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.

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.

ACS Reagent Bromine

ACS reagent grade bromine for laboratory analysis, consisting of pure elemental bromine (Br2). It is a separate chemical element under Chapter 28 Note 1(a), and is not excluded by Chapter 28 Note 3, so it falls under tariff item 2801.30.00.

Bromine for Water Treatment

Compressed Fluorine Gas Cylinder

Compressed fluorine gas in a high-pressure steel cylinder, consisting of pure elemental fluorine (F2). It is a separate chemical element as defined in Chapter 28 Note 1(a), and is not excluded by any other note, so it falls under tariff item 2801.30.00.

Fluorine Gas Generator Byproduct Flask

A small lecture bottle of fluorine gas, produced by electrolysis of a potassium fluoride-hydrogen fluoride melt, for educational demonstrations. It is elemental fluorine, a separate chemical element under Chapter 28 Note 1(a), and is not excluded by Chapter 28 Note 3, so it belongs under tariff item 2801.30.00.

High Purity Bromine 99.99%

Ultra-high purity bromine at 99.99% for specialty electronics and research, consisting of elemental bromine (Br2). It is a separate chemical element under Chapter 28 Note 1(a), and is not excluded by Chapter 28 Note 3, so it falls under tariff item 2801.30.00.

High-Purity Fluorine Gas for Semiconductor Etching

Ultra-pure fluorine gas in monel-lined cylinders, used for plasma etching in semiconductor manufacturing. It is elemental fluorine, a separate chemical element under Chapter 28 Note 1(a), and is not excluded by Chapter 28 Note 3, so it falls under tariff item 2801.30.00.

Industrial Fluorine for Uranium Enrichment

Bulk fluorine gas shipped in tonnage tube trailers, intended for uranium enrichment via UF6 production. It is elemental fluorine, a separate chemical element under Chapter 28 Note 1(a), and is not excluded by Chapter 28 Note 3, so it belongs under tariff item 2801.30.00.
