Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dissolved in water or alcohol
Iodine solutions or mixtures with other substances are classified as inorganic compounds of nonmetals in heading 2843, not pure elements.
If chemically bound as potassium iodide
Iodide salts of metals like potassium fall under heading 2827 for specific metal salts, excluding pure iodine.
If used as inorganic pigment in dyes
Iodine prepared as a luminophore or pigment for coloring materials is excluded from Chapter 28 per chapter notes and goes to heading 3206.

Import Tips & Compliance
• Verify purity certificate (typically >99.8%) to confirm classification as elemental iodine, avoiding reclassification as compounds
• Include Material Safety Data Sheet (MSDS) due to toxicity and volatility; comply with DOT hazardous material shipping regulations
• Avoid packaging that could lead to misclassification as iodine solution (HTS 2843.29), which requires liquid state documentation
