Crystalline Iodine
Crystalline iodine is a chemically defined elemental halogen in solid form, meeting the criteria of Chapter 28 Note 1(a) as a separate chemical element. It is not combined with other elements or compounds, and its use is general, not specific. This tariff item covers elemental iodine in all its solid forms, including crystalline.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is chlorine, not iodine
Chlorine is a different halogen element with its own tariff item.
If the product is fluorine or bromine
Fluorine and bromine are other halogen elements classified separately.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the product is pure elemental iodine, not mixed with stabilizers or solvents that could change classification
• Declare the iodine content and form (crystalline) accurately on customs documents
• Verify if any import permits are needed for iodine used in pharmaceutical applications

Industrial Iodine Prills
Industrial iodine prills are elemental iodine in granular form, used for large-scale chemical manufacturing. As a separate chemically defined element, they fall under this tariff item, which covers iodine in all physical forms. The prills are not mixed with other substances, maintaining their classification as pure iodine.
Laboratory Grade Iodine Flakes
Laboratory grade iodine flakes are high-purity elemental iodine in flake form, meeting ACS reagent standards for analytical chemistry. They are a separate chemically defined element, not a compound or mixture, and thus fall under this tariff item. The flakes are suitable for general laboratory use, not specific applications.
Pharmaceutical Grade Iodine Crystals
Pharmaceutical grade iodine crystals are USP-grade elemental iodine used in antiseptics and nutritional supplements. As a pure, chemically defined element, they are classified under this tariff item. The crystals are not formulated into measured doses or retail packs, so they remain in Chapter 28.
Purified Iodine Sublimate
Purified iodine sublimate is elemental iodine purified by sublimation for high-tech applications like semiconductors. It is a chemically defined element in solid form, meeting Chapter 28 Note 1(a). The purification process does not alter its classification as elemental iodine.
Resublimed Iodine
Resublimed iodine is high-purity elemental iodine purified by resublimation, used in laboratory and pharmaceutical applications. It is a separate chemically defined element, meeting Chapter 28 Note 1(a). The resublimation process ensures purity but does not change its classification as elemental iodine.
