide oxides. The specific 2827.60 code ensures that this iodine-based salt is distinguished from other halides like chlorides or bromides. The classification remains consistent regardless of the chemical's grade—be it technical, pharmaceutical, or reagent grade—provided it is not prepared as a medicament or put up in measured doses, which would shift the classification to Chapter 30.

Common Misclassification

Potassium iodide is frequently misclassified under HS code 3004.90, which covers medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses. This error occurs when the product is intended for medical use, such as for thyroid protection or as an expectorant. However, unless the potassium iodide is put up in measured doses or in forms or packings for retail sale as a medicine, it must remain in 2827.60. Another common error is confusing it with potassium iodate, which falls under HS code 2829.90. While both contain iodine and potassium, the iodate is an oxoanion salt, whereas the iodide is a simple halide salt.

FAQ

What is the HS code for potassium iodide?

The universal HS code for potassium iodide is 2827.60, which specifically covers iodides and iodide oxides of metals.

Is potassium iodide classified differently if it is used in animal feed?

If potassium iodide is imported as a pure, separate chemically defined compound to be used as an additive, it remains under 2827.60. However, if it is part of a prepared animal feed supplement or premix, it may be classified under heading 2309.
